IP54 insulation The insulation of IP54 is made of insulation material coated with polyester film, which is resistant to high temperature of 130 ℃. Due to the inability of the material to tightly adhere to the conductor, there is still air between the insulation materials and between phases, which can only prevent splashing water from entering. When encountering higher-level water intrusion, water will enter the busbar body and conductors through gaps, causing a short circuit. Alternatively, polyester film insulation can be used. When condensation occurs, the insulation of the busbar will be tested, posing a risk of accidents. IP65 insulation Our company uses epoxy resin vulcanized insulation material with a higher temperature resistance level (180 ℃ H level) for IP65 insulation. The insulation is integrated into a covered conductor, ensuring contact between the insulation layer and the conductor and a smooth surface, thereby ensuring that the heat wave is quickly transmitted and dissipated in a uniform arc waveform under the polymer radiation material. Due to the epoxy resin vulcanization insulation integrated molding of the covered conductor, the insulation layer is in contact with the conductor, and water cannot come into contact with the conductor. This not only improves the waterproof level, but also eliminates condensation between the insulation layer and the conductor OE home has strong R&D resources, focusing on epoxy resin vulcanization insulation technology, and has an excellent R&D team and technical personnel. The company's entire series of busbar products have obtained CQC certification, as well as international authoritative Kema Keur certification and UL certification. We are still continuously conducting product research and development, adopting advanced thermodynamic applications and manufacturing methods to provide high-performance and high-quality products to our customers. Welcome and look forward to working with you!                                                                              

      As a vital component in the field of power transmission and distribution, bus ducts play a crucial role in industrial and commercial sectors. With the rapid advancement of technology and the increasing emphasis on sustainable development, bus ducts are encountering numerous new opportunities and challenges.       As a critical component in power transmission, enhancing energy efficiency in bus ducts holds immense significance for energy conservation and carbon emission reduction, aligning with the principles of sustainable development. The development and utilization of environmentally friendly materials for energy-saving and consumption-reducing bus duct designs can effectively mitigate natural resource consumption and environmental pollution.         In the production and utilization of bus ducts, significant emphasis is placed on recycling, minimizing environmental impact, and advocating the implementation of sustainable development principles. This involves the development and application of high-temperature resistant materials suitable for industrial environments, thereby enhancing the heat resistance and electrical performance of bus ducts and ensuring the stability of power transmission.        Ohory specializes in epoxy resin insulated bus duct technology. The epoxy resin bus ducts produced by Ohory Technology exhibit excellent insulation performance. They are not only waterproof and dustproof but also provide complete coverage to the conductors, ensuring a flat and seamless insulation layer in contact with the conductors' surface. Additionally, during the electrification process, the busbar trunking is submerged in a fish tank. Even with water entering the insulation conductors from various angles, the bus duct can still maintain normal electrical functionality. Remarkably, the fish in the tank remain alive! These bus ducts possess exceptional pressure resistance and fire resistance, being the only insulation type that remains undamaged for 10 seconds under flame grilling at temperatures as high as 1300°C. Furthermore, they dissipate heat rapidly and pose no harm if touched by the skin. The epoxy coating also provides strong resistance against oxidation and salt spray. By completely eliminating contact between conductors and air, the insulation layer remains undamaged even after undergoing 1800 hours of salt spray testing. These bus ducts exhibit remarkable toughness and strength, allowing them to withstand the rigors of thermal cycling without damage.        This insulation technology has undergone rigorous evaluation by the environmental protection department, ensuring its compliance with environmental standards. Its high-temperature conduction and short endurance characteristics effectively reduce losses and save on electricity expenses. The process is fully automated with PLC control, resulting in an extremely smooth, uniform, and aesthetically pleasing surface finish. As temperature influences the resistance of conductors, the use of epoxy resin with low resistance and excellent heat dissipation properties helps reduce electricity consumption, promoting energy conservation. The efficient and automated vulcanization production line, along with the physical operations involved in the pre-treatment process, contribute to sustainability. The vulcanization layer can be reused while maintaining the same current load, allowing for the reduction of conductor size and minimizing the demand for copper mining. These benefits collectively emphasize energy conservation and environmental protection.         Driven by the application of new technologies, sustainable development, and innovative design, bus ducts have promising development prospects. In the future, with the continued advancement of technologies and ongoing material innovations, bus ducts will further adapt to the evolving demands of industrial and commercial sectors. They will inject new vigor into power transmission by offering higher efficiency and enhanced reliability.

Busbar Material And Usage Analysis Busduct is a type of transmission equipment that uses copper or aluminum bars as conductors, and is protected by insulation materials and casing to achieve current transmission and control. Compared with traditional cables and steel pipes, compact busduct has higher current carrying capacity and smaller volume, making them widely used in various occasions such as shopping malls, factories, and residential buildings. As a component of power transmission and distribution systems, it is used to provide efficient and reliable power supply in industrial and commercial buildings. 1.Comparison inconductivity performance The resistivity of copper is 0.0185mm2/m, and the resistivity of aluminum is 0.0283mm2/m. If the conductivity of copper is 100%, it is accurate; The conductivity of industrial pure aluminum is about 60% of that of copper. Overall, for conductors with a unit cross-sectional area, the conductivity of copper conductors is 35% to 40% higher than that of aluminum alloy conductors, and their conductivity is even better. 2.Compared in terms of portability From the perspective of conductor density, aluminum is 2.7g/cm ³， Copper is 8.9g/cm ³ ， The density of copper is about 3.3 times that of aluminum, which results in the weight of aluminum being lower than the mass of copper under the same current carrying capacity. Therefore, when using copper busduct, it is necessary to consider the load-bearing issues in the busbar structure and engineering installation. 3.Comparison of mechanical properties Copper has good chemical stability, as well as high strength and hardness. Compared to aluminum busduct, it has better mechanical properties and resistance to high-temperature deformation. However, aluminum is more active, but after adding trace elements for heat treatment, it can be made into aluminum alloys to improve chemical stability. Some aluminum alloys also have much stronger strength than copper. From the perspective of mechanical strength and hardness, aluminum alloy conductors can achieve the mechanical performance advantages of copper conductors. 4.Comparison of conductor cross-sections Due to considerations of resistance and strength, under the same current carrying capacity, the cross-sectional area of aluminum alloy conductors is larger than that of copper conductors, and copper busduct has more advantages when used in places with space limitations. 5.Comparison of economic performance Copper resources in nature are relatively limited, and prices are relatively high; And aluminum resources are relatively more abundant, with lower prices. Taking copper busduct and aluminum alloy busduct with equivalent conductivity as examples, combined with the special process in the manufacturing of aluminum conductor busduct, the cost of aluminum conductor busduct is about 3/5 of that of copper with the same current carrying capacity. 6.Comparison of electrical energy losses In today's world where energy efficiency is a concern, electrical energy loss is increasingly becoming a technical indicator of public concern in the daily use of various low-voltage devices. Electric energy loss is an important factor affecting the efficiency of busduct operation, which is usually proportional to the resistance of the busduct. Due to the lower resistance of copper conductors compared to aluminum alloy conductors, the electrical energy loss of copper busduct is lower than that of aluminum alloy busduct under the same rated current.

In the 1990s, direct cables played an important role in the transmission and distribution of low-voltage power distribution systems. However, since the 1990s, systematic research on the use of busbar ducts has been gradually introduced and developed, and it has quickly been widely used in power supply and distribution design projects. Compared with traditional power transmission technology equipment management, it has its own unique performance development potential, such as large carrying capacity, strong overload capacity, convenient tapping, good heat dissipation, and convenient maintenance.   1. Performance characteristics of ordinary bus ducts and cables Multi-core cable is a complete cable composed of multiple insulated cores twisted and wrapped with an outer sheath. The number of insulated cores of power system cables is usually 1, 2, 3, 4, 5 cores, 4+1 and 3+2 cores. The main characteristics of cables are flexibility and adaptability to the environment, but they also have inherent limitations. The following is a performance comparison of bus ducts and cables from several main aspects.   a) Carrying capacity The structural cross-sectional area of the low-voltage control cable with carrying capacity is 1000mm2, and the rated operating current is 1600A. Because such large cables are bulky and heavy, they are rarely used in actual projects. In general projects, cables of 400mm2 and below are commonly used, and multiple cables are needed to achieve simultaneous power supply. The rated working current efficiency of the bus duct can reach 6300A, and its strong current carrying capacity is the foundation of the cable.   b) Overload capacity Whether it is a cable or a bus duct, its overload capacity depends on the operating temperature of the insulation material used. The working environment temperature of bus duct insulation structural materials is 105°C. We developed radiation cross-linked flame-retardant winding tape (PER) and radiation cross-linked polyhydrocarbon heat shrinkable tubes whose temperature is above 140°C during students' work. The normal operating temperature of the insulation material used for mesh cables is 90°C and 105°C, and the normal operating temperature of the irradiated cross-linked cable is 125°C. Therefore, the overload protection capability of the bus duct has a far greater impact than the overload problem capability of the cable.   C) Bus duct installation The installation of bus duct generally adopts plug-in installation method. The so-called plug-in bus duct uses a plug-in method to branch the power supply of the main line to the branch line. There are plug-in box openings every few meters, so branching is very convenient. However, the cables require on-site splicing and have poor reliability, and even prefabricated branch cables have their shortcomings. The obvious disadvantage of branch cables is mainly that they require customized branch connection technology equipment from the enterprise factory, which can usually use open data "C" type hoops. Over time, whether this type of hoop can ensure sealing is also a question. In addition, branch cable branch heads are expensive, so prefabricated branch cables are still not widely used. When installing a branch network cable, you need to cut off the power supply on the floor. When installing the bus duct, you do not need to cut off the working power supply. You only need to remove the plug box of the bus duct under no-load conditions. But to cut off the branches of prefabricated branch cables for power supply, it is very important and dangerous to operate live equipment.   d) Fire resistance The insulation and sheath of ordinary cables will burn out. Even flame-retardant cables will burn under an ongoing flame, and we only increase burning after the flame can leave. Fire-resistant cables will not burn but are expensive. Fire-resistant cables are only used in places where cutting off the power supply is not allowed, such as fire alarm circuit systems. The busbar casing is made of metal and will not burn. Even if the insulation material of the copper busbar burns, the flame will not threaten the outside of the busway.   e) Heat dissipation performance The insulation layer and outer sheath of the cable are both an insulation layer and an insulating layer. Therefore, in order to maintain the heat dissipation of one cable, when the cable is laid in the cable tray, it is allowed to lay two layers. The main reason is to consider heat dissipation issues. The bus duct uses air conduction to dissipate heat through the steel shell in close contact, so its heat dissipation performance is better than that of cables.   f) Operation and maintenance Maintenance of bus ducts is relatively simple. In the daily maintenance of the bus duct, it is usually to measure the temperature rise of the shell and core bolts, the temperature rise of the inlet box joints, etc. If the core bolts are 4.8, they need to be tightened regularly. If 8.8 high-strength bolts are used, There is no need to tighten regularly. However, due to the limitations of materials that are easy to wear, easy to age, and have short lifespan, cables need to be regularly inspected, maintained, or even replaced.   2. Installation and construction Although installation through cable laying in the line direction can be flexible and convenient, the cable enterprises in the project are generally supported by bridges. Therefore, during the cable construction process, it is necessary to install the bridges first and then lay the cables step by step. Bus duct installation does require professional installation technology, but it can only be installed in one go according to the product standard installation procedures. In addition, the bus duct has a compact structure and takes up less space. It is easy to arrange the piping and wiring space and is easy to install and use. Of course, for small current lines below 400a, due to the small cross-sectional area of the selected cables and the small number of cables, the use of cables is flexible.   3. Power supply system The busbar power supply system is usually a trunk line leading from the power distribution center to provide flexible power supply in a decentralized form, while the cable power supply is limited by factors such as difficulty in tapping, small carrying capacity, and difficulty in decentralized control. It is usually "point-to-point" power. Especially in the power supply control system of high-rise management buildings, bus ducts are more prominent than cable conductors. In the traditional wired power supply method, each floor needs to be laid separately, and there are a large number of cables. This technology-intensive laying method has poor heat dissipation, takes up a lot of space, makes accident inspection and learning difficult, and makes maintenance and management difficult. Bus duct power supply enterprises can use a single central bus duct system and set up a plug-in box with corresponding information capacity on each floor for effective distribution. This method makes the branching extremely flexible, and each branch has a plug-in box to protect the branching capacity. Therefore, the use of bus duct is safe, simple and reliable.   4. Economic cost Compared with cables, bus ducts generally use better materials and relatively complex processes, so the expected investment cost is generally greater than cables. However, in the long run, more bus ducts will be used. However, the service life of bus duct is generally 30 to 40 years, while the service life of ordinary cables is only about 15 years. As long as the busway system is installed and operated according to specifications, there is no need to replace components other than a routine inspection of the surroundings. However, cable companies often experience phenomena such as aging of a joint and falling off of the insulation layer, and need to replace a certain section of the cable. In addition, many powerful bus duct manufacturers on the market have introduced aluminum conductor bus ducts, which have been widely used in large buildings. The purchase cost price of this kind of production bus duct is much lower than the price of traditional cable tray, but the performance is higher than other cables. For users who lack the funds to invest in bulk, this type of bus duct can be used.
