Product Overview

As a new type of distribution wire, plug-in bus duct has emerged. Compared with traditional cables, it fully demonstrates its * performance in high current transmission. At the same time, due to the use of new technologies and processes, the contact resistance and temperature rise at the two ends of the bus duct and the junction of the distribution port are greatly reduced. High quality insulation materials are also used in the bus duct, thereby improving the safety and reliability of the bus duct and making the entire system more *. This series of plug-in busbar trunking is particularly suitable for high-rise buildings, multi story industrial plants, standard factories, workshops with dense machine tools, workshops with variable product processes, the renovation of old workshops, laboratories, exhibition halls, sports venues and other places. It is used for power supply and distribution in stores. Its characteristics include series matching, commercial production, small volume and large capacity, short design and construction period, easy assembly and disassembly, safety and reliability, and long service life.

Product features

1. Convenient tapping of busbar trunking: The so-called plug-in busbar trunking refers to its use of plugging to tap the power supply of the main line to the branch line, making tapping very convenient. The disadvantage of prefabricated branch cables is that they need to be customized from the factory; The branch connection method adopts an open "C" - shaped clamp. After a long time, can the clamping force be guaranteed? Due to the high cost of each branch head, prefabricated branch cables are still not widely used today. Any floor needs to cut off the power supply, and the bus duct does not need to be powered off. As long as it is unloaded, the plug-in box of the bus duct can be removed. But it is very dangerous to cut off the branch power supply of the prefabricated branch cable while it is live.

2. Strong overload capacity of busbar trunking: The strong overload capacity of busbar trunking depends on the high working temperature of the insulation material used. The insulation material used for busbar trunking is made of materials with a working temperature of 105 ℃. Radiation cross-linked flame-retardant winding tape (PER) and radiation cross-linked hydrocarbon heat shrink tubing with a working temperature of over 140 ℃ have been developed. The insulation material used in cables generally operates at temperatures of 95 ℃ and 105 ℃, so the overload capacity of bus ducts is much greater than that of cables.

3. Bus ducts can prevent overload and fire: On August 27, 2000, the Ostankino TV Tower in Moscow, Russia, was hit by numerous disasters2、 High rise buildings in Europe are engulfed in raging fires. The reason is caused by cable overload; The shutdown of three converters at Baosteel was also caused by a cable fire. The insulation layer and outer skin of ordinary cables will burn, and flame-retardant cables will also burn under flames. They only do not burn after the flame has left, while fire-resistant cables will not burn, but they are expensive. Only fire-resistant cables are used for power supplies that are not allowed to be cut off, such as firefighting. The outer shell of the bus duct is made of steel and will not burn. Even if the insulation material of the copper bar burns, the flames will not spread outside the bus duct.

4. Good heat dissipation performance of bus duct: The insulation material of the cable (core wire insulation and outer insulation) is both insulation material and thermal insulation material. Therefore, when laying power cables in the bridge, it is allowed to lay 2 layers more, and the reason for this is to consider heat dissipation. The busbar duct utilizes air conduction for heat dissipation and dissipates heat through a tightly contacting steel casing, thus its heat dissipation performance is comparable to that of cables, and the cable heat dissipation performance is evident.

5. Convenient maintenance of bus ducts: Bus ducts require almost no maintenance. Daily maintenance usually involves measuring the temperature rise of the casing and core bolts, as well as the temperature rise of the joints in the incoming box. If the core bolts are of grade 4.8, they need to be tightened regularly. If high-strength bolts of grade 8.8 are used, they do not need to be reinforced regularly.
