(Summary description)1. Busway maintenance is convenient: busway is almost maintenance-free. Routine maintenance is usually to measure the temperature rise of the outer casing and the core bolt, and the temperature rise of the joint of the inlet box. If the core bolt is 4.8, it needs to be tightened regularly. If you use 8.8 high-strength bolts, you don't have to be strong on a regular basis.

Information
1. Busway maintenance is convenient: busway is almost maintenance-free. Routine maintenance is usually to measure the temperature rise of the outer casing and the core bolt, and the temperature rise of the joint of the inlet box. If the core bolt is 4.8, it needs to be tightened regularly. If you use 8.8 high-strength bolts, you don't have to be strong on a regular basis.
 
2. Busbar slot overload capability: Busbar slot overload capability is strong, depending on the insulation material used for it. The insulation material used for busbar slot is over-supported with a working temperature of 105 °C. The operating temperature has been developed to be 140. Radiation cross-linked flame-retardant tape and radiation cross-linked polyhydrocarbon heat shrinkable tube above °C. The insulation materials used for cables generally have a working temperature of 95 ° C and 105 ° C, so the overload capacity of the busway is far greater than that of the cable.
 
3. Busbar slot tapping is convenient: the so-called plug-in busbar slot is that it uses the plug-in method to connect the power of the trunk line to the branch line, so the tapping is very convenient. Prefabricated branch cable has the disadvantage of being customized to the factory; its branch connection method uses an open "C" type hoop. Can it guarantee the tightening force for a long time? Plus each branch head is expensive, so the prefabricated branch cable The application has not been widely used so far. Any floor needs to be cut off, and the busbar does not need to be powered off. As long as it is empty, remove the busbar box. However, it is very dangerous to cut off the branch power supply of the prefabricated branch cable and operate it under power.
 
4. The busway can prevent overload and fire. The insulation layer and the outer skin of the ordinary cable will burn. The flame-retardant cable will also burn under the flame. It will not burn after the flame leaves. The fire-resistant cable will not burn, but the price is expensive. Fire-resistant cables are used only for power sources that are not allowed to be powered off. The busbar housing is made of steel and will not burn. Even if the insulation of the copper bar burns, the flame will not get out of the busway.
 
5. Busbar slot heat dissipation performance: The insulation material of the cable (core wire insulation and sheath insulation) is both an insulating material and a heat insulating material. Therefore, when the power cable is laid in the bridge, a maximum of 2 layers can be laid. .
 
The busway uses air to dissipate heat and dissipates heat through a tightly-contacted steel casing, so its heat dissipation performance is comparable to that of a cable.
