Busbars and busbars are widely used. Its unique advantages are gradually replacing traditional cables, but busbars cannot be used in some places. Let's take a look.

1. The busbar and busbar slot are convenient for tapping: The so-called plug-in busbar slot is used to connect the power supply of the trunk line to the branch line. Therefore, tapping is very convenient.

2. The busbars and busbars have strong overload capacity: busbars and busbars have strong overload capacity, depending on the insulation material used for it has a high working temperature, and the busbar insulation materials are all made of materials with a working temperature of 105°C. Work has now been developed. Radiant cross-linked flame-retardant tapes (PER) and radiation cross-linked polyhydrocarbon heat shrinkable tubes at temperatures above 140°C. The insulating material used in the cable is normally operating at 95°C and 105°C, so the overload capacity of the busbar is far greater than that of the cable.

3, busbars, busbars can prevent overload fire.

4. The heat dissipation performance of the busbars and busbars is good: the insulation materials of the cables (core insulation and sheath insulation) are both insulating materials and thermal insulation materials. Therefore, when the power cable is laid in the bridge, it is allowed to lay up to two layers. Consider heat dissipation.

5. The busbars and busway are easy to maintain: The busbars and busbars need little maintenance. The daily maintenance is usually to measure the temperature rise of the shell and the core bolts, the temperature rise of the junction box, etc. If the core bolt is 4.8 grade, you need to Regular tightening, if you use 8.8 high-strength bolts do not have to be regularly sturdy, volcanic rock cast bus even does not require maintenance.
