Difference between air busway and compact one

The difference between air busway and compact one:
1. Different insulating way

there is a certain gap between copper rows of air bus slots, that is to say, the insulation between copper rows mainly depends on air. The insulating medium between copper rows of intensive bus slots (also known as closed bus slots in many regions) is organic insulating material.

2. Appearance: air bus groove is to belong to up and down general thick, and intensive bus groove is in joint place, can become big, individual feeling resembles big head.
3. USES: better dampproof effect of air, used in humid environment like shaft; Dense bus slot current is relatively large, used in the main lines such as connecting bus.
4. Heat dissipation: the heat dissipation of air type mainly relies on the convection of air in the tank and outside to transmit heat, and the efficiency of heat dissipation is relatively low.

5. Prices: price of air busway is a little higher.
6. Protection levels: IP of the compact buway better,generally IP54 and above.
7. Safety : If something enter busduct, shor-circuit might occur for air busway.But it will never happen to compact type.
8. Chimney effect: in case of fire, there will be chimney effect in air bus duct. Intensive does not.
