LongXing FCK air type busbar is applicable to the AC 3-phase 3-wire, 3-phase 4-wire and 3-phase 5-wire power supply and distribution system of which the frequency is 50Hz(60Hz), the rated operational volatage is 660V and the operational current is 100-5000A and the most ideal power supply and distribution device for modern large and medium sized enterprises, high building to introduce engineering experimental base. For the busbar with socket, it is very convenient to lead to power branch by pluging switch box. The installation of bus duct can be from the transformer to power distribution cabinet directly and it also can be from the low-voltage switchgear to the power distribution system as power distribution main circuit.
