◆Product Features

1.The cabinets and partition board adopting hot-dip Al-Zn alloy-coated steel sheet and frame adopting assembled structure makehigh overall intensity and good earth continuity.

2.The cabinet is combined type and the handcart of breaker is floor structure type.

3.The new composite insulating vacuum circuit breaker has the characteristics of interchangeability and simple replacement.

4.The handcart adopts screw propulsion mechanism,which moves the handcart easily and prevent mis-operation to damage thepropulsion mechanism.

5.All the operations could be done when the cabinet door is closed.

6.The interlocking between the main switch,the handcart and the switch cabinet adopts the mandatory mechanism of mechanicallocking,meeting the functions of five-preventions.

7.The cable room is spacious and can be connected to a number of cables.

8.The degrees of protection is IP4X,which effectively prevents the equipment from being invaded by sundries and insect pests.

9.The product runs safely and reliably through the harsh condensation,filth and internal arc tolerance test.
