Product Features

  1. The cabinets and partition board adopting hot-dip AI-Zn alloy-coated steel sheet and frame adopting assembled structure make high overall intensity and good earth continuity.
  2. The cabinet is a 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 the propulsion 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 mechanical locking, meeting the functions of five- preventions.
  7. The cable room is spacious and can be connected to a number of cables.
  8. The degree 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.
