1. This switchgear is case metal-enclosed structure. In accordance with the national standard GB3906 and

international standardIEC298, protection degree IP2X. The metal-enclosed structure effectively prevents

short-circuit failure by intruders .

2. When air insulation distance between polar to polar or polar to ground ≤125mm, porcelain support insulators

(≥8000N) is applied. All these ensure higher insulation intensity and stability.

3. Breakers, both upper and lower insulation switches, grounding switches and interlock mechanisms between

doors all takes force mechanical lock mode to meet the requirement of "five- prevention"

Factory price supply electrical power distribution equipment for switchgear distribution panel board

The equipment is suitable for distribution system in power plants, petroleum,chemical, metallurgy, textile, and high-rise construction industries; in places of large power plants and petrochemical systems with high degree of automation and requiring computer interface, used as low-voltage power distribution equipment device set in power supply system, power distribution system, motor centralized control, low-voltage power distribution equipment and reactive power compensation in three-phase AC frequency of 50 (60) Hz, rated working voltage of 380V (400) V, (600) V, rated current of 4000A and below.

Product features

●Increase the heat capacity of the adapter, and significantly reduce additional temperature rise of connector, spacer plates due to the temperature rise in adapters.

●Clear and reliable division between functional units and compartments.

●Flat-mounted arrangement of bus bar permits good driving and thermal stability.

●The connecting with external cables is completed within the cable compartment, and the cable can be pulled in and out. The zero sequence current transformers are set in the cable compartment, easy for installation and maintenance.

●By the reduced current limiting reactors' matched short-circuit current, the bus bar's voltage could be stabilized at a certain value, the parts'short-circuit components strength requirement could also be reduced.

●The drawer unit has sufficient number of secondary plug-in components to meet the requirement for the numbers of connection points for computer interface and automatic control circuits.
