Model

Products feature

1) This product is applicable for our own made GPVN-12kV/17Kv/24kV embedded or insulating sleeve vacuum circuit breaker or ABB’s VD4 vacuum circuit breaker.
2) Our production configuration GPVC vacuum contactor – fuse combination or ABB company’s VC vacuum contactors, which can be composed of F-C loop cubicle, to meet the electricity system of power plants and demand of other industrial and mining enterprises.
3) Using excellent aluminum-zinc clad steel plate by precision CNC machining equipment assembled into the cabinet, and the use of double bending process, greatly improve the strength of the cabinet.
4) Door surface by epoxy resin electrostatic powder spray process, resistance of corrosion, oxidation, impact and strong adhesion.
5) Cabinet fully enclosed structure is realized fully armored, the functional units are completely separated. When the door is closed, it can achieve the operation of circuit breaker and earthing switch.
6) Precision screw drive mechanism, ensure the trolley with good interchangeability.
7) Perfect primary plan to meet the various needs of users, and enables double trolley plan.
8) Fast grounding switch for earthing and short circuits, and to achieve electric (Motorized) operation.
9) Simple and effective “Five Safety” interlock mechanism can reliably prevent misuse and ensure operator’s safety.
10) Switchgear is belonging to Arc-proof type, on the top of bus compartment, Vacuum circuit breaker compartment, and cable terminal compartment are equipped with pressure relief devices.
11) Cable compartment has ample space, can be easily connected to a plurality of cables, and make sure the installation height of the cable plug.
12) Strict protection rating (IP4X), to effectively prevent foreign matter or pest invasion.
13) Optional secondary system following the security monitoring device has a self-diagnostic function and data communication, intelligent integrated computer, to achieve remote control, remote telemetry, remote viewing, remote adjustment.
14) Meet GB3906, GB / T11022, DL404 and IEC60298, IEC62271-1 standards, and through a comprehensive test type test and plateau test (3000 m).
15) Passed electromagnetic compatibility tests in the high voltage equipment test laboratory.
