Product Overview
The KYN28A-12 (GZS1) type indoor metal-clad central position switchgear (hereinafter referred to as switchgear) is a new type of switchgear developed by our company based on the introduction of advanced technology from abroad. It is suitable for three-phase AC 50Hz, rated voltage 3.6~12kV, rated current up to 4000A single bus and single bus section power systems, for receiving and distributing electrical energy, and controlling, protecting and monitoring circuits.
The switchgear is equipped with VS1 vacuum circuit breaker or imported VD4 vacuum circuit breaker, and the cabinet body is made of high-quality cold-rolled steel plate after CNC processing and bolted assembly. The protection level of the enclosure is IP4X, and the protection level when each compartment and circuit breaker room door is opened is IP2X. The switchgear has various functions such as preventing the operation of the circuit breaker with load, preventing the closing of the grounding switch with power, preventing the accidental entry into the live compartment, and preventing the closing of the circuit breaker with the grounding switch.
This switchgear has the advantages of small size, light weight, beautiful appearance, high degree of generalization of components, small land occupation, good interchangeability of components, perfect “five prevention” function, and convenient installation and maintenance.
