Armored Mid-Insert Metal Closed Switchgear - High Voltage switchgear

Introduction - Armored Mid-Insert Metal Closed Switchgear [High Voltage switchgear] 1. KYN28A-12(GZS1) Armored Mid Insert Metal Closed Switchgear (hereinafter refers to Switchgear) is an indoor three-phase AC 50Hz power distribution equipment. It is used in accepting and distributing 3.6~12KV network power and can control, protect and monitor the circuit. The Switchgear meets such standards as:GB3906, DL404, IEC-298, etc. It has the “five defenses” function, which could prevent misuse of the circuit breaker, pushing the loaded handcart, closing charged ground switch, electric transmission of ground switch at the grounding position and mislead into the charged interval. It can be applied to VS1, ZN63, Schneider EV12 Vacuum circuit breaker as well as ABB VD4 vacuum circuit breaker and VC series vacuum contactor.
2. KYN28A-12(GZS1) Armored Mid Insert Metal Closed Switchgear produced by our company has passed national CQC voluntary product authentication and model test.
Structure - High Voltage switchgear
1. The Switchgear is composed by the fixed cabinet body and the movable component (handcart) these two parts. The shell and separation board of each functional unit are bolted by the aluminum –zinc steel plate. The Switchgear shell protection rank is IP4X and when the circuit breaker room is open is IP2X.
2. KYN28A-12 Switchgear can be applied to VSl, ZN63, EVl 2 and VD4 vacuum circuit breaker handcart. It can be installed on the wall so as to save the space and increase the security and installation flexibility of Switchgear.
