Product Introduction

General
KYN28 indoor metal-clad switchgear is a complete power distribution device for 3.6~24kV,3-phase AC50/60Hz,single-bus and single-bus sectionalized system. It is mainly used for power transmission of middle/small generators in power plants; power receiving, transmission for substations in power distribution and power system of factories, mines and enterprises, and starting of large high-voltage motor, etc.,so as to control, protect and monitor the system. The switchgear meets IEC298,GB3906-91.In addition to be used with domestic VS1 vacuum circuit breaker, it can also be used with VD4 from ABB, 3AH5 from Siemens domestic ZN65A, and VB2 from GE, etc.,it is truly a power distribution device with good performance.

In order to meet the requirement for wall mounting and front-end maintenance, the switchgear is equipped with a special current transformer, so that the operator can maintain and inspect it in front of the cubicle.

 

Service environment
1.Air temperature: -25℃~+40℃
2.Humidity:Monthly average humidity 95%; Daily average humidity 90% .
3.Altitude :≤ 2500m
4. Ambient air not apparently polluted by corrosive and flammable gas, vapor etc.
5. No frequent violent shake
 

Fully type-tested 
The switchgear has undergone all the tests required by the international (IEC) Standards. Each switchgear unit is subjected to routine tests in the factory before delivery. These tests are intended to provide a functional check of the switchgear based on the specific characteristics of each installation.
