Product Details

Withdrawable vacuum circuit breaker for medium voltage use KYN28A-12

Voltage: 12KV

Current: 630-2000A

Type: withdrawable

General

The rated voltage of KYN28-12KV indoor switchgear is 3.6～24kV, three-phase, AC, 50/60Hz, single bus or single bus segmented system complete set of power distribution equipment. It is mainly used for the power transmission of small generators in power plants, the power distribution of production enterprises and the power transmission and transmission of substations in the power system, and the start of large high-voltage motors. The role is to control, protect and monitor the system.

It conforms to IEC and GB3906-91 standards, and can be used with vacuum circuit breakers such as domestic VS1 vacuum circuit breaker, ABB's VD4, Siemens domestic ZN65A 3AH5, GE's VB2 and other vacuum circuit breakers.

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 device passes all tests required by international (IEC) standards. When each switchgear goes through regular factory tests before leaving the factory.

These tests are a functional inspection of the equipment based on the characteristics of each device.
