Knkong Electric 33KV switchgear has served the international market over 10 years. 

Appreciate for the hard work of our professional electrical engineering team, the international evaluation of our 33kv switchgear is positive.

 

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.

 

IEC type tests

• Short-time and peak withstand current

• Temperature rise

• Internal arc capability

• Dielectric test

• Making and breaking capacity of circuit-breaker

• Earthing switch making capacity (top application)

• Mechanical operations of circuit-breaker and line disconnector

• IP degree and impact test

 

IEC routine factory tests

• Visual inspection and check

• Mechanical sequence operations

• Cabling check

• Electrical sequence operations

• Power frequency withstand voltage

• Measurement of the resistance of the main circuits

• Secondary insulation test
