20kV Medium Voltage Switchgear/ Air Insulated Metal Clad Switchgear

Standards

The switchgear and main apparatus contained in it comply with the latest IEC Standards:
• IEC 62271-1 for general purposes
• IEC 62271-200 for the switchgear
• IEC 62271-102 for the earthing switch
• IEC 62271-100 for the circuit-breakers
• IEC 60071-2 for the insulation coordination
• IEC 62271-106 for the contactors
• IEC 60265-1 for the switch-disconnectors
• IEC 60529 for degree of protections

Service environment:
a) Air temperature:Maximum temperature: +40℃; Minimum temperature:-25℃

b) Humidity:Monthly average humidity 95%; Daily average humidity 90% .

c) Altitude above sea level:Maximum installation altitude: 2500m

d) Ambient air not apparently polluted by corrosive and flammable gas, vapor etc.

e) 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.

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
