VD4 VCB Vacuum Circuit Breaker High Voltage Switchgear Indoor 12kV
13.8kV 24kV 35kV

 
Product introduction:
The vacuum circuit-breakers of type VD4 on with drawable parts for 36 kV or 40.5 kV rated voltage are intended
for indoor installation in air-insulated switchgear systems. Their switching capacity is sufficient to handle any
conditions arising from switching of equipment and system components under normal operating and fault
conditions, particularly short-circuits, within the parameters of their technical data. Vacuum circuit-breakers have
particular adswitching frequency in the working current range and/or where a certain number of short-circuit
breaking operations are expected. Type VD4 vacuum circuit-breakers are suitable for autoreclosing, and have
exceptionally high operating reliability and long life. The vacuum circuit-breakers designed in column form, are
supplied as withdrawable modules. Their basic structure is shown in figures 3/1,3/2,3/7 and 3/8.
1.2.1 Switchgear manufacture
The switchgear complies with the following specifications in accordance with GB, IEC and the relevant DIN VDE
publications respectively.
GB/T 11022, IEC 60694 and DIN VDE 0670 part 100, "Common specifications for high voltage switchgear and
controlgear standards".
GB 1984 and IEC 62271-100, "High-voltage alternating-current circuit-breakers".
