Product Detail

indoor high voltage AC grounding switch JN15-12KV 7.2KV 31.5KA 210  for switchgear from JUCRO Electric

The main purpose
JNI5-12I7.21/31.5 indoor high-voltage grounding switch is an internationally advanced product developed by our company using advanced technology. Its structure is assembled. After comprehensive assessment, the performance meets the requirements of GB1985-2004 "AC high-voltage isolating switch and grounding switch" and IEC62271-102:2002, suitable for 3-12kV three-phase AC 50Hz power system: it has short-circuit locking ability to protect the switch Other electrical equipment in the equipment is not damaged, it can be used with various high-voltage switchgears, and can also be used as grounding protection for high-voltage electrical equipment maintenance.

Environmental conditions
1. The altitude does not exceed 1000m;
2, ambient air temperature: upper limit +40 ° C, lower limit -25 ° C;
3. The seismic intensity does not exceed 8 degrees:
4. The daily average relative humidity is not more than 95%, and the monthly average is not more than 90%:
5. Pollution level: II.

♦ Ordering instructions
1. When ordering the grounding switch, please indicate the product model, distance and whether it is equipped with a live display (and indicate the model of the monitor).
2. The user should indicate the up and down position of the moving and static contacts when the grounding switch is installed in the cabinet.
3. If you have special requirements, please contact us.
