Product Applications

Metallurgical and Steel Plants: Electric arc furnaces and other equipment in steelmaking consume massive amounts of electricity. The plant's on-site 110KV/220KV high-voltage substations require this accessory to ensure continuous production.

Petrochemical and Coal Chemical Industries: Petrochemical industrial parks have extremely high requirements for power supply reliability. The density meter on the high-voltage circuit breaker can provide timely warnings, preventing production stoppages and secondary safety disasters caused by unannounced power outages.

Hydropower Plants: The high-voltage outgoing switchgear in the substation must be kept insulated using this device.
