GN 30

GN30 is a mature indoor high voltage isolation switch suitable for 12kV medium voltage power distribution systems. Complying with IEC and GB standards, it is widely installed in indoor switchgears and substations for circuit isolation and power cut-off protection.
Adopting high-conductivity copper conductive parts and optimized contact structure, the GN30 isolator features low contact resistance and stable current carrying capacity, avoiding overheating during long-term operation.
Equipped with high-strength insulating supports, the product provides excellent insulation performance and strong dielectric resistance, ensuring obvious isolation gaps and improving power system operation safety.
The reasonable mechanical transmission structure ensures flexible and stable opening and closing operation. It boasts high mechanical stability and long service life, suitable for frequent operation scenarios.
With compact overall structure and small installation space, GN30 is easy to install and debug with low daily maintenance, effectively reducing power distribution operation costs.
As core isolation equipment for indoor 12kV power systems, GN30 high voltage isolator switch features stable performance and high safety. We provide global customers with factory direct supply, complete certifications and professional after-sales service.
