Built for the Toughest Jobs
The Heavy Duty Vacuum Relay is designed for high-load applications. We come from the original State-owned No. 897 Factory. We have inherited the strict quality concepts and advanced manufacturing techniques of a military enterprise. The relay uses a reinforced mechanical structure and wear-resistant contact materials. This allows it to work reliably under heavy loads and frequent operations.
Resists Wear and Environmental Damage
This relay uses a ceramic vacuum seal. The vacuum provides excellent insulation. It also stops contact oxidation and arc damage. In heavy-load use, frequent switching causes contact wear. But our Heavy Duty Vacuum Relay handles this well. The arc cannot sustain itself in a vacuum. This means contact burning is very small. The relay lasts much longer than ordinary relays. Our quality management covers every step from raw materials to final shipping. Every product meets strict quality standards. Our products have won 45 national and provincial awards for excellence.
Safe in Hazardous Environments
The Heavy Duty Vacuum Relay is used in harsh and heavy-load environments. These include intrinsically safe and explosion-proof applications. The relay is also used in deep well oilfield equipment. It serves automation systems for high-voltage and high-power equipment. The relay works well in flammable, explosive, and corrosive environments. It is also used in airport runway lighting systems and undersea power distribution. In the military, our product supports aviation, aerospace, and shipbuilding power control systems.
