Enterprise code
1. Operational safety. We can provide special security for our users through the following safety measures.
◆ Integratedthree-positionload switch
◆ Circuit breaker adopts load switch instead of disconnecting switch,which is safer and more reliable.
◆ The primary side is fully enclosed to provide protection from accidental contact.
◆ Mechanical interlocks that meet the requirements of the five defenses
◆ The power-carrying display can provide the indication of the power-carrying of the incoming and outgoing lines.
2. Reliable operation. Fully enclosed design, all 10kV switch and bus charged body are sealed in the 3mm stainless steel plate welded into the air box; with silicone rubber cable plugs, to achieve the cable head fully insulated and fully sealed so as not to be dusty.
External environmental influences such as dust, humidity, small animals.
◆Spring energy storage operating mechanism, can be manually or electrically operated
◆Panel molded line drawing provides switch position indication
◆The cabinet is made of galvanized sheet metal with electrostatic spraying on the surface to enhance corrosion resistance.
◆Pressure gauge monitors the safe pressure range of SF6 gas inside the tank.
3.Economy.
◆Maintenance-free
◆Highly reliable
◆Life expectancy up to 20years
4. Program flexibility
◆Multiple wire feeding methods, can realize left, right, up or forward wires.
◆Multiple combination methods, each unit can realize any combination between the
◆Insulated busbar, can realize the front and back of the cabinet or left and right of the cabinet.
◆Flexible design options.
◆Spring mechanism and permanent magnet mechanism optional configuration.
