Three position load switch structure design

 

Visible switch working position

 

Maintenance-free, suitability for outdoor application

 

Optional Spring operating mechanism, permanent magnetic controller

 

Standard modular design of manual and automatic operating mechanism, flexible assemble enabling

 

Arc-protection by separate phase to phase insulation

 

Comprehensive Modular Design, high standardized modular design enables flexible assembling and maintenance

 

Multiple interlock function, safe operation ensured

 

Equipped with power network automation terminal modular, suitable for enterprises power network updating and rebuilding

 

Operation Mechanism adopts three protection processes, suitable for sever ambient conditions of site

  

 

Benefits of Product Application

 

Suitability for application in areas with low temperatures

The design of solid ring main unit reduces the dependence on SF6 gas which eliminate the potential problem caused by insulation gas of being liquefied under low temperature

Suitability for application in areas with high temperatures

The increased pressure caused by higher temperature is no longer an issue for solid dielectric ring main unit

 

Suitability for application in low-lying areas and construction sites with labor forces

The density of SF6 is five times more than normal air under the same condition, leaked SF6 are easily deposited in low-lying areas which is very dangerous for people working there. People can be suffocated by leaked gas.

Suitability for application in closed environment:

Vacuum arc extinguishing chamber is under normal pressure where all bushing and sealed fillings are solid dielectric which prevent the potential of explosion caused by normal gas insulated product.

 

Suitability for frequent switching operation

SF6 load switch is designed for switch operations for up to 2000 times, while the switch operations for solid dielectric designed ring main units are more than 100000 times.

Suitability for environmental protection

The green house effect caused by SF6 has drawn much attention, solid dielectric designed ring main unit eliminate the use of SF6 gas, which further meet the national requirement for environmental protection.
