Protect and control the electric equipments for power supply and transformer substations.
Especially suitable for ring main unit,distribution switching substation and cable distribution cabinet .
Natural interlock system is easy and reliable, preventing wrong operation & ensures personal safety.
Even when the cable compartment door is open,the interlocking also functions .
The pressure relief valve is located at the rear of the gas tank. It relieves interior pressure when SF6 gas is overpressure resulted from an arc fault. 



3. Structure
The enclosure is a perfect sealing system,at the rear of this gas tank, there is a valve for pressure relief when the arc fault leads to the overpressure of SF6 gas.
We supply:
1).The whole switchgear
2) SF6 load break switch top unit
2).12kv,24kv indoor sf6 load break switch (phase distance:210mm, 275mm )
3).36kv indoor sf6 load break switch 
5). Load break switch + fuse combination lower unit
3.  Operation mechanism 
Using spring operating mechanisms:
There are single spring and double spring -2 types of mechanisms for your choice.
Both types could become motorized by mounting a motor part.
