Sm6 Sf6 Insulated Switchgear

We are engaged in manufacturing, exporting and supplying excellent quality SM6 SF6 Insulated Switchgear to our valuable clients.

1. General Description:
A new generation type SF6 load switch which is installed with epoxy resin enclosure inside and uses SF6 for insulation. It can work in a voltage range maximum up to 24KV.

2. Technical Features:
Using SF6 gas for insulation
The inside of the switch enclosure is full of SF6 GAS, which is non-toxic, colorless and odorless, nonflammable, inert, heveier than air and with electronegativity and really high quality insulating material.

3. SF6 gas pressure inside of switch enclosure:
Inflation pressure (gauge pressure): 0.042~0.045Mpa
Maximum pressure: 0.048Mpa
Design temperature: 80C
Action pressure of structure vulnerable point: >=0.08Mpa
Annual leakage rate of SF6 gas <=0.1% year

4. Load switch and earthing switch through interlocking device and stored-energy spring to comprise the operating mechanism

5. Logic mechanical interlocking to prevent faulty operation

6. Safety: All high voltage parts which including cable terminal connector and busbar are installed inside of enclosure.

7. Standard:
