Product features
Operation safety:
We can provide users with special security through the following security measures:
Integrated three-station load switch
Circuit breaker adopts load switch instead of isolation switch, which is more safe and reliable ，The fully sealed design on the primary side provides protection against accidental contact, mechanical interlocking that meets the requirements of five-proof, and the live display can provide access to the line, and the live indication is reliable; Full airtight design, all 10kV switches and bus electrified bodies are sealed in 3mm stainless steel welded air box; It is equipped with a silicone rubber cable plug to achieve full insulation
and sealing of the cable head, so the spring energy storage operation mechanism will not be affected by the external environment such as ash layer, moisture, small animals, etc. The panel can be operated manually or electrically. The analog line diagram provides the switch position, and the indication cabinet is made of galvanized plate. The surface is electrostatically sprayed to enhance the anti-corrosion performance. The pressure gauge monitors the safe pressure range of SF6 gas in the box.
Economical:
Maintenance-free, highly reliable and service life up to 20 years
