1. Operational safety. Through the following security measures, we can provide users with special security guarantees: 

▽ Integrated three-station load switch 

▽ Circuit breaker adopts load switch instead of isolation switch, which is more safe and reliable 

▽ One-side fully enclosed design provides protection against accidental contact 

▽ Mechanical interlock to meet the requirements of five defenses 

▽ Electricity display can provide instructions for electrification on the incoming and outgoing lines 

2. reliable operation. Fully sealed design, all 10kV switch and busbar charged body are sealed in the air box welded with 3mm stainless steel plate; equipped with silicone rubber cable plug to realize the cable head Edge sealed so that it is not affected by dust, moisture, small animals and other external environment: 

▽ Spring energy storage operating mechanism, can be manually or electrically operated 

▽ Panel model line diagram provides switch position indication 

▽ Cabinet made of galvanized sheet, electrostatic spraying on the surface to enhance corrosion resistance 

▽ The pressure gauge monitors the safe pressure range of SF6 gas in the box 

3. Economicality. 

▽ Maintenance-free 

▽ highly reliable 

▽ Service life up to 20 years 

4. The program is flexible. 

▽ A variety of ways to enter, can achieve left, right, up or forward line 

▽ multiple combinations, any combination between the units can be achieved 

▽ Insulation busbars can be used to combine front and back cabinets or cabinets 

▽ Flexible design 

▽ Optional arrangement of spring mechanism and permanent magnet mechanism
