12kV Pneumatic Type LBS-Fuse Composite Apparatus
1. It combines LBS, earthing switch and fuse on one frame. It is compact and with small volume, easy to installation.
2. Direct-acting isolating fracture, high dynamic and thermal stable current; it can be operated at one time due to unique linkage operating procedures.
3. With insulation cover of fixed contact, it isolates ring main unit on structure, saves isolation plate between phases and gaps, can preventing arc short circuit in switchgear
4. With unique shutter structure, when LBS opening, earthing switch closed and shutter closed, with good protective performance.
5. Load break switch, earthing switch and fuse are in accordance with "5 prevention" mechanical interlock, which can prevent misoperation and is safe and reliable.
6. Charged energy by spring operating mechanism, can closing and opening by electrical and by manual.
12kV Pneumatic Type Load Break Switch
1.With earthing switch, the switch can withstand making short circuit current.
2.The operating mechanism can be operated by electrical or manual, which is easy to realize remote control.
3.Ambient temperature: -25ºC~+40ºC
4.The height above sea level≤1000m.
5.Relative humidity: the average humidity of a day should be no more than 95%; the average humidity of a month should be no more than 90%.
12kV Vacuum LBS-Fuse Composite Apparatus
1. The product uses vacuum interrupter. Its performance is stable and reliable, with long electrical life, high breaking capability, strong making/breaking ability and easy to be operation and maintenance.
2. It combines switch body and operating mechanism, which integrates disconnector, load break switch and earthing switch. It is compact and with small volume.
3. Tandem arrangement of direct-acting isolating fracture and vacuum interrupter, high dynamic and thermal stable current; it can be operated at one time due to unique linkage operating procedures.
4. Structure of cone fixed contact, insulation cover and shutter can separate busbar and load break switch unit completely.
5. Vacuum load break switch, earthing switch, shutter, switchgear door are in accordance with “5 prevention” mechanical interlock, which can prevent misoperation and is safe and reliable.
6. Charged energy by spring operating mechanism, can closing and opening by electrical and by manual.
12kV Pole-mounted SF6 Load Break Switch
1.SF6 is an insulation gas with excellent arc extinguishing performance;
2.Visible On/ OFF status, there are indicators on the operation side and the bottom of the device, it can be easily observed standing on the ground;
3.Durable, the switch shell is made of corrosion resistant material (304 stainless steel plate) and sprayed with protective paint to ensure a long service life (more than 30 years);
4.The main switch use fully sealed structure, not affected by the external environment;
5.Low leakage rate, less than 0.1%/year;.webp)
12kv Load Break Switch for RMU
1. It is a load switch for 12KV SF6 gas insulated switchgear.
2. The switches are mainly rotary dynamic contacts and use arc extinguishing grids to extinguish the arc, which have reliable performance and good insulation.
3. This series includes two-position and three-position switches.
4.Installation location: inside the box.
5.Ambient temperature (ºC): -45~+140.
