LBS(PGS)-12,24,36KV SF6 Insulated Load Break Switch Vacuum Circuit Breaker

 
LBS(PGS) pole mounted load break switch is used for breaking rated voltage 12/24/36kV,rated current 630A,1250A,50/60Hz power distribution system,closing load current and over load current of power system,it could separate automatically track sections of power distribution which faults occur.The switch is matched with electronic controller which is with the latest technology. The switch has manual,motor,remote operation modes.The electronic controller would be installed inside the stainless steel box, so i could be used in various climate conditions.Besides that,the wire/wireless modem installed inside control box could achieve remote monitoring and controlling.It's easy and convenient for instllation the switch on pole,and that could reduce the execution cost.
 
Availability:
Quantity:

1.SF6 gas-insulated:SF6 gas is a kind of nontoxic,nonflammable and electrical insulating gas.It has the excellent characteristic of arc extinction.

2.Drivepipe with large diversity:In addition to standard ceramic bushing,we can also provide a variety of programs,including rubber insulators in an epoxy bushing device.

3. Visible open /closed status:It is easy to see the main contact position indicator which is color-coded just standing on the ground (Green-off;red-closed).The indicator is directly connected with the main contacts of the drive shaft assembly to ensure accurate display of contact states.

4. Quick operation:Operating mechanism with spring energy to ensure a quick closing and opening operation (less than 100 miliseconds).

5.Can realize remote control:it is equipped with electronic controler,fit for in situ operation as well as FTU interface console operation.

6. Rugged switch:The switch is made of proven durable,corrosion-resistant materials (special used in warships 304L stainless steel plate)which ensures that there is a very long service life(30 years),and can be implement a series of operations.It has the ideal characteristics as a column equipment.

7.Standard:Each switch before leaving the factory has been flled with SF gas,sealed,and test according to IEC60265-1(1988),

GB40.504-1990 standard.
