RLW type Solid dielectric load break switch


RLW type load break switch is a solid dielectric type with silicone rubber coating outdoor switchgear, which is adopt vacuum interrupting technology, equipped with a spring mechanism.

RLW type load break switch is compact design, very light and easy for pole mounted.

RLW is long mechnical & Electrical design life LBS, It is reliable at 10,000 times operation life.

RLW current rating up to 1250A maximum, 20kA.

RLW type offer the voltage rating : 12kV, 24kV, 36kV

RLW type LBS is also capable to expanding to different functions:

----------------------------------------------------------

Simple function using RLW basic type manual LBS.

Simple function RLW basic type motorized LBS.

----------------------------------------------------------

Multi-function RLW type motorized LBS with CT/PT combination switchgear which can ahieve remote control with normal switching on/off and measuring function.

----------------------------------------------------------

Multi-function RLW type motorized LBS with CT/PT combination switchgear which can ahieve remote control with special sectionalizer functiion.
