FLN36-12 Indoor load break switch (LBS) 12KV

FLN36-12 type indoor high voltage AC load breaker switch refer to international new technology and develop the switching equipment in according to the relevant standards in China's electric power system. Its performance indicators in full compliance IEC420, 694,129 and national standards GB3804-2004.

This is the main switching element RMU. The load breaker switch is a multifunctional medium voltage switchgear of gates, sub-gate, earthing. In a fully sealed with strengthen the structure of the epoxy resin housing to filled with SF6 gas,0.05MPa, with the minimum parts to achieve the above three functions, to ensure product quality, improve reliability, maintenance-free. It can be safely run for more than 20 years in normal conditions.
