electrical power distribution equipment for solid inflatable switchgear

Product Overview

Description

1. Description

 SRM-16/12 insulated switchgear mainly has three functional unit modules, namely D unit (breaker unit), I unit (load switch unit), and R unit(fuse combination electrical unit). The main switch of each unit is a vacuumswitch.When the distribution network system requires the combination ofmultiple units, it can be arbitrarily expanded according to the distribution network requirements. Arbitrarily arrange according to different design schemes to achieve different distribution network requirements.
