Product Specifications
--Product Description
1. Description
FTG-12 solid 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 vacuum
switch.When the distribution network system requires the combination of
multiple 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.
