Product Description

FTG-12 solid insulated switchgear mainly has three functional units, namely D unit (breaker unit), I unit (Load switch unit), R unit (combined electrical unit).
Each unit is structurally divided into three parts: an instrument room, an operating mechanism, and a primary circuit.
Instrument room with microcomputer protection (intelligent controller) and other meters;
The operating mechanism is a special bomb operating mechanism, or with electric operating mechanism.
The primary circuit adopts the APG automatic gel process to connect the busbar, the isolating switch and the extinguishing arc chamber is completely sealed in epoxy resin and has a special connector and busbar connection.
Application places:
Widely used in industrial-grade civil ring and terminal power supply. Especially suitable for small secondary power stations, opening and closing stations, industrial and mining enterprises, airports, railways, commercial areas, high-rise buildings, highways, subways, tunnels, etc.
