VFC- 7.2/12kv Indoor High Vacuum contactor-Fuse Combinations
VFC middle-placed vacuum Contactor-fuse combinations is used to open a wide range of short circuit fault current of high voltage fuse and frequence operation of vacuum contact and intergrated relay protection devise. VFC product can be assembled on 650mm or 800mm wide type of switchgear, the cabinet of size and assembly are competely consistent with ABB completely interchangeable.
VFC uses modular design of epoxy resin for separated solid technology, design operating conditions are in accordance with level II pollution level 20mm/kv creepage distance requirements. Core component and a main circuit conductor use APG epoxy resin (automatic pressure gel injection) process of solid insulation, thus comletely eliminate the past products.
VFC vacuum contact-fuse combinations is handcart type.is adapts to current mainstream of the structure os the switch, can be reqplced high voltage fuse when the handcarte puts out.
Embedded poles used a infinite reliable imported Germany Siemens interrupter, it has stable performance and reliable in quality
