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
Applying ambient conditions
1. Ambient temperature:-15~+40ºC.
2. The height above sea level:≤1000m(besides the special
requirements).
3. Relative humidity:the average humidity of a day should be no
more than 95%;the average humidity of a month should be no more
than 90%.
4. Saturated vapor pressure:the average pressure of a day should be
no more than 2.2kPa:the average pressure of a month should be no
more than 1.8kPa.
5. Earthquake intensity:not exceed 8 degrees.
6. It should be installed in the places without
fire,explosion,serious filth, chemical erosion and violent
vibration.
