The design of vacuum arcing chamber and insulation support sheath pipe is compact, because the outlet line conduct pole is coated silicon rubber, it can be suitable for bad weather and pollution environment.
The type vacuum arcing chamber adopts wave shape porcelain case, copper and chrome contactor material, cup shape and longitudinal magnetic field structure.
The type vacuum arcing chamber is miniaturization product, adopts copper and chrome contactor material, cup shape and longitudinal magnetic field structure, glass insulation case, sealing type shield barrel in the plate.
Apply the vacuum arcing chamber, air insulation and includes electric spring operation mechanism so that the product arcing ability is strong, short open circuit times is many, no fire and explosion danger, convenient operation, it is the product of good performance, and strong usefulness.
