electric supplies box power distribution non-low voltage switchgear
1.Product Description
Ac metal closed type shift switch cabinet is a three-phase ac 50HZ
indoor device metal closed switch equipment.Is used in power
plants, substation system rated voltage 35kV, rated maximum current
2000A maximum voltage no more than 40.5kV single bus or single bus
sectionalized sets of distribution equipment.
This switch device meets the requirements of DL/ t404-91, IEC298,
GB3906 and other standards, and has the functions of preventing
wrong operation of circuit breaker, pushing and pulling handcart
with load, grounding line, power transmission with grounding line
and accidental charging interval (referred to as "five
precautions")
