Product overview

HXGN囗-12 box-type fixed metal-enclosed switchgear (referred to as ring network cabinet), AC high-voltage complete set of equipment with rated voltage 12kV and rated frequency 50Hz, mainly used for three-phase AC ring network, terminal distribution network and industrial use Electrical equipment, which plays the role of receiving, distributing electric energy and protecting. It is also suitable for installation in box-type substations. This product complies with GB3906 "3~35kV AC metal-enclosed switchgear", GB/T11022 "Shared technical requirements for high-voltage switchgear and control equipment standards", IEC60298 "AC metal-enclosed switchgear and control equipment with rated voltage above 1KV and 52KV and below" : Requirements of the IEC60694 "Common Clauses for High Voltage Switchgear and Control Equipment" standard. And has the "five prevention" interlocking function.
