KYN61-40.5 armored movable metal closed switch device high voltage switch gear
KYN61-40.5 series Metal-clad withdrawable AC metal-enclosed switchgear cabinet is a new type of product recently designed and developed by Xi'an High Voltage Electrical Research Institute. The switchgear frame is a metal-clad type structure design, inside equipped with new full-insulating vacuum circuit breaker or sulfur hexafluoride circuit breaker. The switchgear body uses packaged structure, which improves appearance quality and manufacturing accuracy, and shortens the production cycle. The normal operation of switchgear conduct on the conditions of high pressure isolated room with door closed. The switchgear cabinet conforms to regulation of IEC-60298,GB3906,with sound "five-prevents" function.
2. Application:
KYN61-40.5 type switchgear cabinet is suitable for use in system of 40.5KV, three-phase AC 50HZ, as an indoor distribution equipment to accept and distribute power, with function of circuit control, circuit protection and circuit detection. In addition to be suitable for general power system, it also can be used in frequent operation places. It works in normal environment conditionsregulated in GB 3906-20063-35 kV AC metal armored shift switch cabinet.
