10kV MV Rotary Indoor Isolating Switch with Earthing Device, VACG30-12(D)

1. General description

VACG30-12 indoor AC M.V. rotary disconnecting switch is a new type of switch added rotary knife, the main structure is in tri-phase chassis, two planes, fixed two sets of insulator and contact, through the rotary knife, so as to realize the switch closing and opening.

The VACG30-12D isolating switch is in the VACG30-12 switch based on the increased with a grounding knife type, can meet the needs of different power systems, its performance conforms to GB1985-2004 AC M.V. Disconnecting Switch and Earthing Switch, used to connect and transfer line voltage without load, it is applied in power system of indoor 12kV and tri-phase AC 50Hz, rated current of 400,630,1000,1250A. And supporting the use of M.V. switchgear also can be used separately.

The Technical Specifications of this disconnecting switch define its electrical and mechanical parameters for indoor medium-voltage distribution applications. The isolating switch model VACG30-12(D) is a new type of rotary disconnecting switch with an added earthing device, featuring a tri-phase chassis design with two planes and two sets of insulators and contacts that operate through a rotary knife mechanism to realize switch closing and opening. This mv disconnecting switch is designed for indoor 12kV three-phase AC 50Hz power systems with rated currents of 400A, 630A, 1000A, and 1250A, used to connect and transfer line voltage without load. The disconnecting switch VACG30-12D is based on the VACG30-12 switch with an added grounding knife type, meeting different power system requirements. This isolating switch complies with GB1985-2004 AC M.V. Disconnecting Switch and Earthing Switch standards. The mv disconnecting switch offers rated short-time withstand currents of 12.5kA, 20kA, and 31.5kA, with rated peak withstand currents of 31.5kA, 50kA, and 80kA. Each disconnecting switch can be used in conjunction with medium-voltage switchgear or independently. Proper installation of this isolating switch ensures safe and reliable line isolation and earthing in 12kV distribution networks.
