Product Overview
This switchgear is a high-quality air-insulated switchgear that has been fully type-tested.It is designed for 12 kV,three-phase AC 50 Hz power systems,and is widely used in power plants,substations,industrial,mining enterprises,railway transportation and high-rise buildings for power distribution,as well as circuit control,protection and monitoring.
The enclosure is assembled from aluminum-zinc coated steel plates and galvanized steel plates,ensuring high mechanical precision between the withdrawable unit and the switchgear.The withdrawable unit can be easily moved in and out and features excellent interchangeability.
The product features compact design,complete solutions,and safe and reliable operation.

Compliance with Standards
The product is designed and manufactured in accordance with IEC 62271-200,GB/T 3906 and DL/T 404 standards.
Product Features
The switchgear adopts a metal-clad metal-enclosed design,consisting of a cubicle and a withdrawable circuit breaker unit.
The cubicle is divided into four independent compartments:circuit breaker compartment,busbar compartment,cable compartment and low-voltage compartment.
Each compartment is equipped with a pressure relief duct and vent opening.In the event of an internal arc fault,the top-mounted pressure relief flap automatically opens to release internal pressure,ensuring the safety of personnel and equipment.
The switchgear supports overhead line or cable incoming and outgoing connections,allowing flexible system configurations to meet different distribution requirements.A reliable five-interlocking system is incorporated to prevent incorrect operation.
