Basic Info
Model No.: VS1-12
Product Description
Model NO.: VS1-12 Operation: Electric Type Arc-extinguishing Medium: Vacuum Poles Number: 3 Function: Overcurrent Protection Opertion Model: Electrically or Manually Origin: Jiangyin Yunfeng, China Breaking Capacity: High Voltage Circuit Breakers Speed: High-Speed Circuit breaker Installation: Fixed Type: Circuit Breaker Certification: ISO9001-2000, CE Trademark: YF Product Overview
VS1(VYF1-12)series indoor AC HV Vacuum Circuit Breaker is applied in 50 Hz network with the rated voltage of 12kV and it is the product developed and manufactured by our company through bringing in ABB's technology and in combination with domestic industrial development conditions and manufacturing capacity. The overall structure of such product is the form of integrative installation of switch body and Operation Mechanism. The composite insulation structure is used for the product. It has no pollution, no explosive hazards and high insulation level. It can be used at the site such as mining and industrial enterprises, power generation plants and substations, etc. for controlling and protecting the equipment. It is particulary applicable for the industry required for frequent operation, such as electric arc steel-making of matallurgy.
The integrated design of modularized spring operation mechanism and circuit breaker body can be used for the operation mechanism of the series product. It not only can be used as the fixed installation unit, but also can compose the handcart unit for using. It not only can be operated electrically, but also can be operated manually.
