           Product Description

          Model:ZW8-12
          Product Name: ZW8-12/630 outdoor HV vacuum breaker
          Product Description:

          Adapt to 10kV distribution lines, small and medium size substation to close load current and break short-circuit current. According to the users' need it can be installed with manual or electrical isolator. It can have functions of remote control in 100m distance, automatically operation power supply, automatically open and close swithes, as well as lightning-protection. It is actually a full-featured modular electrical apparatus. This product is a dry type with reasonable design, simple structure, complete functions, reliable operation, small volume and light weight. It can meet many requirements of distribution automation.(dropout current specification:20 kA, 16 kA, 12.5 kA)
