Product Details

Product description

Volcano main products include vacuum interrupter, embedded pole etc. electrical products. Vacuum interrupter is ceramics type, and the range of voltage is from 1.14kV to 40.5kV, current from 63A to 4000A, rated short circuit breaking current from 2kA to 40kA. Volcanoproducts are complied with relevant national standards and international standards (GB standards and IEC standards). After three large scale technical transformation, introducing advanced production processing equipment from Germany and United States, Volcano has the first-class technology equipment and perfect testing means, and products with the characteristic of standardization, seriation, miniaturization, specialization. For the meantime, Volcano has an experienced R&D team, and a complete , mature R&D program, a special department to organize the development of new products. In order to accurately grasp the development trend of industry technology , Volcano establishes a long-term good relation of cooperation with other well-known domestic and foreign institutions, and carry out technical exchanges with the international well-known enterprises to jointly develop the key products leading the market trend.

In mounting, attention should be paid to the following:

a. When operating, guide unite unit must be provided for the interrupter. The coaxality of moving conducting pole and axial line of interrupter must meet the requirement. There should not be torque force applied on the bellow.

b. When mounting, it is forbidden to beat or strike the interrupter envelop with hard things in case crack may occur to cause air leakage.

c. Take care to assure that the conducting pole must be coaxial with interrupter, and that the conducting pole must be vertical on the face of fixed end

d. Take care not to disassemble the interrupter repeatedly to prevent screw from slipping. There should not be twisting on the moving conducting pole and over press on bellow to avoid that any torque force and scratch may occur to bellow to reduce its service life.

e. During mounting, the force applied on the face of both ends should not go beyond the static relief pressure stipulated in the specification.
