Brief Description
GW16B/17B Series of disconnectors are improved by us on the basis of Series GW16/17 disconnectors. Besides the traditional virtues of single-arm folding style, this new-type products adopt the hot-galvanizing process on surfaces of exposed ferrous metal components and double-seal rolling contact finger. By means of the above modification, GW16B/17B Series of disconnectors will hold the dominant position in the disconnector market.
Main Features
1 Reasonable new structure, reliable performance and service;
2 Excellent mechanical properties, small operating force, long mechanical endurance;
3 Moving contact is single-arm folding style, the driving components are sealed in the conducting rod with no influence of bad weather;
4 Improve anticorrosive, waterproof, dustproof, anti-freezing capability and mechanical stability, etc., remove the defects such as contact heating and big opening impulse to make the performance more reliable.
