Product Description
GN25-12 Series indoor AC high voltage isolation switch
1. Product Description
GN25-12(GN25-12C)Series indoor AC high-voltage isolation switch is a three-phase AC 50Hz high voltage switchgear for rated voltage of 10KV power system, as in the case of no load voltage points, closing the circuit. Isolation switch is equipped with CS6-1 type manual actuator.
2. Structure Introduction
Three-phase isolation switch blade structure, the undercarriage, the knife, static contact, insulated rod, post insulators and other components.
GN25-12 paperback form structure, GN25-12C to form through the wall structure.
The product that is different from the traditional structure of the product, in order to solve the contradiction between the contact pressure and operating torque, using the closing - lock-step operation principle, so as to meet the requirements under the premise of high current switching contact pressure, with less operating torque; the entire switch structure is simple, convenient debugging, reliable locking mechanism; knife switch contacts have some early pressure, and thus have a certain self-cleaning ability; touch-line tool designed to increase the magnetic lock slot board structure and improve the mechanical and electrical switch performance.
