• CT118 Spring Operating Mechanism Product Overview

  Model CT118 spring operating mechanism is used to operate 72.5kv, 126kv and 145kv circuit breaker (GCB) and the fully-enclosed composition electrical apparatus (GIS). Also it can be used to close and open other outdoor and indoor circuit breaker of the similar closing and opening energy.

  Technical Features:

  1.If compared with the hydraulic mechanism, the spring charged operating mechanism features a simple structure, reliable performance and low maintenance cost.
  2.The high strength aluminum alloy frame and the integral structure feature a high rigidity, which is shaped by N/C machining center with high precision.
  3.The components adopt high quality alloy steel and by the advanced heat treatment, the components feature a high strength, high toughness, goog reliability , stable mechanical performance and long mechanical endurance.
  4.The structure of the operating mechanism is clear and distinct so that it is convenience in the installation and maintenance.

  Condition of Service:
  1.Place of Service: indoor and outdoor;
  2.Ambient Air Temperature: max. +40℃, min. -40℃;
  3.Relative Humidity: daily averaged RH ≯ 95%, monthly averaged RH ≯ 90% (25℃);
  4.Vapor Pressure: daily averaged ≯ 2.2 x 10-3 MPa; monthly averaged ≯ 1.8 x 10-3 MPa;
  5.Air Contamination: Class III;
  6.Earthquake Intensity: Degree 9
  7.Neither serious corrosion nor frequent tense vibration is existed.
