Product Description
CTH-VD Spring Operating Mechanism
 
CTH-VD spring operating mechanism is apply to 12kV high voltage ring main unit switchgear (AC metal enclosed switchgear). 
CTH-VD holds functions of motor or manual energy-storage, manual closing/opening, motor closing/opening, equipped with break-brake spring.
It has same function of recloser and has reliable mechanical interlock with isolation mechanism.High reliability, long life time, easy installation, strong adaptability.
It can take places of GIS circuit breaker mechanism. Its performances can meet following requirements:
GB/T11022-2011 Common specifications for high-voltage switchgear and controlgear standards
GB1984-2014 AC High Voltage Circuit Breaker
