CTB Spring Load Drive Operating Mechanism VCB
Model CTB spring operating mechanism is mainly used in the outdoor Model ZW32 pole-mounted vacuum circuit breaker with a rated voltage 12kv and other indoor and outdoor vacuum circuit breaker and load switches with similar closing power. It is used on the side-mounted switchgear to decrease the depth of the switchgear.
Product features:
1.It features compact, small volume and a longitudinal direct-acting driven arrangement to decrease the size of the switchgear effectively.
2.Both manual and motor driven charged operations are available and it is convenience to local or remote operation by the final user .
3.The key parts are subjected to the nitrogenation treatment and they are durable and have high impact strength.The component surface adopt composite zinc plating and the long-term low temperature grease is applied so that the product is able to meet different weather conditions.
4.Both AC and DC power operation are available and it is convenience for the users without DC power supply.
Working conditions:
1. The upper limit of ambient air temperature is +40ºC and the lower limit is -45ºC.
2. The altitude does not exceed 2000m. The wind speed does not exceed 35m/s.
3. The daily average relative humidity is not more than 95%, and the monthly average is not more than 90% (+25ºC).
The daily average water vapor pressure is not more than 2.2×103MPa, and the monthly average is not more than 1.8×103MPa.
4. There is no fire, explosion hazard, serious dirt, corrosion and severe vibration.
