Product Description

 

CTW Spring Operating Mechanism

 

CTW spring operating mechanism will be used in XG series SF6 full insulated compact switchgear and other indoor vacuum circuit breaker with equivalent

closing power and output rotation angle. Its performances can meet requirements of GB1984 AC High Voltage Circuit Breaker and the product's Technical Conditions;

CTW-S manual operating mechanism holds functions of manual energy-storage; manual closing/opening.

CTW-D motor operating mechanism functions including motor or manual energy-storage; electromagnet or manual closing/opening.

 

Working Condition

 

• Altitude: ≤2000m
• Ambient temperature: -25°C~+40°C
• Relative humidity: Monthly average≤90% (25ºC);Daily average≤95% 
• Vapor data: Monthly average≤1.8kPa; Daily average≤2.2kPa
• Wind speed: ≤35m/s
• No operating in such places as subject to explosives, inflammables, corrosives and severe vibration
