Product Overview

Description

JCZ5-7.2(12) grid-connected power substation vacuum contactor

 

JCZ5-7.2(12) indoor high voltage vacuum circuit breaker is a type of 12kv,50HZ three phase alternating switch. The mechanism and vacuum interrupter are designed to be a whole. Specialized 3AF type spring operating structure from Siemens can be operated by manual or carry out direct current energy saving operation. It’s can be designed as 210mm,230mm,250mm,275mm and other kinds of phase space, which matches better with different kinds of switchgear, such as handcart type JYN2-12,JYN6-12,KYN2-12.      

 

Ambient condition

1 Ambient temperature: max +40°C min -15°C(conveyance under -30°C is allowed)

2 Altitude: ≤1000m

3 Relative humidity: daily average relative humidity: ≤95%; monthly average relative humidity≤90%; daily average saturated vapor pressure ≤2.2*10-3 MPa; monthly average value   ≤1.8*10-3 MPa

4 Earthquake intensity: ≤8 degree

5 The installation should be free from fire, explosion, severe vibration, chemical corrosion and serious pollution
