The CJ-2 electric operating mechanism motorizes the opening and closing of 27.5kV high-voltage disconnectors used on electrified railway catenary and in traction substations. It enables remote control, making it the standard choice for automation retrofits and SCADA-integrated installations.
The mechanism is designed for outdoor traction power environments from -40°C to +70°C at altitudes up to 4,000 m, with a hot-dip galvanized steel housing and robust drive train matched to the GW1/GW4 switch families.
It mounts with the switch on pole-side brackets or independent foundations and can be combined with position indication and interlocking accessories for safe automated operation.
Henan Chuangwit Railway Equipment Co., Ltd. supplies the CJ-2 together with its disconnectors or as a retrofit kit for existing installations.
Frequently Asked Questions
Which disconnectors does the CJ-2 fit?
It is matched to our 27.5kV GW1/GW4 disconnector families; for third-party switches, contact us with the switch model to confirm compatibility.
Does it support remote control?
Yes — the CJ-2 supports remote open/close control and is suitable for SCADA integration and automation retrofits.
Can it be retrofitted to existing manual switches?
In many cases yes, as a retrofit kit. Share your site photos and switch model for an engineering assessment.
