The CS-2 hand-crank operating mechanism provides manual opening and closing of outdoor high-voltage disconnect switches on electrified railway catenary and in substations. The crank gearing keeps operating force low, and the locking device holds the switch securely in either end position.
The mechanism suits outdoor traction power environments from -40°C to +70°C at altitudes up to 4,000 m, with a hot-dip galvanized steel housing for long service life.
It is matched to the GW1/GW4 disconnect switch families and mounts on pole-side brackets or independent foundations together with the switch.
Henan Chuangwei Railway Equipment Co., Ltd. supplies the CS-2 with new switches or as a replacement mechanism for existing installations.
Frequently Asked Questions
What is the advantage of a hand-crank mechanism?
The crank gearing reduces the manual force needed to operate the switch, and the built-in locking device secures the blade in the open or closed position.
Which switches does the CS-2 fit?
Our GW1/GW4 outdoor disconnect switch families; ask us to confirm compatibility with third-party models.
Is it suitable for outdoor substations?
Yes — the galvanized housing and sealed details are designed for long-term outdoor service.
