Short Circuiting Device For Underground Railway For 3rd Rail
|DSSB-RAIL-PEE-SCD 3rd RAIL|
- This short circuiter is provided with a frame of glass fiber-reinforced synthetic tubes that are partly loosely joined and carry contacts and contact mechanism.
- The contact to the running rail consists of an aluminium shell into which aluminium contact rings are set. There is electric contact to the running rail at the moment when the device is placed onto it.
- Devices suitable for short circuit currents up to 80 kA are provided with a current rail contact.
- On both models those parts to take up voltage are either covered to a vast extent, or they are far enough at a distance of parts the user is to operate.
