Earthing kits for railway contact lines, power lines and transformers and earthing sticks, 36.5 kA
Country: Germany · Model: Rail earthing kits
Railway earthing and short-circuiting kits for contact lines, power supply lines and pole-mounted transformers withstand a short-circuit current of 36.5 kA for 0.12 s. They are made per IEC 61230 taking into account the specifics of track infrastructure and traction power supply. The programme also includes railway earthing sticks with red and white signal colouring.

Description
The kit for the contact line is made for a contact wire height from 4.8 to 6.25 m. Its two-section telescopic stick is continuously adjustable to the required working height, and from a transport length of 2.6 m it extends to 5 m. The device consists of an earth cable with a cross-section of 50 mm², a P51D contact wire clamp and an R50 rail clamp fixed to the rail foot. The version without track possession is additionally supplied with a suspension hook and signal flags. For mobile use there is a "car" kit with a five-section plug-in stick with a transport length of 1.1 m and two earthing devices. The stick and the ratchet of the rail clamp in it can be removed to fence off the work site.
How to choose
The kit is chosen by the site. For railway power supply lines a set with a two-section telescopic stick of 1.8/3.5 m, a 50 mm² cable 4 m long, a P50D clamp with a probe and a U2 earthing clamp is used. Pole-mounted transformers are earthed with the same stick and two devices with a P4D line clamp and a U2 clamp. For protective earthing of construction machines there is a device with a 50 mm² cable 12 m long, a U2 clamp and an R50 rail clamp. Single-pole cables, rail and earthing clamps, contact wire clamps, bags and wall holders are supplied separately.

FAQ
How does the 12 m cable differ from the 8.5 m cable in the contact line kit?
The 12 m cable makes it possible to earth the contact line without track possession, and the 8.5 m cable is used for work with track possession.
Does the R50 rail clamp allow rolling stock to pass?
Yes, the R50 clamp fixed to the rail foot allows rolling stock that does not use traction power to pass.
What lengths do railway earthing sticks have?
Two-section telescopic sticks with a roller lock or an aluminium head are 3.5 and 5 m long, three-section ones 4.5, 5.08 and 7 m. The five-section plug-in stick is 4.9 m long with a transport length of 1.1 m.
Can the kit be used after a short-circuit current has acted on it?
No, like network devices per IEC 61230, the kit is not used again after a short-circuit current. The withstand of all kits is 36.5 kA for 0.12 s.
What are the railway earthing sticks made of?
The sticks are made of fibreglass tube with red and white signal colouring, which marks the work site. Some versions carry designations per the DB Ebgw standards.
