PATF / ERLAIN / PATC-BP earthing sets for railway and tram contact lines and potential transfer kits for overhead lines
Country: Spain · Model: PATF / ERLAIN / PATC-BP
PATF single-pole portable earths are applied to a contact wire of Ø 12–27 mm or up to Ø 35 mm and connected to the rail with a 50 mm² copper cable 7 m long. The group also includes the ERLAIN kit, with which one worker earths an overhead line, and the PATC-BP for transferring the earthing point at height, all made to IEC 61230. They are ordered by contact line services of railways, trams and metro and by crews repairing 6–35 kV overhead lines and high-voltage lines.

Description
The PDC clamp of aluminium alloy has screw tightening and a bayonet shank, and is placed on single and double contact suspension and on a rigid contact wire. The PATF is connected to the rail with a TTR or TTRS clamp, and the kit is stored in a nylon bag. The ERLAIN is assembled from three telescopic metal sticks of three sections each with self-locking fixed clamps for wires of Ø 3–22 mm, a reel with three 35 mm² copper cables of 10 m each, two galvanised hexagonal earth rods of 1 m each, a holder and a bag. Its insulating stick is made of epoxy fibreglass, filled with polyurethane foam and certified to IEC 60855. The reel is tightened with a torque of not more than 15 N·m. In the PATC-BP the intermediate BPGA clamp is fixed on an aluminium tube 3 m long.
How to choose
The kit type is determined by the place of work. On a contact suspension and a rigid wire the PATF-PDC works, on wires up to 35 mm the PATF-PC, and in metro and underground tram tunnels the PATF-PC-TTIR and PATF-PDC-TTIR versions with a TTIR clamp. The ERLAIN has no voltage detector, so absence of voltage on the overhead line is checked with a separate instrument, for example a VTE for 5–35 or 5–66 kV. For 0.4 kV networks it is simpler to take the ELBT-PAT/CC with four PEBT clamps for wires of Ø 3–18 mm, and for work at 132 kV there is the BSC-132/BP stick per EN 50508, 3 m long.

FAQ
What sections does the ERLAIN insulating stick consist of?
The 5 m stick has three sections of 1.72, 1.65 and 1.63 m. Without the middle section its length is 3.4 m.
What cable and clamp does the PATC-BP kit have?
The PA40/BP clamp grips conductors of Ø 10–60 mm and is connected with a 120 mm² copper cable 6 m long.
What is used to check absence of voltage on a 25 kV contact line before applying PATF?
The VTE-25-U detector is intended for 25 kV high-speed railway networks. The PATF includes only a clamp, a cable, a rail clamp and a bag, so the detector is ordered separately.
Can one worker earth an overhead line with the ERLAIN kit?
Yes, the ERLAIN is assembled precisely for one-person work. The three telescopic sticks with self-locking clamps are hung on the phases, and the reel connects them with the earth rods.
