Copper-bonded earthing rods 14.2–18.2 mm and clamps TGT / GTR / TRP / PTR
Country: Spain · Model: TGT / GTR / TRP / PTR
Copper-bonded earthing rods of 14.2, 14.6 and 18.2 mm diameter and 1.5 or 2.0 m length, together with the clamps TGT, GTR, TRP and PTR, form the earthing system of substations, poles and buildings. The steel core withstands driving into the ground, and the 100 or 300 µm copper coating protects against corrosion.

Description
The rods are made of calibrated steel with an electrolytic copper coating. The sizes 14.2 mm × 1.5 and 2.0 m and 18.2 mm × 2.0 m have a 100 µm coating, and 14.6 mm × 2.0 m has 300 µm. They comply with UNE-EN IEC 62561-1:2023 and UNE 202006 and are AENOR certified. The conductor is fixed to the rod with brass clamps: TGT142 with a galvanized steel yoke for 14.2 and 14.6 mm rods, the reinforced TGT142 RF, the closed TGT142C, TGT142C-A2 for 18.6 mm and GTR with stainless screws. The parallel clamp TRP is intended for overhead line conductors. Tinned copper parts with 15 µm tinning, GDC for wall mounting, CDCC-50 for crossing 50 mm² cables and TMV-8 for an 8 mm copper rod with an M8×35 screw, are installed inside substations. The PTR polyester link is a disconnectable point for measuring earth resistance and accepts cable up to 70 mm². For branches there are also the crimped CRC and the screw-type TR/TRT.
How to choose
The rod size is chosen by the soil and the length of the loop. Copper of 100 µm is on the 14.2 and 18.2 mm rods, while the 14.6 mm rod with a 300 µm coating gives a thicker copper layer. The clamp is selected by rod diameter, TGT142 for 14.2 and 14.6 mm. Loop branches are made with CRC or TR/TRT, while GDC, CDCC-50 and TMV-8 remain for loops inside substations.

FAQ
What diameters and lengths do the copper-bonded rods have?
14.2 mm in lengths of 1.5 and 2.0 m, 18.2 mm in a length of 2.0 m, and 14.6 mm in a length of 2.0 m.
What is the thickness of the copper coating on the rods?
100 µm for the 14.2 and 18.2 mm rods and 300 µm for the 14.6 mm one. The steel core gives strength when driving.
Which standards do the rods comply with?
UNE-EN IEC 62561-1:2023 and UNE 202006, with AENOR certification.
What is the PTR link for?
It is a disconnectable point for measuring earth resistance, and it accepts cable of up to 70 mm² cross-section.
Which clamps suit a 14.2 mm rod?
TGT142 with a galvanized steel yoke, the reinforced TGT142 RF, the closed TGT142C and GTR with stainless screws.
