LB / PGC / TPA / CRC / TR / APC branch, bolted, crimped and screw clamps
Country: Spain · Model: LB / PGC / TPA / CRC / TR / APC
The bolted, crimped and screw clamps LB, PGC, TPA, CRC, TR and APC make branch connections and joints of conductors on 0.4 kV overhead lines, in panels and in earthing loops. The bodies are made of cast aluminium, copper or brass depending on the type.

Description
The bolted LB, made of cast aluminium with stainless screws, are used for quick branches on aluminium lines. The tinned PGC/B and LBE-ID with 20 µm of tin join aluminium and copper wires, and PGC/A branches aluminium overhead lines. TPA and TPA/D, made of aluminium alloy with 20 µm tinning and M12 screws, fix a conductor to metal structures and poles. The crimped CRA are made of aluminium alloy with a purity of at least 99.5 %, CRS is for Al–Al and Al–Cu (for Al–Cu the smaller cross-section must be the copper conductor), and CRC, made of electrolytic copper, is for Cu–Cu in earthing per EN 62561-1. Dies CDC5 and CD13 for hydraulic presses are available for them. The brass screw clamps TR (straight entry), TRE (90° entry), TRM (branch) and TRT (T-shaped) have galvanized screws and brackets, TRF is bimetallic and tinned for panels, and BEB on a bakelite base are more heat-resistant. The nut-type clamps APC, made of copper-plated brass, and the bimetallic APB for 25–120 mm² have a conductor separator.
How to choose
The type is set by the conductor materials. Aluminium to aluminium is covered by LB or CRA, aluminium to copper by PGC/B, LBE-ID, CRS or APB, and copper to copper by CRC or TR. Crimped clamps require a hydraulic press with CDC5 or CD13 dies, while bolted and screw ones are tightened with screws.

FAQ
What are the CRC clamps for and to which standard?
CRC, made of electrolytic copper for Cu–Cu connections, mainly in earthing loops, complies with EN 62561-1.
Which clamp is needed for an Al–Cu branch?
CRS allows Al–Cu, and the conductor of the smaller cross-section must be the copper one. Among bolted types, the tinned PGC/B and LBE-ID are suitable.
What coating do PGC/B, LBE-ID and TPA have?
Tinning with 20 µm of tin, and TPA/D are fixed with M12 stainless steel screws.
How do TR, TRE, TRM and TRT differ?
TR has a straight entry, TRE a 90° entry, TRM a simple branch, and TRT a T-shaped one.
Which dies suit the crimped clamps?
Dies CDC5 and CD13 for hydraulic presses, round or elliptical.
