Pre-Insulated Bimetallic Lug, CPTAU

The Preinsulated Bimetallic Lug or Preinsulated CPTAU Lug is designed to establish secure connections between low-voltage overhead insulated conductors and copper equipment terminals. Suitable for both spin-welded and crimped terminal types, it accommodates cable sections ranging from 16 to 150 mm². This lug is ideal for applications requiring reliable electrical connections in overhead distribution networks.

Product Description

The Preinsulated CPTAU Lug features a bimetallic design with a copper palm and an aluminium barrel, ensuring efficient conductivity and corrosion resistance. The lug is pre-insulated with a thermoplastic sheath, providing electrical insulation and protection against environmental factors. Installation is straightforward, with clear markings indicating stripping length and crimping die size.
