DTL Series Bimetallic Lugs

Overview

Bimetallic Lugs are mostly useful where an aluminum cable has to be terminated by a copper bus bar or copper contact. Such as control panels, switchgear, and combiner boxes. If Cable Lugs of only copper or aluminum are used, a galvanic action occurs due to dissimilar contact. The use of bimetallic lugs thus ensures a technically sound and durable joint. The Aluminum barrel is friction welded to the copper palm thereby achieving the best possible transition between barrel & palm.

Advantages

1. Safe & low cost both in and use.

2. All copper products are electro-tinned to BS standard and prevents it from corrosion and oxidation.

3. Provides PVC insulation to terminals for excellent dielectric strength and support.

4. Entry to the wire barrel is shock-proof, or bell mouthed for faster and easier conductor entry.

Technical Data

DTL Bimetallic Lugs

Material: E-Cu; A1-99.6%
Surface treatment: Bright
Products property: Due to the coupling effect when Aluminum comes in contact with copper, corrosion will happen in a short time. Currently the best solution is to use Aluminum-Copper bimetal connectors. A bimetal lug should be used for termination. The friction welding is well done. And its barrel capped is billed with joint compound to avoid oxidization.

DTL-2 Bi-metallic lugs – Aluminum barrel with copper palm
