Bimetal Cable Lugs

Bimetal Cable Lugs

Bimetal Cable Lugs Manufacturer & Supplier – CONWELL

CONWELL is a professional Chinese manufacturer and supplier of high-performance bimetal cable lugs. Our products are designed to connect aluminum cables to copper terminals, delivering stable conductivity and mechanical strength for power distribution, transformer and grounding systems.
Made of high-purity copper and aluminum via friction welding or precision bonding, the lugs undergo anti-corrosion surface treatment. They combine great electrical performance, light weight and cost efficiency for mixed-metal wiring.
Certified to ISO 9001 and compliant with IEC standards, our bimetal lugs are widely used in overhead lines, transformers, grounding and copper-aluminum transition panels for distributors, power utilities and electrical contractors.

Bimetal Cable Lugs Introduction

Bimetal Cable Lugs Key Features

1. Dual-metal transition design: Specially developed for connecting aluminum cables to copper terminals, solving galvanic corrosion issues between dissimilar metals.

2. Reliable joint performance: Adopts friction welding or precision bonding technology. The copper and aluminum parts are tightly combined, featuring high mechanical strength and no separation risk.

3. Superior electrical conductivity: Copper end ensures low contact resistance; aluminum section maintains excellent current transmission, effectively preventing overheating.

4. Good anti-corrosion capability: Professional surface treatment resists oxidation and electrochemical corrosion, suitable for long-term use in harsh environments.

5. Lightweight & cost-saving: Lighter and more affordable than full-copper lugs, cutting down material and installation costs.

6. Standardized quality: Manufactured in accordance with IEC standards and ISO 9001 certification for consistent performance.

Bimetal Cable Lugs Material Composition

1. Copper Section
Made of high-conductivity copper for connection with copper terminals and busbars. It maintains low contact resistance and stable electrical performance.

2. Aluminum Section
Constructed from high-purity aluminum for crimping with aluminum cables. It is lightweight, flexible and cost-effective.

3. Bonding Process
Two metals are combined by friction welding or precision solid bonding, with strong structure and no separation risk.

4. Surface Treatment
Optional tin plating and anti-oxidation coating prevent galvanic corrosion, suitable for indoor and outdoor use.

Bimetal Cable Lugs Main Applications

Application Fields Detailed Usage Scenarios

Overhead power lines Line terminations and pole connections
Transformer stations Transformer inlet & outlet connections, busbar terminations
Grounding systems Equipment grounding and lightning protection connections
Industrial electrical projects Industrial machinery, motor control centers and mixed-metal wiring systems

Bimetal Cable Lugs Selection Guide

1. Match cable cross-section

Choose the lug size that fully matches the cross-sectional area of your aluminum cable to ensure sufficient contact area and avoid poor conduction.

2. Confirm voltage grade

Select LV-rated lugs for indoor distribution wiring and MV-rated models for overhead lines and transformer equipment with higher strength requirements.

3. Check bolt hole specification

Match the lug’s bolt hole diameter with terminal bolts (M6/M8/M10/M12) to prevent loosening caused by vibration or load changes.

4. Consider working environment

For outdoor, coastal, humid or corrosive areas, prioritize products with enhanced anti-corrosion surface treatment to extend service life.

5. Verify quality & standards

Pick products compliant with IEC relevant standards and ISO 9001 certification to guarantee safety and long-term stable operation.

6. Confirm processing craft

Prioritize lugs made by friction welding, which deliver firmer metal combination and better overall performance.
