Top Cable Lug Manufacturer in China
Cable lugs play a crucial role in electrical systems by connecting cables to devices and equipment. As the top cable lugs manufacturer in China, Enze offers various cable lugs for your projects. If you require customized cable lugs with different applications, Enze is your top choice.
The Function of Cable Lugs
Cable lugs serve an essential function in electrical systems. They are designed for easy installation and disassembly, making repair and maintenance a breeze. The cable lug is attached to the cable either by welding or crimping, and the connecting end can be fixed to the corresponding position or connection point using bolts, screws, or spring clips. Cable lugs come in various sizes, configurations, and material types to suit specific applications, but aluminum and copper are the most commonly used material. They are used in power cable systems, automobiles, machinery, household appliances, electronic products, and other wiring systems. For safety reasons, cable lugs are typically insulated with rubber or plastic to prevent accidental electrocution or damage to nearby electrical components.
Featured Cable Lugs
Crimp lugs
Crimp lugs create a reliable connection by crimping them onto the cable.
Compression lugs
Compression lugs are compressed onto the cable with a special tool for a secure connection.
Cable Lugs Materials
Enze offers various material options in cable lugs for your projects, our experienced team ensures we can meet your specific needs with expertise.
Aluminum is lightweight and corrosion-resistant, making it suitable for cable lugs in outdoor installations. It also has lower electrical conductivity than copper and is suitable for power and utility applications where space is not a constraint.
Copper is excellent for conductors of electricity with low thermal expansion, making them non-fire hazards. They are widely used in electrical applications and suitable for indoor and outdoor use. However, copper is more expensive than aluminum, which is why aluminum was used before copper.
Copper and brass require thorough cleaning to remove tarnish and oxides before powder coating.
Brass cable lugs are perfect for marine applications because of their exceptional corrosion resistance.
Bimetallic lugs are used when terminating an aluminum cable with a copper bus bar or contact to prevent galvanic action from dissimilar contact, Ensuring a durable joint.
Cable Lugs Surface Finishes
Tin plating is crucial for cable lugs, and the thickness is measured in microns using a digital meter to ensure uniform coating. There are generally two types: smooth and textured finish. Smooth finishes offer low electrical resistance and good corrosion resistance, while textured finishes provide better grip and are ideal for situations involving vibration or movement.
Cable Lugs Machining & Fabrication Process
Drawing, forging, and CNC machining are the three main processes of cable lugs
1. Drawing
Drawing is a fabrication method that feeds the raw material through a series of steel dies with gradually decreasing diameters. Aluminum alloys are preferred due to their strength-to-weight ratio and recyclability.
2. Forging
The forging process is critical for cable lugs and includes the following steps:
a) Heating aluminum rods
b) Removing the rods from the oven and forging
c) Cooling the rods in water
Forging enhances aluminum parts’ strength, ductility, and toughness, generating minimal material waste and making it an efficient production method.
3. CNC Machining
The CNC machining of cable lugs is an efficient and cost-saving process that involves:
a) Edge cutting
b) Hole drilling
c) Threading
d) Deburring
This process ensures that the cable lugs are shaped with high precision and accuracy to meet the customer’s required specifications.

FAQS
Enze cable lugs are used to terminate and connect cables in electrical components with stud or nut and bolt terminals—available sizes from 6mm to 50mm.
A cable lug is a device used to connect a wire to an electrical terminal. A cable link connects two or more wires. Consider the application, environment, and power level to choose the right material for your cable lug. This ensures optimal and secure performance in your electrical projects.
Understanding cable lugs’ various types, materials, and uses is crucial for ensuring optimal performance and security in your electrical installations. For details, visit How to Select the Cable Lugs
Aluminum is cheaper but has caused problems before. Copper is good but expensive. We have to consider the difference between the two carefully.
Electrical manufacturers are often attracted to the low cost of aluminum. While copper has been the preferred choice for lugs, recent aluminum-related innovations have made them just as safe. Aluminum lugs are now coated with copper to prevent rusting and oxide formation on the surface.
Aluminum was not the right choice for lugs, but it is now much safer to use aluminum lugs than in the early days. Despite these improvements, the impression that copper lugs are better than aluminum persists. People may need more time to trust aluminum than copper.
