Copper Clad Aluminum Busbar For Rail Transit

Material selection: High-purity aluminum rods (99.7%) + Oxygen-free copper strips (99.9%)

Coating: Copper strips are wrapped around the aluminum core and then welded at high temperature to form a composite billet.

Stretching: Through multiple molds, the copper-coated aluminum conductor is stretched to obtain the specified specifications

Tempering: Low-temperature tempering treatment to enhance the flexibility and conductivity of the conductor

Testing: Full-process online testing (copper layer thickness, conductivity, dimensional accuracy)

Wire and cable industry: Power cables, control cables, communication cables conductors, reducing the overall weight and cost of cables

Electrical appliances: Motor windings, transformer coils, switch components, improving the heat dissipation performance of equipment

Rail transportation: Line bundles for high-speed rail and subway, lightweight design to reduce the load on the vehicle body

New energy equipment: Photovoltaic inverters, energy storage battery connection lines, adapting to high-power transmission requirements

Building wiring: Home wiring, engineering wiring, offering better cost performance than pure copper wires

Specification Customization: Support customization of round wires/flat wires with different diameters and cross-sectional dimensions

Surface Treatment: Tin plating or nickel plating to enhance welding properties and corrosion resistance.

Packaging Customization: Provide packaging options such as rolls, coils, and cut pieces according to customer requirements, to meet the feeding requirements of automated production lines

Technical Support: Provide product selection suggestions and processing process guidance to assist customers in optimizing product solutions

Q1: Could copper-clad aluminum conductors replace pure copper?

A: They can completely replace pure copper in medium and low voltage, short-distance transmission scenarios (such as home wiring, control cables), and offer better cost performance; for long-distance high-voltage transmission, it is recommended to select the model based on actual needs.

Q2: How is the welding performance of copper-clad aluminum conductors?

A: The outer copper layer has excellent welding properties and can be welded using methods such as soldering or argon arc welding, ensuring a secure and non-detachable connection.

Q3: How long is the delivery period for the product?

A: Standard specifications are delivered within 5-7 working days of order placement, while custom specifications take 10-15 working days.
