Conductors

Conductors are the essential building blocks of every electrical system -- from the wiring inside a distribution panel to the overhead lines spanning kilometers of transmission corridor. The choice of conductor material, cross-section, and insulation directly affects system capacity, safety, and long-term reliability.

COPPERCORE distributes copper and aluminum conductors from established European manufacturers, covering cross-sections from 1.5 mm2 for control wiring up to 500 mm2 for high-current power transmission. Our range includes bare conductors, insulated conductors, busbars, and specialized grounding products.

We supply conductors to utilities building overhead line networks, contractors wiring industrial plants and commercial buildings, and panel builders assembling switchgear and distribution boards. Whatever the application, we provide the conductor types and quantities your project demands.

Copper Conductors

Copper remains the conductor of choice for most electrical installations due to its superior conductivity, mechanical flexibility, and corrosion resistance. We supply both solid and stranded copper conductors in cross-sections from 1.5 mm2 to 300 mm2, with PVC and XLPE insulation options.

In building installations, copper conductors are used for power distribution circuits, lighting, and control wiring. In industrial settings, they serve as connections between switchgear, motor feeds, and grounding systems. Copper busbars are the standard for distribution panel construction, carrying high currents in compact form factors.

When sizing copper conductors, the key factors are the maximum current-carrying capacity required, voltage drop over the installation length, ambient temperature conditions, and the installation method (conduit, tray, or direct burial). We carry standard metric cross-sections and can advise on the appropriate conductor size for your specific load and installation conditions.

Aluminum Conductors

Aluminum conductors offer a cost-effective and lightweight alternative for applications where large cross-sections are needed. At roughly one-third the weight of copper for equivalent current capacity, aluminum is the standard choice for overhead line construction, long-distance power distribution, and large industrial feeders.

In utility networks, aluminum and aluminum-steel (Al/Fe) composite conductors form the backbone of overhead transmission and distribution lines. The steel core provides mechanical strength for long spans, while the aluminum strands carry the electrical current. For underground and indoor applications, insulated aluminum conductors in cross-sections from 16 mm2 to 500 mm2 serve as feeders for large motors, transformer connections, and building main supply cables.

Key considerations when specifying aluminum conductors include the increased cross-section required compared to copper for the same current rating, special jointing and termination requirements to prevent galvanic corrosion, and thermal expansion characteristics that affect connection tightness over time. We supply the appropriate bimetallic connectors and installation accessories to ensure reliable aluminum conductor installations.

Special Conductors

Beyond standard copper and aluminum conductors, we carry a range of specialized products for specific installation requirements. Grounding conductors in bare copper and galvanized steel provide the low-impedance earth paths essential for electrical safety and lightning protection systems.

Copper busbars are available in flat, round, and custom-profile formats for distribution panel and switchgear assembly. We supply standard dimensions as well as cut-to-length services for busbars used in main distribution boards and industrial power centers.

Flexible conductors with highly stranded copper construction are designed for applications requiring repeated movement or vibration resistance -- including connections to motors on vibrating bases, portable equipment feeds, and draw-out switchgear connections.
