12/20kV Single Core Aluminium Conductor Cable for Underground Power Distribution

12/20kV Single Core Aluminium Conductor Cable for Underground Power Distribution

Product Overview

Our 12/20kV Single Core Aluminium Conductor Cable is designed for medium-voltage power transmission and distribution in utility networks, industrial facilities, substations, and infrastructure projects. Featuring a stranded aluminium conductor and XLPE insulation system, this cable provides a practical solution for fixed electrical installations requiring reliable power transmission.

The single core construction is suitable for applications where individual phase conductors are installed separately according to the electrical system design. Aluminium conductors offer a lightweight alternative to copper, helping reduce cable weight and conductor material costs when the appropriate conductor cross-section is selected.

For demanding installation environments, the cable can be customized with longitudinal water-blocking components, flame-retardant materials, and anti-termite protective measures. Metallic screening, armour, and outer sheath materials can also be specified according to project requirements.

As a cable manufacturer, we support customized cable construction, technical documentation, bulk orders, and export supply for electrical distributors, EPC contractors, utilities, and industrial project buyers.

Key Features and Benefits

• Aluminium Conductor: Stranded aluminium conductors provide a lightweight and cost-effective solution for medium-voltage power distribution.

• XLPE Insulation: Cross-linked polyethylene insulation provides electrical insulation and thermal performance suitable for medium-voltage cable applications.

• Water-Blocking Options: Optional longitudinal water-blocking materials help limit water propagation along the cable.

• Flame-Retardant Options: Suitable cable constructions can be specified according to the required flame-retardancy test standard.

• Anti-Termite Protection: Optional protective sheath materials or treatments are available for cable routes exposed to termite activity.

• Flexible Cable Design: Conductor cross-section, metallic screen, armour, and outer sheath can be customized to suit the installation environment.

• Project-Based Supply: Technical datasheets, routine test documentation, drum specifications, and other agreed project documents can be provided as applicable.

Typical Applications

The 12/20kV single core aluminium conductor cable is suitable for:

• Medium-voltage underground power distribution networks

• Utility substations and distribution feeder circuits

• Industrial plants, factories, and manufacturing facilities

• Commercial buildings and infrastructure developments

• Power distribution systems in industrial parks

• Renewable energy electrical infrastructure, subject to system design requirements

• Underground cable routes requiring additional moisture or mechanical protection

Cable selection should be based on the network voltage, load current, installation method, short-circuit requirements, earthing arrangement, and applicable electrical regulations.

Technical Specifications

The table provides a preliminary product specification. Final dimensions, electrical parameters, and construction details shall be confirmed in the approved technical datasheet.

Manufacturing Quality and Standards

The cable can be manufactured according to the agreed technical specification and applicable product standard. Quality control may include conductor resistance measurements, insulation and sheath thickness checks, and applicable electrical routine tests.

IEC 60502-2 is a relevant standard for medium-voltage power cables with extruded insulation. Additional requirements for flame retardancy, water penetration, and other environmental performance should be specified separately where required.

Technical datasheets, available type-test reports, routine test records, and third-party inspection arrangements can be discussed during the quotation and technical review process. Certification and test claims will depend on the actual product design and supporting documentation.

We support customized orders for international distributors, electrical contractors, utilities, and industrial projects.

Available options may include:

• Different aluminium conductor cross-sections

• Specified copper screen sizes and configurations

• Water-blocking materials for longitudinal water protection

• Flame-retardant and anti-termite protective constructions

• Suitable armour and outer sheath materials

• Customized cable lengths, wooden or steel drums, and export packing

Frequently Asked Questions

1. What is a 12/20kV single core aluminium conductor cable used for?

It is used in medium-voltage distribution networks, substations, industrial facilities, and underground feeder circuits designed for the corresponding voltage rating.

2. Can this cable be supplied with waterproof, flame-retardant, and anti-termite features?

Yes. Optional water-blocking, flame-retardant, and anti-termite constructions can be specified according to the installation environment and applicable test requirements.

3. Why choose an aluminium conductor instead of copper?

Aluminium offers lower conductor weight and can reduce conductor material costs. The required conductor size should be determined by current-carrying capacity, voltage drop, short-circuit performance, and installation conditions.

4. Which standards apply to this cable?

IEC 60502-2 is a relevant standard for medium-voltage extruded-insulation power cables. Additional project or national requirements may also apply.

5. Can you provide customized specifications and technical documents?

Yes. Conductor sizes, screen configuration, sheath materials, protective options, and drum lengths can be discussed. Available datasheets and applicable test documents can be provided for review.
