Product Specifications

Note: The final cable construction and technical parameters should be confirmed according to the applicable standard and project specification.

3x300mm² 26/35kV Cable Construction

The exact construction can be customized according to the required electrical, mechanical and environmental conditions.

1. Aluminium Conductor

The cable uses a 300mm² stranded aluminium conductor for power transmission.

Aluminium conductors offer a combination of electrical performance and lower weight compared with equivalent copper conductor constructions, making them widely used in medium voltage power distribution and large-scale infrastructure projects.

2. Conductor Screen

A semi-conductive conductor screen is applied over the conductor to provide a uniform electrical field between the conductor and XLPE insulation.

3. XLPE Insulation

The conductor is insulated with cross-linked polyethylene (XLPE).

XLPE is widely used in medium voltage power cables because of its electrical insulation properties and suitable thermal performance.

4. Insulation Screen

A semi-conductive insulation screen is applied over the XLPE insulation to maintain a controlled electrical field around the insulated conductor.

5. Metallic Screen

The cable can be supplied with a copper wire screen, copper tape screen or other specified metallic screen construction.

The screen design can be selected according to the required earth fault and short-circuit performance.

6. Filler and Binding

Suitable filler and binding materials can be used to maintain the roundness and mechanical stability of the three-core cable.

7. Armor

Armored versions can be supplied when additional mechanical protection is required.

The armor construction depends on the cable standard, installation environment and project requirements.

8. Outer Sheath

The outer sheath protects the cable against mechanical damage and environmental influences.

PVC, PE, LSZH and other sheath materials can be considered according to the project specification.
