Frequently Asked Questions

1. What is the difference between insulated aerial cables and sheathed aerial cables?

Insulated aerial cables have insulation around their conductors. Sheathed aerial cables may include an additional protective outer layer, such as the HDPE jacket used in CCSXT.

2. What is the difference between AAC and AAAC conductors?

AAC is an all-aluminium conductor, while AAAC is an all-aluminium-alloy conductor. Their electrical and mechanical properties differ, so the appropriate type should be selected according to the line design.

3. Which insulation materials are available?

The listed product range includes XLPE and PVC insulation. CCSXT also features an HDPE outer sheath.

4. Are these cables suitable for medium-voltage overhead networks?

CCX is listed for applications up to 35 kV in the supplied documentation. The rated voltage and cable construction must be verified against the project requirements before selection.

5. Can special core configurations be supplied?

The supplied catalogue includes various single-core, multi-core and supplementary conductor configurations. Please provide the complete cable designation or technical drawing for confirmation.

6. What information is required for a quotation?

Please provide the cable type, conductor cross-section, core arrangement, insulation material, rated voltage, applicable standard, required quantity and destination port.
