Power Distribution & Transmission

BASEC's approved mark provides purchasers and contractors with the peace of mind that the cable they install is safe, fit for purpose and compliant with all the relevant standards.

Huge structural changes are currently underway to the generation, transmission, distribution, supply, and use of electricity. This, coupled with an ageing existing infrastructure, means that it’s essential that the cabling supplied provides a reliable, long term service and is critical to the reputation and efficiency of companies operating in this sector.

BASEC has been operating independently for over 45 years and our certification scheme is recognised as one of the most demanding in the industry. Manufacturers of BASEC approved cables are subject to regular factory inspections. Cables are sampled and tested several times a year to ensure ongoing conformity.

This rigour means that when purchasers and contractors specify BASEC approved cable they can be sure it meets the highest quality standards and that it conforms with all relevant regulatory requirements.
