We manufacture a full range of aluminium overhead conductors to both international and national quality standards, from 7 strand conductors to 61 strand conductors. Aluminium Conductor Steel Reinforced (ACSR) are used in areas with less corrosive effects but can be greased to improve corrosion resistance.
All Aluminium Conductors (AAC) and All Aluminium Alloy Conductors (AAAC) are used in environments with aggressive corrosion. The AAAC conductors are used where longer spans are needed as their tensile strength is higher than that of the AAC conductors, however the carrying capacity of electrical currant of the AAC conductor is slightly higher than that of the AAAC conductor, assuming they both have the same dimensions.


We have developed and implemented a quality management system to:

• Document our best business practices;

• Better the requirements and expectations of our clients; and

• Improve the overall management of our company.

Our quality management system meets the requirements of, (and has been certified to) ISO9001, since 2001. The requirements of the standard are applied to enable us at Alcon Marepha, to consistently provide products that meet our clients’ requirements, and as such, international standards as per the SANS IEC 61089:1991.


Our on-site laboratory is equipped to ensure that all products are continuously tested to the strictest standards. Our training staffed are proficient in the requirements of our clients and to the relevant International Standards which ensures that our product is consistently meeting clients’ expectations.

The information contained in the standard tables is based on the following conditions:

• Ambient Temperature: 30°C
