Vexila wins four-year Eskom contract

Vexila has announced that the company has been awarded a tender for the procurement of designing, manufacturing, testing and supplying of high-voltage composite insulators for Eskom Holdings SOC Ltd. This tender will run for a period of four years. Vexila is the only manufacturer of high voltage composite insulators in Africa.

The high-voltage composite insulators are long rods and line posts between 220kV and 400kV for Eskom’s transmission division.

Vexila is an electrical hardware developer and manufacturer. They are one of the pioneers of electrical power transmission and distribution and the largest composite insulator manufacturer and the only manufacturer of HV composite insulators in Africa. Vexila is also a specialist in the manufacturing of world class electrical products used in power transmission and distribution including solation gear, protection gear and railway catenary systems.

Key manufacturing facilities at the Pietermaritzburg, KwaZulu-Natal based company include silicone rubber injection moulding, gravity cast aluminium and ductile iron foundries, a helical wireform production plant, a fibreglass reinforced polymer core pultrusion plant and a tool and die development and manufacturing facility.

African first: 765kV composite insulators
Vexila has also confirmed the attainment of another significant milestone in its OEM product development journey. The successful development of its very own 765kV composite long rod insulator of African origin. The new product, rated at 300kN and in excess of 6.6 metres in length, was developed, designed and manufactured by the Vexila team in Pietermaritzburg, KwaZulu-Natal. The company has successfully completed a rigorous technical evaluation and type testing programme based on IEC standards at various internationally certified laboratories.

“This achievement places us in a niche, capable of addressing 765kV infrastructure needs in high pollution, vandal resistant, low maintenance environments and underscores our innovation and ingenuity in addressing our customers’ needs,” said CEO Gary Whalley.

“Operating an innovative, vertically integrated manufacturing facility, equipped with efficient in-house processes, technologically driven equipment and a highly competent team, Vexila is a trusted brand to meet and exceed our customer’s expectations,” says Whalley.
