Vexila (Pty) Ltd designs, manufactures and supplies a wide range of composite insulators, composite cut-outs and a variety of line hardware products for electrical rail, transmission and distribution overhead power line infra-structure. Established over 45 years ago, Vexila was founded as Hardware Assemblies before being acquired by the German-Swiss PFISTERER Group in 2003, a move that significantly advanced the company’s research and development capabilities and expanded its product range.

In 2018, the South African company, Thesele Group, acquired the business, rebranding it as Vexila and propelling it to become one of the largest manufacturers in the rail, transmission and distribution industry in Africa.
