Our History

Advanced Product Technology (Pty) LTD was established in 1978 under the management of Jeff Jonsson. The company traded in the general electronic components and soon became the leading supplier of components in the Vaal Triangle.

In 1985 Jeff was joined by his brother Gary Jonsson and it was decided then to expand the business and develop as a distributor of Power semiconductors and related components, and also specialised electrical products including HRC fuses and fusegear, relays, timers, and silicone cable. In 1992 Allan Nilsen joined the organization, managing finance and administration for the group. Advanced Product Technology (APT) is now a leading supplier of specialised electrical products in Southern Africa. With the head office in Johannesburg and branches in Durban and Cape Town, APT services a wide range of industries including power reticulation (Eskom and municipal), lighting projects (industrial, commercial and, domestic), heavy industrial (iron and steel works), solar/photovoltaic, mining and commercial agriculture. The company represents various international principals, all of which are leading manufacturers in their field of electrical and electronic engineering. APT is ISO 9001 accredited and a level 1 BBBEE certification.
