Explanation of Unusual or Complicated Terms

80/20 System: A preferential procurement framework mandated by South African regulations. Eighty percent of evaluation points are allocated based on competitive pricing, while twenty percent are reserved for historical ownership and socio-economic development goals (such as black economic empowerment and local enterprise participation).

DIN Rail Curve: Refers to equipment engineered to mount on standardized industrial metal rails (DIN EN 50022). The "curve" denotes the magnetic tripping characteristic, which defines how rapidly the breaker responds to sudden overcurrent or short-circuit events.

3KA: Represents a short-circuit breaking capacity of three thousand amperes. This indicates the maximum fault current the device can safely interrupt and isolate without sustaining internal damage or posing a safety hazard.

2P: Stands for two-pole configuration. The breaker simultaneously disconnects both the live and neutral conductors in a circuit, providing enhanced isolation and safety compared to single-pole devices.

Joint Ventures, Consortia and Subcontracting:

Most large tenders are composed of tasks in a number of different fields, and it is not always possible for a single company to cater for all of them, and therefore Joint Ventures and Consortia are formed to then submit a tender together.

Government tenders are also requiring the subcontracting of a percentage of the tender work, and the trouble is then finding Subcontractors to comply with the tender requirements

To assist companies with finding tender partners and subcontractors, you can now submit your contact details and company information on this page, so other interested parties can contact you for purposes of forming Joint Ventures and subcontracting
