Technical Bulletins

There is much uncertainty surrounding UV Stabilisation.  Very few specifications are explicit enough.  No product offers 100% UV resistance.  There will always be some degradation.  This can range from a loss of surface gloss to cracking of the po

As from 24th January 2001 SABS 1507 became a compulsory specification. This means that all low voltage electric power cables installed in South Africa must comply with the stipulated requirements in SABS 1507.

Some customers mistakenly order Blue, Red or White stripe cables.  Given that SABS 1507 is compulsory (see Technical Bulletin 02) it is mandatory for such cables to have the following construction characteristics

In designing and producing cables, CBI-electric: african cables always subscribes to the latest version of the applicable specifications. The new numbering approach adopted by the SABS in 2000 is potentially confusing and this bulletin serves to clarify the matter.                          

Minutes or the TENTH meeting of SABS Technical Committee 66, held at 9:30 on 20 July 2001 in Committee Room M140, SABS, Groenkloof, Pretoria:

The Standards Division of the SABS has changed its name and will henceforth publish standards under the banner of Standards South Africa.

This technical bulletin has been created to explain the concept of volt drop to customers and provides an example on how to calculate volt drop from volt drop ratings given in African Cables Technical Dataheets
