Cabling conditions in Durban

Durban's humid, salty air is hard on anything electrical. Lugs and terminations near the beachfront, the Bluff and Umhlanga oxidise quickly, and moisture finds its way into poorly sealed joints, so tinned lugs, sealed glands and IP-rated enclosures are worth specifying. Summer thunderstorms bring frequent lightning, which makes surge protection and sound earthing important. The port, the south Durban refineries and industrial areas such as Prospecton and Jacobs use large volumes of armoured and XLPE cable. eThekwini supplies most of the metro, and apartment blocks and townhouse complexes are steadily upgrading old sub-mains and adding backup power.
