The Johannesburg branch held its latest technology evening on 11 May where Thierry Logeais, technical sales manager for Nexans cables, explained how cable problems can be prevented through use of its patented Hypron cable and jointing technology, targeted mainly at the refinery and petrochemical industries.
Safe refining and petrochemical processing depend on a wide range of cables that must survive in an environment where there are serious risks of damage due to the penetration of chemical products (acids, bases, aliphatic and aromatic hydrocarbons). This is why they were traditionally covered with a lead sheath and buried to ensure safety and process continuity.
Although a good protective barrier, lead has several drawbacks as it is neither biodegradable nor recyclable. Thierry introduced members to Hypron cables, the environmentally friendly alternative to traditional lead sheathed cables. The technology took five years to develop and consists of three concentric, co-extruded sheaths working together to provide the necessary characteristics:
* An inner aluminium polyethylene tape for water resistance.
* High density polyethylene sheath for resistance to inorganic chemicals (chlorine, synthetic oils).
* Polyamide for resistance to organic chemicals (aromatics, benzene, petrol, oil).
Hypron technology can be used to supply a full range of refinery/petrochemical cables including energy, control, instrumentation and communication. These cables are especially tough, resistant, and nearly indestructible because of the excellent adhesion between the three extruded protective layers. They can be customised to offer fire-reaction (reduced flammability, fire spread, heat release smoke emission and toxicity) and fire-resistance (electrical continuity under fire conditions) and can also be protected against rodents, UV and sulphur.
