construction elements. The AluPE layer features an aluminium coated tape, applied longitudinally, that provides a watertight seal. The High Density Polyethylene (HDPE) sheath provides resistance to inorganic chemicals such as chlorine. The third element – the PA sheath – provides resistance to organic materials such as benzene. Providing the same level of protection against aggressive petrochemicals as traditional lead-sheathed cables, Nylon also features improved ease of handling and installation. Tratos – UK Website : www.tratos.co.uk twister lines are the universal rotating cabler/armourer for laying-up of copper or aluminium conductors. Planetary lines are available for steel wire armouring of fibre optic and large submarine power cable and umbilical cables. Setic, of Roanne, France, offers complete bunching/stranding solutions for the power cable and automotive industry as well as producing high quality special/LAN cables with enhanced performances (in one step or two steps according to product mix). The range includes high speed double twist bunchers for 7, 19, 37 wires (unilay construction) or multiwires bunches, large double twist stranders/cablers for 7, 19 wires strands and assembling of conductors, double/triple twist twinners/ quadders, ideal for all pairing operations for special/LAN cable; group twinners for twinning and stranding of high-end LAN cable in one tandemised operation; and single twist cablers/stranders for cabling of quality insulated cables.

Nylon, from electric and fibre optic cable manufacturer Tratos, is an environmentally friendly alternative to lead-sheathed cables for onshore power, control and instrumentation applications in the oil and gas industry. These challenging environments call for exceptional durability from all equipment, especially cabling that may be permanently open to the elements or used alongside heavy duty, industrial equipment. In response to the growing market demand for more environmentally friendly cables, Tratos has developed a new lead-free barrier in its Nylon cable. Both Pourtier and Setic, members of the Gauder Group, provide high quality rotating machines (bunchers, stranders and cablers) with the highest standards in design and manufacturing. Pourtier, based in Chelles, France, develops comprehensive solutions for the production of all types of high voltage and extra-high voltage power cables, from overhead to insulated, AC or DC type. Its rigid stranding lines – stranding up to 127 wires, copper, aluminium and aluminium alloy – are specially designed to produce a new generation of overhead conductor made of trapezoidal wire (ACSS/ TW, ACCC) and also suitable for round compacted cores for HV/DC cables, sector cores for Milliken cables, regular overhead conductor (ACSR, AAAC) as well as steel wire armouring and copper wire screening. The concentric stranding solution – stranding of copper, aluminium and aluminium alloy – is perfectly adapted for 37 wires bare copper and aluminium compacted strand production at high speed. To complete the operation, drum Nylon comprises three co-extruded
