As the actual manufacturer of these cables, not simply a distributor, Tratos has total control of the design, quality and manufacturing process from the purchase of the raw materials through to final testing and despatch to our customers. Having control of the manufacturing process Tratos can ensure compatibility with most makes and types of glands.

Tratos manufactures a complete range of cables for marine applications that are both safe and reliable when correctly selected, installed and properly used. Tratos radial field Medium Voltage cables are available with wire braid armours consisting of galvanized mild steel, tinned annealed copper or tinned bronze wires to suit the particular installation and application.

In the British Standard, cables are designated according to the type of outer sheath material used in their construction. Cables designated SW 2 have a sheathing material that is classified in BS 7655 as ordinary duty enhanced oil-resisting, flame retardant with reduced halogen gas emissions. (5% maximum HCl). Cables designated SW 4 have a sheathing material that is classified in BS 7655 as ordinary duty enhanced oil-resisting, with low emission of smoke and corrosive gases when affected by the fire. (0.5% maximum). However Tratos BS6883 Oil and Gas cables employ the superior unique Tratos JBA® sheathing compound, features of Tratos JBA® sheathing compound include: Tough yet flexible to ease installation in the confined spaces found onboard ships and offshore installation. Highly flame retardant resists flame propagation and surface spread of flame. Tratos JBA® sheathing compound matches the environmental conditions found indoor or outdoor onboard ships and offshore installations – a saliferous and corrosive atmosphere, 100% humidity, water spray and deluge, mineral oils, hydraulic oils, crude oil and diesel fuel.

For locations where drilling “mud” is present, for longest life Tratos recommends the use of SW4 designated cables.

For the ranges of single and multi-core MV cables have been rationalised to preclude certain cable types and conductor sizes in accordance with current industry practice and following UKOOA Guidelines for instrumentation, power and control cables for fixed and mobile production facilities.
