TRATOS-MOD 02-527® – Single and Multipair Core Silicone Insulated

DEF STAN 02-527 fire survival cables incorporate silicone insulation, glass fibre braid and lacquered LFH (Limited Fire Hazard) cores with Special Tratos JBA® Limited Fire Hazard (LFH) Elastomeric Sheath for reduced levels of smoke and toxic fumes in the event of a fire.

DEF 02-527 cables are also designed to be installed and used in high temperature zones in Ministry of Defence (MOD) Naval Vessels.

These cables are constructed to be compact and circular and are designed to withstand the conditions of revving, temporary support and glanding into equipment and through bulkheads, that are accepted practices in the shipbuilding (surface vessels and submarines) and ship fitting industry.

These silicone insulated, glass fibre braid and lacquered cables are suitable for continued use within the temperature range -30°C to +105°C . The lower temperature limit refers to weatherdeck applications under ‘arctic’ conditions, and the maximum continuous conductor temperature to the combination of ambient temperature and temperature rise due to maximum current flow. The maximum continuous conductor temperature is to be 105°C .

In the event of a fire after combustion a residue of pure silica is produced contained within the glass fibre braid and this allows the cables to continue to function for a limited period of time.

Each individual cable has a unique NATO Stock Number, or National Stock Number (NSN) as it is known in the United States of America (USA).

The Nato Stock Number (NSN), nominal conductor area, nominal stranding and the conductor formations for these types of cables are detailed in DEF STAN 02-527, table C5.
