TRATOS FIRESAFE – SWA/M1® – 600/1000 V – SWA Armoured Cable

LOW SMOKE ZERO HALOGEN (LSZH) CABLES HAVING ENHANCED CIRCUIT INTEGRITY WHEN EXPOSED TO FIRE - BASED ON BS7846

Special Cables / Fire Resistant Cables / Tratos Firesafe® BS

Tratos Firesafe SWA/M1 0.6/1kV armoured cables are manufactured in Italy and the United Kingdom in accordance with British Standard BS7846 and are IMQ-approved when circuit integrity is required in case of fire.

Protected circuits are required where it is critical that an electrical circuit continues to operate during a fire. This should include the use of sufficiently robust cables, careful selection of cable routes, and/or by the provision of physical protection in areas where cables may be susceptible to damage.

The cables are manufactured and supplied with for safety and building evacuation critical systems.

Tratos SWA/M1 0.6/1kV cables are constructed with mica tape barrier conductors, cross linked polymer insulated cores, which are overlaid with a LSZH bedding. The cables are single / steel wire armoured (SWA) and LSZH sheathed.

SWA Armoured Cable is used when cables have to be installed where mechanical protection is required. The following installation points have to be considered; Required tensile load, expected pressure on cable during service, rodent protection, protection against accidental damage, minimum required bending radius. A single layer of galvanised steel wires provides a very good mechanical protection and tensile strength.These SWA Armoured Cable are typically clipped and installed on to walls, ceilings and in certain external areas of buildings; they have an operating temperature range of -10ºC to +90ºC.

British Standards (BS) and Euro Norm (EN) for these types of fire resistance set out to test the integrity provided by a cable during fire in particular, circuit continuity at rated voltage. Each of these British Standards & Euro Norm is a specification for the actual fire test. They detail the design and dimensions of test rigs and how many cable samples are used, how they are prepared and how the burners are calibrated. They list the methods of cable attachment, how circuit continuity is measured, the test voltages and the burner gas and air mixture.
