TRATOS® PAS 5308 Part 2/Type 1 – Unarmoured Construction

Publicly Available Specification PAS 5308-2 replaces BS 5308-2 and provides additional aspects not covered in the European standard for control and instrumentation cables, BS EN 50288-7. 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 manufacture a complete range of control and instrumentation cables for industrial applications. Tratos control and instrumentation cables are available with either Class 2 or, to aid installation and allow repeated removal of meters for calibration, Class 5 conductors. Tratos control and instrumentation cables are available with individual or collective screens to confine the electric field and to limit the external electrical influences. In the Publicly Available Specification, cables are designated according to their construction, type 1 cables are unarmoured, type 2 cables have a single wire armour. Both types of cable have a PVC outer sheath.

Electric cables used for the supply of electricity and for control and communication purposes, which are intended for use in buildings and other civil engineering construction works are covered by the Construction Products Regulation No. 305/2011 and subject to performance requirements on reaction to fire.

Tratos control and instrumentation cables are available as class Cca (BS EN 50575) as standard, higher classifications are available on request

The ranges of control and instrumentation cables have been rationalised to preclude certain cable types and conductor sizes in accordance with current industry practice.
