Traid PVC IS/OS Screened SWA BS5308 Instrumentation Cable Part 2 Type 2


 


 

 



Product Description


 


 


Application: BS5308 cables are designed to carry communication and control signals in a variety of installation types including the petrochemical industry. The signals can be of analogue, data or voice type and from a variety of transducers such as pressure, proximity or microphone. BS 5308 cables are designed to form part of an intrinsically safe system and the technical information required to determine their suitability for this application is contained within the datasheet. Part 2 Type 2 cables are designed where a greater degree of mechanical protection is required namely outdoor / exposed or direct burial at suitable depth. Being BS 5308 Part 2 the insulation material is PVC, whilst the PVC sheathing material has an OI >30% and HCL <15% and the LSZH material is of type LTS3. Individually and collectively screened pairs are available within the range where further signal security is required.
