1.Application (Instrument cables):
BS 5308 cables are designed to carry communication and control signals in a variety of installation types including those found in the petrochemicals industry. The signals can be of analogue, data or voice type and from a variety of transducers such as pressure, proximity and microphone. Part 1 Type 3 cables are generally designed where a greater degree of mechanical and chemical protection is required or direct burial at a suitable depth. Collectively and individually screened pairs are available within the range. For installations where fire, smoke emission and toxic fumes create a potential risk to life and equipment.
