DRAKA Instrument Cable - Fire Resistant - Overall Screen - Armoured(SWA)
CU/MGT/XLPE/OSCR/LSHF/SWA/LSHF-AT-AR 500V to BS EN50288-7,
IEC60332-3-22, IEC 60331-21

Application

Instrumentation cables are used in data processing and process control.The electrostatic screen protect the screened pairs against outer electrostatic interference fields. Low level of line attenuations and low mutual capacitances enable long transmission distances fast pulse accelerations in damp locations, in open spaces and for underground laying. The cables are mainly used in petroleum and petrol chemical industry. Incorporation with layer of fire proof barrier, these cables are mainly used for those critical areas that require circuit integrity in the emergency systems such as emergency exit lights, emergency lifts, sprinkles, smoke and heat detectors etc.
