Special Wire and Cable > Fire-Resistant Cable
Mica Tape + XLPE/Silicone Insulated, Individual & Overall Screened Multi-Pair Instrumentation Cable (300/500V)
Designed, produced and tested as an emergency data transmission cable, this instrumentation cable ensures high-frequency signal transmission under fire conditions, commonly used for data and voice transmission during fire events.
Available with either mica tape + XLPE insulation or silicone rubber insulation, and in non-armoured or galvanized steel wire armoured (SWA) constructions, the cable features both individual pair screening and an overall screen for superior noise immunity in demanding instrumentation environments.
