2. Mineral-insulated copper-clad cable - Wikipedia

   en.wikipedia.org/wiki/Mineral-insulated_copper...

   The cable meets and exceeds BS 5839-1, making it fire-rated surpassing 950°c for over three hours with simultaneous mechanical stress and water spray as well without failure. MI cable is primarily used for high-temperature environments or safety-critical signal and power systems; however, it can additionally be used within a tenanted area ...

3. Plenum cable - Wikipedia

   en.wikipedia.org/wiki/Plenum_cable

   The fire requirements on riser cable are not as strict. Thus, plenum cable can always replace riser cable, but riser cable cannot replace plenum cable in plenum spaces. Both plenum and riser cables commonly include a rope or polymer filament with high tensile strength, which helps support the weight of the cable when it is dangling in an open ...

   Circuit integrity fireproofing of cable trays using calcium silicate board system Circuit integrity fireproofing of cable trays Fire-resistant cables MI cables fastened into junction box that has not been fireproofed. Circuit integrity describes the extent of a fire's effect on an electrical circuit's operation. It is a form of fire-resistance ...

5. Thermoplastic-sheathed cable - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic-sheathed_cable

   If the label says "12-3", this cable has four conductors—three 12-gauge insulated wires and a bare copper ground wire. [ 5 ] Different types of cables are approved for different applications; the cable used for interior wiring in dry locations is different from the types approved for underground burial, direct embedment in concrete, or ...

6. Linear heat detection - Wikipedia

   en.wikipedia.org/wiki/Linear_Heat_Detection

   Linear heat detection (LHD) (also known as linear detection wire or linear heat detection cable or linear heat) is a very commonly used method of fire detection. It can detect a fire anywhere along the length of the cable, and can be of lengths in excess of a kilometer. Applications can range from building fire alarm systems to mobile plant ...
