Abstract
The invention discloses a crosslinked polymer composite insulated control cable used for the third generation of nuclear power station. The cable comprises copper conductors. The copper conductors are wrapped by 6-8 layers of mica tapes and then extruded by a polyolefin copolymer insulating layer so as to obtain an insulated wire core. Multiple insulated wire cores are twisted and then an inorganic flame-retardant layer is filled in the external wall so as to form a cable core. A fireproof mud layer is closely extruded outside the cable core, and then an armored copper sheath is interlocked outside the fireproof mud layer. A thermoplastic halogen-free low-smoke flame-retardant polyolefin external protective layer is extruded outside the copper sheath. The cable is reasonable and simple in structure, easy to produce and manufacture, low in cost, great in use performance and convenient to install. The cable has excellent fireproof, corrosion-resistant, anti-aging and external force impact resisting functions and also realizes the characteristic of electric energy transmission and is suitable for trunk lines, fire-fighting lines, escape and rescue systems, emergency lighting, fire monitoring, alarm systems, elevator systems, smoke evacuation systems and control lines.
