Abstract

The invention provides an intelligent mineral insulated cable, which comprises a cable inner core structure and a cable sheath structure, wherein the cable inner core structure comprises a distributed optical fiber temperature sensing system, an optical fiber, a PBT sheath, a copper conductor and a mineral insulating layer, the cable sheath structure sequentially comprises a halogen-free low-smoke flame-retardant polyolefin inner sheath, a quartz net layer, a mica tape layer, a ceramic polyolefin sheath, a nylon sheath layer and a halogen-free low-smoke flame-retardant polyolefin sheath layer from inside to outside, and filling is arranged between the cable inner core structure and the cable sheath structure. The intelligent mineral insulated cable has the beneficial effects that the intelligent mineral insulated cable can transmit optical signals while transmitting power, can intelligently detect physical quantities such as stress, temperature, liquid flow rate, sound pressure, hydraulic pressure and magnetic field around the mineral insulated cable along with the change of working conditions, enables the mineral insulated cable to be in an optimal working state, and adopts the ceramic polyolefin sheath and the nylon sheath, so that the cable has the performance of being resistant to bite of rats and ants, fireproof, flame-retardant, green, environment-friendly and the like.

Description

technical field [0001] The invention relates to an intelligent mineral insulated cable, which belongs to the technical field of electric wires and cables. Background technique [0002] It is difficult for existing instruments and equipment to monitor the buried cables or the cables laid in the building walls in real time. Only after the cable fails, the fault point can be judged by the fault tester. At this time, damage is inevitable. If the cable operation data can be monitored in real time, when the cable is damaged, a timely warning can be received, and people can timely judge the location and type of the cable injury, and then protect the cable in time to reduce the occurrence of secondary disasters. [0003] In recent years, the loss of people's lives and property caused by fires in large-scale public entertainment places, commercial buildings, coal and chemical industries in China has made people have a deeper understanding of fire protection and fire safety.
