Abstract

The invention discloses a full-thread temperature monitoring cable comprising a cable core, wherein the cable core is formed by twisting three main wire cores and one data wire together. A flame retardant glass fiber tape is filled at a gap of the cable core. A first impregnated non-woven fabric wraps the cable core. An electric calcined clay flame retardant layer is formed around the impregnatednon-woven fabric through extruding. An insulating layer is formed around the electric calcined clay flame retardant layer through extruding. A metal armor layer wraps around the insulating layer. An outer sheath is formed around the metal armor layer through extruding, and a second impregnated non-woven fabric wraps the outer sheath. The data wire is formed by wrapping two power conductors and onedata conductor with a PVC insulating layer through extruding, and temperature sensors for temperature feedback are mounted on the data conductor at an interval of 1 meter. The monitoring cable can monitor the temperature change of any point of the cable in real time, and also has strong flame retardant and fire retardant performance.

Description

technical field [0001] The invention relates to the field of cables, in particular to a full-thread temperature monitoring cable. Background technique [0002] As we all know, there are many reasons for cable fire accidents. One is that the external fire causes passive combustion of the nearby cables, which causes the internal temperature of the cable to rise or short circuit to further expand the fire. The other is that during the transmission process of the cable, if the current carrying capacity of the cable exceeds the allowable value, the temperature of the cable will start to rise. All-round real-time monitoring of cables by technical means is indispensable to ensure stable, safe, scientific and reasonable operation of the system. Therefore, a full-thread power cable with temperature detection and control functions has been developed, regardless of the internal or external reasons of the cable. , as long as the temperature of the cable itself is higher than the set va...
