Problems solved by technology

[0002] At present, domestic high-rise buildings, petroleum, mining, metallurgy, ships, power stations, subways, tunnels and other fire safety requirements are high. Existing fireproof cables can only be used for ordinary fireproofing by using the material properties of the cable itself when a dangerous situation occurs. However, when there is a dangerous situation waiting to be discovered, it is generally because the fire has already spread, which may lead to untimely rescue and cause injury

Embodiment Construction

[0016] Such as figure 1 As shown, a flexible fire-resistant transmission signal cable for temperature measurement according to the present invention includes a cable core, and the cable core is formed by twisting three insulated cores and an optical fiber unit; the insulated core is composed of An aluminum alloy conductor 1, a semiconductive cloth tape 2 wrapped outside the aluminum alloy conductor, and an insulating layer 3 extruded outside the semiconductive cloth tape; the optical fiber unit is composed of an optical fiber 4, a metal shield wrapped outside the optical fiber Layer 5 and the first glass ribbon 6 extruded outside the metal shielding layer. Fill the gap of the cable core with glass fiber 8, extrude a flame-retardant and refractory layer 9 with a thickness of 2.65-3.65mm outside the cable core, and extrude a metal conductive tube 10 with a thickness of 2-4mm outside the flame-retardant and refractory layer. An outer sheath 11 with a thickness of 3-6 mm is provi...

Abstract

The invention discloses a temperature measurement soft fire resistant transmission signal cable which comprises a cable core which is formed by twisting three insulating wire cores and a fiber unit. The gap of the cable core is filled with glass fibers. A flame retardant fireproof layer is extruded outside the cable core. A metal conductive tube is extruded outside the flame retardant fireproof layer. An outer sheath is arranged outside the metal conductive tube. A temperature monitoring wire core is also arranged in the outer sheath and can monitor the temperature change of the cable in use, and external monitoring equipment is connected through a monitoring cable to carry out alarming.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a flexible fire-resistant transmission signal cable for temperature measurement. Background technique [0002] At present, domestic high-rise buildings, petroleum, mining, metallurgy, ships, power stations, subways, tunnels and other fire safety requirements are high. Existing fireproof cables can only be used for ordinary fireproofing by using the material properties of the cable itself when a dangerous situation occurs. However, when there is a dangerous situation waiting to be discovered, generally the fire has already spread, which may lead to untimely rescue and cause injury. [0003] Therefore, developing a kind of flexible fire-resistant transmission signal cable that can carry out monitoring and alarm has just become the problem that the personage in the industry urgently needs to solve. Contents of the invention [0004] The technical problem to be solved by the presen...
