A copper-core armored power cable with a fire extinguishing function

Abstract

The invention discloses a copper-core armored power cable with a fire extinguishing function, the cable includes an armored cable body, the inside of the armored cable body is fixedly connected with afixing device, a cable core is fixedly connected to the inside of the fixing device, the outer side of the cable core is fixedly connected with an insulating layer, the outer side of the insulating layer is fixedly connected with a shielding layer, the outside of the fixing device is filled with a filling layer, and a first protective layer is fixedly connected to the outer side of the filling layer. The fixing device is arranged to fix the cable core and a fixing baffle plate is arranged as a member made of heat dissipating silicone rubber which has good elasticity and extensibility and playing a fixing role, so that the stability of the cable core is improved, and the cable core damage phenomenon is prevented;, at the same time, heat dissipation silicone rubber has good heat dissipationperformance, dissipates the heat generated by the cable core in time, avoids the high temperature of the armored cable body, and prolongs the service life of the armored cable body.

Description

technical field [0001] The invention relates to the technical field of armored cables, in particular to a copper core armored power cable with fire extinguishing function. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, power station lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. Armored cables are made of conductors of different materials. The metal casing of the material is processed into a bendable solid assembly. [0003] At present, the commonly used armored cables cannot fix the cable core, which will easily lead to loose fixation of the cable core, poor stability, and easy deformation and damage of the cable core. When the armored cable is in use, a large amount of heat will be generated, and the heat will easily cause Cable damage will reduce the service life of the...

Problems solved by technology

[0003] At present, the commonly used armored cables cannot fix the cable core, which will easily lead to loose fixation of the cable core, poor stability, and easy deformation and damage of the cable core. When the armored cable is in use, a large amount of heat will be generated, and the heat will easily cause Cable damage will reduce the service life of the armored cable and affect the normal use of the armored cable; the general armored cable has a certain fire-retardant effect, but it does not have a fire-extinguishing function, and cannot prevent the armored cable from igniting in time, causing the fire to spread, resulting in A large number of armored cables are damaged, causing unnecessary losses. A mineral insulated cable (authorized announcement number CN205230642U) is disclosed in a Chinese patent. Prevent the spread of fire; the surface of ordinary armored cables is relatively smooth, and it is easy to slip during installation or transportation, causing inconvenience in use
