Flexible fireproof high temperature resistant insulated cable

Abstract

The invention discloses a flexible fireproof high temperature resistant insulated cable. The cable comprises a cable body, wherein the cable body comprises conductors, an insulating layer, a shielding layer and an outer sheath, wherein the cross section of the cable body is of a circular structure, the cable body is internally provided with multiple conductors, and the conductors are fixedly connected by virtue of a rubber framework; the conductors are externally extruded and wrapped with the insulating layer, the insulating layer is internally provided with multiple filling adhesive tapes, and a filling layer is arranged in a clearance between the insulating layer and each conductor; the insulating layer is externally extruded and wrapped with the shielding layer, the shielding layer is externally extruded and wrapped with a metal extrusion layer, the metal extrusion layer is externally extruded and wrapped with a glass fiber polyester belt layer, and the glass fiber polyester belt layer is externally extruded and wrapped with the outer sheath. The cable has the advantages of high electroconductibility, high temperature resistance, long service life and the like.

Description

technical field [0001] The invention relates to the field of cables, in particular to a flexible fireproof and high temperature resistant insulated cable. Background technique [0002] At present, with the development of science and technology, industry and other fields are also making rapid progress, which brings about an increase in the amount of cables. Cables are usually similar ropes with several or several groups of wires twisted at least two in each group. Each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating covering layer. There are many types of cables, which can be used in many fields and different environments. They are different, so there are different requirements for cables. The existing cables cannot meet the needs because of their unreasonable structural design. General cables are prone to burning when they are at high temperature or when a fire occurs.

[0002] At present, with the development of science and technology, industry and other fields are also making rapid progress, which brings about an increase in the amount of cables. Cables are usually similar ropes with several or several groups of wires twisted at least two in each group. Each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating covering layer. There are many types of cables, which can be used in many fields and different environments. They are different, so there are different requirements for cables. The existing cables cannot meet the needs because of their unreasonable structural design. General cables are prone to burning when they are at high temperature or when a fire occurs. Gases harmful to the environment and human body will be released during the process, and damage to the cable skin will cause electrical fires and bring greater losses to people.
