Industrial fireproof high-temperature-resistant power cable

Abstract

The invention discloses an industrial fireproof high-temperature-resistant power cable, comprising a cable body that includes a plurality of conductors, an insulating layer, a shielding layer and an outer sheath. The cross section of the cable body is circular in shaped; the plurality of conductors are arranged in the cable body; a layer of rubber framework is arranged outside the conductors; the insulating layer is arranged outside the rubber framework; a filling layer is arranged at the gap part between the insulating layer and the rubber framework; the shielding layer is tightly extruded outside the insulating layer; the shielding layer includes a refractory layer, a glass fiber reinforced plastic fiber layer and a aluminum plastic composite strip layer which are sequentially extruded from inside to outside; the outer sheath is extruded outside the aluminum plastic composite strip layer. The industrial fireproof high-temperature-resistant power cable has the advantages of reasonable structural design, high temperature resistance and long service life.

Description

technical field [0001] The invention relates to the field of cables, in particular to an industrial fireproof and high temperature resistant power 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. Gases harmful...

[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.
