Abstract

The invention discloses a dual-fireproof control cable structure. The cable structure comprises a plurality of insulated wire cores each having a conductor and an insulating layer wrapping the conductor, and a group including a wrapping tape, a shielding woven layer, an outer sheath, and a fireproof woven layer, wrapping the insulated wire cores, and successively disposed from inside to outside. The plurality of insulated wire cores and gaps between the insulated wire cores and the wrapping tape are filled with dust rock-free wool ropes. The fireproof woven layer comprises a first fireproof layer and a second fireproof layer woven by dust rock-free wool ropes. The double fireproof layers at the outermost layer of the cable are constructed by double-layer woven dust rock-free wool ropes structure and filled with dust-free rock wool ropes, and have a better fireproof effect. A foamed phenolic resin layer in the double fireproof layers further improves the fireproof performance and thermal insulation performance of the cable. The cable is excellent in performance resistant to water, water steam, oxidation, aging, and has light weight, and high fireproof and heat insulation efficiency.

Description

technical field [0001] The invention relates to a cable structure, in particular to a double fireproof control cable structure. Background technique [0002] Control cables are commonly used in industrial and mining enterprises, energy and transportation departments, etc., so they are often used on the ground, where multiple cables are placed in parallel or crossed at the same time, in this case, it is very important for the heat dissipation of the control cable, especially the fire performance has very strict requirements. [0003] Fire resistance is the basic requirement for the cables used in the electric power industry. At present, the commonly used cables all have the required fire resistance performance, but the fire performance is still insufficient, and the use of fire protection materials significantly increases the quality of the cable, which brings great harm to the transportation and installation of the cable. Major inconvenience. Contents of the invention ...
