Abstract

The invention relates to a composite cable for a flame-retardant fireproof boat and a manufacturing method thereof. A power cable core, a control cable core and an instrument cable core are stranded into a composite cable core; the periphery of the composite cable core is coated with a low-intensity non-woven fabric longitudinally-covered layer; an inner jacket is extruded on the periphery of the low-intensity non-woven fabric longitudinally-covered layer in a wrapping way; the periphery of the inner jacket is coated with an armor braid; and an outer jacket is extruded on the periphery of the armor braid in a wrapping way. The low-intensity non-woven fabric longitudinally-covered layer is completely in fit with each insulated conductor in shape, so that gaps between the low-intensity non-woven fabric longitudinally-covered layer and the insulated cores are eliminated, and flame can be conveniently prevented from being spread inwards; and meanwhile, the inner jacket and the insulated cores are guaranteed not to be adhered, so that the insulated cores are not damaged when the jacket is stripped in the constructing process.

Description

technical field

[0001] The invention relates to a composite cable, in particular to a flame-retardant and fire-resistant composite cable for ships. The invention also relates to a manufacturing method of a flame-retardant and fire-resistant marine composite cable. Background technique

[0002] At present, fire-resistant marine composite cables generally adopt several structures such as mica tape wrapped conductor, mineral insulation, and extruded refractory silicone rubber outer braided glass fiber wire combination insulation, etc., but these types of fire-resistant cables have great disadvantages:

[0003] Mica tape wrapped fire-resistant cables are wrapped with mica tapes overlapping outside the conductor. Due to the large number of cores in marine cables, wrapping with mica tapes will result in large outer diameter and heavy weight of the finished cable, which is not conducive to ship loads.

[0004] The remarkable feature of mineral insulated cables is that the conducto...
