Abstract

The invention relates to a manufacturing method of a composite cable. A power cable core, a control cable core and an instrument cable core are mutually twisted to form the composite cable; the periphery of the composite cable is coated with a low-intensity non-woven fabric longitudinal covering; an inner sheath is extruded on the periphery of the low-intensity non-woven fabric longitudinal covering; the periphery of the inner sheath is coated with an armored braid; and an outer sheath is extruded on the periphery of the armored braid. The low-intensity non-woven fabric longitudinal covering is completely coincided with the shape of an insulated conductor so as to eliminate a gap between the low-intensity non-woven fabric longitudinal covering and the insulated conductor and facilitate preventing inward spread of flame; and meanwhile, the inner sheath and the insulated conductor are guaranteed not to be adhered so as to facilitate not damaging the insulated conductor when the sheaths are stripped off in the construction 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 the 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 conductor is covered with a layer of inorganic r...
