Abstract

The invention relates to a salt corrosion-resistant and torsion-resistant composite cable and a manufacturing method thereof. A power cable insulation layer, a control cable insulation layer and an instrument cable insulation layer are salt corrosion-resistant and torsion-resistant rubber insulation layers. A power cable core, a control cable core and an instrument cable core are twisted into a composite core. The periphery of the composite core is coated with a low-intensity non-woven longitudinal cladding. A sheath is arranged at the periphery of the low-intensity non-woven longitudinal cladding by means of extrusion. The low-intensity non-woven longitudinal cladding which has a shape completely consistent with the appearance of an insulated wire core is adopted, and the gap between the low-intensity non-woven longitudinal cladding and the insulated wire core is eliminated, so that flame can be prevented from spreading to the inside under the condition of combustion, and the resistance to moisture impregnation can be enhanced. Moreover, the low-intensity non-woven longitudinal cladding can ensure that the sheath and the insulated wire core are not adhered together, and the insulated wire core is not damaged when the sheath is tripped in the process of construction.

Description

technical field [0001] The invention relates to a composite cable, in particular to a salt and corrosion resistant composite cable. The invention also relates to a method for manufacturing the salt-corrosion-resistant composite cable. [0002] technical background [0003] With the maturity of land-use wind power utilization, the country has begun to promote the use of offshore wind power, but at present there is no cable dedicated to offshore wind power that can fully meet the operating conditions of offshore wind power to match it, and most of them are matched with cables originally used for land-use wind power It is used for offshore wind power, or a cable with certain performance required by the cable for offshore wind power is used. However, the performance of cables for land-use wind power does not take into account the special environment of offshore wind power, especially does not have the ability to withstand long-term ocean salt, acid, alkali corrosion, oil corrosi...
