Embodiment

[0039] Step 1: Make the power core: twist 19 groups of annealed copper wires with a diameter of 2.62mm into a copper conductor with a diameter of 11.5mm, then use a 0.8mm semiconductor inner shield, a 3.4mm cross-linked polyethylene insulation layer and a 0.7mm The semiconductor outer shielding layer is co-extruded in three layers through an extrusion die to obtain the power core 1;

[0040] Step 2: Metal shielding: Wind the copper tape around the outer wall of the power core in step 2 through a winding machine until the outer diameter of the metal shielding layer 2 reaches 21.6mm;

[0041] Step 3: Dipping: the glass fiber is drawn out from the creel, and after passing through the tension control machine, it enters the dipping tank for dipping;

[0042] Step 4: Glue equalization: the dipped glass fiber is introduced into the rubber roller group, and the glass fiber is glued through the rubber roller group;

[0043] Step 5: One-time preheating: send the power core 1 with the m...

Abstract

The invention discloses a salt-corrosion-resistant and torsion-resistant control cable for ocean wind power, and belongs to the technical field of cables. The cable comprises a power wire core which is formed by a copper conductor, a semiconductor inner shielding layer, a crosslinked polyethylene insulating layer and a semiconductor outer shielding layer from inside to outside; a metal shielding layer is wound on the outer wall of the power wire core; an inner glass fiber resin layer is wound and cured on the outer wall of the metal shielding layer, a filling layer is wrapped on the outer wallof the inner glass fiber resin layer, and an outer glass fiber winding resin layer is wound and cured on the outer wall of the filling layer. The device is simple in structure and convenient to use,the torsional strength of the cable is effectively improved, the corrosion resistance of the cable is improved, and the service life of the cable is prolonged.

Description

technical field [0001] The invention discloses a salt-corrosion and torsion-resistant control cable for marine wind power and a manufacturing method thereof, specifically in the technical field of cables. Background technique [0002] 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 corrosion, and seawater moisture immersion res...
