Embodiment

[0031] Embodiment: Referring to the accompanying drawings, the manufacturing method of the special cable for wind power generation equipment in this embodiment, its manufacturing steps are as follows: material selection - wire drawing - conductor bundle stranding - isolation layer wrapping - insulation layer extrusion - insulation layer radiation crosslinking - insulation Wire core twisted into cable, gap filled and wrapped with isolation layer-outer sheath extrusion-outer sheath radiation cross-linking-finished product inspection-finished product;

[0032] The material selection is based on the performance requirements of the product, and formulates its procurement specifications and acceptance requirements for various materials required.

[0033] Extrusion of the insulating layer: using a semi-extrusion die, carried out on an ordinary extruder with a screw length-to-diameter ratio of 20:1 or 25:1 and a compression ratio of 2.5:1 or 2.0:1, extruding on the conductor isolation la...

Abstract

The invention relates to a manufacturing method of a special cable for wind-power generating equipment; the manufacturing method comprises the following steps of: selecting materials-drawing wires-stranding conductor bunches-lapping an isolating layer-extruding an insulating layer-radiation cross-linking the insulating layer-twisting insulating cores into cables, filling gaps and lapping the insulating layer-extruding an outer sheath-radiation cross-linking the outer sheath-checking finished products-packaging and storing finished cables. The cable produced by the manufacturing method has low-temperature resistance, twist resistance, ozone-corrosion resistance, light aging resistance, oil resistance, sea water resistance and mechanical and physical performances better than the performances of EPR-insulating chlorinated polyethylene-sheath wind energy cable.

Description

Technical field: [0001] The invention relates to the technical field of special cables, in particular to a method for manufacturing special cables suitable for wind power generation equipment. Background technique: [0002] In August 2007, the National Development and Reform Commission formulated the "Medium and Long-term Development Plan for Renewable Energy", which included wind power generation as one of the key development goals. In 2007, the newly installed wind power capacity was 3.28 million kilowatts, becoming the fastest growing wind power after the United States and Spain. One of the fastest markets. By the end of 2007, my country had installed 6,458 wind turbines, with an installed capacity of 5.89 million kilowatts, ranking fifth in the world. China is rich in wind energy resources. The total wind energy reserves that can be developed in my country are about 4.35 billion kilowatts, of which the wind energy reserves on land that can be developed and utilized are ...
