Abstract
The invention discloses an anti-torsion signal control cable for wind power generating equipment, belonging to the technical field of electric wires and cables. The anti-torsion signal control cable comprises a cable core, a braiding layer, an isolation layer and an outer sheath, wherein the cable core comprises a lead and an inner sheath arranged outside the lead, the braiding layer, the isolation layer and the outer sheath are sequentially arranged outside the cable core, the lead comprises a group of inner-layer leads and a group of outer-layer leads, the outer-layer leads are distributed around the circumferential direction of the inner-layer leads so as to surround the inner-layer leads, and in addition, the outer-layer leads and the inner-layer leads are stranded, wherein the inner-layer leads are stranded in the Z direction, the outer-layer leads are stranded in the S direction, and the outer sheath is made of polyurethane. The anti-torsion signal control cable has the advantages of effectively inhibiting relative slide between leads in a frequent cable torsion process and avoiding short circuits or open circuits triggered by damages to the isolation layer; and the outer sheath is made of the polyurethane so that the wear resistance, the weather resistance and the torsion resistance are improved.
Description
technical field [0001] The invention belongs to the technical field of electric wires and cables, and in particular relates to an anti-torsion signal control cable for wind power generation equipment, which is used as a signal control connection for wind power generation equipment. Background technique [0002] The industry usually refers to the signal control connection lines of wind power generation equipment and the cables leading out the electric energy of wind power generators as wind energy cables or wind power cables. Due to the use characteristics of wind turbines, that is, they are in the natural environment for many years, the requirements for wind energy cables are extremely strict, mainly manifested in the characteristics of resistance to repeated torsion (also known as twisting) and tensile strength. [0003] Wind energy cables can be found in a large number of published Chinese patent documents. The new type of wind power generator cable recommended by the auth...
