Abstract

The invention discloses a wind-energy power cable with high resistance to twisting. The wind-power cable comprises two power cables and extruded sheaths arranged outside the power cables respectively,the inner wall of each extruded sheath sleeves a plastic tube, the power cable is positioned in the plastic tube and makes contact with the inner wall of the plastic tube, the sidewall of one power cable is provided with a channel section, the sidewall of the other power cable is provided with a copper rod which matches the channel section, the ends, corresponding to each other, of the two extruded sheaths sleeve first and second annular blocks respectively, four cavities are formed in the first annular block symmetrically, and in each cavity, a first bearing is in rotational connection witha corresponding cylinder. The wind-energy power cable is convenient to operate, the internal power cable bodies can be prevented from twisting with the extruded sheaths, the power cable has a higher resistance to twisting, the power cables can be connected conveniently and rapidly, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wind energy and electric power, in particular to a wind energy electric cable with good torsion resistance. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, power station lead lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electric energy in the main line of the power system, including 1-500KV and above various voltage levels and various insulated power cables. [0003] After searching, the Chinese patent authorization number is CN104051069A, which discloses a cold-resistant torsion-resistant flame-retardant wind energy power cable, which consists of a number of aramid wire co...
