Abstract

The invention discloses a cable with high current-carrying capacity. The cable provided by the invention comprises more than one conductor and a sheath (5), wherein the more than one conductor is enamel-cover stranded conductor (1); and an insulating layer (2) is arranged on the surface of the more than one enamel-cover stranded conductor (1) and covers the surface. By adopting the technical scheme, under the condition that the cross-sectional area of the conductors is not increased, the surface area of the conductors is increased; and the conductors are decomposed into a plurality of independent parts and each independent part of the conductors has an insulation system, thus increasing the surface area of the conductors actually, reducing skin effects, improving the current-carrying capacity, keeping the material consumption unchanged, and being easy to realize technically.

Description

technical field [0001] The invention belongs to the technical field of power cable structure, in particular, the invention relates to a cable with a large carrying capacity. Background technique [0002] With the rapid development of the national economy, the demand for power is increasing, which puts forward higher requirements for the ability of cables to transmit electric energy, and needs to transmit more electric energy with a smaller cross-section. However, the traditional cable is affected by the skin effect of the conductor, and the carrying capacity is limited. The skin effect of the cable means that the electric energy is only transmitted on the surface of the conductor. In general, it is necessary to increase the current-carrying capacity of the cable by increasing the cross-section of the conductor to increase the current-carrying capacity. [0003] Increasing the cross-section of the conductor requires an increase in the amount of conductor material used, which...
