Power electric cable resistant to alternating working condition

Abstract

The invention provides a power electric cable resistant to an alternating working condition. The power electric cable comprises multiple control cores and power cores, and an insulating layer and a shielding layer are sequentially arranged outside the control cores; an insulating layer and a shielding layer are sequentially arranged outside the power cores; a rubber filling layer is filled betweenevery two of all the control cores, between the power cores and between the control cores and the power cores respectively; and a fireproof belt, a fiber braided layer and an outer sheath are sequentially arranged outside a cable assembly composed of the control cores and the power cores. By adopting the scheme, cables have enough flexibility, namely cables have enough toughness while having enough softness, thereby guaranteeing that the electric cable can not be bent for a relatively small angle; meanwhile, the power electric cable provided by the invention integrates the power cores and thecontrol cores into a whole, so that quantity of the cables is reduced.

Description

technical field [0001] The invention relates to the field of cables, in particular to a power cable resistant to alternating working conditions. Background technique [0002] With the development of the RV reducer, the shape and load-bearing capacity of the power mechanical arm driven by electricity are gradually increasing. Existing power machines, such as manipulators, usually adopt the scheme of separately arranging the power cables and control cables, resulting in many cables, and the power machines are under alternating working conditions, and the control cables and power cables are easily caused by friction and alternating current. Damage due to changing working conditions affects the service life of the robotic arm, and it is difficult for the cable to achieve an optimal balance between sufficient mechanical strength and flexibility. Since power machinery usually requires high control accuracy, it is necessary to ensure that the control cables have sufficient anti-sh...

AI Technical Summary

Problems solved by technology

The problem is that the metal braided mesh has weak anti-shielding ability due to the gap, and the metal belt has stronger anti-shielding ability, but the ability to resist repeated deformation in alternating working conditions is weak.

Graphene conductive tape is used to improve the shielding effect, but the cost of graphene conductive tape is very high due to the immature production process

At least there are no mass-produced products on the market
