[0003] In addition, the power cable plays the role of "backbone" in the process of power transmission, power distribution and conduction. However, in the traditional sense of the power cable, the insulation layer of the conductor is mostly single layer, which increases the danger to a certain extent. Because the conductor It is the core of the entire power cable. Once leakage occurs, it will not only cause energy loss, but also cause serious accidents. At the same time, most of the power cable sheaths on the market use single-layer sheaths. Its safety factor is not high, its wear resistance does not meet the requirements, and it cannot be applied to some harsh high-temperature environments, which needs to be improved

Embodiment Construction
[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0016] Such as figure 1 The shown cable structure includes a cable main body 1, the cable main body 1 includes an outer wrapping layer 11 and an inner core 12, and the outer wrapping layer 11 includes an outermost refractory layer 111 and an innermost layer and an inner core 12 The surrounding layer 112 is in contact with the surrounding layer 112. A bushing 114 is arranged on the surrounding layer 112. An intermediate filling material 113 is arranged between the bushing 114 and the refractory layer 111. The inner core 12 is penetrated in the surrounding layer 112. and isolated from each other.

Abstract
The invention discloses a cable structure comprising a cable body; the cable body comprises an outer wrapping layer and inner cores; the outer wrapping layer comprises the most outside fireproof layer and the most inner surrounding layer making contacts with the inner cores; the surrounding layer is provided with a bushing; a filling material is arranged between the bushing and the fireproof layer; the inner cores penetrate the surrounding layer and are mutually isolated; the surrounding layer can well separate the cable inner cores, thus preventing short circuit phenomenon caused by bumping when the inner cores are aged, increasing safety factors, improving cable usage duration, and saving cost.
Description
technical field [0001] The invention relates to the technical field of electric equipment, and relates to a cable structure. Background technique [0002] The cable consists of one or more insulated and wrapped conductors, which are then wrapped with a hard substance made of metal or rubber. Power cables are used to transmit and distribute electric energy. They are generally used in urban underground power grids, power plant lead-out lines, and power supply inside factories. Cables account for a large proportion of power lines and play a role in transmission and distribution when used. The role of high-power electric energy. Therefore, when making cables, we need good manufacturing methods and optimized structures to ensure the smooth transmission of electric energy and power. [0003] In addition, the power cable plays the role of "backbone" in the process of power transmission, power distribution, and conduction. However, in the traditional sense of the power cable, the ...
