Embodiment Construction

[0015] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0016] Such as figure 1 As shown, a fluorine plastic insulated high temperature resistant power cable includes a number of fan-shaped cores 1 evenly distributed, and the center of the distribution of the fan-shaped cores 1 is extruded with a circle between adjacent fan-shaped cores 1 The wire core 2, the outside of the fan-shaped wire core 1 and the circular wire core 2 are covered with an inner lining layer 3, a metal armor 4, a tape layer 5, and an outer sheath 6 in sequence from the inside to the outside, and the inner lining layer The inside of 3 is provided with filler 7, and described filler is PP filler.

[0017] Based on the above, it can be seen that this installation structure can ensure that when the number of wire cores wrapped inside the cable is large, it can also achieve...

Abstract

The invention relates to a fluoroplastic insulated and high-temperature-resistant power cable, which comprises a plurality of evenly distributed and fan-shaped wire cores. Circular wire cores are extruded at the distribution center of the plurality of fan-shaped wire cores and between adjacent fan-shaped wire cores, respectively. An inner lining layer, a metal armoring layer, a wrapping tape layerand an outer sheath are sequentially wrapped outside the fan-shaped wire cores and the circular wire cores from inside to outside. A filler is arranged inside the inner lining layer. Each fan-shapedwire core comprises a fan-shaped conductor and a first insulating layer. Each circular wire core comprises a circular conductor and a second insulating layer. The fan-shaped conductor and the circularconductor are all formed by twisting copper wires. The first insulating layer and the second insulating layer are made of cross-linked polyethylene. The inner lining layer is made of ceramic fireproof polyolefin material. According to the invention, the power cable is prepared through assembling more wire cores, and the power cable is high in stability. The surface of the power cable is effectively prevented from being damaged. The occurrence of potential safety hazards is reduced. The personal safety is guaranteed. The power cable is fire-resistant and high temperature-resistant. The long-time operation of the cable is achieved, and the service life of the power cable is greatly prolonged.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a fluoroplastic insulated high temperature resistant power cable. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. When laying daily cables, it is easy to damage the cable skin, causing potential safety hazards and endangering the lives and health of workers. Due to the strong transmission power of power cables, it is easy to cause fire hazards, resulting in damage to the inner core of the cable. Contents of the invention [0003] In order to avoid and solve the above technical problems, the present invention proposes a fluoroplastic insulated high tempe...
