Embodiment Construction

[0011] 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.

[0012] Such as figure 1 As shown, a fluoroplastic insulated silicone rubber sheathed high temperature resistant power cable includes several mutually twisted cable cores, the cable core includes a conductor 2, and the outer part of the conductor 2 is extruded with a fluoroplastic insulating layer 3. The exterior of the fluoroplastic insulation layer 3 is wrapped with a metal armor layer 1, and the exterior of the metal armor layer 1 is wrapped with a soft polyvinyl chloride buffer layer 7 for buffering. The soft polyvinyl chloride The exterior of the vinyl chloride buffer layer 7 is wrapped with a shielding layer 6, and the exterior of the shielding layer 6 is extruded with a silicone rubber sheath 5. The soft polyvinyl chloride buffer layer 7 is provided with several wires for isolatin...

Abstract

The invention relates to the field of cables, in particular to a fluoroplastic insulating silicone rubber sheathed high-temperature-resistant power cable. The fluoroplastic insulating silicone rubbersheathed high-temperature-resistant power cable comprises a plurality of mutually twisted cable cores, wherein each cable core comprises a conductor, each conductor is extruded with a fluoroplastic insulating layer, each fluoroplastic insulating layer is wrapped with a metal armor layer, the metal armor layers are wrapped with a flexible polyvinyl chloride buffer layer used for buffering, the flexible polyvinyl chloride buffer layer is wrapped with a shielding layer, and the shielding layer is extruded with a silicone rubber sheath. According to the fluoroplastic insulating silicone rubber sheathed high-temperature-resistant power cable, the fluoroplastic is used as the insulating layer, thus the cable can resist high temperature and the cable life is prolonged; the silicone rubber is usedas the sheath, thus the cable can resist heat and cold, and water is prevented from penetrating into the cable to affect cable transmission; a resin block is used as a material for isolating the cable cores, and the resin block is low in price, has a certain degree of flexibility, and can reduce damages to the cable by an external mechanical force.

Description

technical field [0001] The invention relates to the field of cables, in particular to a high-temperature-resistant power cable with a fluoroplastic insulated silicone rubber sheath. Background technique [0002] With the rapid development of China's economy, the cable has gained a great living space, but many problems will be encountered in the production, such as the life of the cable is reduced due to the lack of high temperature resistance, which causes the resource to be consumed and the cost to rise. In order to reduce the cost, Improving cable life is very important. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a fluoroplastic insulated silicone rubber sheathed high temperature resistant power cable. [0004] A fluoroplastic insulated silicone rubber sheathed high-temperature resistant power cable, comprising several cable cores twisted with each other, the cable cores include conductors, and the outside of ...
