Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] Such as figure 1 and figure 2 As shown, a high-temperature-resistant cable includes a conductor 1 and an outer sheath 6. The conductor 1 is extruded with a layer of high-temperature-resistant insulating layer 2, and the high-temperature-resistant insulating layer 2 is wrapped with a glass fiber layer 3. The glass fiber layer 3 The outer winding mica tape layer 4 forms a cable core, and the gap between the cable core and the outer sheath 6 is provided with a high temperature resistant filler 5; the material of the high temperature resistant insulating layer 2 is polytetrafluoroethylene; the high temperature resistant filler 5 is Glass fiber filler; the outer sheath 6 is a silicone rubber sheath. The invention has excellent high temperature resistance performance, is suitable for use in high temperature environment, and reduces the influence of ...

Abstract

The invention discloses a high-temperature resistant cable which comprises a conductor and an external sheath; the conductor is wrapped with a high-temperature resistant insulating layer in an extruded manner; glass fibers are wound outside the high-temperature insulating layer; a mica tape is wound outside the glass fiber; and thus a cable core is formed; high-temperature resistant filling is arranged in the gap between the cable core and the external sheath; the material of the high-temperature resistant insulating layer is polyfluortetraethylene; the high-temperature resistant filling is glass fibers; and the external sheath is a silicon rubber sheath. The cable provided by the invention is simple in structure, convenient to process and low in cost, has excellent high-temperature performance and is suitable for being used in high-temperature environments; moreover the influence of temperature on electrical property of the cable can be reduced, so that the production can be performed normally and stably.

Description

technical field [0001] The invention relates to a cable, especially a high temperature resistant cable. Background technique [0002] With the development of science and technology, some industries have higher and higher requirements for the high temperature resistance of cables, especially the cables used in metallurgy, metal cutting and other industries have been working at high temperature for a long time, and the high temperature often affects the electrical performance of the cable.
