Fiber heating flexible cable

Abstract

The invention discloses a fiber heating flexible cable, comprising conductors which are formed by stranding a plurality of copper wires. An EP rubber thin film layer tightly wraps on the periphery of an acrylonitrile-styrene-butadiene copolymer insulating layer. The periphery of the EP rubber thin film layer is tightly wrapped with a layer of semiconductive nylon tape. An outer layer of the semiconductive nylon tape is provided with a nickel-plated high strength fiber heating wire. An insulating layer is wrapped outside the high strength fiber heating wire. Finally, a layer of fluorinated ethylene-propylene is extruded outside the insulating layer. First, the conductors of the cable are stranded by relatively soft copper wires, the diameter is not large, and deformability is relatively high. In addition, the acrylonitrile-styrene-butadiene copolymer insulating layer and the EP rubber thin film layer belong to relative flexible organic materials, and any deformation would not influence the materials and damage the materials. Moreover, the nickel-plated high strength fibers and the semiconductive nylon tape can give out heat and stop heat from being lost, thereby greatly improving utilization rate of heat energy.

Description

technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to a fiber heating flexible cable. Background technique [0002] As we all know, most of the electric heaters in the prior art use nickel-chromium alloy, iron-chromium-aluminum alloy and copper alloy materials as electric heating bodies. Due to the inherent characteristics of these electric heater materials, there are many deficiencies in use. For example, although electric heaters made of these materials have certain plasticity and bendability, the surface of the electric heater is easy to oxidize during heating and use. The local current is too large, the temperature is too high and it is blown; at the same time, there is visible light in the electric heating process, so the thermal efficiency is low, and they are difficult to make electric heating elements of any shape, and they do not have long-term resistance and random bending performance. to its scope of ap...
