A glass fiber flexible electric heating cable

Abstract

The invention provides a glass fiber flexible electric heating cable, which includes two symmetrically distributed busbars, a wire insulation layer sleeved on the busbars, a transparent sheath sleeved on the two wire insulation layers, and a transparent sheath sleeved on the transparent sheath. The heating wire on the cover, one end of the heating wire is connected with a conductive connection point, and the opposite side of the two wire insulation layers is in contact with the same clamping strip, the clamping strip includes a plurality of insulating blocks connected end to end, and the insulating A plurality of rotating shafts are plugged in the center of the block, and the two ends of the rotating shafts are respectively connected to two insulating layers of wires. The invention overcomes the deficiencies of the prior art, has a reasonable design and a compact structure, and solves the problems that the existing electric heating cables have low flexibility and are not equipped with a good temperature control device, so that the electric heating cables are damaged due to excessive temperature. Various methods improve the flexibility of the electric heating cable, which is more suitable for arrangement in curved pipes. At the same time, a temperature control device is added to improve the practicability of the electric heating cable.

Description

technical field [0001] The invention relates to the technical field of flexible electric heating cable equipment, in particular to a glass fiber flexible electric heating cable. Background technique [0002] Electric heating cable is composed of conductive polymer and two parallel metal wires and insulating sheath. [0003] Due to the long thermal stability time of the electric heating cable, and the advantages of high thermal efficiency, energy saving, convenient installation, no pollution, long service life and automatic control, it is often used in liquid pipelines to prevent liquid pipelines from freezing in winter and affecting their use. [0004] During the installation process, due to the bending phenomenon of the pipe, the general electric heating cable is not very soft. After bending for a long time, it is easy to cause damage to the electric heating cable, causing a great safety hazard; at the same time, the general electric heating cable on the market The heating...
