Description

Technical Field

[0001] The utility model relates to the technical field of control cables, in particular to a cold-resistant polyethylene insulated control cable. Background Art

[0002] Control cables are PVC insulated and PVC sheathed control cables suitable for industrial and mining enterprises, energy and transportation departments, and for control and protection lines with AC rated voltages below 450 / 750 volts. The use areas and laying times of control cables on the market are currently subject to seasonal restrictions. When used in cold areas, control cables will crack due to low temperatures, posing a huge safety hazard. Therefore, a cold-resistant polyethylene insulated control cable is required.

[0003] Existing technology CN208796711U, this patent proposes a cold-resistant polyethylene insulated control cable. When the control cable is used in a low-temperature environment, it can be energized and heated by the electric heating component and the heating tape, providing external supplementary energy for the control cable, so that the control cable has better cold resistance; the far-infrared coating can convert the energy generated by the heating into far-infrared rays, and the far-infrared rays with stronger penetrating power can evenly heat the other layers of materials outside the inner layer of the control cable, thereby achieving better cold resistance.

[0004] When using existing technology, a heating component is usually used to heat the cable to provide it with better cold resistance. However, when using it, direct heating of the cable may cause water accumulation due to the large temperature difference between the cable and the outside world, which may cause the cable to short-circuit and create a safety hazard.

The waterproof layer can prevent the internal cable core from coming into contact with water when used in a humid environment, thereby causing a short circuit. The flame-retardant layer can prevent the cable core from being burned out in the first place during combustion, thus saving longer maintenance time and avoiding greater losses.

The cold-resistant polyethylene insulated control cable is installed with a wear-resistant layer 107, a waterproof layer 108 and a flame retardant layer 109. Since the cable is often laid outside or underground for use when in use, the wear-resistant layer 107 can greatly enhance the wear resistance of the device, so that it can be used for a longer time.
