Classified by cable use
Ordinary type heating cable: This is a two-core structure heating cable. It is composed of two parallel metal wires coated with polymer PTC material and flame retardant sheath material or metal mesh and fluorine material sheath. Due to the influence of the conductor diameter and the voltage drop along the length, the connection length of this cable generally does not exceed 200 meters.
Ultra-long distance heating cable
Ultra-long distance heating cable
Extra-long heating cable: This is a five-core or six-core heating cable with a special structure. In addition to two parallel wires wrapped in polymer PTC material, 3-5 metal wires with insulating sheath and metal armor are arranged in the same direction. Used to transmit electrical energy. This special structure makes the maximum continuous use length of the cable not exceed 1100 meters, so it can be applied to the heat tracing of oil and gas transmission channels and the downhole heat tracing of oil fields.

Safety heating cable: This is a three-core heating cable. In the cable, a separate monitoring wire is placed along the length of the flame retardant sheath. The monitoring wire can transmit the abnormal change of output power, overcurrent situation, local damage and other information along the line to the central control room in time, which is convenient to understand the heating situation along the line in time and ensure the safe and reliable operation of the cable.
