CWH2-220V constant power heating cable details
When the temperature rises, the conductive plastic undergoes micro-molecular expansion, and the carbon particles gradually separate, causing circuit interruption and resistance increase, which automatically reduces power output. During the heating process, the number of internal semiconductor channels of the polymer material undergoes a surprising positive temperature coefficient (PTC effect) change, and has a special molecular memory ability, and this memory response is strong. The power is mainly controlled by the heat transfer process, automatically adjusting the output power with the temperature of the heated system, while traditional constant power heaters do not have this function. Self-limiting electric heating tape is a kind of electric heat tracing compensation device with unlimited production length and parallel conductors. Its structure is simple, flat and smooth in shape, with certain flexibility, and can be laid flat, wound arbitrarily, with a wide range of applications. For installation, commissioning and operation, especially in chemical plant zone 1 and oil wellhead explosion-proof places, installation should be carried out in accordance with the relevant provisions of the "Electrical Installation Engineering and Acceptance Regulations" and "Explosion-proof and Fire-proof Regulations".
Yangzhou Darui Electric Heating Material Co., Ltd. is a professional heating cable manufacturer, providing you with detailed CWH2-220V constant power type heating cable technical solutions.
Electric heat tracing products can be widely used in pipelines, pumps, valves, tanks and vessel volumes in industries such as petroleum, chemical, electric power, medicine, machinery, food, and shipping for heat tracing, insulation, anti-freezing and anti-condensation. It is the most advanced and effective method for maintaining process temperature in liquid pipelines and storage medium tanks. Construction temperature: minimum -40°C. Thermal stability: after 1000 on-off cycles for 22 consecutive days, the heating tape heat output remains above 90%. Electric heat tracing products have all-weather protection capabilities, but during installation, the system should not accumulate rain and snow. Under this premise, the system should be easy to maintain, neat and beautiful. Electric heating tape is composed of nano-conductive carbon particles and two parallel busbars plus an insulating layer. Due to this parallel structure, all self-limiting electric heating tapes can be cut to any length on site, connected using two-way or three-way junction boxes.

Electric heat tracing devices are simple, heat evenly, and can be remotely controlled and automated. The heat tracing has explosion-proof, all-weather working performance, high reliability, and long service life.
CWH2-220V constant power type electric heating tape
Classification by protective layer: flame retardant basic type-J, shielded type-P, protective type-PF, anti-corrosion type-f(46/16)PF. The company produces electric heating tapes and junction boxes, all of which are increased safety explosion-proof electrical products. After correct installation, they can reach the "ExeIIT4" explosion-proof level, suitable for use in factory zone II explosive gas mixtures of temperature groups "T1~T3".
The core of the tape is a very complex polymer composite, composed of a variety of materials and conductive media, extruded after specific chemical changes and physical treatment, forming a continuously parallel heating element between two parallel wires. When the temperature becomes cold, the plastic returns to a micro-molecular contraction state, the carbon particles connect accordingly, forming a circuit, and the heating tape power automatically rises again.
