From what aspects can we see that the quality of electric heating cable is good

During the cold winter months, many pipes require heating. Traditional steam heating suffers from temperature fluctuations and a short service life. Electric heating cables have become the dominant product in the heating industry, but how can one choose a high-quality, reliable cable? The selection criteria for electric heating cables are primarily determined by the following three factors.

The starting current of an electric heating cable. This refers to the peak current generated when the cable is connected to the power supply. It plays a decisive role in the cable's quality and is a key parameter reflecting the manufacturing process. A high starting current shortens the cable's usable lifespan, shortens its service life, and poses a significant safety hazard. Therefore, when purchasing electric heating cables, choose cables with a low starting current.

The quality of the cable's core conductor directly affects its quality. Tinned copper wire is typically used, and the quality of the copper wire affects its insulation performance. The cable's conductor is typically composed of seven twisted strands of tinned copper wire. The amount of conductor used directly affects the cable's cost. If the conductor is too thin, it will overheat, which, over time, will shorten the service life of the heating cable and even lead to serious consequences.

PTC Irradiation Process for Electric Heating Cables. Irradiation of the core ribbon stabilizes its performance, imparting a memory function to the core ribbon's electrical properties, thereby maintaining stable temperature limits and extending its service life. Currently, high-energy electron irradiation cross-linking is the most commonly used method. The appropriate irradiation dose is determined based on the PTC material system, but the dose rate should not be too high. The linear speed during irradiation must also be uniform, and the operating tension and friction must be controlled appropriately.

High-quality electric heating cables have uniform internal layers. Furthermore, the outer surface should also have uniform thickness, good toughness and strength, and be resistant to breakage and tearing, ensuring excellent insulation. Our company's electric heating cables offer excellent temperature resistance, uniform heating, easy installation and maintenance, energy conservation and environmental protection, and a long service life. They are widely used in various industries, including the petroleum, fire protection, and power plants, and their quality is trustworthy.
