The heating cable of electric heat tracing is a flat long strip. The quality of its conductive core wire directly affects the performance of the heat tracing cable.Heating Cable. Usually, the conductive core wire is made of tinned copper wire. The quality of the copper wire directly affects the insulation effect. Of course, the quality of the conductor is controlled by the manufacturer. How can consumers distinguish the quality of the conductor? The conductor of the heat tracing heating cable is generally composed of 7 strands of tinned copper wire twisted together. The amount of conductor used directly affects the cost price of the heat tracing heating cable. Some manufacturers, in order to reduce costs, reduce the cross-sectional area of copper. Based on years of customer feedback, the manufacturer has made a more reasonable design by increasing the conductor cross-section, using a 7*0.52 (1.5 square) wire core. However, due to fierce competition in the cable industry, the mainstream heat tracing heating cable wire core on the market is still 7*0.43 (1.0 square) conductor. This type of heat tracing heating cable has a very serious drawback: the starting current is too large.
The advantage of self-regulating safe voltage electric heat tracing is fast start-up at low temperatures, uniform temperature, and each part can automatically adjust according to the temperature change of the heated part. It is easy to install, simple to maintain, has a high level of automation, and low operation and maintenance costs. It is safe, reliable, widely used, does not pollute the environment, and has a long service life.
