Low installation and operating cost of electric heat tracing insulation, fast heating start, uniform pipeline temperature, no overheating, safe and reliable, easy maintenance, and a wide range of applications, such as solar energy pipelines, fire-fighting pipelines, air-conditioning water pipelines, industrial water pipelines, oil and natural gas pipelines And all kinds of tank containers are very popular antifreeze and heat preservation products in winter.

     When using electric heating cables for heat preservation, many users are not very familiar with the wiring method. Taking the protective self-limiting temperature electric heating cable as an example, the electric heating cable wiring is divided into a head end and a tail end. The ends need to be sealed.

      The first-end wiring of the electric heating cable is to strip off the two conductors of the heating cable, connect the live and neutral wires of the power plug to the two wires, and use heat shrink tubing for overall sealing. The tail end seal can be sealed with a tail end junction box. The materials required for the installation of the heating cable end can be placed in the junction box. The core wire must not be directly connected or heat shrinkable with heat shrinkable tubing.

      It is necessary to pay attention to the waterproof and moisture-proof sealing treatment when using the power supply or the terminal connection. At the same time, it is also to prevent the wires from being merged or the wires are exposed.
