What are the details of the installation of the electric tropics when they are installed?

Date:2017-11-08 Author:Yicheng network Click:

With the development of electric tracing technology, more and more users are using electric tracing products for pipes and tanks. However, due to the fact that there are not enough details about the electric companion zone when installing the electric companion products, it will cause a lot of problems when installing the electric companion zone. What details should we pay attention to when installing the electric tracing product?

First, it should be noted that the cable products in handling installation do not knot twisted, many people may feel that the cable bending toughness is good, play song is also does not have what problem, this idea is wrong, because it is very easy to cause the damaged insulation cable, in the right way when the installation cable should be handled with care.

Secondly, in the fixed cable is fixed, a lot of people used to bring a metal bar, this approach is not desirable, because the working principle of the cable is thermal expansion and contraction, if the metal bar bring fixed cable, cable insulation layer can be damaged, should be special fixed rubber cable has fixed, if the use of non metal bar to bring fixed words, need to set aside the necessary activities space.

In addition, the sharp corners and burrs on pipes are also easy to be ignored, so we can apply a layer of anti-corrosion and anti rust coating on them. Only by paying attention to details, can we make the electric heating zone play the best performance and keep heat insulation for pipelines.

The choice of the electric cable structure is based on the installation environment and conditions. 1) choose shielding products on the plastic or surface and the unreliable container and pipeline. 2) in the inflammable and explosive area, or the medium in the tube is flammable and explosive medium, the shielding type explosion-proof electric heat tracing product should be selected. 3) protective products should be used if the medium is corrosive in the pipeline, or chemicals that may contact the corrosion shielding layer of the cable.

Other matters:

The connection section of electric power supply in the tropical zone is greater than that of the conductor section of the hot cable.

The fuse and air switch should be moderately selected and should be considered to be larger than the full line starting current.

A special power junction box, intermediate junction box and terminal and other special accessories must be used in flammable and explosive areas.

According to the power supply capacity, voltage and power grid balance state, single phase power supply or three-phase power supply and voltage level are adopted.

Whether the surrounding environment of the pipe is easy to install cable, determine the electric companion tropical, use straight line laying or spiral laying.
