Heating cable self-regulating: types, prices, manufacturers

Currently, self-regulating heating cable for water pipe is quite widespread in the market. It is believed that this is the very best of modern building design. Next, learn what constitutes a self-regulating heating cable for pipes.

General information

Many are unhappy with the how much is a heating cable (self-regulating). The price of such products is indeed higher simple devices. However, it is necessary to take into account the peculiarities of this development. Then, the benefit of acquisition becomes evident.

Main product features

Heating cable (self-regulating) is very similar to a normal network cable. However, he has an ulterior motive flattened shape. First of all, it depends on the location of the major job elements. All three of them. The configuration of this cable is arranged so that the area of the heated tube obkladyvaetsja as possible. Valid device operation together with other objects, among which are the following:

1. Plastic and metal products.
2. The System "warm floor".
3. Elements for the roof.
4. The Pipeline system.

Principles of operation

Heating cable (self-regulating) is quite difficult. He gives the product the possibility of changing its own temperature. The cable consists of the following elements:

• Insulation;
• Semi-conductive self-regulating matrix;
• Copper heat-conducting veins.

Two conductors made of copper are arranged in parallel in the volume of the extruded material. The matrix is between them. Its basis is plastic or carbon powder. The matrix varies in size depending on the environment. It has the ability to control the potential difference between the conductors. Thus, there is a temperature change. The working system is in thermoplastic insulation. Copper braid is placed inside of the structure. Quite rare to see the heating cable inside the pipe. Self-adjusting wire most often lay outside. Due to this, use all its capabilities. Such products have several advantages among which are the following:

Read the instruction

Instruction is necessary because it can be easily determined by connecting self-regulating heating cable to the water pipe. As a rule, it is attached to the kit. Thanks to it you can learn about all the working parameters of the product. In addition, you should familiarize yourself with a detailed wiring diagram.

Preparation

She should proceed only after detailed acquaintance with the user manual. The developers of this heating cable has taken care to ensure that the installation can be done by everyone. It does not it puts a lot of effort. Also need to take care of all necessary work elements. In particular, we will need the following materials and tools:

1. Heating cable (self-regulating).
2. Bench tools with dielectric handles.
3. Waterproofing.
4. Scotch tape on the basis of the foil.
5. Roll insulation.
6. Plumbing tape.

Installation

Pipe paste in a spiral. This is done using tape-based foil. It is prohibited to use cloth adhesive tape.

Heating cable may be overwound in several ways:

1. Spiral.
2. Waveform.
3. Parallel along the surface. It uses one or several rows, which are arranged symmetrically.

Obtrude spiral is the most common method. Also expected to respect the same distance between the segments. Because of this the heat is evenly distributed throughout the pipeline. In addition, you need it the most a snug fit to the surface. Foil tape is wound repeatedly around the cable. This ensures its secure fit. Then should be uniformly imposed the insulating layer. All joints are densely adjusted to each other. Thus, no formation of cold bridges. Waterproofing is a mandatory element of similar design. The reliability of the heating system depends on it.

Connections

This can be used in the normal terminal. Using them connects heating cable to power. You can also use special adapters that are available for sale. First of all you need to prepare the cable. With the top insulation removed 4 see the use of specific mites. Braid of copper should be gently twisted into a ponytail. Observing extreme caution, removed about 3 cm of inner insulation. It is impossible to prevent damage to the black core of the matrix. Insulating layer (to 4 cm) should be removed from the power wires. Before connecting the bared cable conductors are fitted with heat shrinktubes. Then they are heated with a Hairdryer. Next, on top of a single wire is placed a similar tube of greater diameter. Then it should be moved to the side. Terminals are installed on top of it. For crimping we use specialized tools.

Cost

At present, to acquire self-regulating heating cable quite easily. On the market there are models with different parameters and characteristics. You can buy products from different manufacturers. Now very popular model, Eltherm and Thermon. The price of RC model starts from 70 rubles. At the same time, the average cost per meter of heating cable – from $ 3. Certain models can cost much more. It is best to choose products that relate to the middle price category.

How not to be mistaken with a choice?

All depends on the location of the stacking cable. This factor should be the base for the calculation of the required capacity of the product. For example, if the cable is to be laid on top, then it will take 17 W/m. If the cord is inside the pipe, it is enough and 10 W/m Also should pay attention to the relay. In this case, it is best to give preference to the representatives of the TSTAB or TR-35M.

Rules of operation

In most cases the relay there is a led light bulb. She lights up when system is switched off or starts to work. It is very important to check the correct operation of the led signals after you change temperature parameters.
