More recently, the use of an electric cable to heat a roof, water supply, pipeline or drain was considered something new. But today it is a common thing. Such a cable is not designed to supply current through it, but to generate heat. Increasingly, this cable is used for heating. And if demand grows, then supply increases. Therefore, many companies offer their products to consumers, competing with each other. They produce many types of cables, so the consumer's eyes can run away - which one is better to choose, so that it is suitable for its purposes and is of high quality and reliable? In this article we will help you learn how to choose a cable for heating pipes.
Resistive heating cable for heating pipes
Before To buy a product, you should consider the basic parameters by which such cables for heating differ:
You should know that there is no universal option for all occasions. In this regard, before you go to the store, you need to understand what you expect from the heating system. What will it serve for what purpose?
In general, the scope of application of such elements can be divided into three main categories:
Having defined your goal, you can learn the basic parameters.
Device of different resistance cables
In what the difference? If we talk about a resistive cable, it is sold exclusively of a certain length and has a constant power. Warming by such an element should be careful and uniform. The big disadvantage is that it can burn out due to overheating. Therefore, it is much cheaper than self-regulating. The fact that the resistive cable often burns out has led to the fact that it is practically not used for heating pipes. Moreover, the emergence of a self-regulating heat cable has simplified the task of many consumers.
The principle of operation of the self-regulating heating element
The heating cable is self-regulating though it costs much more, but still replaced in the market resistive. And this is not surprising, because it is more reliable, economical in electricity consumption and easy to use. As you can see, the advantage is clear. Nevertheless, who will be the favorite, is a purely personal matter.
Self-regulating cable with and without braid
Heating cables are produced with and without braiding. The difference between them is great. The braided thermal cable is the heating cable itself and only one external insulation. It can be said, an economy option.
The self-regulating cable with braid (or shield) includes tinned copper wires, which serve as braid and one more additional insulation. The presence of such materials makes the cable:
Such a cable is more expensive, but its price justifies the quality.
Different material of external insulation
Models are considered as standard insulation made of polyolefin. Such you can find in any store. They are suitable for the average user, whose goal is a standard heating water supply, defrosting of frozen pipes, sewers, roofs, etc. But there are other cases. On production, the main property of external insulation should be resistance to aggressive media, UV rays, etc.
Depending on the temperature that is emitted, the heat cable is divided into three classes:
The cable indicates the power
For First you need to understand that high power is not the key to success. Since if you buy a heat cable with a power greater than necessary, you simply throw your money away. Such a device will consume too much electricity. Because of this, you need to choose the equipment that will best meet the needs.
The cable power is adjusted based on the diameter of the pipe. The larger diameter, the more powerful cable is needed. It also takes into account which layer of insulation will be on the pipe. The thicker it is, the less loss, and, accordingly, less consumption. Consider which cable to choose for pipes with different diameters:
Now you can choose a cable that is right for you, and will also serve a specific purpose. This will help you not only to use it rationally, but also to save your money. Having such a baggage of knowledge, you can safely go to the store for a purchase.
