The excellent insulation of the two contacts is a guarantee of long-term electrical wiring, in addition to high security. Therefore, an insulating tape is one of those materials that are always at hand by an electrician. But it is losing ground gradually to reduce the tubes, which in many technical characteristics are superior to the first. Then, we discover what heat contraction the cables have (the dimensions of the materials that are manufactured and how they are installed).
To begin with, the main property of heat shrink tubing (TUT) is to reduce its size under the influence of high temperatures. That is to say, place it on the contact of two cables, and it is exposed to the heat, the tube diminishes in size immediately, and it is firmly adjusted electrical connection. How can I cause a temperature? The best option is a special hairdryer, which is used for this operation. If there is not one, you can use a lit candle, a lighter, matches, etc. That is, the flame of an open fire is adequate for this. But consider the fact that contact with fire is contraindicated, and overheating the tube will not lead to anything good. The material will be covered with bubbles, harden, and crack quickly.
First. Before installing the heat shrink cable accessories:
1. Before installing the heat shrink cable accessories, first, we must verify if the fixtures of heat shrinkable cables used are installed correctly in the required cables.
2. Check the quality of the heat shrink cable accessories and whether the heat shrinkable cable accessories are complete.
3. Before installation, we must verify if the tools are perfect, if they are familiar with all types of devices, and must install themselves strictly by the instructions.
4. The installation of heat shrink cable accessories is the same professional and needs professional personnel with experience to operate.
5. Before installing the heat shrink cable accessories, the operator must carefully and carefully read the installation workbook, so that the actual operation can be performed.
Two. During the installation of heat shrink cable accessories:
1. First, the cable should be cleaned to make sure there is no dust or stains on the table surface.
2. Do not overstress the cable’s semi-guiding layer to avoid internal insulation.
3. The installation of heat shrink cable accessories is prohibited when damage to the cable sheath and insulation, the cable accessories and metal parts are in contact should be polished carefully, polished words may have beards or other metal components, installed directly will lead to cracking of the heat shrinkable accessories.
4. Take off the housing preparation, use a clean towel to clean the insulating layer of the cable.
