The heat-shrinkable tube uses, in particular for insulation and marking of wires and also for providing additional protective layer. T-shirt shrink is applied to the cable, and is exposed to high temperature, causing their shrinkage and exact matching of the shape of the cable. In Botland store you will find heat shrinkable cable in multiple colors and sizes
This ser consists of 4 types of heat shrink solder connectors. The set includes the connectors with a diameter of 8 mm, 5 mm, 3 mm and 2 mm. Connectors shrink under the influence of heat. The set is enclosed in a small container.
Cable heat shrink used to insulate electrical wires and connections between wires, increasing the isolation and marking of the cables (there are between other tubes, red, black, blue or yellow-green) and create a wiring harness. They can also be used for the connection, protection from corrosion or marking elements not having contact with electricity, e.g., wires, shafts, tubes, rods, sticks or cone tools.
Heat shrink tubing should be primarily matched to the cable diameter. Of course, you should take into account the shrinkage of the bandage: typically it is about 2:1, which means that tube shrink film twice will reduce its diameter when heated (but in the market there are even versions with shrinkage 6:1). T-shirts must be resistant to extreme temperatures - at least between -30°C and +120°C (the minimum temperature of welding of the majority of such products), and more is better. Due to the fact that will not be damaged during welding on the wire and during the subsequent work. Heat shrink tubing needs to be durable - they weren't supposed to damage, flexing, and stretching, of course, in the manufacturer's range. Also pay attention to the value of puncture strength, electric (introduced in kilowoltach per millimeter, shall be not less than 15 kV/mm). If you want to use the tubing for labeling cables, be aware of choosing the right colors. Note also to choose t-shirts shrink, do not cause corrosion of the wires (especially the copper) and do not contain toxic substances such as lead or mercury.
It is very important not to exceed the manufacturer's specified operating temperature as during welding of the tube on the cable and during subsequent operation. Otherwise the bandage may be damaged, and with a significant excess of permissible limits also destroy underneath the cable. And storing bracelets in too low a temperature (especially after mounting on the cable) can lead to the formation of microcracks and, consequently, to weaken the strength of the cover. This applies particularly to products of lower quality - because of this, you should choose t-shirts shrink from a trusted source, which has better features and utilities. You should not stretch the tubing more than the values specified by the manufacturer, as this may lead to reduced material strength and loss of useful properties (e.g., strength puncture electric). Bandage shrink film will always be appropriately described by the manufacturer.
