Most often, water-blocking tapes are used to protect optical fiber and power cables from various kinds of moisture. It is a kind of barrier that prevents the wiring from shorting and spoiling. However, the main advantage of insulating films is their lightness. A cable insulated with such tape is thinner and lighter than the same model of cable with rubber insulation. They are divided into one-sided and two-sided models. In addition, the F4 tape has excellent resistance to organic and mineral acids.
PMF Film
Among the huge number of water-blocking films, special attention should be paid to insulation from PMF. It allows the use of insulated cable at very high temperatures, while its basic properties remain unchanged. As a rule, the operating temperature varies from ninety minutes to plus two hundred and seventy degrees Celsius. This type of film is often found in machines that are forced to operate under low pressure conditions (about six gPa).
The main advantages of insulating tapes:
- Providing an easy indication of the polarity is achieved through the use of certain conductors, most often nylon and its various analogues, which are color-coded;
- Even if the film stays in the water for a long time, it will not affect its condition in any way. However, the most important thing is that it does not undergo wear, abrasion and other damage that can be caused by various chemicals.;
- These water-blocking tapes were developed specifically for operation at extremely high and low temperatures. They perfectly cope with their task, which is an advantage over other models.
Nylon insulation tapes
They are made of polyimide, which is a dielectric and has excellent temperature properties, which makes the nylon film one of the most in demand on the market. The strength and durability of this material allows it to be used on top of various conductors. Nylon insulation is often used in electrical engineering. For this purpose, such varieties of nylon are used:
- Literoid;
- Electric cardboard;
- Fiber;
Fiber is the most effective. It is treated with weak acids, as a result of which it becomes quite hard and durable. Its only drawback is its increased hygroscopicity. Open https://slin-go.ru and try popular casino slots and live games.
