self-regulating heating cable out jacket to protect the core zone. Among them, according to the environmental environment, such as humidity, danger, corrosion, and high temperature areas, they have their own requirements for electrical tropical external care materials. For example, in an environment with steam blowouts, if you do not use a high -temperature -resistant hematic temperature -limited temperature with a tropical tropical, it will cause an accident because it cannot resist high temperature, causing accidents. It can be seen that the protective cover material is a very important part of the tropical restriction with the tropical part of the temperature, and it is also an important basis for identifying the quality of the electricity with electricity. So what are the characteristics of self -limiting temperature with tropical products? details as follows:

       Surface character

       self-regulating heating cable with the tropical surface of the temperature should be smooth and oil -free. Under high temperature work, the taste of pungent plastic), non -burrs (affecting the protection of the tropical cover cover and the contact surface of the pipeline to avoid the surface of the heated object container caused by this phenomenon Bad "ash).

       Heat resistance and anti -aging

       For the outer condom outside the tropical metal woven layer of explosion -proof electricity with an explosion -proof electrical metal weaving layer, and ensure the integrity of the protective cover, this performance can be tested through a spark test. The test voltage is 3000V. The surface electrode of the spark machine is not less than 0.1s. In some occasions, such as long -term exposure, we need to consider UV prevention.

       Corrosion

       Wetness is easy to breed mold or corrosion areas, and the external corrosiveness of the tropical part is considered. If the electrical partner is used in places that are easily corrosive, such as petroleum and chemical industry, then the electromatoplasts must be made of fluoroplasty.

       Softness

       The tropical sheet of the electricity should also consider its softness. Generally, the diameter of the bending radius is 5 times that of its diameter. Because the performance of the outer care suit directly affects the safety of the tropical use of the electric partner, most of the tropical parts of the temperature and the tropical part of the temperature use the polyolefin outer sheath, which can not only further enhance its overall protection performance, but also cause users to have one more layer of safety guarantee.
