Practicability of high temperature resistant cable protective sleeve

Resistance to high temperature cable protection sleeve is mainly used in electric power, chemical and other industries in the high temperature region; fast changing joint of metallurgical enterprises heating cable, fluid lines, feed, rolling roller, rolling mill cable, tubing; sawing surrounding cable, tubing and fittings; steel chartered cable coating and so on field.The performance of high temperature resistant cable protection sleeve is as follows:
1 、safety and environmental protection, to protect the health of workers
Non alkali glass fiber itself is pulling an exceptionally strong, will not wrinkle broken, sulfur resistance, low smoke, non halogen, non-toxic, pure oxygen combustion, good insulation properties, by organic silica gel after curing, more strong the safety and environmental protection performance, effective protection of workers health, reduce the incidence of occupational disease. Unlike asbestos products, such as great harm to human body and environment.
2、 high temperature resistant performance
The surface of the high temperature resistant cable protective sleeve is composed of an organic group and an inorganic structure, and the special composition and the molecular structure make the organic matter and the function of the inorganic matter in one body. Compared with other polymer materials, the most prominent is the high temperature resistance. Silicon – oxygen (SiO) key chain structure and C-C bond bond to 82.6 thousand cards / mole, SiO bond bond to 121 thousand card in the silicone / mole, so its high thermal stability, high temperature (or radiation) molecular chemical bond not broken, do not break down. Silicone is not only resistant to high temperature and low temperature resistance, can be used in a wide temperature range. Both the chemical properties and physical mechanical properties, with the change of temperature is very small.
3 、splash, multiple protection
In the smelting industry, electric heating furnace in the medium temperature is extremely high, easy to form high temperature spray (welding industry), cooling and solidifying in the pipeline, or cable slag formed will make the pipe or cable outer hardening of the rubber, and ultimately to brittle fracture. Further damage not the protection of equipment and cable, through multi-channel silica gel coated with high temperature resistant cable protective casing, can realize multiple safety protection, highest temperature resistance can be up to 1300 degrees Celsius, can effectively prevent the splash of molten iron, molten copper, aluminum melting and high temperature melt, prevent around cable and equipment from being damaged.
4、 heat insulation, energy saving, radiation resistance
In the high temperature workshop, a lot of pipes, valves or equipment, its internal temperature is very high, if not coated with protective material, easy to cause personnel burns or heat loss, etc.. Resistant high temperature casing, with than other polymer materials, better thermal stability and resistance to irradiation and thermal insulation effect, prevent accidents, reduce the energy consumption, also can prevent the heat of the medium in the pipeline is passed directly to the surrounding environment and the workshop of temperature is too high, saving cooling costs.
5 、moisture, anti oil, anti climate aging, anti pollution, increase the number of equipment used
High temperature resistant cable protection sleeve is of very strong chemical stability, silicone to oil and water, acid and alkali substances did not react, 260 DEG C, can use for a long time and aging, natural environment, service life of up to several decades, to maximize the protection of these occasions in the pipeline, cable and equipment, greatly prolongs the service life.
6 、ozone resistance, voltage resistance, arc resistance, corona resistance
Because the surface is coated with organic silica gel, the backbone for – Si – O, unique key exists, so it is not easy to broken down by UV and ozone. High temperature tube has good electrical insulation properties, the dielectric loss, resistant to voltage, arc resistance, corona resistance, volume resistivity and surface resistivity etc. were in insulating materials is one of the top and their electrical properties by the influence of temperature and frequency is very small. Therefore, they are a kind of stable electrical insulating material, which is widely used in the electronic and electric industry.
7、 flame retardant, reduce the incidence of fire and the spread of speed
If the pipeline transportation of flammable or toxic medium, leakage occurs easily lead to fire or injury; cables are also often by local high temperature and combustion; high temperature resistant cable protection sleeve using extremely resistant to high temperature of glass fiber woven into, the surface of silica gel added with proper flame retardants and other special material, which has excellent flame retardancy. Even if the fire occurs, can prevent the spread of the fire, still can protect the integrity of the internal pipeline for a long time, to the data, information and other important information to provide sufficient time for the rescue.
