The difference between special cables and ordinary cables

- Jul 16, 2020-  


In today's life, electricity occupies every aspect of people's lives. If there is no electricity and people live in a dark environment, I believe that not many people can bear it. In addition to people's daily lives, electricity is used in all industries and fields. Without electricity, social development will stagnate. Therefore, we can see the importance of electricity. Of course, wires and cables are closely related to electricity. With the continuous development of science and technology networks, the demand for wires and cables is also increasing, and cable models and specifications will continue to be added. Therefore, it is really not an easy task to truly master this knowledge. This requires us to learn a little bit and slowly accumulate. Let me introduce the difference between special cables and ordinary cables!


Special cables are a series of products with unique properties and special structures. Compared with ordinary wires and cables with a large quantity and a wide range, special cables have the characteristics of higher technical content, stricter use conditions, smaller batches, and higher added value. Special cables often adopt new structures, new materials, new design calculation methods and new production processes.


Special wires and cables are different from ordinary cables. Special cables are generally used in special occasions or under specific use conditions, and their functions are also special, such as high temperature resistance, strong acid and alkali resistance, and termite resistance. Among them, high temperature resistant wires and cables are mainly used in the fields of energy development, steel, aerospace, petroleum exploration and metal smelting. Low-noise cables are mainly used in fields such as medicine, industry, and national defense that require small signal measurement to detect bass. In addition, there are functional wires and cables and new green cables.


The development direction of special cables is diversified. The demand for light-weight and high-temperature-resistant cables is particularly large in the military industry. The demand for construction is mainly double-layer flame-retardant and high-temperature resistant wires and cables and low-smoke, halogen-free and environmentally friendly wires and cables, mainly to prevent hidden dangers of fire and safety accidents. At present, most of the light-weight, small-sized, high-temperature-resistant radiation cross-linked or silane cross-linked wires and cables are used. Among the many types of special cables, several high-temperature cables have the highest market demand. They are widely used in various short-distance transmission large current occasions, and the supply exceeds demand. For example, BTTZ mineral magnesium oxide insulated fireproof cable has the characteristics of high temperature resistance, fireproof, explosion-proof, non-combustible, large current carrying capacity, small outer diameter, high mechanical strength and long service life.


From the above, we can see that with the development of society and the continuous growth and development of application fields, different industries are not satisfied with the usual common wire and cable, and the special wire and cable emerges, so many people do not I know how to distinguish these special wires and cables, and I don't know what special wires and cables are. Now, through the summary of the editor, I believe that many people have a certain understanding of special wires and cables.
