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 life, electricity is used in all industries and fields. If there is no electricity, the development of society will stagnate, so we can see the importance of electricity. Of course, wires and cables are closely related to electricity. With the continuous development of scientific and technological networks, the demand for wires and cables is also increasing, and the specifications of cable models will continue to increase, so it is really not an easy task to truly master this knowledge. This requires us to learn a little bit at ordinary times and accumulate slowly.
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, they have the characteristics of higher technical content, stricter use conditions, smaller batches and higher added value. Special cables often use 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 conditions of use, 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 energy development, steel, aerospace, oil exploration and metal smelting and other fields. Low-noise cables are mainly used in fields such as medicine, industry, and national defense that require small signal measurement, and bass can be perceived. In addition, there are functional wires and cables and new green cables.
The development direction of special cables is diversified. In the military industry, there is a particularly high demand for cables that are lightweight and resistant to high temperatures. The demand in construction is mainly for 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 fire and safety accidents. At present, most of the radiation cross-linked or silane cross-linked wires and cables are light-weight, small in size and resistant to high temperature. Among many types of special cables, several high-temperature cables have the highest market demand, and are widely used in various short-distance transmission of large current occasions, and the supply is in short supply. For example, BTTZ mineral magnesium oxide insulated fireproof cable has the characteristics of high temperature resistance, fireproof, explosion-proof, non-combustion, large current carrying capacity, small outer diameter, high mechanical strength and long service life.
