The cable is one or more insulated conductors, which are twisted together and dressed in impenetrable, impermeable shell. In some cases it may be provided with an additional layer, protects against all kinds of mechanical damage. Such products and the company offers "CABLE CENTER».
types of products
Among the most popular electrical sphere products are the following:
- Power. It consists of living, made of copper or aluminum, which have a round or sector-shaped, insulated and covered with a sealed envelope. Used for the purpose of distribution and transmission of electricity.
- telephone cable. It is fundamentally different from all other types of wires, as it consists of much more lived (they can be, how about a hundred, and thousands of). they are connected with each other chetverochnoy, and double twist. Produce it in several embodiments, the shell, but usually it is made of metal or plastic. In recent years become popular products, shell of which is made of metal-.
- Control. It used in the process of connection of electrical devices and appliances, Terminal blocks, which are directly in the signaling network, Control and automation. These products consist of copper or aluminum conductors and protected by a special sheath.
Not surprising, that is the first place in demand not TSV cable, and power. It is presented in a wide range due to the fact, which is made of different material combinations. Types of insulation of these cables may be several. They are directly dependent on the design features, voltage values of the light conditions and the further operation. Existing same kinds of telephone cables are directly dependent on, for which they are intended.
Materials for insulation, made of rubber, are not only artificial, but also of natural origin. The undeniable advantage of such protection is considered to be varieties of increased flexibility, due to which the assembly takes place completely in all conditions. Although it is, such insulation later time becomes less reliable, due to the fact, that its operating properties deteriorate.
Additional Persistent species isolated isolation polyethylene of high and low density, since he is not afraid of sudden changes in temperature and rainfall. Communication cables telephone often have a porous, paper or air porous insulation.
The most common among all the cables are considered the controlling, Power and telephone. However, currently gaining popularity and fiber, Twisted Pair, and many others. With the advancement of technology there is a need to develop and Wire and cable industry.
