At present, it is impossible to imagine construction and industrial production without the use of various types of cables. In this regard, there is a fairly large number of cable products that differ in their field of application, structure and technical characteristics. Therefore, the main types of cables and their features should be considered in more detail..
As the first type of cables, it is necessary to consider signal-blocking cables. This category includes products with conductive conductors made of copper and placed in polyethylene insulation and in a plastic sheath. The main area of use of such cables is electrical installations of railway signaling, centralization and blocking at a nominal alternating voltage of 380 V or constant voltage of 700 V.
Power cables are used for the transmission and distribution of electrical energy in stationary electrical installations. This type of VVG cable, the price of which is quite low, is very common. For its manufacture, aluminum or copper wire is used. Oil-impregnated paper tape is used as insulation material. The operating voltage range for this type of cable is from 600 to 500 kV.
Control cables have copper or aluminum conductors with plastic insulation. They are mainly used for switching electrical appliances, apparatus and devices for the operation of which a rated voltage of up to 660 V and a frequency of up to 100 Hz is used..
Communication cables have several subspecies. These include telephone and radio frequency cables. Telephone cables include cables that are used when laying fixed subscriber telephone networks..
RF cables are intended for switching various radio devices and RF installations. They also come in several types: RF coaxial cables and RF balanced cables, which can be two-core or two coaxial pairs..
The latter type includes control cables, which include products with conductive copper conductors with plastic or rubber insulation. Their main area of application is control, information and monitoring circuits of various electrical installations with a rated operating voltage of up to 1000 V.
