Aluminum power cable has an aluminum metal conductor. Aluminum wires are used to create lighting electric networks, connect industrial equipment and mechanisms. As a rule, cables with an aluminum conductor are used in electric networks with a constant voltage level of not more than 1000 V and an alternating voltage indicator of not more than 450 V. They are different types. Depending on this, the products are the following categories:
· Isolated self -supporting cable. Used for installation of electrolytees passing through the air;
· Control cable. Used to create a fixed connection to electrical devices and equipment;
· Power cable. It is used to deliver electricity from producing places to the places of use, as well as inside the electric networks;
· Cables that are used to connect machines, machines, equipment, as well as to create power wiring;
Types of power cables made of aluminum. They can differ in the degree of flexibility, type and structure of insulation, permissible layout conditions. The most common of them are:
· ABVG — cable with an insulating coating of PVC. Used to deliver electricity (voltage up to 1 kV); · ALBBShv — a cable that, in addition to isolation from the material from the material, is equipped with a shell of steel tapes (reservation). This allows for its laying in zones with a high danger of various damage to the mechanical type;
ASBL — a cable equipped with a paper type with a lead shell. Has additional external protection from PVC and steel tapes. It is used to create lines in soils with relatively low levels of activity (low, medium), as well as in various mines.
Can be used outdoors. Cable control armored armored control cables are used to create motionless accessions to electrical equipment and for assemblies of clamps to electric distributors with a constant voltage of not more than 1000 V and a variable voltage of not more than 660 V with a frequency of up to 100 Hz. They are laid in the ground, tunnels and channels, in places that are influenced by wandering currents, as well as in aggressive conditions. Cables such as AKVBBSHNG and KVBBSHNG are used for laying in premises and structures with increased fire safety requirements. The end of «NG» at the end of the abbreviation means «non -combustible».
The armored power cable is used to create power networks in difficult conditions. Thanks to the design, this cable can be used to install power routes in conditions of aggressive media. It has protection in the form of armor ribbons, which create a very dense metal protective shell that protects against mechanical damage. A large list of sections makes it possible to use the power cable armored for the installation of electric networks. However, it is most often used for cable tracks that are in an aggressive environment.
The purpose of this cable is the transmission of electricity, as well as the power of installations and nodes operating at a voltage of 660 V and 1000 V. In networks with constant voltage, as a rule, one -cereal cable is used, which is characterized by high strength, protection from mechanical damage and fire safety. It can be used in mines, tunnels, trenches and channels. The cable is sometimes operated and indoors. The main condition for its successful use is the lack of stretching and preventing the effects of stretching forces.
