The low-voltage self-supporting cable is a type of aerial classification cable in which phase-coated aluminum conductors (along with conductor lighting conductors) are wound around a strand of aluminum alloy conductor (which also acts as a zero) with a strand of steel wire. Formed as retainers, both of which are coated, wrapped. The whole set is called an ABC cable. Low pressure self-supporting cable in this standard with insulated support wire can be used in two ways:

Steel-reinforced aluminum conductors are a combination of 1350-H19 aluminum wires woven in one or more layers around a steel core in the center with a round cross section. The steel core can consist of one or more strands (7,19,37 strands). ACSR conductors comply with ASTM standard requirements
Electricity distribution systems use ground cables and overhead lines to provide electricity to consumers. Air distribution networks have advantages over land networks such as the following.
All-aluminum conductors include 1350 aluminum wires that are woven as a layer around a central wire with a round cross section. Each layer has 6 more strings than its previous layer. The high flexibility of these conductors has increased the number of layers at a certain cross section.
Aluminum alloy conductors are conductors whose entire strands of wires are made of aluminum alloys. Initially, 5005 aluminum was used to make these wires, the strength of which is only due to hard work, but aluminum alloy 6101 and 6201, which is also capable of heat treatment, in the construction of these conductors, due to its high strength at high working temperatures of lines. The transition has expanded dramatically. The use of aluminum alloy conductors first began in the United States in 1921, and then in the 50s and 60s of these conductors for transmission and distribution lines in European countries (Germany, France, etc.) and also Japan was used extensively.
Aluminum-coated aluminum conductors (ACSR / AW) are used in distribution and transmission lines and in areas where corrosion resistance and high temperatures are required. These conductors are often used in areas where there is air pollution and along the coast or industrial areas.
