Some knowledge points of steel core aluminum stranded wire
At present, the steel core aluminum stranded wire is the main application of the main line of China's power system. For a long time in the future, ACSR will still be the main product used in China's power grid, which is mainly determined by the characteristics of ACSR and the design characteristics of China's power grid.

What is an overhead line and what is a cable?
Overhead lines are wires, usually bare conductors, erected in the air through towers and concrete towers. A cable consists of one or more mutually insulated conductors and an outer insulating protective layer, which is used to transmit power or information from one place to another.

Difference between overhead line and cable
Overhead lines are wires, usually bare wires, that are erected in the air through towers and concrete towers. Although the overhead line is cheap, it occupies a large channel area and is the main line style at present.

Requirements and construction specifications for overhead lines
Overhead lines shall be made extensively of steel-reinforced aluminum stranded wire or aluminum stranded wire. The aluminum stranded section of the high-voltage overhead line must be larger than 50 mm², and the core aluminum stranded section must be larger than 35 mm². The blank line section is not a 16 mm².

Overhead line sag observation and inspection operation
The role of arc: in the circuit design, the vertical value of the arc can be strictly calculated to ensure a sufficient safe distance to the ground and the cross, and to ensure the circuit stress within the allowable range. During construction, the observation arc vertical can be calculated according to the designed arc vertical value, and strict observation and inspection can be carried out to ensure the construction quality and the safe operation of the circuit.

How to Choose High Voltage Cable
We usually say that the high-voltage cable is actually one of the power cables. The components of the high-voltage cable from the inside to the outside are conductors, insulation, internal shielding, filling materials (sheath), and external insulation. Of course, sheathed high-voltage cables are mainly used for underground burial, only to transmit power cables between 1kv-1000kv, and are mostly used for power transmission and distribution. The product is suitable for fixed power transmission and distribution lines with AC rated voltage below 35KV, which can resist the pressure of high strength on the ground and prevent damage caused by other external forces. The long-term use temperature of the cable conductor is 90 degrees, and the cable conductor is short-circuited (below 5S for a long time)

Basic principles and requirements for selection of high-voltage cables
About high-voltage cables, mainly look at the wires on the poles and the cables in the underground pipe network. Because the selection of high-voltage cable considerations are quite complex, and there are quite a lot of types, then, let's understand the basic principles and requirements of high-voltage cable selection together!
