Spot supply of steel core aluminum stranded wire JL/G1A-70/10 for power special steel core aluminum stranded wire

Description :

　　For high-voltage transmission lines, due to the limited path of the line and the fact that it is impossible to install multiple lines on one path, people have come up with the idea of using a single path, a set of iron towers, and hanging multiple wires. The function of steel core aluminum stranded wire is equivalent to installing multiple lines on one line. For example, for 500KV transmission lines, China mostly adopts the method of hanging four wires, and the method of using steel cored aluminum stranded wire is called same tower parallel installation. The function of steel cored aluminum stranded wire is why some rods are used for LJ; The main reason for using LGJ as well.

　　During the construction of overhead transmission lines, the commonly used connection methods for the connection between steel core aluminum stranded wire conductors and the tension connection between steel core aluminum stranded wire conductors and fittings are mainly hydraulic crimping technology. The compression molds used for different specifications and models of steel core aluminum stranded wire are often different. Generally speaking, the outer diameter of the steel core aluminum stranded wire tube is equal to the diameter of the mold. When purchasing construction tools and equipment, the steel core aluminum stranded wire should be based on the actual hardware received to avoid delaying construction. There are mainly various products such as steel core aluminum stranded wire, aluminum stranded wire, etc. The function of steel core aluminum stranded wire is available for everyone to choose from.

　　On the contrary, the budget cost for power cables is too high. The Xi'an steel core aluminum stranded wire used for high-voltage transmission is due to its low aluminum density; In the case of equal volume, aluminum has a smaller mass and better conductivity than iron and copper, while current has a "skin effect" during transmission. The function of steel cored aluminum stranded wire is to flow along the surface of the wire. The middle of Xi'an steel core aluminum stranded wire is steel wire, and the outer edge is aluminum wire; The reason for using steel core is that the strength of aluminum is not good, and the steel core aluminum stranded wire is soft and easy to break. Using a steel core can increase the strength of the wire without affecting its conductivity.

　　An overhead cable is a conductor consisting of single or multiple layers of aluminum stranded wires with an extruded insulation layer on top. The function of steel core aluminum stranded wire is relative to that of cable. Xi'an steel core aluminum stranded wire is a line that transmits electrical energy by erecting wires at a certain height through towers. The use of steel core aluminum stranded wire for ground insulation in high-voltage transmission and distribution network overhead lines generally relies on air. Previous distribution lines (except for 380V below 10kV) generally used bare wires. However, due to the complex distribution environment in urban areas, short-circuit grounding and lightning strikes often occur, resulting in reduced power supply reliability. Therefore, currently, insulated wires (i.e. the outer layer of the wire is wrapped with insulation) are generally used for overhead lines below 10kV, which is called insulated overhead lines.
