Steel core aluminum stranded wire JL/G1A-400/35 is a kind of reinforced conductor widely used in power and transmission line industry. The following is a detailed description of the product:

Product overview

The ACSR is formed by stranding aluminum wire and steel wire. The inside is a steel "core", and the outside is a multi-strand aluminum wire wound around the steel core by stranding. The steel core mainly plays the role of increasing strength, while the aluminum stranded wire mainly plays the role of transmitting electric energy. JL/G1A-400/35 is a model in this series, where "JL" refers to aluminum stranded wire, "G1A" refers to ordinary strength steel wire, and "400/35" refers to the nominal cross-sectional area of aluminum wire and steel wire respectively (in mm²).

Product Features

1. **High strength**: Due to the internal steel core as a reinforcement, ACSR has high tensile strength, which is suitable for large span and high load transmission lines.

2. **Good conductivity**: The external multi-strand aluminum wire is used as a conductor, which has good conductivity and can effectively transmit electric energy.

3. * * Heat and cold resistance * *: ACSR can maintain stable performance in a wide temperature range, and can allow the working temperature to reach 90 ℃ for a long time and 180 ℃ for a short time.

4. **Corrosion resistance**: The surface of the aluminum wire is treated and has a certain corrosion resistance, which can be used for a long time in harsh environments.

5. **Easy to erect and maintain**: ACSR has simple structure, convenient erection and maintenance, and can effectively reduce the cost of the line.

Technical parameters

Scope of application

ACSR JL/G1A-400/35 is widely used in overhead transmission and distribution lines of various voltage levels, especially suitable for busbars for large current transmission such as substations and power plants, as well as projects such as capacity increase and transformation of urban networks. Its simple structure, easy erection and maintenance, low cost of lines, large transmission capacity, long distance, but also conducive to cross rivers, valleys and other special geographical conditions of the erection.

purchase suggestion

When purchasing ACSR JL/G1A-400/35, it is recommended to pay attention to the following points:

1. Choose regular manufacturers: to ensure reliable product quality and compliance with relevant standards and specifications.

2. Check the technical parameters: check the technical parameters of the product according to actual needs, such as nominal cross-sectional area, outer diameter, DC resistance, etc.

3. Consider transportation and installation: ACSR is usually long and heavy, and the convenience of transportation and installation needs to be considered.

4. Consult professional advice: if necessary, consult power engineers or relevant industry experts to obtain more professional purchase advice.
