Release Date:
2025-07-11
Lightweight and High Strength: Steel core aluminum stranded wire is lightweight, about half the weight of traditional concentric conductors, making it easy to install and transport. The addition of the steel core significantly enhances the tensile strength of the conductor, enabling it to withstand greater mechanical stress, suitable for long-distance, large-span overhead lines.
Lightweight and High Strength:
Steel core aluminum stranded wire is lightweight, about half the weight of traditional concentric conductors, making it easy to install and transport.
The addition of the steel core significantly enhances the tensile strength of the conductor, allowing it to withstand greater mechanical stress, suitable for long-distance, large-span overhead lines.
Excellent Conductivity:
Aluminum stranded wire has good conductivity, with relatively low resistance, which can reduce power loss during transmission.
The high density of aluminum stranded wire further improves the overall electrical conductivity, ensuring stable and reliable current transmission.
Strong Corrosion Resistance:
Aluminum wire has anti-oxidation properties in the air, forming a dense aluminum oxide protective layer on the surface, effectively preventing further oxidation and corrosion.
The steel core is usually treated for rust prevention (such as galvanization) to prevent electrochemical corrosion and extend service life.
Good Thermal Stability:
The steel core has a high recrystallization temperature, maintaining normal mechanical strength even at high temperatures, ensuring safe operation of the conductor in high-temperature environments.
Excellent Wind and Vibration Resistance:
Steel core aluminum stranded wire has high tensile strength and elastic modulus, enabling it to remain stable under wind forces and reduce wind-induced damage to the conductor.

Low-voltage power cable laying methods and precautions
Direct Burial: Suitable for scenarios with a small number of cables and long routes. The trench depth must be ≥0.7m (≥1m in farmland), with soft soil or fine sand laid at the bottom, and protective boards covered above the cables. Cable Trench Laying: Suitable for scenarios with many cables and requiring easy maintenance. Keep the trench dry and install drainage facilities.
Main Features of Insulated Overhead Conductors
Good insulation performance: Due to the additional insulation layer, insulated overhead conductors have better insulation performance than bare conductors, which can reduce the phase-to-phase distance of the line, lower the insulation requirements for line supports, and increase the number of circuits on the same pole.

Understanding Overhead Insulated Conductors: Benefits and Applications
Overhead insulated conductors (OIC) are increasingly becoming a vital component in modern electrical distribution systems. Unlike traditional bare conductors, OICs are equipped with a layer of insulation that provides significant advantages in terms of safety, reliability, and operational efficiency.
