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.
Good insulation performance: Due to an additional insulation layer, insulated overhead conductors have better insulation performance than bare conductors, which can reduce the distance between phases, lower the insulation requirements for line supports, and increase the number of circuits on the same pole.
Strong corrosion resistance: The outer insulation layer reduces the degree of oxidation corrosion on the conductor, providing strong corrosion resistance and extending the service life of the line.
Protection against external damage: It can reduce the impact of external factors such as trees, flying metal films, and dust, thereby lowering the incidence of phase-to-phase short circuits and grounding accidents.
Meets mechanical strength standards: Although some insulated conductors may not contain a steel core, their tough material allows the entire conductor to meet the mechanical strength requirements of stress design.

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.

Performance Characteristics of Steel Core Aluminum Stranded Wire
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.
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.
