What are the different types of conductors and insulators for power lines?

2025-08-09

The choice of conductors and insulators depends on the specific requirements of the transmission project, such as voltage level, span length, and environmental conditions.

  • Conductors:

    • All-Aluminum Conductor (AAC): Lightweight, good conductivity, but lower tensile strength, making it ideal for short spans and distribution lines.

    • All-Aluminum Alloy Conductor (AAAC): Offers higher tensile strength and better corrosion resistance than AAC, suitable for coastal areas and medium spans.

    • Aluminum Conductor Steel Reinforced (ACSR): The most common type for high-voltage transmission, featuring a steel core for superior strength and a durable aluminum outer layer.

  • Insulators:

    • Pin Insulators: Used for lower voltages, mounted on cross-arms.

    • Suspension Insulators: A series of discs connected together, used to hang conductors on high-voltage lines.

    • Strain Insulators: Designed to handle mechanical tension at corners and dead ends of the line.

Our company manufactures and exports a full range of conductors and insulators, ensuring you have the right solution for any project, from low-voltage distribution to extra-high voltage transmission.
