An electrical overhead line is composed of several critical materials, each serving a unique function. The three primary categories of materials are:

1. Conductors: These are the wires that carry the electrical current. The most common type is Aluminum Conductor Steel Reinforced (ACSR), which combines the low weight and excellent conductivity of aluminum with the high tensile strength of a steel core. For projects requiring specific performance, other materials like All Aluminum Alloy Conductor (AAAC) are also widely used.

2. Insulators: These devices prevent the electrical current from flowing from the conductors to the supporting structures. They are typically made of high-dielectric-strength materials such as porcelain, glass, or polymer composites.

3. Line Hardware and Fittings: This is a broad category that includes all the components used to physically connect, support, and protect the conductors and insulators. Examples include clamps, vibration dampers, spacers, and various bolts and brackets.

As a leading manufacturer of OHTL wire cable conductor tension stringing equipment, we provide the specialized tools necessary to handle and install these diverse materials without causing damage or compromising their integrity.
