Inside Overhead Conductors

Prysmian manufactures a wide range of bare overhead products suitable for both transmission and distribution applications. Prysmian’s TransPowr® bare overhead products are produced and tested in accordance with the latest ASTM specifications. 

Prysmian offers bare overhead conductors in several types, including all-aluminum conductors (AAC), all-aluminum alloy conductors (AAAC), aluminum conductor steel-reinforced (ACSR), aluminum conductor steel-supported (ACSS), and T-2® twisted pair AAC and ACSR. 

AAC is made from 1350 H19 aluminum, making it lightweight and corrosion-resistant, and ideal for overhead line installations where high strength or temperature ratings are not essential. AAAC, on the other hand, is constructed from high-strength 6201 T81 aluminum alloy and is commonly used for overhead line installations near ocean coastlines, where corrosion can be an issue for steel in ACSR constructions. ACSR combines the lightweight, high-conductivity properties of 1350 H19 aluminum with the high tensile strength and durability of steel. This type of overhead conductor offers greater tension, reduced sag, and longer spans than AAC and AAAC conductors. Standard ACSR designs are typically made with regular-strength Class A galvanized steel (/GA2).

Weatherproof line wire consists of a single conductor covered with either Linear Low-Density Polyethylene (LLDPE) or Cross-linked Polyethylene (XLPE). The conductors can be either compressed or consist of concentric strands made from Aluminum Conductor Steel-Reinforced (ACSR), All Aluminum Conductor (AAC), or solid copper. This type of weatherproof line wire complies with ANSI/ICEA S-70-547.

Tree wire is a versatile solution designed for areas with overhead power lines that may come into contact with trees or debris. Its wide range of applications, along with a durable covering that protects against electrical faults caused by such contact, makes it an ideal choice for various scenarios. 

Tree wire consists of a single conductor, which can be made from Aluminum Alloy Conductor (AAC), All Aluminum Alloy Conductor (AAAC), or Aluminum Conductor Steel Reinforced (ACSR). The conductor is covered with one of the following options: a single layer of thermoset, track-resistant material; a two-layer thermoset covering with a track-resistant outer layer; or a three-layer thermoset covering that includes both a track-resistant outer layer and a thermoset semi-conductive conductor shield. These designs, when used as spacer cables with the appropriate accessories, further enhance the versatility of tree wire.

Aluminum tie wire is a soft, solid wire made from aluminum. It is frequently used in the construction of overhead transmission and distribution lines to securely fasten components, such as conductors, to pin insulators. In addition, this wire is also employed for above-ground grounding applications during line construction.
