Covered Overhead Conductor — Tree Wire (Canada)

Tree wire is composed of a single conductor, which can be made from AAC (All Aluminum Conductor), AAAC (All Aluminum Alloy Conductor), or ACSR (Aluminum Conductors Steel Reinforced). It is covered with either a single layer of track-resistant material or a dual-layer covering featuring a track-resistant outer layer. Tree wire is manufactured according to the ICEA S-121-733 standard.

Conductors

• AAC: Features compressed stranding made from 1350-H19 aluminum, compliant with ASTM B231.
• AAAC: Comprises concentric stranding using a 6201-81 aluminum alloy, adhering to ASTM B399.
• ACSR: Contains concentric stranding of 1350-19 aluminum with a GA2 steel core, meeting ASTM B232 standards.

Coverings

Single Layer

• TR-HDPE: Black Track-Resistant High-Density Polyethylene.
• TR-HDXLPE: Black Track-Resistant Cross-Linked Polyethylene.

Dual Layer

• LLDPE/TR-HDPE: Linear Low-Density Polyethylene/Black Track-Resistant High-Density Polyethylene.
• XLPE/TR-HDXLPE: Cross-Linked Polyethylene / Black Track-Resistant Cross-Linked Polyethylene. 

Features and Benefits

The covering protects against faults caused by contact.

Applications

Designed for areas with overhead power lines that may come into contact with trees or other debris.

Options

Available in gray-colored HDXLPE or XLPE
