BS 215 Standard ACSR Rabbit Aluminum Conductor Steel Reinforced Cable

The ACSR Rabbit conductor is a specific type of aluminum Conductor Steel Reinforced (ACSR) cable commonly used in overhead power transmission and distribution. It is designed for applications where both electrical conductivity and mechanical strength are crucial.

Components and Structure

1. Aluminum Strands:

   • Material: Hard-drawn 1350-H19 aluminum.
   • Configuration: Typically composed of six aluminum strands helically wrapped around a single steel core strand.

2. Steel Core:

   • Material: Usually galvanized steel for corrosion resistance.
   • Purpose: Provides high tensile strength to support long spans and withstand mechanical stresses.

Specifications

• Standard Size: ACSR Rabbit conductors are generally specified by their nominal aluminum cross-sectional area and overall diameter.
• Conductor Size: Commonly, the Rabbit conductor has an aluminum area of around 50.5 square millimeters.
• Stranding Configuration: Typically 6 aluminum strands around 1 steel strand.
• Overall Diameter: Approximately 9.02 mm.

Electrical and Mechanical Properties

• Current-Carrying Capacity: ACSR Rabbit conductors can carry significant electrical loads, making them suitable for medium to high voltage applications.
• Breaking Strength: The steel core provides high tensile strength, often in the range of 13.32 kN (kiloNewtons), allowing the conductor to span long distances between support structures.
• Resistance: Electrical resistance is relatively low due to the aluminum strands, ensuring efficient power transmission with minimal losses.
