ACSR Conductor

BS215-2 Specification for Aluminum Conductors Steel Reinforced for Overhead Transmisison. This specification specifies minimum technical requirements for the design, manufacturing, testing, inspection, performance, general requirements and supply of Aluminum Conductors Steel Reinforced (ACSR) bare conductors for use in medium voltage (MV) WEZA POWER distribution network.

Number of strands, dimensions and area of the ACSR conductors

Low Voltage Aerial Bundled Cables– Type I “Self-Supporting”

➢ LV-ABC 4x50

➢ LV-ABC 2x50 mm²

➢ LV-ABC 4x16 mm²

➢ LV-ABC 2x10 mm²

The rated voltage of the cable is 0.6 / 1.0 kV, whereas 600 volts is the rated power frequency voltage between conductor and earth for which the cable is designed and 1,000 volts is the rated power frequency voltage between conductors, for which the cable is designed. This cable is hereinafter referred to as aerial bundled cable or ABC.

ABC cables shall conform to the latest editions of the IEC standards applicable to their construction, including but not limited to those listed below, and to their normative references:
