Produktbeschreibung

ACSR/TW, Aluminium Conductors Steel Reinforced (ASTM B 779)

Construction

ACSR/TW, a non-homogenous conductor, is a trapezoidal shaped wire compact concentriclay- stranded conductor made from aluminum 1350-H19 (extra hard) wires and round, coated steel core wire(s). Several

combinations of aluminum and steel strands and layers are possible to design ACSR/TW conductors with equal area or equal diameter as compared to ACSR conductors for overhead lines. Commonly used sizes are included here. Class A zinc coating (ACSR/TW/GA2) is usually adequate for ordinary environments to protect the steel core wires from corrosion.

Specifications.

ACSR/TW conductors are manufactured in accordance with the ASTM specification B779. Other ASTM referenced specifications include B230, B498, B500, B 606, B802, B803, B957 and B958.

Features

The favorable strength/weight ratio, from the light weight and good conductivity of aluminum with the high tensile strength of steel, makes ACSR conductors a preferred choice for overhead power transmission and distribution projects. Steel strands provide mechanical reinforcement to handle higher line tensions, reduce sag, and longer span lengths. ACSR conductors are recognized for their dependable performance under adverse weather conditions. Use of ACSR/TW with the equal area design allows equal ampacity in a conductor with approximately 10% smaller diameter over a standard ACSR with same area. This smaller diameter of equal area ACSR/ TW conductors helps reduce the

effects of ice and wind loading on the conductor. Use of ACSR/TW with equal diameter design provides

a conductor in which the aluminum area is increased by approximately 20% – 25% over a standard ACSR with same diameter. This increase in the cross-sectional area of the conductor reduces its ac

resistance by about 15% – 20% and thus, increases its current carrying capacity by about 10%.
