ALUMINUM ALLOY CONDUCTOR STEEL REINFORGED (AACSR)

LS Cable & System overhead wire is composed of ACSR and overhead ground wire. They are normally installed on steel towers, and recently the usage of high-capacity conductors for high-capacity transmission among power cables is increasing

Construction

AACSR is a concentrically stranded conductor composed of one or more layers of aluminum alloy wire stranded with a high-strength coated steel core. The core may be single wire or stranded depending on the size.

Steel core wires are protected from corrosion by galvanization. Additional corrosion protection for conductor is available through the application of grease.

The proportions of aluminum alloy and steel can be varied to obtain the relation between current carrying capacity and mechanical strength best suited to each application.

Standard

Aluminum Alloy conductor Steel Reinforced can be supplied to meet various International standards and National standard as follows:

IEC 1089 - International standard

ASTM B 711 - American standard

DIN 48206 - German standard

NFC 34-125 - French standards

AS 3607 Standard

However, LS VINA Cable & System can also supply a range of alternative designs to meet customer-specified Requirements.

Application

Aluminum Conductors, Steel-Reinforced (ACSR) can be used in Medium, High and Extra-High voltage transmission lines; also used for primary and secondary distribution lines. The combination of aluminum and steel in the conductor design offers both efficient conductivity and high tensile strength making ACSR the most economical solution for overhead power transmission and distribution projects.

NOTE Guideline values of current carrying capacity are valid up to a frequency of 60 Hz, assuming a wind velocity of 0,6 m/s,the ambient temperature of 35 °C and a conductor temperature of 70 °C.

For special applications, when there is no air turbulence, the values should be reduced by 30 %.
