Application

AAAC is mainly used as bare overhead transmission cable and as primary and secondary distribution cable. It is also suitable for laying across basins, rivers and valleys where special geographical teatures exist.

Standards:

Basic design to BS 3242 / BS EN 50182 / IEC 61089 / ASTM B 399/B 399M / DIN 48201-6 / AS 1531 standards.

Electrical Properties

Density@20oC: 2.70 kg/dm
Temperature Coefficient@20°C: 0.00360 (°C)
Resistivity@20°C: 0.0326 Ohms mm^2/m
Linear Expansivity: 23 x10-6(°C)

Service Conditions

Ambient Temperature: -5°C - 50°C
Wind Pressure: 80 – 130kg/m^2
Seismic Acceleration: 0.12 - 0.05g
Isokeraunic Level: 10 – 18
Relative Humidity: 5 – 100%

construction

AAAC cable bvconsists of aluminum alloy wires. The aluminum alloy wires are concentrically stranded.
This section deals with heat-treatable magnesium silicon type aluminium alloys to the applicable International Standard, the electrical and mechanical properties of which all fall within the values suggested by relevant standard.
Conductors to all other recognized specifications can also be supplied. The alloys referred to have higher strength but lower conductivity than pure aluminium.
Being lighter, alloy conductors can sometimes be used to advantage in place of the more conventional ACSR; Having lower breaking loads than the later, their use becomes particularly favourable when ice and wind loadings are low.
