AL-59 CONDUCTORS


AL-59 Alloy Conductors are used in power transmission and distribution lines for a wide voltage range-low voltage to Ultra high Voltage.

COMPLIANCE WITH STANDARDS

AL-59 Alloy Conductor complies with the standard SS4240814 and AL-59 alloy wires complies with standard SS4240813 that specifies the limits for conductivity, strength and creep irrespective of the chemical composition which is not discussed in this standard. Other properties are similar to conventional AAAC conductors.

Size of the conductor
AL-59 conductors range form AL-59 31 sq-mm (7/2.38 mm)toAL-59 910 sq-mm (61/4.36 mm)

Strength of the wire

  • For diameter less than 3.5 mm: 250 MPA
  • For diameter less than 4 mm: 240 MPA
  • For diameter less than 4.5 mm: 230 MPA
Resistivity of the wire
  • Individual resistivity: 29.30 nOm
  • Average resistivity: 29.08 nOm
Creep of the conductor
Maximum conductor creep at 23°C at 40% of rated tensile strength and 1500 hours are as follows
  • 7 strands: 350 mm/Km
  • 19 and 37 strands: 400 mm/Km
  • 61 strands: 450 mm/Km
