What is the size of MINK conductor?

6/3.66 mm Al + 1/3.66 mm steel — 63.13 mm² of aluminium plus 10.52 mm² of steel, 73.65 mm² total, with an overall diameter of 10.98 mm.

What is the weight of MINK conductor per km?

256 kg per km, so a 1 km drum weighs about 0.26 tonnes.

What is the resistance of MINK conductor?

0.4565 Ω/km DC at 20 °C. At 75 °C the AC resistance rises to roughly 0.5856 Ω/km once skin effect is included.

Construction of MINK

MINK is built as 6/3.66 mm Al + 1/3.66 mm steel. Aluminium strands over a galvanised steel core. The steel core takes most of the mechanical tension so the aluminium can be sized purely for current, which is what lets ACSR span long distances between towers. The total metallic area of 73.65 mm² and overall diameter of 10.98 mm set both the resistance and the wind/ice loading the structures must carry.

Where MINK is used

11 kV and 22 kV feeders with moderate loading. At 234 A on the standard basis, a three-phase circuit of MINK carries roughly 4 MVA at 11 kV, 13 MVA at 33 kV and 53 MVA at 132 kV — useful as a first sanity check before detailed load flow.

Conditions behind the current rating

Ambient 40 °C, maximum conductor temperature 75 °C, cross-wind 0.61 m/s, solar radiation 1000 W/m², emissivity 0.9, absorptivity 0.8, outdoor overhead installation (IEEE 738 / IS 398 practice).

Wind is the single biggest variable. Removing it drops the rating of MINK from 226 A to 117 A in the cases above.
Raising the permitted conductor temperature increases the rating, but sag and long-term annealing of the aluminium set the practical ceiling — 75 °C continuous is the usual limit.
A weathered, dark conductor absorbs more sunlight but also radiates heat better; the standard 0.8 absorptivity / 0.9 emissivity pair is the conservative combination.
Terminations, jumpers and clamps often limit a line before the conductor does. Check the whole current path, not only the span.
