Electrical resistance

  1. “If the d.c. resistance of the coated wire is measured at a room temperature (T 0C) other than 200C, it shall be corrected to 200C using the temperature coefficient {1 + 0.005(T -20) 0C}.”

  1. “Based on an equivalent resistivity of 13.8 x 10-8 ohm-m. For intermediate sizes, values of maximum resistance should be calculated using this value.”

Coil Dimensions

Inner coil diameter     –  480 – 485mm

Outer coil diameter    –  700 – 800mm

Coil height                 –  500 – 700mm

Coil packing

The coil has starting-end wire sample of maximum 1.5 meters length.

Each coil is provided with labels (Tag and Ticket) for identification purposes with manufacturer’s name, date of manufacture, coil batch number, size of wire, weight, and other markings as may be agreed upon with customer.

Four (4) steel straps (minimum 19mm width) for each coil.

The coil is wrapped with 120 microns plastic sheet.
