|
1. CONDUCTOR : |
|
Each conductor shall consist
of a solid round wire of annealed high
conductivity copper, smoothly drawn,
nominally circular in section , uniform in
quality and resistance and
free
from defects.
The quality of copper shall confirm to
IEC-28 or IS-12444. |
| |
2. INSULATION : |
|
Each conductor shall be insulated
with solid polythene and 100% virgin material
as per ASTM D 883. The polythene shall
confirm to ASTM-1248 Type II or III, Class A,
Category 4 or 5 and meet the parameters. |
| |
3.
PAIRING : |
|
Two Insulated
conductors shall be twisted together with
uniform lay to form a pair. The length of
the lay of any pair is kept different from
that of adjacent pairs. The lay of various
pairs are chosen as to satisfy the
Electrical parameter requirement. |
