FLAT
& SHAPED WIRE SPECIFICATION
5 - 25mm (width) x 1 - 8 (thick) E.C. Grade Copper flat wire
1.
Feed Stock
Oxygen Free High Conductivity Copper Rods manufactured at Copper wire
plant using "Dip Forming" technology. Chemical composition is in accordance
with LME Grade A specifications. A low Silver copper alloy ( 0.03
and 0.1 % Ag) produced in Dip forming plant is also used as a material
for colector and troley wire.
2. Manufacturing
Process
Rectangular copper strips are manufactured according to DIN46433
using cold rolling , drawing and heating in 3 various tempers -
annealed, semi hard, or hard, upon the customers request and further
isolation

7. Shaped
wire
Various
types of shaped profiled wire such collector or
trolley wires are also produced . They have many applications
in production of DC/AC motors and trolleys for railways
. Almost every shape can be produced under the desired tolerances.
The raw material can be either pure copper or copper with silver
( 0,03 or 0,1 %Ag)
8.
Surface Quality
The
strips shall be smooth and free from grease, cracks and other imperfections.
9.
Packing
