Welding Cables Double Insulated, Extra
Flexible, Orange and Black Jacket
|
FEATURES
:
- Based on CENELEC HD 22-6 31, VDE 0282
,IEC 245-6, IS 473,
BS 638-4.
- Outstanding toughness & durability.
- High resistance to cuts , tears &
abrasion.
- Resistance to oil , solvents and chemicals.
- Excellent ozone and weather resistant.
APPLICATIONS
:
Welding : Designed for the
secondary (high current) connection to automatic
or hand – held metal arc welding electrodes.
It is suitable for flexible use under rugged
conditions, on assembly lines and conveyor
systems, in machine tool and automatically
operated line and spot welding machines.
Power
: Earthing/return leads, power feeds
to electrolytic plating process, Busbar
connection, transformers, generators, aircraft
servicing equipments etc. |
 |
 |
| CONSTRUCTION
: |
- Conductor
: High conductivity, bare annealed
copper flexible conductor.
- Sheath
: Double sheathed with specially
developed thermoplastic Elastomer (TPR/TPE),
outer layer is orange coloured.
|
| CURRENT
RATING : The
maximum current ratings of flexible welding
cables for different duly cycles are based
on an ambient air temperature of 25 C and
a maximum conductor temperature of 90 C.
The percentage duly cycles for various processes
and applications are as follows: |
| 1 |
Automobile
Welding |
: |
up
to 100% |
| 2 |
Semi-automatic
welding |
: |
30% to 85% |
| 3 |
Manual Welding |
: |
0% to 60% |
| 4 |
Very
intermittent or
Occasional Welding |
: |
up
to 20% |
|
VOLTAGE
DROP :When total cable lengths
in excess of 15 mtrs., are involved , it
may be necessary to use cables of larger
cross section to ensure that the voltage
drop is not excessive and welding currents
are maintained at adequate levels. |
