PET 100V Black Rubber Sheathed Welding Cable H01N2-E BS EN 50525-2-81
APPLICATION
These cables are used as a connection to welding robots in the
automotive industry, shipyards and for manually/automatically
operated lines and spot welding. The robust cable structure
makes them resistant to low and high temperatures, ozone and
radiation, oils, acids, fats and petrols.

Duty Cycle and Current Carrying Capacity:
The current carrying capacity of a welding cable depends on the length of the duty cycle. The duty cycle is the length of time during which a loaded current passes through the
cable over an operation period of 5 minutes, expressed as a percentage of that period. For example, if the current is flowing for the whole 5 minutes the duty cycle is 100%, and
if the current is flowing for 1 minute the duty cycle is 20%. As conductor temperature varies according to the time in use as well as current, ratings shown are given as a guide.
The permissible loading of the cable for duty cycles other than those shown in the table can be calculated using the following formula: I = I100 x √100/F
Where:
I : is the maximum permissible loading current for the required duty cycle.
I100 : is the maximum permissible loading current for a duty cycle of 100%.
F : is the required duty cycle calculated as a percentage of the 5 minute operation period.
Typical guidance values for different welding processes are as follows:
Fully automatic welding 100%
Semi-automatic welding 65 - 85%
Manual Welding 30 - 60%
Very infrequent or occasional welding 20%
