H01N2-D BS EN 50525-2-81 Welding Cable 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. Cable Standards: Made in accordance with the following: BS EN 50525-2-81 (previously BS 638 Part 4, CENELEC HD22.6, VDE0282-6), BS EN 60332-1-2 Construction: Conductor : Generally to Class 6 flexible copper conductor according to BS EN 60228 (previously BS 6360) Separator : PET (Polyester Tape) Sheath : Rubber compound, Type EM5 according to BS EN 50363 Characteristics: Voltage Rating : 100V Temperature Rating : -40C to +85C (Fixed) -20C to +85C (Flexed) Min. Bending Radius : 6 overall diameter (Flexed) Sheath Colour : Black & Red Electrical Characteristics: 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 = I 100/F 100 Where: I : is the maximum permissible loading current for the required duty cycle. I : is the maximum permissible loading current for a duty cycle of 100%. 100 F : is the required duty cycle calculated as a percentage of the 5 minute operation period. www.element14.com www.farnell.com www.newark.com www.cpc.co.uk Page <1> 15/05/15 V1.1H01N2-D BS EN 50525-2-81 Welding Cable 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% Current Carrying Capacity: Current Rating for Single Cycle Operation over a Maximum Period of 5 Minutes Nominal Cross Amps Sectional Area 2 mm 100% 85% 60% 35% 10 100 103 108 122 16 135 145 175 230 25 180 195 230 300 35 225 245 290 375 Ambient Air Temperature : +25C Max.
