Parameters

The calculated values on this data sheet are based on the following parameters:
Ambient temperature ºC 35
Busbar temperature ºC 65
Temperature rise ºC 30
Supply Frequency Hz 60
Emissivity 0,4
n= number of bars in parallel Current ratings assume still but unconfined air, with busbar mounted on edge. Current ratings are based on “Temperature Rise of Busbar”, H.B.Dwight; Gen. Elec. Rev., vol 43. For multiple bar arrangements, the space between bars is equal to busbar thickness. AC ratings are based on spacings at which the proximity effect is negligible. These approximate calculated values should not be regarded as a subsitute for experimental testing

Recommendations for drilling, punching and cutting

CUTTING Copper-Clad Aluminium (CCA) busbar can be cut using methods that apply to aluminium. Grinding of cut saw to a trapezoidal shape gives good results and deburring is not necessary. Cutting speed: 50-90 m/sec Lubricant and coolant white spirit.
DRILLING Recommended drill characteristics: Drill cutting angle Cutting speed: 50m/min Cutting tool angle:135º-140 Helix angle: 45º Lubricant and coolant white spirit.
PUNCHING The punching tool should be designed in the same way as for use with flat copper bars. It is important that the die should give adequate support as near as possible to the shearing edge.
BENDING N.B. Above factors are for bending normal to the plane. For edge bending the forming tool radius should be multiples of the width w.
