Extension bar
 Busbar is made of copper. Alternatively, for aluminium busbar, a bimetal sheet of
appropriate thickness and capable of carrying full load current shall be provided pre-fixed on the
extension busbar for the connection to the LV copper cables.
Two earthing terminals shall to be provided, located diagonally opposite on either side of the
undercarriage. Both terminals shall be made for stainless steel and have M12 threads and
indicated with earth symbols labels.
The minimum external air clearances for altitude 1000 meter and below shall be in accordance
with the following:
Nominal System         415 V
Voltage                      77
Minimum Clearance   58
Phase-to-Phase        11 kV
Minimum Clearance   254
Live Metal-to-Earth    203
With the exception of HV, LV and neutral terminals, all exposed conductors shall be properly
insulated with non tracking hydrophobic insulation if the clearance between the conductors
could not be achieved as specified above.
