The secondary winding is also manufactured from a
one-piece aluminium foil conductor, the height of which
equals the whole column. Special winding transformers
ensure a compact, cylindrical coil, which resists both
the axial and radial stresses generated by short
circuits. |
|
Moreover, since the turns are completely free from air
pockets, the exceptional compactness of the windings
also guarantees very uniform heat dissipation. |
|
Welding to the busbars is carried out by fusion and
without weld material. Conductors are butt-welded to
prevent the formation of raised weld joints, which might
cause damage to the insulation between outlet terminal
and turn. |
|
A vacuum resin-impregnation process ensures total
protection of the product against humidity, salinity and
pollution. |
| The coils may be exposed to even the
most demanding environments, in full compliance with
class E2. |
