3.3.1 Double body system (from 2500 A)
Busbar elements with high rated currents I
n
for 2500 A / 3200 A / 4000 A consist
of two parallel conductor bundles (Double body system, doubled conductor
system) In this case the conductors are installed together in two packs in one
housing.
-
Aluminium conductors: Double body system for rated current I
n
of 2500 A,
3200 A and 4000 A
-
Copper conductors: Double body system for rated current I
n
of 3200 A and
4000 A
The different conductors for the same phase are connected in parallel at each
connection joint (at least every 3 m for standard elements). Conductors for the
same phase thus undergo phase balancing at each connection joint to ensure
uniform current distribution. Special elements for phase compensation are not
necessary.
Installation efficiency, balanced load distribution
The solution with two parallel conductor packs in one housing has two major
advantages compared with other systems:
-
Quick, simple installation (phases need only be combined once)
-
Load distribution is balanced
