 NSPB
is used as an interconnection between two load
centres in LT systems.However even for higher
voltages NSPB are used.
NSPB consists of enclosure in rectangular form
with conductors in the form of flats/channels
of Aluminium / copper material. These conductors
are usually supported on FRP supports. Unlike
SPB, NSPB has no phase barrier.
Segregated
Phase Busducts upto 5.0kA, 12kV/24kV. BIL 75kV
(peak) respectively are also available for use
as an alternative Busduct to Isolated Phase
Busduct. The enclosure can be MS upto 2500A
and above 2500A it will be alluminium enclosure.
Conductor can be Aluminium or copper, Supported
on Porcelain or Cast Resin Insulators.
