COMPARTMENTALISED DESIGN:
Multi - Tier Arrangement
Vertical Dropper Concept Permits
• 1 / 2 / 3 tier arrangement for ACBs.
•Up to 6 feeders(fuse switches) in a panel.
Flexibility in Compartment sizes
• Compartment sizes can be 300 to 900mm
• Facilitates 3 tier arrangement- Results in cost
effectiveness.
Auxiliary Equipment Mounted by the
side of ACB
• Effective utilisation of space
Separate Chambers for Busbars,

CABLE ALLEY:
The CBC is accessible from the rear
of the panel.
It is completely isolated form the
busbar zone and the ACB
compartments.
There is adequate space for
termination of aluminium cables.
Both TOP or BOTTOM cable entries are
possible. The wide cable alley facilitates
termination of a large number of cables.
The shrouded link work ensures
complete safety in the cable alley. The
link arrangements are specially
designed for multi-tier configurations
To check on unauthorised access to the
cable alley a special key is required for
opening the cable alley door.
BUSBAR SYSTEM:
Interleaved Busbar System :.
Only QSCPL offers the unique and innovative
interleaved busbar
Concept:
In the conventional busbar system, conductors
of each phase are together. At higher current
ratings in each phase, more than one flat of
busbars are provided . These flats are placed
quite close to each other. As a result of the
skin effect proximity effect, current
distribution in each of the same phase is
uneven. It also results unequal temperature
rise in different phases
At higher currents increase in cross area of
conductors does not yield proportionate
increase in the current carrying capacity the
busbars. The interleaved busbar system offers
a cost effective sol
