Busbar Trunking System
Busbar trunking system in compact design is the most efficient, safe and ideal system for electricity supply
to industrial installations and high rise structures, offering a wide current range from 125A to 2000A in
type CBC (Copper conductor) and 160A to 1250A in type CBA (Aluminium conductor) with possibility of
feeding loads upto 400A with standard plug-in boxes. The system has provision of 4 Plug-in outlets per
meter, which can be fitted quickly and provide total flexibility for any change in distribution layout at
a later stage. The system has been designed especially for installations and projects where power supply
has to be made available rapidly.
These are most suitable for applications where exact location and
power consumption is not sure and possible changes in physical distribution of loads are envisaged.
Standards & Specification
Equipment is designed
power distribution as per
IS 8623 (Part 2).
for
IEC
low
439
Bustrunking enclosure is made from cold rolled steel
sheet 1.6mm (16 SWG) with anti corrosive coating and
finally epoxy polyester powder coating of flint grey
shade (RAL 7032).
As a standard practice the degree of protection is
IP-52 for all ratings. Equipment with IP54 protection can
be supplied at extra cost.
Busbars in CBC type are made of 99.9% pure copper,
ETP grade, whereas in CBA type, busbars are made of
63401 WP grade aluminium alloy. Busbars are with full
round edges for easy insertion and removal of plugin boxes.
Advantages of Compact Design
„
Compact size and easy installation
„
Unmatched reliability
„
Flexibility leading to reduced costs
„
Polarity errors are totally eliminated
„
Low impedance & hence low voltage drop
„
Improved thermal characteristics.
„
Provides distribution & protection through Plug-inpoints
Low cost, flexible & safe distribution system
eliminates the requirement of separate distribution
LT panel.
„
„
System can be mounted edgewise or flatwise,
horizontally or vertically in any direction with all
kinds of bends, tees and crosses.
„
Un-drilled busbars of two sections can be joined
together by Joint Clamp using HTS bolts.
„
Extra safe cable connection in plug-in-boxes
without additional cable support.
„
Tap off points are fully shrouded to prevent any
accidental contact. They are further closed by
nondetachable plastic covers.
„
Plug in boxes can be easily mounted, ensuring
100% automatic polarity. Earth contact makes first
and breaks last.
„
4 pole isolator is provided in plug-in-boxes upto
125A for extra safe connection on live bus trunking.
„
All plug-in boxes are COMPATIBLE with all ratings of
bus trunking.
„
Two sections can be easily isolated for
maintenance and inspection in installed condition
without dismantling or removal of any section.
„
Both sides of bus trunking can be used with
provision of 4 tap off outlets per meter. (2 no’s. on
each side)
„
Safe, easy and quick plug-in / plug-out possible on
live bus trunking.
„
Considerable saving in installation and operational
cost. SYSTEM IS MAINTENANCE FREE.
„
System is totally reusable, easy to dismantle,
reinstall and extend. Each section can be
individually replaced or dismantled without
disturbing other sections.
„
Fire barrier provision with F & T rating for 2 hours
can be provided as per requirement for floor and
wall crossings (Refer UL1479).

Salient Features of Compact Trunking
„
Small, compact and rigid construction.
„
Automatic polarity maintained throughout the
system during installation.
„
„
Pleasant Light Grey Powder coated finish on rust
proof enclosure.
Temperature rise on enclosure for all ratings is 25 o C
max. for safety of operators
„
„
Inside the bus trunking, busbars are supported at
ever y 250 mm for rigid and shockproof
construction.
„
Busbars in enclosure are held tight, and cannot
easily slide even in vertical runs when used as rising
mains.
High dielectric strength and insulation level
maintained even in hot and humid condition by
use of high impact, flame retardant, nonhygroscopic insulators made of F-class material
‘NORYL’
„
Plug-in boxes with MCCB and SFU can be provided
with door interlocking and interlocking with bus
trunking to ensure “Plug-in” and “Plug-out” possible
only in ‘OFF’ condition.
„
Riveted construction adopted for tamper-proof
system.
