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 possibil ity 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 flexibil ity for any change in distr ibution 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 distr ibution of loads are envisaged.

Standards & SpecificationE q u i p m e n t i s d e s i g n e d f o r l o w v o l t a g epower d i s t r ibu t ion as per I EC 439 (Pa r t 2 ) ,IS 8623 (Part 2).

Bustrunking enclosure is made from cold rolled steelsheet 1.6mm (16 SWG) with anti corrosive coating andfinally epoxy polyester powder coating of flint greyshade (RAL 7032).

As a standard practice the degree of protection isIP-52 for all ratings. Equipment with IP54 protection canbe supplied at extra cost.

Busbars in CBC type are made of 99.9% pure copper,ETP grade, whereas in CBA type, busbars are made of63401 WP grade aluminium alloy. Busbars are with fullround edges for easy insertion and removal of plug-in 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-in-pointsLow cost, flexible & safe distribution systemeliminates the requirement of separate distributionLT panel.

Salient Features of Compact Trunking

Small, compact and rigid construction.

Automatic polarity maintained throughout thesystem during installation.

Pleasant Light Grey Powder coated finish on rustproof enclosure.

Inside the bus trunking, busbars are supported atever y 250 mm for r ig id and shockproofconstruction.

Busbars in enclosure are held tight, and cannoteasily slide even in vertical runs when used as risingmains.

Riveted construction adopted for tamper-proofsystem.

Busbar Trunking System

System can be mounted edgewise or flatwise,horizontally or vertically in any direction with allkinds of bends, tees and crosses.

Un-drilled busbars of two sections can be joinedtogether by Joint Clamp using HTS bolts.

Extra safe cable connection in plug-in-boxeswithout additional cable support.

Tap off points are fully shrouded to prevent anyaccidental contact. They are further closed bynondetachable plastic covers.

Plug in boxes can be easily mounted, ensuring100% automatic polarity. Earth contact makes firstand breaks last.

4 pole isolator is provided in plug-in-boxes upto125A for extra safe connection on live bus trunking.

All plug-in boxes are COMPATIBLE with all ratings ofbus trunking.

Two sect ions can be eas i l y i so la ted fo rmaintenance and inspection in installed conditionwithout dismantling or removal of any section.

Both sides of bus trunking can be used withprovision of 4 tap off outlets per meter. (2 no’s. oneach side)

Safe, easy and quick plug-in / plug-out possible onlive bus trunking.

Considerable saving in installation and operationalcost. SYSTEM IS MAINTENANCE FREE.

System is totally reusable, easy to dismantle,reinstall and extend. Each section can beindividual ly replaced or dismantled withoutdisturbing other sections.

Fire barrier provision with F & T rating for 2 hourscan be provided as per requirement for floor andwall crossings (Refer UL1479).

Temperature rise on enclosure for all ratings is 25oCmax. for safety of operators

High dielectric strength and insulation levelmaintained even in hot and humid condition byuse of high impact, f lame retardant, non-hygroscopic insulators made of F-class material‘NORYL’

Plug-in boxes with MCCB and SFU can be providedwith door interlocking and interlocking with bustrunking to ensure “Plug-in” and “Plug-out” possibleonly in ‘OFF’ condition.
