Compartmentalised Design
• Multi - Tier Arrangement
• Vertical Dropper Concept Permits
• 1 / 2 / 3 tier arrangement for ACBs.
• Upto 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, Droppers Auxiliary 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 L&T offers the unique and innovative interleaved busbar system.
Concept
In the conventional busbar system, conductors of each phase are grouped together. At higher current ratings in each phase, more than one flat of busbars are used. These flats are placed quite close to each other. As a result of the skin effect and proximity effect , current distribution in each flat of the same phase is uneven. It also results in unequal temperature rise in different phases.
At higher currents increase in cross-sectional area of conductors does not yield proportionate increase in the current carrying capacity of the busbars. The interleaved busbar system offers a cost effective solution.

        CONVENTIONAL SYSTEM                         INTERLEAVED SYSTEM

Advantages of Interleaving:
• Improved current distribution and lower temperature rise.
• Reduction in electrodynamic forces during short circuit.
• Low watt-loss and direct saving in energy. • Enhanced life of insulation.
Other Features of Busbar System :
• Totally insulated busbar and dropper system.
• Reduction in electrodynamic forces during short circuit.
• Low watt-loss and direct saving in energy.
• Enhanced life of insulation.
Heat shrunk PVC sleeving
Eliminates air pockets
Acts as secondary insulation
Eliminates the risk of faults due to shorting by vermin
'CLICK - FIT' Type joint shrouds
Ensures absolute protection for operators
                                                                   Allow access to nuts & bolts for maintenance
                                                                   Restrict arc travel to the zone of initiatio n.
                                                                   Moulded Busbar Support System :
                                                                   • Moulded from fibre glass reinforced thermosetting plastic which
                                                                   has higher mechanical strngth compared to conventional support material
                                                                   • Ribbed construction prevents tracking caused by dust accumulation.
                                                                   • Excellent arc resistant & anti tracking properties.
                                                                   • Profile of support increases creepage distance .
