Busduct Application & Advantages

Typically for building projects, cables form 20-25% of the capital cost for electrical infrastructure. Busducts are set to replace electrical cable in the future as requirement for network and distribution modularity is growing day-by-day.

Busduct provides an alternative means of conducting Electricity.

Busducts are 30% more expensive than cables; and hence in current scenario would increase electrical infrastructure cost by 6-7%.

Current Application for Busducts:

  • are increasingly getting used for single consumer applications i.e. HT billing

  • cannot be used for buried power transfer i.e. can't be used in buried trenches too

  • increasingly being used for:

  • vertical transmission in high-rise building, with multi-users

  • between transformers / DG & main LT panel

  • between main LT panel to sub-main distribution panels / boards

  • applications with high cable nos. e.g. Data Centre, IT Buildings

Structurally, a Bus Duct is a sheet metal duct containing either Aluminium or Copper Busbars [metallic strips or bars that conduct a substantial electrical current] in a grounded metal enclosure.

Advantages & Benefit:

Design: compact design,[requires less space] through which compressed flat conductors can pass through the enclosure.

Heat Absorption: Since the design is compact & has a metal casing with well-defined surface, busbar's can absorb heat generated while transmissions & distribution of electricity in the walls of the enclosure.

Flexibility: easily modifiable & can also be relocated without much of a capital expenditure.

Cost Savings: can be mounted easily compared to cables & incurs a lesser cost of installation than traditional cables.

Better Resistance: rigid design elements & a minimum distance between the conductors & it's have a thin and flat tire which helps in optimal distribution of density of current which in turn reduces the induction of resistance.

Reduced Loss of Energy: loss of energy due to transmission and distribution is lower, It's also have a limited growth of reactive power to operate compared to cable systems.

Lower Electromagnetic Field: compact design and the steel shell, hence comparatively lower electromagnetic field is created around a Busbar as compared to a cable.

No Dependency on Length: difference of length is eliminated since they have the parameters of active and inductive resistance to ensure that the load on each phase is equal.

Ease of Distribution: easy, efficient and safe distribution of line with the junction boxes in places where they are required. Moreover, the location data junction boxes can be changed whenever and where-ever in the future.

Standard Cells: fully certified standard cells are an integral part of busbars which is meant to eliminate human error.

Safe and Secured: fitted with a steel casing and cannot be damaged by rodents as compared to cables.
