Electrical Bus Duct Solutions

What is a Bus Duct?

A Bus Duct is a prefabricated electrical distribution system used to transmit high currents from one point to another using enclosed conductors instead of conventional cables.

  • Conductors : Copper or Aluminium bars for current transmission
  • Housing : Metallic enclosure providing mechanical protection
  • Insulation: Ensures electrical safety and prevents short circuits

    How Bus Duct Systems Work?

    Bus duct systems distribute power through rigid, enclosed conductors that are assembled in modular sections, allowing efficient current flow, reduced power losses, easier installation, and simplified expansion compared to traditional cabling.

    HT & LT Busduct up to 33KV
    (indoor /outdoor type)

    Bus duct systems are designed to allow multiple outputs from them without any power loss. Our manufactured bus bar chambers need very little maintenance. We are one of the most reputed bus duct suppliers in India, delivering quality systems of any type, including segregated, LT (Low Tension), and MV (Medium Voltage).

    Q1: What is an electrical bus duct and how does it work?

    An electrical bus duct is a prefabricated power distribution system that carries current through copper or aluminium busbars enclosed in a metal housing. HTS Switchgear P Limited designs bus duct systems to replace long cable runs for high-current power transmission between transformers, panels, and distribution points in industrial and commercial facilities.

    Q2: What is the difference between bus duct and cable/cable tray?

    Bus duct is factory-engineered in fixed sections and bolted together on site, offering higher current-carrying capacity, lower voltage drop, and faster installation for high-amperage runs. Cable and cable tray systems are more flexible for routing around obstructions and cost less upfront, but require more field labour and space at higher current ratings — typically above 1200–2500A. HTS Switchgear P Limited helps clients evaluate which option suits their load and site conditions.

    Q3: What is the difference between busway and bus duct?

    The terms are used interchangeably in the industry. Bus duct refers to the individual prefabricated enclosure section carrying the busbars, while busway describes the complete assembled system - bus duct sections, elbows, tap-off boxes, and fittings - that together form the distribution run.

    Q4: What types of bus duct does HTS Switchgears manufacture?

    HTS Switchgear P Limited manufactures sandwich (compact) bus duct, air-insulated bus duct, plug-in bus duct with tap-off points for connecting loads along the run, and weatherproof bus duct for outdoor installations. Type selection depends on current rating, space constraints, and load-tapping requirements.

    Q5: What standards should an electrical bus duct comply with in India?

    Bus duct systems should be manufactured to IS/IEC 61439 for low-voltage switchgear and control gear assemblies, with type-testing for temperature rise, short-circuit withstand, and IP rating suited to the installation environment. HTS Switchgear P Limited builds all bus duct systems to these compliance standards.

    Q6: Does HTS Switchgears manufacture custom bus duct systems?

    Yes. HTS Switchgear P Limited designs and manufactures custom bus duct systems engineered to the client's load profile, current rating, routing constraints, and site conditions, rather than offering only standard off-the-shelf lengths.

    Q7: What is the typical cost of a bus duct system in India?

    Cost depends on current rating, bus duct type (sandwich, air-insulated, plug-in, or weatherproof), run length, number of tap-off points, and enclosure/IP rating. Because pricing varies by specification, HTS Switchgear P Limited provides project-specific quotations based on load and installation requirements rather than a fixed catalogue price.
