Bus duct what is

Busbars are generally supported on high creep porcelain insulators are high quality epoxy resin cast insulators of suitable rated voltage These Segregated phase busducts are commonly used in Medium voltage applications with rated voltages from 3. Widely used as an interconnection between transformer to Switchgears, Switchgear to switchgears and also sometimes used as link between small capacity generators and main transformers under 3 phase, 3 wire configurations.

As the name implies, there is no metallic barriers between phases These busducts are relatively compact in comparison with segregated phase bus since the same are generally used for low voltage applications and thus needing much lower electrical clearances between phases and phase to earth. Our technology solution is one of the best in the world. Busway has a lower voltage drop than cable and conduit due to the solid phase bars which results in lower impedance.

Perhaps most importantly, installation of cable and conduit is typically more labor intensive than installation of busway, and the higher the ampere rating of the system, the greater the labor differential between the two approaches. Non-segre gated busway has copper phase bars located in one enclosure separated by air and epoxy insulation.

Environmental ratings include indoor, outdoor and dust tight. Housing or enclosure material can vary from aluminum, steel or stainless steel. Capable of providing both medium and low voltage solutions, non-segregated phase bus duct is well suited for harsh environments.

Common market segments: electrical utilities, petrochemical sites and heavy industry. Non-segregated phase bus duct is used in applications up to 38 kV and A. Sandwich-style busway has phase bars stacked together inside a non-ventilated aluminum or steel enclosure. This busway can be indoor, sprinkler proof or outdoor rated and can be used for delivering power between gear using feeder pieces.

Additionally, tap-off locations can be provided on the busway itself. This style is called plug-in busway and is typically used to power equipment below the busway. Capable of providing high ampacity with equally high short-circuit withstand ratings, sandwich-style busway is a cost-efficient solution in multiple markets.

Common market segments: commercial construction, general and heavy industry and data centers. Sandwich-style busway is used in applications up to V and up to A. Track busway is a continuous rail design where tap-off boxes can be installed or removed nearly anywhere along the busway system.

The tap-off boxes come equipped with cord whips and fixed receptacles allowing for power distribution to equipment below the busway. Capable of providing low voltage and ampacity solutions with simple onsite reconfigurations, track busway is common in data center markets but is also very effective in laboratories and warehouse applications. Common market segments: data centers, machine shops and labs.

Track busway is rated for indoor use and is available up to A and V. Busbar trunking systems are gradually becoming more commonplace as a power distribution system due to the several key advantages they have, namely:. Learn more: Advantages of Busbar Trunking System. Busbar trunking systems distribute power through tap-off units installed along the trunking of the system, and individual systems can come in various voltages such as low, medium and high voltages depending on the needs of the customer.

Tap-off units can simply be included in the special socket for the power bus bar or a subnet via the distribution panel , or directly to the machinery.

Tap-off units can also be mounted directly under the load without stopping, for example, the production process. Mounted vertically, the same busbar can be used to line fare with tap-off units on the floors. The use of protective devices fuses, circuit breakers with fuses or circuit breakers, circuit breakers distributed along the length of the busbar trunking system reduces the need for cables from the tap-off unit to the machinery.

High-voltage busbars carry energy directly from point A to point B; usually the transformer or switchboard to the switchboard. However, if necessary, machinery can be connected to the busbar trunking and the tap-off units in any part of the track.

Aluminium and copper busbars both have their advantages and disadvantages, which make them suitable depending on the needs of the customer. However due to its lower conductivity of electricity based on volume compared to copper, aluminium busbars generally have to be larger in order to have the same level of conductivity. Copper busbars are far more conductive than aluminium, and because of that they tend to be more compact.

However, the price of copper is volatile, and due to its weight it requires more support and therefore more labour costs. Learn more: Copper vs Aluminum Busbar. It is a distribution cable system for outdoors, humid and dusty places, and places frequently exposed to chemical materials.
