What is a Busway?
Busway Systems comprise of a sophisticated and modern energy transmission and distribution system of modular structure, used in place of cabling.
What are Busway and Bus Duct?
Busway Systems could also be referred to as busway bus duct system.
What is a bar?
Busway Systems could also be called a bar duct in short.
Is there a busway price list?
The main components of any busway system are comprised primarily of metals like copper, aluminum and steel plate, as such busway costs and prices vary according to the current market prices of such raw materials. Therefore, there is no applicable price list. The total cost of any of our products is quoted in accordance with the project scope.
What is a busway tap off box used for?
It is the supply point of power to any machinery, equipment or switchboard on the plug-in connection of the busway system.
Why should busway be preferred? What are its advantages?
The advantages of a busway system are a physically well protected and modular structure, lowest possible voltage drop, increased product lifespan, high levels short circuit resistance, high levels of fire resistance, including no release of toxic gases (halogen free), ease in designing and redesigning of facilities, modern look, smaller electrical footprint and no need for bending radius, ease of maintenance and installation, low installation cost and overall cost efficiency.
At which distances should busway suspension systems be used?
In horizontal runs of the busway systems, suspension should be provided every 5 feet or 1.5 meters. In the case of vertical distribution installations, the system should be affixed to the floor slab for each story.
What should be the spacing between adjacent busway runs?
This topic is described in detail in the application sections of the technical catalogues.
How is a busway insulation test conducted?
It is done by using a Megger insulation test instrument. Before busway systems are commissioned, they should strictly pass through insulation tests and relevant commissioning procedures should be implemented.
Could the mainframe of the busway be used as ground conductor?
The mainframe (body) of any busway which is duly tested, certificated and manufactured according to UL, IEC and TS-EN standards can be used as ground conductor (protection circuit).
Are busway conductors tin-plated?
Busway conductors (aluminum and copper) should be tin or silver plated based on the application.
What is epoxy coating?
Epoxy coating is an insulation material used on the KX series busway systems manufactured by EAE, which is highly durable, and incorporates the premium features of insulation, fire-resistance and over-heating resistance.
Which conductor material is used on busway systems?
Busway systems have two conductor options, aluminum and copper. Aluminum is often preferred because of its reduced weight and its cost-efficiency. Copper is preferred when voltage drop, and busway size are of high importance.
Is any busway fire-resistant?
Busway systems which are duly tested, certificated and manufactured according to IEC 60331-1 and BS 6387 standards incorporate specifications like flame retardation, non-inflammability as well as non-emission of any toxic gases in case of fire (halogen free). The KX series premium design compact busway systems are capable of sustaining their functions for 3 hours in the case of fire generating heat at 830.0C temperatures.
What is a dilatation (expansion) module?
This is a flexible module used in busway runs where the length is in excess of 120 feet or at block passages of large-sized building structures. This allows for busway expansion, and contraction.
What is an offset module?
This is a module made as a combination of two turning modules, enabling the changing of the installation height or position of the busway system
Do you provide project design services?
Yes, we provide free Project design services. If you would like assistance with a project please click here
Is any busway system paintable?
Provided the color code prior to the manufacturing process, the busway system can be supplied with a painted finish. Painting on site after production is not advisable.
What are cable ducts, cable trays or wire ways?
Cable ducts, cable trays and wire ways are made to fix and support the laying of insulated cables for power distribution and data communication in and around building structures. They comprise modular lengths which are joined together on site to support the cables.
How should cable ducts, cable trays and wire ways be stored?
Details and particulars with respect to the storage of cable ducts, cable trays and wire ways are provided in our technical manual. They should be stored in a well-ventilated environment, protected against water and humidity.
What is E-30/E90 test?
This is an international criteria requiring that functional integrity is ensured in case of fire. Its basic objective is to ensure that functional sustenance of vital systems for human life such as lighting, elevator and announcement systems are maintained in case of any fire. Considering that the cabling in respect of the aforesaid systems are made through and over cable carrying systems, it is seen more clearly how essential it is that the latter systems enable functional sustenance. The test therefore is carried out inside a special test oven that can be heated-up in accordance with a Standard temperature-time curve. Depending on maintaining and sustaining the functionality of cabling systems, E30-E90 grades are prescribed and these are mandatory for the use at low voltage facilities not exceeding 1kV as a standard.
What is a pre-formed duct (pre-formed cable duct)?
This is a duct type where strength is enhanced through the pre-forming of each and every opening on the duct.
Could pre-formed ducts be thinner but yet stronger?
Yes, a stronger construction is obtained when using thinner steel plated on pre-formed ducts.
Are cable ducts fire-resistant?
Any cable duct passing the E30-E90 test and properly assembled is fire-resistant.

What is an under-floor socket box?
For those users utilizing screed installation ducts, under-floor busways and piping equipment providing mains supply, UPS energy outlet, or telephone-data and such similar connection outlets.
What is un under-floor cable duct?
Has the same meaning as under-floor duct system.
What is an under-floor box?
This is an installation item used under a raised floor or screed concrete system enabling connection or providing outlets.
What is a trolley busway?
Trolley busway supplies power to moving machinery systems like a mobile crane or machines moving on a line, ensuring power connection from a moving power supply trolley picking up power along a fixed busway system.
What is a hoist busway?
Has the same meaning as a trolley busway.
