Sandwich Bus Ducts, BBTs

The benefit of using bus duct can be seen in many ways. For starters, the job of quoting and estimation of the quantities of materials require can be determined quickly and accurately in a matter of time. The compact design allows for easy installation and in many cases, the equipment can be pre-assemble prior to delivery which is very much a time saver. The fact is that the material cost of bus duct trunking compared to cable is higher. But if the total cost of installation works, labour cost and the time saved are considered, the balance usually tips in favour of bus duct trunking. Advantages include: requires less manpower; time saving; easy for fault finding and maintenance work; and facilitates use of protective devices. Features: superior compact and maintenance free; 1.6 mm thick epoxy insulation by special extrusion machine; range ? 200 A to 6300 A in sandwich design in copper and aluminium both; copper conductor is tin electroplated along its entire length and aluminium conductors are silver coated at joints; overlapped jointing system; the joints are maintenance free one bolt joint system; up to 5 plug in holes can be provided in 3000 mm standard length spaced at 500 mm on both sides of BDS; expansion joints are required for >30 mtrs in bus trunking and > 90mtrs in case of rising mains; temperature rise permitted up to 55?C above an ambient temperature of 40?C at rated current; 200% neutral design; and high tech epoxy insulation.
