Now days, Busway system is widely used in commercial, residential and
industrial area to deliver the electricity, especially massive power current
required places such as power plant, computer system and UPS system.
Most of application is AC 3 phase system, but it can be applied in DC
electric system.
Our Busway system is possible of high power transmission up to 7500A
(AC) / 10000A (DC), so it can be best solution in DC power system as well.

■ De-rating for High Ambient Temperature
For higher ambient temperature exceeding 40 , the de-℃
ratings should be required by applying the multiplier,
according to NEMA BU.1.1.
However, LSC ASTA & KEMA Certified Ex/Ez-way busduct
can be applied up to 55 without any de-rating. Also in the℃
case of using mica insulation as Ef-way, the thermal stability
of LS busduct system can be easily upgraded.
