Industrial Busbar Trunking System

Busbar Trunking SystemThese straight bus duct run along the length of connection and the body of the bus trunking system.Types of straight busduct are:Feeder type: Straight busbar trunking unit with no tap off facility.Plug in type: Straight busbar trunking unit having tap off points on one or many faces.System Voltage :600V and up to maximum 1000V / 3P / 50 Hz or 60 Hz constructed in various configurations of 3 phase 3 wire or 3 phase 4 wire with or without 50% integral housing ground and separate earth bar. The earth bar (50% or 100%) can be installed. To counter excessive harmonic effects, 200% neutral can also be provided on request.Current Ratings :Wide range of current rating from 100A to 6300A for Copper Conductor and upto 5000A for Aluminium Conductors.Epoxy Insulation :All Busbars have Class H -180C standard epoxy coating as insulation material which provides 100% water proofing and high mechanical strength. This insulation has been tested in accordance with IEC 60-439-2 and BS 5486.Benefits of using epoxy coating as insulation:Withstands glitch and spikes in electrical system so that system is stable & runs reliably.Provides rooms for expansion/contraction during peak and off-peak hours to avoid tracking in surface of insulation.Capable of withstanding heat shock thus minimising chances of failure due to spark or excess heat.High mechanical strength so that insulation damage by accidental impact is reduced.High thermal conductivity to provide uniform distribution of heat, hence system runs cooler.Water and chemical resistant which makes it suitable for use in corrosive and humid environment.Horizontal / Vertical BusBars :All L&T Megaduct copper busbars are of high conductivity (IACS 99.98%) copper bar with high purity (>99.95%), or aluminum bars with conductivity >61%. All copper busbars are fully tin or silver plated and fully epoxy insulated.The busbars are tropicalised to withstand higher temperature rise of 50oC- 55oC.Standard lengths of 3M / 2M / 1M up to 0.45M. Other lengths will be made available as required.HousingL&T Megaduct Busbar Trunking have a rugged housing profile and provide the most efficient way to dissipate heat through conduction and natural convection. All housings are constructed from 1.6mm electrogalvanized steel sheet coated with oven baked polyester powder paint or epoxy coated powder which also provides maximum mechanical strength against electromagnetic stresses.
