This design extends the contact surfaces outside of the busduct casing and into the plug-in outlet, maintaining a true sandwich design throughout the entire busduct length for both feeder and plug-in busduct. This will eliminate the need to seperate or flare the conductor bars at Polyester Tape the plug-in opening. Fiberglass sheets Teflon Coated Fiberglass Maintaining a true sandwich design eliminates Tin Plated Copper potential pathways for the propagation of flame, smoke and gas through the busduct casing, com- monly referred to as the ‘chimney effect’. The sand- wich structure with low impedance ensures low voltage drop and thus enables the cost-effective Shown is a section of Lectro bus duct insulation con- transmission of large amount of power even at long sisting of two different insulation materials. Conduc- distances. tors are insulated with Teflon Coated Fiberglass films (10 mil* thickness, 5000 V, 250 OC) and layered with fiber glass sheets. After assembly all the bars are wrapped together with polyester tape. The result is an insulation system that is virtually impervious to the stress of normal operation. The insulation system is tested after assembly with 2500 volt for one minute. This test is intended to confirm the integrity of the in- sulation system and helps ensure the highest qual- ity bus duct possible. All the insulation materials are rated as class H (minimum) non-flammable hence no internal fire barrier is needed. Upon request the bars can be insulated with cycloaliphatic epoxy resin class B 130OC. 10 Introduction Design & Construction Lectrobar is constructed with extruded aluminum Hence integral housing ground is standard and provides profile.
