HP Bus Duct System

T2 HP Fire Resistance Bus Duct System

The “bus-duct” system provides an effective and efficient supply of electricity. Either Copper or aluminum is used as the conductor of bus duct that is insulated and enclosed completely for protection against mechanical damage and dust accumulation. The system comprises feeder bus duct, plug-in bus duct, flatwise elbow and tee et al, making the system safe, economic, neat and enduring.

The system meets the requirements of wiring in high-rise buildings and large-scale industrial plants and it applies to IEC 439-2, and NEMA BU1.
