600V Non Segregated Phase Busway

The defining characteristic of an Non Segregated Phase Electric Busway is that all three phase conductors are housed within a single metal enclosure. There are no metal barriers between the phases (unlike phase segregated bus duct). The conductors are separated by air gaps and supported by high-strength, track-resistant insulators.

Key Features：

• Fully Insulated Conductors: To prevent phase-to-phase faults caused by environmental factors (dust, moisture, or vermin), the copper or aluminum bars are typically covered with high-dielectric heat-shrinkable sleeves or fluidized bed epoxy coating.

• Non-Magnetic Enclosures: For high-amperage systems (typically above 2500A), the housing is made of Aluminum Alloy. Being non-magnetic, it eliminates hysteresis and eddy current losses, preventing the enclosure from overheating.

• Robust Insulation Support: Conductors are held firmly by porcelain or epoxy resin insulators designed to withstand the massive mechanical stresses of a short-circuit event.

• All-Weather Protection: For outdoor installations, Non Segregated Phase Electric Busway systems include sloped roofs, breathers, and integrated Space Heaters to prevent condensation and maintain dielectric integrity.
