Unique Structure Design

Unique “serrated surface” design of extruded aluminum housing greatly improves the heat dissipation for the whole busway system.

Novel Conductor Structure

State-of-the-art welding processes with compact arrangement to create a true sandwich structure.

Sandwich Structure

Densely arranged conductors in the housing to achieve superior heat dissipation, lower temperature rise and eliminate the “chimney effect”.

Superior & Reliable Insulation

Both polyester film insulation and epoxy insulation (Class B) are available with exceptional electrical performance and superior mechanical strength. Environmental friendly materials are applied with certification by reputed international laboratory. The busway system is halogen-free with no toxicity emission in case of fire.

Conductor Sawing

High-speed sawing for a high sawing accuracy and smooth cut to reduce temperature rise at the busway joint.

Compact Design

The dimension of LV busway begins at 125mmx103mm for 400-630A ratings with very compact design. Bus plug is also compressive and dimension begins at 360mm×250mm×255 mm for 100A, giving more space for other equipments.

Unique Joint Design

Single bolt joint design to shorten the time of connection by 50% compared to the traditional design.
Double headed “break off” joint bolt to tighten the busway with just a common 16mm socket wrench. Belleville spring washers are adopted to ensure pressure evenly applied across the joint.

Temperature Rise Indicator

  • Joint insulator with a convex-concave groove edge provides an increased creepage
    distance.
  • Color-coded-temperature indicator applied at busway joint is to give an early warning when
    high temperature occurs at the joint.

Unique Error-proof Device

A bridge type joint is devised to prevent potential damage on busbar due to incorrect connection.
