Tai Sin Busway Unique Features
Tai sin Electrical Busway Unique Structure Design

Unique Structure Design

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

Novel Conductor Structure

Novel Conductor Structure

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

Robust 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

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.

Compact Design

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.

99.9% Purity Copper Conductor

99.9% Purity Copper Conductor

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

Unique Error-proof Device

Unique Error-proof Device 

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

Unique Joint Design

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.

Predictive Temperature Rise Indicator

Temperature Rise Indicator

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

Safe Plug Outlet and Busbar Plug

  • Both outlet phase tabe and plug stab fingers are fully silver-plated
  • The bus plug has complete safty interlock mechanism to ensure electric safty
  • The plug outlet protection module is embedded with waterproof silicone rubber, up to IP54
  • Up to 10 plug outlets can be installed every 3 m of straight length busway
