Main Features
1. Variable shapes of bus duct
Horizontal Elbow (HL) Duct
Horizontal jointing used to connect bus ducts at a right angle
Vertical Elbow (VL) Duct
Vertical jointing used to connect bus ducts at a right angle
Horizontal Offset (HZ) Duct
Jointing unit used to adjust route position horizontally by the smallest amount possible
Vertical Offset (VZ) Duct
Jointing unit used to adjust route position vertically by the smallest amount possible
Vertical Tee (VT) Duct
-Vertical jointing unit used to branch bus duct in three directions
※Horizontal Tee (HT) Duct also available.
※Horizontal jointing unit is used to branch bus duct in three directions.
Expansion Duct
-Duct used to absorb thermal expansion and contraction of bus ducts
-Used in routes with long straight sections
Plug-In Units
-Plug-in branch boxes used to branch load from bus ducts
2. Vertical Supports
Distance between Vertical Supports
The distance between vertical supports is permitted to be up to 6m according to electrical equipment regulations in Japan (check and conform with the regulations in your country), but we recommend providing floor support on each floor. In cases where floor height is 4m or higher, we recommend installing intermediary sway-bracing systems.
※Number of support bolts will vary depending on the capacity of the bus duct.
3. Horizontal Supports
Distance between Horizontal Supports
The distance between horizontal supports must be no less than 2m.
Additionally, be sure to install earthquake-proofing supports at appropriate intervals according to your construction guidelines and planning for facility earthquake proofing.
