why choose
Sandwich bus duct
Compact structure, saving significant space
Utilizing a “sandwich” structure, there are no air gaps between the conductors, which are tightly stacked and wrapped in insulating material.
Extremely low voltage drop and high transmission efficiency
Due to the close arrangement of the conductors, the inductive reactance of the line is extremely low, resulting in a significant reduction in impedance.
Superior heat dissipation performance
The dense structure directly conducts heat to the metal shell through the insulating material. The overall heat dissipation of the dense busbar is more uniform, and temperature rise control is superior.
Extremely strong short-circuit resistance
It can withstand extremely high short-circuit current surges without deformation, ensuring high reliability for industrial power systems.
High safety, eliminating the "chimney effect"
Fireproof isolation: The internal solid physical structure has no air channels, preventing the spread of fire in the event of a fire, significantly improving safety.
Easy installation and maintenance
Installation only requires tightening a wrench until the outer nut comes off; no professional judgment is needed, making construction efficiency several times higher than that of cables.
