What is a Plug-in Type Sandwich Busway?

Fenghua Electric Plug-in Type Sandwich Busway (Dense Type) is designed to solve common low-voltage distribution challenges: high energy loss, difficult installation, and limited space. The busway features:

High-purity T2 copper conductors for excellent conductivity, reducing power loss by over 30% compared to aluminum.

Sandwich dense-stacked structure with copper-insulator-copper layering, ensuring compactness, superior insulation, and safe operation.

Plug-in modular design for flexible installation, easy maintenance, and rapid expansion without major system changes.

Comprehensive protection (IP54 standard, optional IP65/IP66), corrosion resistance, and compatibility with diverse indoor and outdoor environments.

Rated for ≤1000V low-voltage systems, with currents from 630A to 2500A, this busway supports industrial plants, commercial buildings, data centers, hospitals, and high-reliability public infrastructure.
