Applications
Horizontal Applications
The power busbar system is a modular solution for electrical transmission and distribution, featuring insulated copper or aluminum conductors housed within a protective enclosure. Installed horizontally, the system delivers power from sources such as transformers, generators or distribution panels, and supplies electrical energy to end-use areas through tap-off units positioned along its route.
Vertical Applications
When installed vertically, the busbar system serves as rising mains, allowing tap-off units to supply power to each floor. Fire-rated sealing solutions can be applied where the busway penetrates building slabs. Protective devices including fuses, switch-fuse units, or circuit breakers may be integrated along the vertical run, minimizing the need for oversized distribution boards and reducing the amount of conventional cabling within the building.

Frequently Asked Questions
Q What materials are used for the conductors and housing in this system?
The housing is manufactured from aluminum or steel with RoHS-compliant electrostatic coating. The internal conductors can be customized with silver, copper, or tin plating depending on engineering requirements.
Q What is the rated current range available for tap-off plug-in units?
Plug-in units accommodate circuit breakers from all major brands with current configurations rated from 16A up to 630A to support diverse branch circuits.
Q How does the compact busbar system perform in vertical installations?
When installed vertically as rising mains, it distributes power floor-by-floor with fire-rated slab sealing and built-in circuit protection, significantly saving installation space over traditional cabling.
Q What ingress protection (IP) levels are available?
The busbar system provides optional protection ratings including IP54, IP65, and IP66 to ensure high reliability across demanding environmental conditions.
Q What type of insulation is applied to the conductors?
Conductors are insulated with high-grade "H class" polyester film or epoxy coating, offering high thermal resilience and superior dielectric strength.
Q Why is the compact busbar system preferred over conventional cables?
It provides lower voltage drop, enhanced short circuit and seismic resistance, superior cooling, and faster installation through its secure one-bolt joint design.
