China M7 Compact Busbar System (315-6300A) - Efficient Power Transmission Solutions for Factories | Renyun Suppliers
Housing
Aluminum or steel housing with electrostatic coating, RoHS-compliant.
Conductors
Conductors can be silver, copper, or tin plated based on requirements.
Insulations
Insulated with "H class" polyester film or epoxy coated on conductors.
Tap-off Boxes
Plug-In Unit
Circuit breakers from all brands and configuration requirement can be optionally selected to meet the branch circuit power supply design with rated currents ranging from 16A to 630A.
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.

Applicable Environments and Use Cases
Frequently Asked Questions (FAQ)
What materials are used for the housing and conductors of the compact busbar system?
The system features an aluminum or steel housing with RoHS-compliant electrostatic coating. The conductors can be silver, copper, or tin-plated according to customer specifications, insulated with Class H polyester film or epoxy coating.
What are the rated current options for the Tap-off / Plug-in boxes?
The plug-in units can accommodate circuit breakers from all major brands with configuration options tailored to meet branch circuit design requirements, supporting rated currents ranging from 16A to 630A.
What is the difference between horizontal and vertical busbar applications?
Horizontal applications deliver power directly from transformers or generators across end-use zones. Vertical applications serve as rising mains across multi-story buildings, delivering power to each floor while incorporating fire-rated sealing and integrated protective devices.
What protection ratings (IP) are available for this compact busbar system?
The system offers optional IP ratings of IP54, IP65, and IP66 to accommodate varying indoor and industrial environmental protection demands.
Why choose a compact busbar system over conventional cables?
Compact busbars require significantly less space, offer lower voltage drop, higher short-circuit resistance, superior heat dissipation, better fire and seismic resistance, and enable faster installation via a single-bolt joint system.
Which industrial environments are best suited for compact busbar installation?
They are suitable for high-demand facilities including data centers, automotive plants, textile & steel factories, high-rise buildings, shopping malls, hospitals, hotels, and oil & gas facilities.
