6300A Sandwich Busway

This 6300A compact busbar trunking is dedicated heavy-duty power distribution equipment for ultra-high current applications, engineered for high-power supply scenarios including AI computing clusters, large-scale energy storage power stations and heavy industrial plants. It features an iconic three-row layered housing structure with a neat, streamlined silhouette and straight minimalist lines, delivering a distinct industrial aesthetic.

The housing is extruded from high-strength aluminum-magnesium alloy with matte black electrostatic powder coating, offering excellent corrosion resistance and anti-dust accumulation performance. Three parallel independent cavities are arranged in layers and joined into an integrated enclosed housing via side fastening bolts, presenting a well-structured, symmetrical layout with superior visual tidiness. Beyond creating a layered appearance, the three-row design expands heat dissipation channels to resolve heat buildup during long-term high-current operation. The lightweight housing also eases on-site hoisting and installation work.

High-conductivity electrolytic copper is adopted as the internal conductor, delivering a stable rated current carrying capacity of 6300A. Silver plating is applied to joint contact surfaces to effectively reduce contact temperature rise. Class B high-temperature resistant insulating supports are installed between phases to meet required insulation voltage withstand standards, enabling continuous full-load long-term operation. The product achieves IP54/IP65 protection ratings, suitable for diverse indoor and outdoor working conditions.

The full product range has passed complete type tests in compliance with IEC international electrical standards, supporting three-phase four-wire and five-wire power distribution systems. Flexible wiring is available with matching accessories including tap-off boxes, plug-in units and various elbows. Integrating neat three-row appearance, lightweight high-protection housing and low-loss high-current conductors, this product balances architectural aesthetics, operational stability and energy efficiency, serving as the top choice for ultra-high power distribution projects.

This project involves the power distribution renovation of the power room in a large industrial park. The site is equipped with multiple high-power transformers, resulting in an extremely high overall power load with a peak total supply current of 6300A. Our three-row compact busbar trunking is adopted as the main power transmission carrier, which perfectly fits the application scenarios featuring high current and spacious power rooms.

The power room of this project boasts ample floor height and abundant overhead laying space, without spatial constraints such as narrow suspended ceilings or compact pipe shafts, which aligns well with the structural characteristics of the layered three-row busbar. The busbar system is entirely installed overhead via hanging brackets, with three independent conductor rows arranged neatly in parallel. Supporting vertical elbows and wall-penetrating units are used to complete the full connection from transformers to low-voltage cabinets. The wiring layout features distinct layers, facilitating routine inspection and maintenance in later stages.

The lightweight aluminum-magnesium alloy housing of the product greatly reduces the load-bearing pressure of overhead hangers. The layered cavities form unobstructed heat dissipation channels. Even under continuous full-load power transmission at 6300A for long periods, the temperature rise of conductors and joints remains steadily controlled. With an IP54 protection rating, the product adapts to the ordinary indoor environment of power rooms and delivers effective dustproof and moistureproof performance. The complete busbar system is equipped with standard connecting joints and fixed support hangers; its modular splicing structure shortens on-site construction duration and cuts civil renovation costs.

To address the demand of high-load power supply, the three equal-current rows evenly distribute the transmission load, eliminating risks of overheating caused by overload in single-channel busbars, and meeting the round-the-clock uninterrupted power supply requirements for park production and supporting facilities. This project case fully verifies that our three-row high-current busbar trunking stands as the optimal solution for power distribution projects in power rooms, computing centers and large factories characterized by heavy power loads and sufficient laying space, balancing stable power supply, convenient construction and easy post-operation maintenance.

To enable customers to visually and directly verify product materials, housing craftsmanship, conductor structure and assembly details, our company has formulated a standardized sample service policy covering all three-row high-current compact busbar trunking products.

This product is assembled by combining three single-row busbar units with identical current-carrying specifications. The current-carrying capacity of a single row matches the performance parameters of a single channel within the complete three-row assembly. Accordingly, samples are uniformly supplied as single-row busbar trunking of the same specification, which fully replicates all core craftsmanship including conductor cross-section, housing structure, insulation components and joint plating, without compromising customers' technical verification and solution evaluation.

The standard sample length is 500 mm by default, which fully displays key structures such as end flanges, housing splicing joints and internal insulation supports. Custom-length samples are available upon customers' requests for special dimensional testing or on-site demonstration, with quotations adjusted according to the actual material length used. All samples are brand-new factory-standard components, manufactured with the exact same aluminum-magnesium alloy housing, high-conductivity conductors, Class B insulation parts and tinned joint accessories as mass-delivered products, and maintain consistent electrical and protection performance indicators with volume production goods.

Due to the high raw material costs of busbar conductors and aluminum alloy housings, samples are charged at the corresponding material cost; free samples are not provided. After customers place formal bulk purchase orders, both parties may negotiate terms for deducting the sample fees, with the specific deduction ratio and deduction timing subject to the commercial contract. Sample logistics expenses shall be borne by the customer. Prior to shipment, we will provide a sample specification list and material description for customers' on-site inspection and preliminary laboratory type testing.
