DC Compact Busduct

Compact DC busbar trunking is a high-current, high-safety power transmission and distribution device specially developed for DC power distribution systems. It is applicable to mainstream DC power supply scenarios including new energy energy storage stations, photovoltaic power plants, data centers and DC charging piles. It can perfectly replace traditional cable wiring and resolve industry pain points such as high power loss in high-current DC transmission, messy wiring and difficult maintenance.

Adopting a compact stacked insulation structure and high-conductivity conductors with exclusive DC insulation encapsulation technology, the product features strong current-carrying capacity, low resistance loss and outstanding heat dissipation performance, enabling stable long-term continuous operation of various medium and high-power DC power supply systems.

Fitted with an aluminum alloy housing, the product boasts a compact structure and easy installation to greatly save power distribution space, while delivering excellent dustproof, moisture-proof and anti-corrosion properties for indoor and relatively humid complex working conditions. Optimized conductor layout and insulation system effectively eliminate risks of DC electric arcs caused by circulating current, overvoltage and overheating common in DC systems, greatly improving operational stability.

All products are manufactured in strict compliance with electrical industry standards and pass a full range of performance tests including voltage withstand, temperature rise, insulation and overload tests. Customization of non-standard current ratings and flange terminal structures is available. Featuring high safety, low energy consumption and easy maintenance, it serves as an efficient and reliable core power transmission supporting equipment for new energy DC power distribution projects.

Both compact DC busbar trunking and compact AC busbar trunking are compact and high-efficiency power transmission equipment featuring compact structure, easy installation and excellent protection performance, suitable for centralized power distribution projects. Nevertheless, they are designed for different power supply systems and have distinct differences in electrical characteristics, applicable scenarios and operational performance.

AC busbar trunking adapts to traditional power-frequency AC power distribution systems. As universal equipment for industrial plants, commercial buildings and building power distribution, it boasts mature technology and wide versatility, capable of realizing stable transmission and shunting of conventional power-frequency alternating current, and matching the AC connection conditions of standard high and low voltage switchgears available on the market.

DC busbar trunking is optimized and upgraded exclusively for new energy DC power transmission systems. Targeting the inherent characteristics of direct current such as zero frequency, absence of skin effect and high risk of electric arc generation, it adopts optimized conductor layout, insulation encapsulation and sealing structures. Compared with AC counterparts, it delivers more uniform current transmission, lower line loss and more stable temperature rise control under high-current working conditions, effectively eliminating safety hazards including DC electric arcs and circulating current interference. It fits new DC power distribution scenarios such as energy storage power stations, photovoltaic power plants, DC charging piles and data centers.

In terms of structural customization, AC busbar trunking mostly adopts standard three-phase four-wire or three-phase five-wire layouts with a high degree of standardized specifications. In contrast, DC busbar trunking supports dedicated positive and negative pole arrangements and can be customized non-standardly according to parameters of DC equipment for stronger adaptability. During long-term operation, DC busbar trunking achieves lower energy consumption and superior anti-interference performance, in line with the low-carbon and energy-saving power distribution demands of the new energy industry. Meanwhile, AC busbar trunking is more suitable for generalized and standardized construction scenarios of traditional power-frequency power distribution.

Our compact DC busbar trunking is equipped with complete and authoritative official qualification certifications, mainly including CQC product certification and a full set of type test reports. All qualifications are verifiable, authentic, compliant and valid, which fully guarantee product quality, operational safety and compliance for project bidding.

As China's authoritative safety certification for electrical products, CQC certification indicates that all electrical performances, safety indicators and material standards of our product have passed rigorous national inspections. It complies with the access standards for domestic engineering projects including new energy power distribution, energy storage and data centers, and enjoys high market recognition and universal applicability in engineering construction.

In addition, the product has passed comprehensive type tests conducted by authoritative third-party testing institutions, covering dozens of stringent test items such as insulation performance, voltage withstand level, temperature rise limit, current-carrying stability, ingress protection rating, mechanical strength, aging resistance and short-circuit withstand capacity. All test data meet standard requirements, making the product fully applicable to long-term high-current and uninterrupted DC power transmission operating conditions.

The complete set of qualifications can effectively verify the rational structural design, standardized production process and stable safe operation of the product to eliminate potential safety risks. All certificates and test reports can be delivered together with goods, supporting project submission, acceptance, bidding and customer filing. They fully satisfy the qualification review requirements of various large and medium-sized projects covering new energy, energy storage, computing power centers and industrial power distribution.
