Blue Arrow's power distribution equipment has not only entered industrial parks in Germany but also taken root in domestic data centers. We have delivered two equally excellent "power answer sheets" using two completely different installation solutions—and behind this lies the core difference between domestic and international power distribution installations.

I. Installation in Germany: Environmental Compliance as the Principle, Zero Tolerance for Details

1. The "Environmental Protection Question" in Friedberg

In the industrial area of Friedberg, Germany, the customer needed a medium-voltage substation that must comply with EU environmental standards, and the installation process must not damage the ecological environment around the industrial park.

This is precisely the first core difference in German installations—environmental compliance has the highest priority. Before departing, our team replaced all high-voltage switchgear with SF₆-free, environmentally friendly gas-insulated models. Additionally, Germany has extremely detailed requirements for "reserved capacity expansion"—the customer clearly stated that 200kVA of additional photovoltaic installed capacity might be added in the next 5 years. Our installation team not only reserved corresponding interfaces but also conducted on-site simulated capacity expansion tests to ensure no modifications to the main structure would be needed for subsequent connection. This "paving the way in advance for the future" installation mindset is particularly evident in German projects.

2. The "Standardization Trap" in Wolfenbüttel

A sewage treatment plant in Wolfenbüttel, Germany, needed to build a 1000kVA photovoltaic energy storage grid-connected system, with the core requirement of "high-efficiency grid connection of integrated PV-storage". However, before installation, we encountered a problem: the local electrical installation standards (VDE standards) differ greatly from those in China, with dozens of detailed rules just for cable wiring process requirements.

This is the second difference in German installations—the standard system is strict and detailed. The testing of equipment grounding resistance must not only comply with IEC standards but also pass on-site certification by local third-party institutions. Our installation team studied the VDE standards half a month in advance, turned each operation step into a standardized manual, and implemented it on-site against the manual. Finally, the installation and commissioning were completed, and every detail passed the acceptance inspection of the German power grid.

More notably, installation scenarios for German projects are mostly combined with new energy and emphasize "minimum intervention"—the installation area of the sewage treatment plant was adjacent to the sedimentation tank. Our team adopted modular hoisting, with all equipment pre-installed in the factory and only assembled on-site, avoiding the impact of construction dust and noise on the sewage treatment process.

II. Domestic Installation: Efficiency Adaptation as the Priority, Closed-Loop Service

3. The "Customization Challenge" at Huailai Cloud Data Center

The computer room building project of Huailai Cloud Data Center urgently needed a supporting low-voltage power distribution system, with clear core demands: complete the delivery and installation of 106 low-voltage switchgear (including 6 additional units), adapt to the "high-density, high-reliability" operation requirements of the data center, and at the same time meet rigid technical specifications such as authorized production of Schneider BLOKSET cabinet type and copper bar purity ≥99.95%.

This is exactly the core difference in domestic installations—efficiency first, adapting to complex scenarios. The data center computer room has a compact space and requires "zero interruption" for power supply stability. Our team entered the site in advance for surveying and mapping, and carried out customized design for the 106 switchgear based on the computer room layout: cabinet dimensions were precise to the millimeter to avoid conflicts with air conditioning and fire protection systems; high-conductivity electrolytic copper was used for the busbars inside the cabinets, with insulating sleeves added to ensure safety; all components were selected from Schneider MT and NSX series to ensure perfect adaptation to the authorized cabinet type.

Another notable feature of domestic installations is the full-cycle closed-loop service. During the project initiation phase, we cooperated with the customer to complete in-depth design and technical review, and provided a full set of construction drawings and component qualification certificates; during the installation process, we synchronized the construction progress in real time and accepted random inspections by third parties on indicators such as copper bar purity and insulation resistance; after delivery, we conducted equipment operation and maintenance training, and also promised 1-2 on-site technical support visits per year during the warranty period. In addition, we issued a warranty letter accounting for 15% of the total contract price in accordance with the contract requirements, providing solid protection for the 2-year warranty period of the equipment.

III. Core of Cross-Border Differences: Adapting to Local Conditions with Precision

• Environmental Protection and Compliance: Overseas (Germany) takes environmental regulations as hard constraints, with requirements such as SF₆-free and recyclable packaging implemented throughout the process; domestic installations focus more on the standardization of equipment operation, with compliance requirements centered on safety standards (e.g., 3C certification, seismic testing) and technical specifications (e.g., IEC, GB standards).
• Standards and Details: Overseas standards (e.g., VDE) are detailed down to operation processes, with strict acceptance procedures and high participation of third parties; domestic standards focus more on systematic compliance, balancing installation efficiency and detail adaptability, and need to meet the customized technical requirements of the project.
• Demands and Scenarios: Overseas projects are mostly combined with new energy scenarios, emphasizing long-term capacity expansion and minimum ecological intervention; domestic core projects (e.g., data centers) focus more on high density, high reliability, and rapid delivery, and need to align with the overall construction schedule of the project.
• Service Model: Overseas markets value pre-installation standard adaptation and environmental certification more; domestic markets rely on full-cycle closed-loop services, following up the entire process from design, production, and installation to operation and maintenance, and providing customized solutions and warranty guarantees.

The confidence of Blue Arrow Electric Control over 30 years stems from this "adapting to local conditions" capability—in Germany, we meet international demands with environmental protection technology and strict standards; in China, we satisfy infrastructure speed with efficient delivery and full-cycle services. Whether it is an overseas industrial park thousands of miles away or a core urban data center, Blue Arrow's power distribution equipment is guarding the reliable transmission of every kilowatt-hour of electricity in the most suitable way.
