The product complies with IEC 61332 and IEC 60298 international power equipment standards, and has passed CE certification for EU market access, covering electrical safety, electromagnetic compatibility and low-voltage safety specifications. Meanwhile, it conforms to ISO9001 quality management system certification, national GB7251 and GB17467 power industry standards. All units undergo strict factory tests including insulation resistance test, partial discharge test, voltage withstand test and overload operation test, ensuring full compliance with power safety operation standards in various countries and regions.

Exported Countries & Market Coverage
Benefiting from standardized design, reliable performance and global certification system, our 1250 kva Compact Substation has been successfully exported to more than 40 countries and regions around the world, with a large number of stable on-site operation cases. The product is widely applied and recognized in Southeast Asia (Thailand, Cambodia, Myanmar, Singapore), Middle East (UAE, Saudi Arabia, Qatar, Kuwait), Europe (Poland, Romania, Bulgaria), Africa (Kenya, Tanzania, Cameroon, Zambia), Oceania (Australia, New Zealand) and Latin America (Mexico, Colombia, Ecuador). It can adapt to local power grid parameters, climatic environments and electrical industry norms, and has become the preferred compact power distribution equipment for many overseas engineering contractors and power enterprises.

Core Product Features
1. Ultra-Compact Integrated Design & Small Occupied Space: Adopts highly integrated modular layout of high-voltage unit, 1250kva transformation unit and low-voltage distribution unit. Compared with traditional separate power distribution equipment, the overall volume and floor space are reduced by more than 60%. The whole machine has a standardized box-type structure, which does not require large-scale civil construction, and is suitable for space-limited installation scenarios such as urban dense areas and narrow construction sites.
2. Excellent Power Conversion & Energy-Saving Performance: Equipped with high-performance 1250kva low-loss transformer core and high-purity copper winding, with extremely low no-load loss and load loss. The product supports long-term full-load stable operation, with low heat generation and low noise during operation. The optimized electromagnetic structure effectively reduces power consumption loss, meeting the energy-saving and emission-reduction requirements of global power industry and long-term low-consumption operation needs.
3. All-Weather Environmental Adaptability: The box body adopts high-strength galvanized steel plate and anti-corrosion spray treatment, with waterproof, dustproof, anti-rust and anti-ultraviolet functions. It is equipped with automatic ventilation and heat dissipation system and moisture-proof dehumidification device inside, which can stably adapt to harsh environments such as high temperature, high humidity, strong wind, rain and sand dust. It can operate normally in the temperature range of -40℃ to +55℃, suitable for tropical, temperate and subtropical regional environments.
4. Complete Multi-Dimensional Safety Protection: Built-in perfect protection mechanisms including high-voltage overcurrent and short-circuit protection, low-voltage overload, leakage and overvoltage protection. It is equipped with mechanical interlock device, lightning protection and grounding device, and door opening power-off safety device to prevent misoperation and equipment failure risks. The fully enclosed isolation structure effectively avoids electric shock hazards and external object invasion, ensuring safe operation of equipment and power grid.
5. Flexible Parameter Matching & Strong Compatibility: Support customized high and low voltage specifications, compatible with 50Hz/60Hz global mainstream power grid frequency standards. The output voltage and distribution loop can be adjusted according to customer engineering needs, which can perfectly match the power supply needs of industrial equipment, civil buildings and engineering construction equipment in different countries.

Product Advantages
1. Standardized Certification & Wide Market Adaptability: Equipped with full international and domestic authoritative certifications, which can quickly pass local power department inspection and project acceptance in various overseas regions. The standardized design conforms to global mainstream power industry specifications, with zero market access threshold, suitable for global engineering bidding and project supporting.
2. Time & Cost Saving & High Cost Performance: The whole machine is fully assembled, wired and debugged in the factory, realizing on-site hoisting and immediate power supply, greatly shortening on-site construction and commissioning cycle. The integrated design saves a lot of civil construction, equipment purchase and later transformation costs, and the low-loss operation characteristic effectively reduces long-term power operation costs for customers.
3. Stable Operation & Long Service Life: Adopts high-quality raw materials and precision manufacturing process, with stable electrical performance and strong structural durability. The anti-corrosion, moisture-proof and dust-proof design avoids equipment aging and failure caused by environmental factors. Under normal operation and maintenance, the service life can reach more than 25 years, with low failure rate and stable long-term power supply capacity.
4. Simple Maintenance & High Operation Efficiency: Modular partition design inside the equipment, with independent maintenance channels for each functional unit, convenient for daily inspection, fault troubleshooting and component replacement. The intelligent monitoring interface can display real-time operating data such as voltage, current and temperature, helping users quickly grasp the equipment operation status and improve overall power supply management efficiency.
5. Customizable & Professional Global Service: Support personalized customization of box appearance, protection level, internal configuration and electrical parameters according to customer site conditions and project requirements. We provide professional English version technical manuals, installation guidelines and global after-sales support, including remote technical guidance, on-site installation debugging and regular equipment maintenance services for overseas customers.
