Global Certification Standards
Our 500 kva Compact Substation complies with global mainstream electrical safety and power equipment standards, with complete formal qualifications for international market access. The product strictly follows IEC 61332, IEC 60298 and IEC 62271 international standards and has obtained CE certification (LVD & EMC) for the European market. It passes ISO9001 quality management system certification and meets national GB7251, GB17467 and other power industry specifications. Every unit undergoes strict factory tests including power frequency withstand voltage, partial discharge, insulation detection, full-load operation and safety interlock test, fully meeting power safety operation requirements of various countries and regions.

Exported Countries & Market Coverage
With stable performance, cost-effective price and complete certification system, our 500kVA compact substation has been widely recognized and exported to global markets. It has long-term stable operation cases in Southeast Asia (Vietnam, Thailand, Malaysia, Indonesia), Middle East (UAE, Oman, Bahrain), Eastern Europe (Poland, Serbia, Albania), Africa (South Africa, Ghana, Ivory Coast, Uganda), Central Asia (Kazakhstan, Kyrgyzstan) and South America (Bolivia, Paraguay). The product can adapt to local climate conditions, 50/60Hz grid standards and power industry acceptance norms, and is widely used in overseas municipal power grid, industrial supporting and new energy power distribution projects.

Core Product Features
1. Mini Compact Structure & Space Saving: Optimized capacity matching and compact modular layout greatly reduce the overall equipment volume and floor area compared with traditional separate substations. The integral box-type structure requires no complicated room construction, adapting to urban intensive installation and limited-space construction scenarios.
2. Low Loss & Energy-Saving Operation: Equipped with high-quality low-loss 500kVA transformer core and high-purity copper winding. It features low no-load loss, low load loss and low operating temperature rise. The optimized electromagnetic design effectively reduces long-term power consumption, conforming to international energy-saving and low-carbon standards.
3. Strong All-Weather Environmental Adaptability: The outer box adopts high-strength galvanized steel plate and anti-corrosion electrostatic spraying process, with excellent waterproof, dustproof, anti-rust and anti-ultraviolet performance. Built-in automatic ventilation heat dissipation and constant moisture-proof device, ensuring stable operation in the environment of -40℃ to +55℃, suitable for high temperature, high humidity, sandstorm and other harsh outdoor working conditions.
4. Complete Safety Protection & High Reliability: Equipped with high-voltage short-circuit and overcurrent protection, low-voltage overload, leakage, overvoltage and undervoltage protection. It is equipped with reliable mechanical interlock, grounding protection and door-opening power-off safety device to prevent misoperation and equipment failure. The fully enclosed isolation structure effectively avoids external foreign matter invasion and electric shock risks.
5. High Compatibility & Flexible Customization: Supports 50Hz/60Hz dual-frequency global grid adaptation. Voltage grade, outgoing loop, protection configuration and protection level can be customized according to project needs, which can perfectly match the power distribution needs of municipal, industrial and new energy projects in different countries.

Product Advantages
1. High Cost Performance & Low Investment Threshold: As a mainstream small and medium-capacity power distribution equipment, it has lower overall equipment cost and installation cost compared with large-capacity compact substations. It balances performance and price, bringing higher economic benefits for small and medium-sized power engineering projects.
2. Fast Installation & Short Project Cycle: The whole machine is completely assembled, wired and debugged in the factory. On-site construction only needs integral hoisting and grounding connection, which can realize rapid power transmission, greatly saving construction and commissioning time.
3. Stable Performance & Low Failure Rate: Adopts mature and reliable structural design and brand-quality electrical components. The equipment operates stably for a long time with low heat generation and low noise. It is not easy to have aging failure in outdoor long-term continuous operation, with strong operational stability and anti-interference ability.
4. Simple Maintenance & Labor Saving: Modular partition design with independent maintenance areas for high-voltage, transformation and low-voltage parts. The structure is simple and clear, convenient for daily inspection, fault troubleshooting and parts replacement, effectively reducing later operation and maintenance costs.
5. Global Standard & Smooth Delivery: Equipped with full international certification, supporting global project bidding and local power grid acceptance. We provide multilingual technical documents, standardized packaging and global after-sales technical support to ensure smooth project delivery and stable after-sales operation.
