Pioneering high-reliability power infrastructure and tailored OEM/ODM BESS integration platforms since 2011.
Established in 2011 and located in Dongguan, Guangdong Province, China, Zago Electric operates a modern manufacturing facility covering more than 12,000 square meters. By combining state-of-the-art sheet metal laser cutting, CNC punching, automated busbar processing, and digital assembly lines, we guarantee millimeter-level precision across every enclosure.
Dongguan Zago Electric Co., Ltd. provides full-lifecycle OEM and ODM services to electrical contractors, engineering companies, system integrators, distributors, and project developers worldwide. Our portfolio ranges from specialized low-voltage/medium-voltage distribution boards to fully integrated containerized battery energy storage enclosures.
We place strong emphasis on operational safety, long-term performance reliability, and strict compliance with international benchmarks (IEC 62271, UL 9540A, IEEE standards). With active projects across Europe, North America, Southeast Asia, the Middle East, Africa, and Latin America, our systems are field-tested under harsh ambient conditions.
Through continuous investment in technology, engineering expertise, and high-precision manufacturing capabilities, Zago Electric remains committed to supplying safe, efficient, scalable, and intelligent switchgear systems tailored to support modern grid decarbonization and commercial-scale energy storage requirements.
Analyzing the shift from traditional power protection to dynamic grid stabilization, microgrids, and intelligent OEM BESS architectures.
As intermittent renewable sources (solar PV and wind) penetrate high-voltage distribution networks globally, utilities and industrial operators encounter severe voltage fluctuations. Custom BESS and medium-voltage gas-insulated switchgear (GIS) are increasingly required to provide frequency regulation, active power ramping, and zero-delay peak shaving capabilities.
Modern hyper-scale and AI data centers require uninterruptible, ultra-clean power with sub-millisecond automated transfer switches. Engineering procurement teams demand metal-clad switchgear equipped with IoT sensor arrays for continuous condition monitoring, preventing costly power outages and thermal events.
Global environmental mandates are pushing switchgear manufacturers to migrate away from high-GWP gases like Sulfur Hexafluoride (SF6). OEM procurement guidelines increasingly prioritize vacuum circuit breaker (VCB) technology, dry-air insulated compact RMUs, and recyclable structural components for sustainable lifecycle footprints.

Modular, high-density, and containerized power engineering engineered for demanding OEM deployments.
We build fully turn-key containerized energy storage units integrating lithium-iron-phosphate (LFP) battery racks, Liquid-to-Air heat exchangers, PCS (Power Conversion Systems), and custom medium-voltage step-up transformers into a single structurally reinforced chassis.
Engineered for factory complexes and remote facilities, our C&I switchgear solutions feature multi-source paralleling control panels. They effortlessly synchronize generator sets, roof solar arrays, and grid connections while prioritizing critical plant loads dynamically.
Featuring operating voltages ranging from 12kV up to 40.5kV, our GTP5.1-12 type GIS and metal-enclosed withdrawable panels provide exceptional dielectric strength within compact footprints, ideal for space-constrained urban substations.
Ensuring absolute compliance with strict utility regulations, structural safety, and grid interoperability worldwide.
Every low-voltage and medium-voltage switchgear assembly undergoes rigorous routine inspections, including power frequency withstand voltage tests, primary current injection tests, contact resistance measurements, and mechanical operation verification.
We customize physical busbar arrangements, incoming cable entry positions (top/bottom), color schemes (RAL variants), phase configurations, and local utility metering modules to match specific regional installation codes.
Our outdoor-grade IP66 and skid-mounted mobile distribution enclosures are treated with heavy-duty anti-corrosion marine powder coatings, engineered to withstand high humidity, coastal salt mist, desert dust storms, and extreme temperatures (-40°C to +55°C).
From pre-project engineering design validation (CAD/3D modeling) to Factory Acceptance Testing (FAT) and Remote Technical Supervision during Site Acceptance Testing (SAT), Dongguan Zago Electric guarantees continuous customer support.
Driving technological leaps in solid-state integration, eco-insulating gases, and AI-driven predictive switchgear edge computing.
Accelerating the deployment of dry air and fluoronitrile gas mixture insulation systems across our 12kV and 24kV medium-voltage product lines, eliminating direct greenhouse gas emissions in high-voltage substations while retaining compact physical footprints.
Embedding low-latency AI edge microprocessors inside intelligent withdrawable switchgear panels. Algorithms analyze real-time acoustic signatures, thermal hot-spot trends, and partial discharge pulses to predict contact degradation 90 days before potential failure.
Architecting next-generation 5MWh+ single-container BESS solutions integrated directly with solid-state transformer interfaces and ultra-fast liquid cooling circuits for optimized round-trip efficiency (RTE > 92%).
