Established in 2025, the company is a specialized supplier in electrical equipment manufacturing, with a core team of 72 engineers covering mechanical design, software development, and installation. The systems are tailored for global transformer manufacturers, addressing key industry pain points including low testing efficiency, manual data inaccuracies, and incomplete compliance verification. Strictly adhering to IEC 60076, ISO 9001, and ISO 14001 standards, the systems feature a breakthrough one-time wiring and fully automated testing design. To date, the technology has been deployed in 5+ countries including the US, Mexico, and Indonesia, serving over 200 transformer factories, and has earned ISO 9001, ISO 14001, and ISO 45001 certifications for reliable performance.

Technical Definition & Classification

The Fully Automatic Distribution Transformer Testing System is an integrated precision testing solution for power transformers, based on automated control and high-precision measurement technologies. It enables one-time wiring to complete all factory routine tests—including insulation resistance, DC resistance, ratio and group, no-load, load, induced voltage withstand, and AC voltage withstand—automatically, realizing unmanned, intelligent testing with traceable data. As a critical component in electrical equipment quality control, it supports efficient, standardized production for transformer manufacturers.

To meet diverse global demands, the system includes three core series with customizable options: NKE-DTTS-AUTO/500, designed for 0.12–1.5kV, 500kVA transformers with 0.05 accuracy class; NKE-DTTS-AUTO/5000, suitable for 38.5kV, 5000kVA dry or oil-immersed transformers with 7×24 technical support; and NKE-DTTS-AUTO/10000, featuring a 20-foot containerized structure for overseas project delivery, supporting 10000kVA, 38.5kV transformers. The product design prioritizes high precision, operational safety, compliance, and global adaptability to withstand harsh industrial conditions.

Core Technical Advantages

1. One-Time Wiring & Fully Automated Testing: The system integrates 7 routine test items into a single workflow, eliminating repeated wiring and manual operation. This reduces testing time by 80% compared to traditional manual methods, cuts labor costs by 60%, and eliminates human-induced data errors, ensuring consistent, standardized testing for mass production.

2. High Precision & Compliance: With a 0.05 accuracy class, the system meets IEC 60076 international standards, providing traceable, reliable test data that supports compliance with global market access requirements. All test results are automatically generated into standardized reports, simplifying quality documentation and audit processes.

3. Global Deployment Capability: The containerized NKE-DTTS-AUTO/10000 model is optimized for sea freight, enabling on-site testing for overseas projects. The company holds full import-export qualifications, providing localized technical support and after-sales service in key markets including the US and Southeast Asia.

International Standards & Compliance

All systems are developed, produced, and tested in strict accordance with global standards, including IEC 60076 for transformer testing, ISO 9001:2015 (quality management), ISO 14001:2015 (environmental management), and ISO 45001:2018 (occupational health and safety). The company also holds national high-tech enterprise certification, provincial specialized and sophisticated enterprise status, and CNAS-accredited testing capabilities, ensuring full compliance with global market regulations. Complete import-export qualifications support seamless cross-border delivery and customs clearance.

Application Scenarios

The system serves four core global user groups: transformer manufacturers for factory routine testing and mass production quality control; third-party testing institutions for product certification and compliance verification; power grid companies for grid access acceptance testing; and overseas project contractors for on-site mobile testing using containerized models. In real-world applications, it has helped clients increase production efficiency by 40% and reduce product defect rates to below 0.5%.
