Partnership with Rio Tinto: Supplying First Class C Insulated VPI Dry-Type Transformers Made in China
For world-leading iron ore producers like Rio Tinto, the stability of the power supply is the backbone of production. The mining industry presents a unique set of engineering challenges: equipment must endure heavy dust accumulation, frequent load fluctuations from heavy machinery, and strict safety protocols regarding fire hazards in confined or remote environments.
Rio Tinto needed a partner capable of delivering transformers that offered high overload capacity and impeccable safety records, all while adhering to stringent international compliance standards. CEEG provided the solution.
The Challenge: Dust, Heat, and Heavy Loads
Mining operations cannot afford downtime. The electrical infrastructure must solve three critical industry problems:
Heavy Duty Cycles: Mining machinery creates massive power spikes. Transformers must handle rapid load changes and high thermal stress without degrading.
Fire Safety & Ventilation: In processing plants and ventilated environments, equipment must be self-extinguishing and risk-free (Class F1 standard).
Dust Contamination: Iron ore production generates significant dust, requiring equipment that is easy to maintain and resistant to clogging or tracking.
The Solution: CEEG's VPI Technology & Global Compliance
CEEG addressed these specific operational pain points by delivering 52 sets of class C insulated VPI transformers to Rio Tinto in 2012:
Handling Thermal Stress: By utilizing DuPont Nomex® insulation technology, CEEG transformers can withstand temperatures up to 220°C. This high thermal reserve allows the units to easily handle the overload shocks typical of mining operations without aging prematurely.
Certified Compliance: CEEG proved its ability to meet global regulatory requirements. The units are the fifirst CSA-certified Class C insulated ventilated transformers produced in China, also passed KEMA E2, C2, and F1 tests, certifying their reliability against environmental stress and fire risks.
Operational Efficiency: We helped Rio Tinto reduce their carbon footprint and operating costs by achieving a remarkable 99.26% energy efficiency.
The Result: A Trusted Global Resource
The deployment was a success, earning CEEG the "Most Innovative Supplier Award" in emerging markets and securing our status as a Rio Tinto Certified Supplier.
In 2018, the partnership expanded when Rio Tinto dispatched a 10-member global procurement team to CEEG’s manufacturing base. The team audited our manufacturing processes and technical expertise to ensure our consistency in continuous, long-term cooperation, as well as to assess our potential to supply other Rio Tinto plants. This successful visit confirmed our manufacturing capabilities and laid a solid ground for our cooperation relationship till today.
