Aper\u00e7u du projet<\/h3>\n\n\n\n

This project delivered a custom transformer package for an active mining operation in Australia, where strict environmental protection rules and rugged site operating conditions set high technical barriers for power distribution equipment.<\/p>\n\n\n\n

The client required five distribution transformers plus one earthing transformer<\/strong>, with the main unit rated at OPMI 2500kVA, 11kV \/ 415V<\/strong>. Instead of conventional mineral oil, the client selected FR3 high-fire-point vegetable dielectric fluid<\/strong> to meet Australia\u2019s stringent environmental & fire safety requirements.<\/p>\n\n\n\n

Core Project Requirements<\/h3>\n\n\n\n

Dielectric Fluid<\/strong>: FR3 high flash-point vegetable oil. Biodegradable, low toxicity, greatly reduces fire hazard and soil contamination risk \u2014 critical for Australian mine environmental compliance. <\/p>\n\n\n\n

Transformer Configuration<\/strong>: 5 \u00d7 distribution transformers + 1 \u00d7 earthing transformer. Main transformer: OPMI 2500kVA, 11kV \/ 415V, mining & industrial duty. <\/p>\n\n\n\n

Mechanical Design<\/strong>: Reinforced cooling system as required by Australian standards, to handle high ambient temperature and continuous heavy-load mining operation. <\/p>\n\n\n\n

Containment & Safety<\/strong>: Integral oil containment sump (oil pit \/ bund) to contain fluid leakage, preventing soil and groundwater pollution, mandatory for Australian mine sites. <\/p>\n\n\n\n

Earthing transformer<\/strong>: Dedicated earthing transformer included for proper neutral earthing, stabilising 11kV network fault conditions on the mine power system.<\/p>\n\n\n\n

Our Customised Solution<\/h3>\n\n\n\n

We engineered the full transformer package tailored to Australian mining specifications:<\/p>\n\n\n\n
