6kV/10kV/20kV to 0.4kV Transformer Solution for Mining Industry Projects
Industry Pain Points
Mining sites feature harsh environments, heavy impact loads and continuous operation. Traditional distribution transformers face prominent industry pain points in mining scenarios:
1. Severe dust, moisture, chemical corrosion and long-term mechanical vibration lead to high transformer failure rate and short service life.
2. Mining equipment such as excavators and crushers produce frequent impact loads and harmonic interference, causing voltage fluctuation and poor power quality.
3. Long-time continuous operation and unbalanced load result in high no-load and load loss, bringing high power operation costs.
4. Mining areas have strict explosion-proof and safety requirements. Ordinary transformers have hidden explosion and fire risks, failing mine safety standards.
5. Remote mining sites lack intelligent monitoring, relying on manual inspection with high O&M costs and difficult fault emergency disposal.
