Specialized Medium Voltage power solutions engineered for the extreme requirements of heavy-duty mining operations in high-altitude environments. Our design focuses on low-temperature resilience, anti-attenuation insulation for low atmospheric pressure, and superior adaptation to high-impact loads.
Core Value Propositions
Adaptation to Heavy Impulse Loads
Mining equipment such as crushers and hoists generate intense, intermittent impulse loads. Our transformers utilize reinforced anti-impulse winding designs to prevent coil deformation, ensuring grid stability and avoiding frequent circuit trips or equipment failure.Extreme High-Altitude & Low-Temp Resilience
Specifically designed for low-pressure environments above 3,000 meters. We utilize reinforced insulation materials and specialized low-temperature dielectric fluids to maintain insulation strength and ensure stable cold-starts in environments reaching -25°C.OPEX Reduction & Efficiency Optimization
Mining operations are energy-intensive. Our transformers feature ultra-low loss designs (No-load loss ≤ 0.8% / Load loss ≤ 1.2%), directly assisting mining companies in controlling integrated operational costs and improving energy efficiency.

Engineered for Extreme Mining Performance
We integrate specialized technical features to extend service life under low pressure and high-impact conditions:
● Multi-layer interference shielding between HV and LV windings suppresses harmonic disturbances generated by mining VFDs and heavy machinery, preventing abnormal coupling with grounded parts.
● Utilizing reinforced copper bars and a specialized layered fastening process, our windings can withstand current impulses up to 3 times the rated value, perfectly matching the "high power, intermittent operation" cycles of mining equipment.
● Advanced low-pressure resistant insulation materials paired with Vacuum Pressure Impregnation (VPI) eliminate partial discharge and insulation breakdown in thin-air environments up to 3000m.

FAQ: Deployment & Operation
Q: How much construction time can the "Rapid Deployment" feature save for temporary mining power?
A: Our prefabricated mining substations reduce the construction cycle by approximately 60%. Traditional on-site assembly at high altitudes (including logistics, welding, and wiring) typically requires 15–20 days. Our integrated units are factory-tested and ready for use; once on-site, they only require foundation fixing and cable connection, allowing deployment to be completed within 2 to 3 days.
Q: Can the YB-MT series accommodate specific switchgear brands used in my current mine?
A: Yes. We offer fully customizable configurations. You can specify switchgear brands to ensure the unit seamlessly matches your existing power distribution system and maintenance protocols.
