Power Supply Project for Iron Ore Mine in Australia

An iron ore mining customer in Australia adopted multiple models of PAUWAY generator sets including PWS2250CL+, PWS2500CL+, PWM1250C and PWM1100MVS. The product lineup covers a power range from 500KW to 1800KW with output voltage ranging from 400V to 10.5KV, forming a complete distributed power supply system for open-pit mining, ore processing and auxiliary supporting facilities.

Project Background & Tender Award

Large open-pit iron ore mines feature wide operation areas, scattered working faces and diverse load types. Low-voltage units serve on-site mobile machinery and daily auxiliary power consumption, while high-voltage generator sets realize long-distance power transmission for concentrators and fixed large-scale production equipment. Strict standards on equipment durability, dust resistance and continuous operation are required to adapt to harsh open-air mining conditions.

Core Technology & Equipment Configuration

Generating Units

The project deploys mixed models of PWS series large power units and PWM series standard units: PWS2250CL+, PWS2500CL+, PWM1250C, PWM1100MVS. The power spectrum spans 500KW to 1800KW, supporting both 400V low-voltage direct power supply and 10.5KV high-voltage centralized power supply, which can be flexibly matched to long-distance power distribution and nearby equipment power supply demands of the mining area.

Project Positioning

Integrated low & high voltage distributed power station for large iron ore mine, supplying power to excavation equipment, ore crushing & screening workshops, dewatering systems, drainage pumps and site living guarantee systems in phases and zones.

Equipment Features

• Full power coverage 500KW–1800KW, voltage system of 400V low voltage or 10.5KV high voltage
• Multiple unit models support parallel connection and group control to expand power capacity on demand
• Reinforced dustproof, shockproof and anti-corrosion structure adapting to open-pit mining dusty and bumpy environment
• Compliant with Australian local electrical safety certification and mine environmental access standards

Project Significance & Challenges

Project Value

The mixed high-low voltage power solution realizes zoned power supply for the whole mining area, effectively reducing line loss during long-distance power transmission, ensuring continuous operation of core mineral processing production lines, and demonstrating PAUWAY’s comprehensive customized supporting capability for large overseas mineral projects.

Execution Challenges

Completed high-voltage system insulation test and parameter setting, passed Australian mining industry safety and electrical certification, realized multi-machine group parallel control debugging, and strengthened unit protection to resist strong wind, sand and high temperature open-pit working conditions.
