Engineering Case Study: Electrical & Automation

Rugged Electrical Engineering for Mining & Heavy Industries

Engineered to withstand extreme conductive dust, severe mechanical vibration, and heavy inductive motor starting loads across SAG mills, crushers, and overland conveyor networks.

Harsh Industrial Challenges & AHT Engineering Solutions

Mineral extraction plants cannot afford unpredicted halts. A single conveyor trip costs thousands of dollars per hour.

01

MV Switchgear & Ball Mill Starters

Challenge: Massive starting torque spikes, power factor drops, and fine conductive mineral dust ingress.

Solution: 33kV Metal-Clad switchgear with IP54 pressurized cubicles, integrated with Liquid Resistance Starters (LRS) or MV Soft Starters to damp grid voltage sags.

Standard: IEC 62271-200 / EPIL
Dust-Sealed IP54

02

Harmonic-Mitigated VFD & MCC

Challenge: High ambient heat inside E-Houses and severe harmonic distortion damaging sensitive drives.

Solution: Form 4b modular MCCs equipped with Active Harmonic Filters (IEEE 519 compliance), forced heat-pipe cooling channels, and shock-mounted frames.

Standard: IEC 61439-2 / IEEE 519
THDi < 5%

03

Overland Conveyor & Mill Automation

Challenge: Long-distance signal loss, belt rip risks, and sudden mechanical jams on primary crushers.

Solution: Fiber-optic redundant ring SCADA (IEC 62439 PRP/HSR) linked with distributed I/O, automated belt sway/pull-cord trip matrix, and torque-limiting PLC routines.

Fieldbus: Profinet / FO Ring

Mining & Heavy Industry FAQs

Engineering protection against dust, heat, and grid surges.

How do AHT panels prevent fine mineral dust ingress?

We implement IP54 to IP65 rated enclosures featuring seamless continuous polyurethane foam gaskets, labyrinth air filtration vents, and internal over-pressure options to keep conductive mineral and cement dust out of electrical contacts.

Can you design panels for remote containerized E-Houses?

Yes. We provide complete skid-mounted and containerized modular E-House solutions fully equipped with MV switchgear, LV MCC, UPS, HVAC, and fire suppression systems, completely pre-wired and factory-tested prior to export.

What documents are supplied with heavy industrial panels?

Each unit is shipped with an exhaustive Technical Dossier: full EPLAN P8 multi-line schematics, thermal dissipation calculations, dynamic short-circuit reports, motor protection relay setting tables, FAT check sheets, and warranty certificates.
