Mining Power Solutions - Your Heavy Industry Transformers & Reactors Manufacturer
LTECPower’s transformers, reactors, and grounding systems are specifically engineered for the mining, cement, and heavy industry to withstand the harshest environments and keep your plant running reliably.
Engineered Power Solutions for Harsh and High-Demand Heavy Industry
Crushers, conveyors, mills, and large-scale motors in heavy industries—such as mining operations, cement plants, steelworks, and open-pit mines are the workhorses, facing some of the most demanding electrical challenges found anywhere on Earth. They create severe electrical challenges: voltage fluctuations, harmonic distortion, and extremely high inrush currents. Nonlinear loads also create the risk of ground faults in underground mines, which can cause damage to the equipment, costly downtime, and even safety hazards.
At LTECPower, we understand these challenges because we have engineered solutions for them for decades. Our complete suite of custom-engineered power quality solutions designed specifically for harsh industrial environments, including MV dry-type transformers that handle high inrush currents and deliver stable voltage regulation, neutral grounding reactors that limit the ground fault currents and enhance the personnel safety, air-core reactors that provide linear, saturation‑free performance for current limiting and reactive power compensation, and the harmonic filtering components that suppress harmonics generated by VFDs to prevent your equipment overheating and extending system life.
Every LTECPower component features rugged mechanical construction and exceptional thermal resistance, making it well-suited for extreme operating conditions. Our solutions effectively minimize your equipment downtime, extend equipment life, and ensure the safe and stable operation of your machinery in mining and heavy industrial applications. Furthermore, it significantly reduces the overall Total Cost of Ownership (TCO) for your equipment.
Seismic-Reinforced and Vibration-Resistant Engineering for Rock Crushers
Rock crushers and grinding mills do not just crush materials, they also generate intense, high‑frequency vibrations that would tear apart ordinary electrical equipment over time. LTECPower delivers the MV transformers and air-core reactors, built with reinforced structural supports and specialized vibration-damping mounts, helping to eliminate the mechanical stress on windings and cores before it can cause damage. So your equipment can achieve a service life of over 25 years, even under the most demanding field conditions.
Dust-Proof and Corrosion-Resistant Enclosures for Corrosive Environments
In a cement plant and a coastal mine, the fine dust and salt spray eat away at your transformer’s insulation and unprotected metal. They both bring your equipment flashover, short circuits, and costly downtime. LTECPower’s custom‑engineered 316L stainless steel or epoxy‑coated enclosures with IP54/IP55 protection give you reinforced construction, corrosion‑resistant materials with exceptional thermal endurance. So, our transformers and reactors deliver you a long‑term, reliable operation — even in the most demanding mining and heavy industrial applications.
Advanced Power Quality Solutions for Stable Operation of Heavy Industrial Equipment
Mining systems run on VFD motors and massive electrical loads, but the power often brings harmonic interference and voltage instability. If it is left unchecked, the trip drives, overheated motors may bring your production to a halt. However, we solve that at the source. Our reactors, filters, and grounding solutions can work together to help you suppress harmonics, limit fault currents, and stabilize voltage. So you can get a safe power system, always efficient and online.
Core Power Quality Products for Heavy Industry
Constructed to endure severe electrical stresses, LTECPower’s heavy-duty power transformers, reactors, and wave filters deliver you stable power distribution, reliable fault isolation, and motor protection under the most demanding heavy industrial and mining operations.
Medium Voltage Dry-Type Power Transformers
Built for the toughest industrial environments, our MV dry‑type transformers handle the challenges of mining and heavy industry day after day, year after year.
Neutral Grounding Reactors
By providing a controlled fault current path, our NGRs limit the energy that flows through your system with enhanced stability for your equipment.
Air-Core Reactors
Air‑core reactors never saturate, so they deliver you superior linearity and reliable performance — even under extreme fault conditions.
DC Reactors
Applied in Variable Frequency Drive (VFD) systems, our DC reactors smooth DC and reduce harmonic distortion, protecting your mining equipment from the inside out.
Sine Wave Filters
Our sine wave filters protect your motors from voltage spikes and improve waveform quality with extended motor life, even in applications with long cable runs and demanding power requirements.

How do you handle transformer derating for high-altitude mining sites?
At high altitudes (typically above 1,000m), thin air reduces heat dissipation efficiency. So by increasing insulation clearances and optimizing cooling surface design, our transformers ensure you full nameplate capacity (kVA) without overheating.
What is the advantage of an Air-Core Reactor in a mining substation?
During high-current faults, iron-core reactors can saturate. However, air-core reactors never. Our air-core reactors deliver perfect linearity even under extreme current surges, making them ideal for your mining substations where short‑circuit protection is critical.
Can your Neutral Grounding Reactors (NGR) replace brands like Post Glover?
Absolutely. Our NGRs are custom‑engineered to match the physical dimensions and electrical specifications of major brands, and with the same performance.
How do you protect transformers and reactors from coal dust or cement dust?
There are two options for you. The ventilated enclosures with IP54 protection or a totally enclosed, non‑ventilated (TENV) design. Both of them can prevent dust accumulation that may cause surface discharge (tracking) and electrical arcing. You can choose the conditions on your site.
Are your transformers suitable for mobile substations in open-pit mining?
Absolutely. Our transformers are compact, robust, and built to withstand frequent relocation across rugged terrain. Our resin casting or VPI processes add extra durability, making our transformers ideal for your mobile substations in open‑pit mining.
