Explore our top-tier Wolong & ATB brand high voltage three-phase AC induction motors engineered specifically to handle the challenging power grid dynamics and tropical climatic conditions in Nigeria.
Nigeria represents one of the fastest-growing industrial landscapes in Sub-Saharan Africa. The rapid expansion of sectors like the Dangote Refinery in Lagos, major cement plants (BUA, Lafarge, Dangote Cement) in Kogi, Ogun, and Cross River states, alongside extensive municipal water board updates and mining operations, demands highly robust heavy-duty equipment. However, Nigeria's power grid is historically characterized by frequent voltage dips, power factor challenges, and a high-temperature, highly humid environment. This places an extraordinary mechanical and thermal load on heavy-duty electric motors.
In industrial sectors that depend heavily on continuous operations, a minor fault in an AC High Voltage motor can lead to plant-wide shutdowns costing millions of Nairas. Standard electric motors fail prematurely under local conditions due to insulation breakdown caused by harmonic feedback or thermal overloading. Therefore, heavy industries in Nigeria require robust AC High Voltage motors (ranging from 3kV to 11kV) designed with reinforced Vacuum Pressure Impregnation (VPI) insulation, highly efficient cooling systems, and the ability to withstand wide variations in power frequency. As a leading exporter of AC HV motors, we specialize in delivering tailored configurations that balance global manufacturing standards with regional operational realities.
Our high voltage motor range is directly customized to match the unique mechanical demands of Nigeria's core economic sectors.
Whether for oil transport pumps in the Niger Delta or gas compressor stations, our ATEX and IECEx explosion-proof motors (such as the Wolong TAW or YFBKK series) guarantee safe operation in explosive gas atmospheres (Zone 1 and Zone 2).
Highly abrasive dust atmospheres in cement plants require motors with extreme ingress protection. Our YR series wound rotor induction motors are custom-built to deliver high starting torque under heavy loads, driving large ball mills and crushers smoothly.
For large-scale water treatment plants in metropolitan Lagos or Abuja, our YKS water-cooled and YKK air-cooled AC motors power critical high-capacity pumps, ensuring a continuous clean water supply with optimized energy consumption.
Shaanxi Nanfang Motor Technology Co., Ltd. is the authorized distributor of Wolong. Wolong Electric Drive Group Co., Ltd. was founded in 1984 and successfully listed in 2002 (code SH600580). After more than 30 years of development, Wolong has established 3 manufacturing bases, 39 factories, and 3 R&D centers globally. Wolong is committed to a global brand strategy, leading in R&D, technology, manufacturing, and sales in the global market.
Through strategic acquisitions, Wolong has integrated internationally renowned century-old brands, including ATB, Brook Crompton, Morley, Laurence Scott, Schorch, and OLI. Furthermore, the acquisition of China's largest explosion-proof motor scientific research and production base, Nanyang Explosion Protection Group (CNE), alongside the acquisition of General Electric (GE) Industrial Motors division, has consolidated our ability to deliver unparalleled technical solutions globally.
Why Nigerian industrial buyers choose our integrated supply chain and engineering services over traditional European alternatives.
We do not offer a one-size-fits-all product. By utilizing digital multi-physics simulation platforms, we analyze the thermal, electrical, and structural behavior of our motors under tropical conditions. This design process ensures that each high voltage motor exported to Nigeria has high structural redundancy, excellent heat dissipation, and optimized starting characteristics that do not strain localized generators or mini-grids.
Through our vast Chinese manufacturing base, we combine the cost advantages of localized supply chains with European engineering standards (inherited via the acquisition of ATB and Schorch). This configuration allows us to offer heavy industrial motors with faster lead times, robust transit logistics to Lagos or Port Harcourt, and more cost-effective pricing than Western manufacturers without compromising on certification or performance.
Inside our advanced high voltage motors: Built for durability, efficiency, and low maintenance.
The rotor features a squirrel cage design, utilizing cast aluminum rotors produced via centrifugal aluminum casting or die-casting techniques. This merges the rotor bars and end rings into a single-piece construction for outstanding mechanical integrity and starting torque properties. For larger capacity configurations, copper bar rotors with high-specification end-ring welding and safety protective rings are employed to ensure reliability in high-speed applications.
Our stator coils are insulated with high mica-content tapes reinforced with glass cloth and polyester film. After assembly, the stator goes through our specialized Vacuum Pressure Impregnation (VPI) process. This creates a moisture-resistant, mechanically rigid winding configuration with high electrical insulation properties and thermal stability, crucial for humid locations like Lagos and Port Harcourt.
The motor frames are engineered using digital platforms for structural and fluid multi-physics simulation. High-strength cast iron (or structural steel) provides exceptional redundancy, heat dissipation, and vibration isolation margins. This structural design mitigates severe mechanical shocks and lowers the general running temperature rise of the motor.
Comprising a fan cover body, air guide cylinder, protective window, and silencer plate, the low-noise ventilation system optimizes airflow patterns and absorbs high-frequency noise. Rating at IP22, the design ensures safe operation by preventing human contact with the rotating fan blades while maintaining optimal thermal cooling performance.
Our high-voltage AC motors comply with strict international regulatory standards, ensuring seamless deployment in hazardous locations and heavy engineering projects across Nigeria.

Our selection of specialized high voltage and low voltage machinery for diverse industrial applications in Nigeria.
Purchasing heavy high-voltage industrial equipment in West Africa requires a clear understanding of Total Cost of Ownership (TCO). High-voltage motors are substantial capital investments, meaning operations managers and engineers must look beyond the initial purchase price. The long-term costs of energy consumption, maintenance down-time, and spare parts availability make up over 85% of a motor's lifecycle cost. Because of this, our high-voltage solutions focus heavily on energy optimization, achieving up to IE4 and IE5 efficiency levels.
Additionally, we work closely with local engineering partners and technical teams in Nigeria to provide post-installation guidance. From aligning terminal box specifications (such as customizable phase split options) to providing specialized anti-condensation heaters that keep the motor windings dry during periods of shutdown in wet seasons, our engineering supports long operational lifespans under challenging conditions.
