Premium flameproof and increased-safety motors engineered for refinery terminals, chemical processing, and mining grids.
Your portal to WOLONG Group's world-class electrical drive engineering and global multi-brand consortium.
Why engineers globally choose our custom-designed high-voltage and explosion-proof motors.
With R&D centers in China, Europe, and Japan, alongside our central research institute in Shanghai, we continuously push electromagnetic efficiency limits. Our custom simulation platforms guarantee the best torque density and insulation longevity.
Offering solutions through Brook Crompton, Morley, Laurence Scott, Schorch, and Nanyang Explosion-Proof, we cover everything from standard commercial pumps to nuclear power plant drives and naval marine generators.
Our motors carry complete global certifications including ATEX, IECEx, CSA, UL, and SABS. Engineered with superior structural redundancy, they easily withstand extreme pressure waves and thermal stresses.
Ensuring your capital investments comply with the Energy Act of Kenya and international engineering codes.

A deep dive into the high-grade materials and structural design of our High-Voltage motors.
Rotor construction uses cast aluminum produced through centrifugal or die-casting techniques. For larger capacities, we integrate copper bar rotors featuring welded end rings and protective high-speed shrink rings, ensuring excellent starting torque and mechanical integrity.
Stator coils are wrapped with high-mica tapes and premium polyester films. The entire stator assembly goes through a modern Vacuum Pressure Impregnation (VPI) cycle, creating a moisture-proof, chemically inert, and thermally stable block rated for Class H operation.
Engineered using multi-physics structural and fluid simulation tools. Built with premium structural redundancy to withstand heavy operational shock loads while isolating harmonic vibrations and maximizing cooling airflow.
Features integrated silencer plates and optimized aerodynamics. Side-entry air intakes minimize downstream air turbulence, reducing acoustic noise while maintaining IP22 protection and cooling performance.

Clear, direct answers to common engineering and import questions about industrial motors in East Africa.
Ex d (Flameproof): Designed to contain an internal explosion if gas enters the motor. The flame paths cool the internal hot gases before they can escape to the outside environment, preventing external ignition. This is common in high-risk zones like fuel depots and chemical facilities.
Ex e (Increased Safety): Built to prevent hot surfaces or sparks from occurring in the first place under both normal operation and fault conditions. It relies on high-grade materials and strict insulation standards to prevent ignition, but does not house an explosion. It is commonly used in Zone 2 areas.
High-voltage grids in East Africa can experience voltage drops and frequency variations. Motors connected to these lines must have robust electromagnetic designs and high-grade insulation (typically Class F with a Class B temperature rise limit). This provides a thermal buffer to handle current spikes caused by lower voltages without degrading the winding life.
Yes. Through our YBBPX and related series, we configure complete Variable Frequency Drive packages. Our engineers optimize the motor design and VFD parameters together to prevent harmonic heating, bearing currents (using insulated bearings), and mechanical resonances across the speed range.
Geothermal sites present highly corrosive atmospheres due to wet air and sulfur gases. For these environments, we provide corrosion-resistant paint systems (up to C5-M marine rating), high-durability seals, stainless steel hardware, and positive pressure enclosures (Ex p) to keep ambient gases out of the motor housing.
All Wolong Nanyang motors come with a standard 12-month factory warranty, with options to extend. As an authorized distributor, Shaanxi Nanfang Motor coordinates remote technical support, commissioning guidance, and supplies genuine replacement parts quickly through our global logistics network.
