Product Detail

    Wolong Nanyang's YZYKS series high-voltage positive pressure shell type three-phase asynchronous motors represent a significant advancement in explosion-proof technology. Leveraging advanced foreign technology and combining it with Wolong's extensive experience in high-voltage electric motor design and manufacturing, these motors offer unparalleled safety and reliability. As the first of its kind in China, this technology ensures optimal safety in explosive environments by maintaining a positive pressure within the motor housing. This prevents the ingress of explosive gases, significantly reducing the risk of ignition.
The sophisticated system effectively replaces explosive gases during startup and maintains the necessary positive pressure during operation. The system automatically monitors and adjusts pressure levels, providing reliable protection and timely alerts in case of anomalies. Rigorous design, premium materials, and precise manufacturing processes contribute to the exceptional safety and reliability of these motors. The motors are designed to be compact and lightweight, while delivering high power output, efficiency, and low noise levels. Available in two explosion-proof types (Expx and Expz), these motors are suitable for a wide range of applications in hazardous environments, including those in the petrochemical, chemical, and mining industries. 
By incorporating state-of-the-art technology and stringent quality control, Wolong Nanyang's YZYKS series motors offer a robust and efficient solution for powering critical equipment in explosive environments.

Application
