OLTC Coupling hub

Coupling Hub ? Product Description

The Coupling Hub is a precision-machined mechanical component used to connect and transmit torque between two rotating shafts in tap changer and motor drive assemblies. It ensures accurate power transmission while maintaining proper shaft alignment, reducing stress on connected components. This component plays a vital role in ensuring smooth and efficient operation of transformer drive mechanisms.

Manufactured from high-grade steel or alloy material, the coupling hub offers excellent strength, wear resistance, and long service life. Its robust construction minimizes vibration, absorbs minor misalignment, and enhances overall mechanical reliability under continuous operating conditions.
