Product Description
WANGYUAN QP and QH Ball Eye Series are designed for flexible articulated connections in distribution and transmission line insulator strings and suspension assemblies. Made of hot-dip galvanized forged and cast alloy steel, the spherical ball-and-socket interface permits angular movement to accommodate conductor swing and wind deflection. Available in QP and QH configurations with multiple load ratings. All products comply with relevant international standards.

Advantages
Flexible Articulation
The precision-machined spherical ball interface provides smooth multi-axis angular articulation, allowing insulator strings and conductor assemblies to swing freely under wind loads without imposing bending moments on adjacent hardware.
High-Strength Steel
Ball eyes are manufactured through hot forging or precision casting of high-grade alloy steels, achieving dense grain structure and superior tensile strength. Flanged base designs prevent pull-through and provide positive seating within the socket.
Corrosion Resistance
Complete hot-dip galvanizing provides uniform corrosion protection across all surfaces including internal socket cavities. The smooth galvanized surface contributes to corona-free performance at medium and high voltages.
Standard Compatibility
Compliant with international dimensional standards for ball-and-socket couplings, the QP and QH series ensure full interchangeability with industry-standard socket clevises, yoke plates and suspension clamps.
