QH Ball Eye Overview
Engineered for precision and strength, the QH Ball Eye perfectly fits circular joints to seamlessly connect sockets with the main insulator string.
- Constructed from heat-treated, hot-dip galvanized steel, granting the fitting exceptional ductility and structural resilience.
- Features premium connecting bolts configured in grade 4.8 or 8.8.
- Equipped with split pins manufactured strictly from stainless steel or tinned copper.
- Delivers robust short-circuit capability optimized by precise cross-sections and smooth bolt holes (Note: maximum strength is best maintained at standard operating temperatures).
QH Ball Eye Features
Integrating the QH Ball Eye into your power lines guarantees a straightforward, highly dependable installation backed by direct-factory B2B terms:
- Corrosion Protection: The hot-dip galvanized finish completely shields the hardware against environmental rust and long-term wear.
- Custom OEM Manufacturing: Fully supports customized production; simply supply a drawing, photo, or physical sample.
- Order Flexibility: Absolutely no Minimum Order Quantity (MOQ) on any order. Free samples are provided (buyer covers the freight charge).
- Quality & Project Readiness: Manufactured under ISO 9001, 14001, and 18001 standards, featuring low costs, fast quotations, and complete tender documents ready for submission.
QH Ball Eye Applications
Built to safely transmit mechanical loads, the QH Ball Eye acts as a crucial linkage component. It is strictly used for:
- Attaching ball and socket insulators securely to transmission towers and overhead conductors.
- Forming heavy-duty distribution attachments in conjunction with anchor shackles.
- Supporting continuous supply requirements for large-scale LV and MV EPC engineering material lots.
