Complete Stay Assembly Selection Guide: NX Wedge to NUT Clamp Matching
Functional Distinctions in Upper and Lower Fittings
A robust stay assembly requires distinct components for anchoring and tensioning. The upper connection relies on dead-end wedge clamps to secure the strand, while the lower section uses UT-type clamps with turnbuckle threads for precise tension adjustment within the guy wire assembly.
NX series wedge clamps dominate the upper attachment point. The sliding wedge mechanism exerts proportional gripping force under mechanical tension. This prevents wire slippage when the assembly guy faces extreme transverse wind loads.
Conversely, NUT series clamps manage lower anchor connections. Threaded rods allow structural adjustments after initial installation. A proper pole stay set utilizes this adjustability to counteract cable sagging over extended operational periods.
Accessory Configuration Requirements
Standardizing the physical framework mandates specific structural hardware pairings to maintain network integrity. Installing proper accessories ensures the tension distribution remains balanced across the entire pole structure.
-
Thimble clevis units actively protect the bending radius from localized friction.
-
Extension rings seamlessly accommodate irregular span distances across challenging structural topographies.
-
Specialized hoops provide the primary rigid attachment interface for structural grounding.
Steel Strand Selection and Matching Matrix
Matching exact galvanized steel strand dimensions ensures secure mechanical holding strength across installations. The table below outlines reliable matching configurations centered primarily around the standard GJ-25 specification.
| Steel Strand Spec | Section Area | Upper Connection | Lower Connection |
|---|---|---|---|
| GJ-25 | 25 sq mm | NX-1 | NUT-1 |
| GJ-35 | 35 sq mm | NX-2 | NUT-2 |
| GJ-50 | 50 sq mm | NX-3 | NUT-3 |
Strength Grading and Equipment Compatibility
It is necessary to strictly verify hardware compatibility across all connected mechanical joints. The ultimate tensile strength of the stay set complete must never exceed the breaking load limit of the main pole hoop.
