PG Clamp For Wolf Conductor

JBB-2 Cast Iron PG Clamp for Transmission Tower Guy Wires (Wolf Specification)

Precision-engineered for high-tensile steel strands with outer diameters of 7.5–11.0 mm, this heavy-duty JBB-2 PG Clamp is explicitly designed for parallel conductor connections and stay-wire anchoring on 11kV/33kV utility lines. It serves as an exceptional mechanical solution for T-connections and parallel splicing on rural networks, power transmission line towers, and lightning protection systems. Featuring a rugged malleable cast iron body secured by high-strength fasteners, its robust dual-bolt locking mechanism ensures uniform, powerful clamping force and effortless field installation.

JBB-2 PG Clamp For Wolf Conductor

Steel Cable Compatibility: The groove curvature is explicitly calibrated for galvanized steel wires and guy lines ranging from 7.5 mm to 11.0 mm in outer diameter, maximizing contact friction to eliminate micro-slippage.

Dual-Bolt Engineering: Built with dimensions of B=50 mm, M=16 mm, L=93 mm, R=6 mm, featuring a 2-bolt structural design that ensures heavy clamping torque without flattening the strands.

Heavy-Duty Solid Weight: Weighing a substantial 1.0 kg per unit, its dense gray iron structure provides elite structural rigidity to withstand fierce wind loads and line vibrations.

Premium Features of JBB-2 Malleable Cast Iron PG Clamps

High-Tensile Malleable Iron Body: Cast from premium-grade malleable iron, offering incredible yield strength, impact toughness, and resistance to structural deformation under massive bolt torque.

Precision-Milled Clamping Grooves: The dual grooves undergo precision sand-casting and post-mold milling to perfectly cradle 7.5-11.0mm steel wires, distributing clamping force evenly to prevent thread damage or wire fraying.

All-Weather Hot-Dip Galvanizing (HDG): Both the iron clamp body and the heavy bolts feature a thick, industrial-grade hot-dip galvanized coating that shields the assembly from heavy rain, humidity, and long-term outdoor atmospheric oxidation.

Utility-Approved Performance Standards: Fully compliant with international electric power fittings criteria (GB/T 2314, GB/T 2315, DL/T 764). Thoroughly verified via factory slip-load tests to ensure dependable, fail-safe performance on overhead lightning protection networks.
