Overhead Line Fittings

JB Aluminum Alloy Parallel Groove Clamp for Overhead Conductors

Product Overview

JB is presented as an aluminum-alloy parallel-groove clamp family for overhead conductor connections. The gallery shows two- and three-bolt clamp bodies, while the existing page lists JB-1 through JB-6 without a model-by-model conductor fit table. Confirm the chosen model, conductor construction and diameter, groove profile, tightening torque, electrical duty and installation procedure from its current drawing and test records. Energized-line use requires a separately approved method and qualified crew.
