On our LV-ABC street-lighting taps, the old method meant stripping the main and rebuilding the joint in the rain. CONWELL IPCs let the crew pierce and torque to the shear head without opening the insulation. The contact stayed tight through the wet season, and we stopped getting callbacks for oxidized branch connections.
We used to mix clamps on the schedule—suspension hardware on terminals, tension hardware mid-span. After standardizing on CONWELL dead-end clamps for terminals and angles, and suspension clamps for straight intermediate poles, the crew BOM became simple. The polymer wedges grip covered conductors without cutting the sheath, which matters on our NFC/EN-style ABC routes.
Rural feeders here see heat, UV, and dust year-round. We needed one accessory set that installers could learn in a day. CONWELL’s aerial range—piercing connectors for services, tension clamps at dead ends, suspension on intermediate poles—cut training time and cut mid-span slip complaints. Less outage time is the metric our client actually pays for.
