ESC-500 Horseshoe Clip

ESC-500 Horseshoe Clip (Stirrup Clamp) is a heavy-duty, spring-loaded aluminum alloy connector designed for 10kV live working (hot line) on overhead distribution lines. It enables fast, safe branch tapping, grounding, and testing without power shutdown. The horseshoe/stirrup shape ensures stable hanging and easy installation with a hot stick.

Key Features

• ✅ Live Working Ready: Install/remove under 10kV energized lines; no outage required

• ✅ Spring-Loaded Design: Self-holds on conductor during installation; supports own weight

• ✅ Horseshoe/Stirrup Shape: Stable hanging, easy alignment, low contact resistance

• ✅ Dual Function: Works as tap clamp, grounding ring, or testing ring

• ✅ High-Grade Materials: Aluminum alloy body, tin-plated copper stirrups, stainless steel eye bolts

• ✅ Wide Conductor Range: For aluminum/ACSR overhead wires

• ✅ Hot Stick Compatible: Install with standard insulated operating rod

• ✅ Reusable & Durable: Bolted design for repeated use; anti-corrosion finish
