Harger GO3429B Exothermic Welding Mold

Description:

The Harger UltraWeld GO3429B Mold is a graphite exothermic welding mold designed to create a permanent electrical connection between a #29 lightning protection conductor (LPC) and a 3/4-inch copper-clad ground rod. Commonly installed in lightning protection systems, grounding grids, substations, telecommunications facilities, and utility power installations requiring a horizontal through-cable to top-of-ground-rod connection. Electrical contractors and maintenance technicians use this mold to produce low-resistance, corrosion-resistant grounding connections that require no mechanical fasteners.

Applications:

The Harger UltraWeld GO3429B Mold is commonly used in commercial buildings, industrial facilities, telecommunications towers, renewable energy installations, and electrical substations where permanent grounding and lightning protection connections are required. Designed for exothermic welding, the mold provides consistent, high-conductivity connections between a #29 lightning conductor and a 3/4-inch copper-clad ground rod, ensuring long-term electrical reliability and compliance with grounding standards.
