Overview

The ABB GTC13 copper tower ground clamp is a one-piece grounding solution designed for direct attachment to tower structures. Constructed from high-strength, corrosion-resistant copper alloy, it provides a durable and low-resistance connection for grounding applications. The clamp accommodates wire ranges from 4 AWG to 2/0 stranded copper, with a maximum conductor cross-section of 67.4 mm² and minimum of 21.1 mm². Its compact design features a ¼-inch channel thickness and dimensions of 1 15/32 inches (A), 9/16 inches (D), 1 17/32 inches (E, G), and 7/8 inches (H). The square shank bolt prevents rotation during tightening, enabling single-wrench installation. Ideal for grounding substations, tower footings, and other structural applications where direct conductor-to-tower grounding is required. Compatible with both aluminum and copper conductors, the GTC13 eliminates the need for under-pad support, reducing installation time and material costs. The clamp's robust construction ensures long-term reliability in outdoor and industrial environments.
