Overview

The ABB HLC Series Hot Line Clamp, SKU HLC3974AP9-2, is a specialized connector designed for overhead power distribution applications. Constructed from durable aluminum and featuring a tin-plated finish for enhanced conductivity and corrosion resistance, this clamp is built for reliable performance in electrical systems. The clamp is Contax filled, ensuring a low-resistance connection and preventing oxidation at the contact points. This hot line clamp is engineered for front tap connections, utilizing a 3/4" nut for secure mounting. It accommodates a wide range of conductor sizes, making it versatile for various utility and industrial needs. The main conductor range supports stranded conductors from 400 KCMIL down to 6, and solid conductors from 185 sq mm down to 16 sq mm. For ACSR conductors, the main range is 397-5 to 6 ACSR. The tap conductor range is equally extensive, designed for stranded conductors from 4/0 down to 6, and solid conductors from 95 sq mm down to 16 sq mm. For ACSR conductors on the tap side, the range is 3/0 to 6 ACSR. Key specifications include: - Manufacturer: ABB - Installation Products - Series: HLC - Material: Aluminum - Finish: Tin-Plated - Connection Type: Hot Line Clamp - Mounting: 3/4" Nut - Main Conductor Range (Stranded): 400 KCMIL - 6 - Main Conductor Range (Solid): 185 sq mm - 16 sq mm - Main Conductor Range (ACSR): 397-5 - 6 ACSR - Tap Conductor Range (Stranded): 4/0 - 6 - Tap Conductor Range (Solid): 95 sq mm - 16 sq mm - Tap Conductor Range (ACSR): 3/0 - 6 ACSR This clamp is suitable for use where live line maintenance or connections are required, offering a secure and electrically sound method for joining conductors. The Contax filling is crucial for maintaining connection integrity over time, especially in environments prone to atmospheric contaminants. The tin plating further aids in establishing and maintaining low contact resistance, vital for efficient power transmission and minimizing energy loss. The HLC series from ABB Installation Products provides a dependable solution for critical electrical connections.
