3M 7000031370 Copper Barrel Connector 2 Awg 35 Kv

Product Description

The 3M 7000031370 is a copper standard barrel connector rated for use up to 35 kV on copper conductors only. Sold individually, this connector is constructed from one-piece, seamless, high-conductivity copper for reliable electrical continuity in medium-voltage splicing applications. It accommodates 2 AWG conductors and features a 0.307-inch inner diameter and a 0.416-inch outer diameter, with an overall length of 1.880 inches. Electricians and utility technicians working on medium-voltage cable systems rely on this connector for clean, low-resistance inline splices.

This connector is suited for medium-voltage electrical installations where copper-to-copper conductor splicing is required. Its seamless barrel construction makes it appropriate for use in underground residential distribution, commercial power distribution, and utility service applications where voltage integrity up to 35 kV must be maintained. It is intended for use with copper conductors only and should not be applied to aluminum wiring.

Key Features

• Rated for use up to 35 kV for medium-voltage applications
• One-piece, seamless construction eliminates weak points along the barrel
• High-conductivity copper material ensures low-resistance connections
• Accepts 2 AWG copper conductors
• Inner diameter of 0.307 inches and outer diameter of 0.416 inches for consistent fit
• Overall length of 1.880 inches for compact inline splicing

Compatibility

Designed for use with 2 AWG copper conductors only in medium-voltage cable splicing systems rated up to 35 kV. Not suitable for aluminum conductors.

Installation Notes

Installation should be performed by a licensed electrician qualified for medium-voltage work. De-energize and verify absence of voltage on all conductors before beginning any splice work, following applicable NFPA 70 (NEC) safety procedures. Use only manufacturer-approved tooling and follow the connector manufacturer's installation instructions for proper compression or termination method. Do not use this connector on aluminum conductors.
