3M 7000031458 Cold Shrink Insulator Splice 1 Kv

Product Description

The 3M 7000031458 is a cold shrink insulator splice designed for secondary cable splicing applications rated up to 1 kV. Supplied prestretched on a removable core, the unit installs without heat tools or open flame. Once positioned, the installer unwinds the core and the tube contracts under its own live memory action, forming a moisture-tight environmental seal around the splice. The specially formulated material provides permanent insulation and durable protection against moisture intrusion. This splice meets the requirements of ANSI C119-1 and Western Underground Guide 2.14 for secondary splices, making it a code-compliant choice for low-voltage underground and shielded cable work.

This cold shrink insulator is suited for use on Unishield tape and wire secondary splice applications at 1 kV and below. It is appropriate for residential and commercial underground distribution work where a reliable, long-term environmental seal is required on secondary conductors. Electricians and utility lineworkers install this product during new construction and repair of underground secondary cable runs.

Key Features

• Rated for secondary splices up to 1 kV per ANSI C119-1 and Western Underground Guide 2.14
• Cold shrink delivery system requires no heat gun, torch, or flame to install
• Prestretched on a removable core for fast, repeatable positioning
• Live memory action of the formulated elastomer maintains constant radial pressure for a permanent moisture-tight seal
• Compatible with Unishield tape and wire cable constructions at this voltage rating

Compatibility

Designed for use with Unishield tape and wire secondary cable splices rated up to 1 kV, meeting ANSI C119-1 and Western Underground Guide 2.14 requirements for secondary splice applications.

Installation Notes

Installation is performed by licensed electricians or qualified utility personnel in accordance with applicable NEC requirements and local codes governing underground secondary splicing. De-energize and verify the absence of voltage on all conductors before beginning splice work. Position the cold shrink tube over the prepared splice area, then unwind the removable core to allow the tube to contract into place — do not cut or tear the core. No heat source is required or recommended for this product.
