3M 5318 Splice Kit for 250 kcmil Motor Leads

The 3M 5318 kit provides a complete solution for splicing 250 kcmil motor lead cables rated up to 8000 V. It is designed for electrical professionals who need reliable, non-shielded cable connections in industrial or commercial environments. Each kit contains materials for three separate splices.

EPDM Rubber Body with Copper Contacts and Included

The splice body uses EPDM rubber insulation for heat-shrink application, while the contact material is copper. The package supplies locking pins, mastic sealing strips, pigtail lug covers, Scotch linerless rubber splicing tape 130C strips, silicone grease tubes, solvent cleaning cloths and instruction sheets. Maximum operating temperature is 194 degrees F.

Replaces Field-Assembled Tape Splices

This kit replaces labour-intensive tape-and-mastic splices on 250 kcmil motor leads, cutting installation time and improving seal consistency. The jump is worth it when crews need a repeatable, pre-measured splice for pigtail connections on non-shielded cable up to 8000 V.

Questions about this item

What voltage does the 8000 V splice kit handle in practice?

The kit is rated for 8000 V and uses EPDM rubber insulation to maintain that rating on motor lead cable splices.

What cable size fits the 250 kcmil maximum?

It accommodates motor lead cable up to 250 kcmil with the included pigtail lug covers and locking pins.

How is the 130C splicing tape applied and what step is often missed?

Wrap the linerless rubber splicing tape over the cleaned conductor, then install the mastic sealing strips and heat-shrink body; skipping the solvent cleaning cloths leaves contamination that breaks the seal.
