3M™ 5458A Series Cold Shrink QS-III Splice Kit is an inline splice designed to join 25/28 kV jacketed concentric neutral (JCN) or concentric neutral (CN) power cables. The cold shrink design fits type MV-90 or type MV-105 cables with aluminum conductors while ensuring a quick installation and excellent cable size transitions.

3M™ 5458A Series Cold Shrink QS-III Splice Kit includes an adapter tube, 2 compound tubes, six 2230 sealing strips, two 2228 tape rolls, a neutral/CC-3 cleaning pad, 2 cable preparation templates and an instruction booklet. It has a computer-aided design that provides a compact size and optimal distribution of the electrical field. The cold shrink splice body has a specially formulated silicone rubber construction to ensure good high and low temperature performance. Its jacketing with EPDM rubber construction provides physical protection. The kit is for use with standard inline crimp connectors and meets the requirements of IEEE 404 standards.
