3M™ 5457A 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.
Inline splice for joining jacketed concentric neutral (JCN) and concentric neutral (CN) power cables
Special electrode design of the kit reduces the electrical stress at a critical cable/splice interface
Designed for inline splicing, feeder and distribution circuits, size transition splicing, direct burial installations and submerged locations
Cable has 1.07 to 1.7-in insulation O.D.
Accommodates 250 kcmil size aluminum conductors
Silicon rubber-splice body provides good high and low temperature performance, and the EPDM rubber jacket offers physical protection
Rated for 25/28 kV cables
High-voltage, production-tested for partial discharge and AC ensure reliability
3M™ 5457A 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, cable preparation template 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.
