3M™ 5775A-MT Series Resin QS-III Inline Trifurcating Cable Splice Kit is designed for splicing 5/8 to 15 kV-rated shielded power cables. The cold shrink design ensures a quick installation and cable size transitions. This armored or non-armored splice kit is perfect for use in cable trays, cable racks, junction boxes and cable hangers, as well as aerial and wet or dry locations.

3M™ 5775A-MT Series Cold Shrink Resin QS-III Inline Cable Splice Kit includes 3 metallic shield sleeves, 6 small and 2 large constant force springs, 2 cold shrink jacket tubes, 1 roll Scotch-Seal™ mastic tape 2229 and more. This cable splice kit uses constant force springs for connecting ground braid jumpers, splice bodies and tapes for moisture-seal applications. The splice body has a specially formulated silicone rubber construction to ensure optimal high- and low-temperature performance. This splice kit is suitable for use with solid dielectric cables such as XLP, XLPE, EPR and more. IEEE Approved.
