Insulated splices

This video discusses the core features and key benefits of Eaton’s Cooper Power series insulated splices.

EZ II splice one piece design

The design features of the EZ II splice including the tapered cable entrance, smooth bore, relieved conductive insert and reformulated rubber provide for easier field installation. EZ II splices have been shown to be 30% easier to install than other splices.

Easy to install EZ II splice for fully submersible use

15, 25 and 35 kV class one-piece EZ II splice provides a permanent, fully-shielded, fully submersible, easy to install cable joint with a current rating equal to that of the mating cable.
