Midspan joints
The midspan joint is mainly used for joining the pieces of two conductors together. For all the conductors having a diameter greater than 14.16 mm, Rayphen mid span compression joint is used. These compression joins not only provide a reliable connection but also give mechanical and electrical continuity to the conductors.
