Trunnion Helical Cushion Suspension Assembly

The THCSA is a bolted aluminum trunnion suspension clamp. It is designed to provide enhanced conductor support and protection. The THCSA combines a cast aluminum clamp assembly with helical aluminum alloy rod sets and EPDM rubber inserts. The rubber inserts are assembled directly onto the conductor and are held in place with helical rods. The clamp assembly is then bolted around the helical wrapped rubber supporting inserts to complete the trunnion install. Material: Clamp Body-Aluminum Alloy, Rubber Insert-EPDM Rubber, Helical Rods-Aluminum Alloy.
