TRANSCRIPT
Single Core Cable Termination System
Raychem Heat-Shrinkable Termination System for Cables up to 36 kV
Polymeric or Paper Insulated Cable Outdoor Service rain skirts installed over non-tracking sleeve otherwise, installation is the same as for an indoor termination
Paper Insulated Cable (Mass Impregnated, Non-Draining) Indoor Service oil barrier, insulating tubing (clear) installed over paper insulation otherwise, installation is the same as for a polymeric insulated cable
Polymeric Insulated Cable Indoor Service void filling compound stress control tubing non-tracking sleeve with sealant layer It’s the same system for all types of polymeric cable
Three Core Cable Termination System
three-core breakout installed at end of cable oversheath otherwise, installation steps are the same as for three single core Terminations The Raychem termination system is compatible with all types of armoured cable. The system includes a complete range of solderless accessories for earthing insulation screens and cable armour and for grounding lead sheaths. Also available are insulators and support brackets, insulating boots for equipment connections and glands for easy entry to cable boxes. For more details please refer to the EPKT (EPP-0282/2) and I(O)XSU-F (EPP-0795 & 0782) Termination brochures. You can ask for our capability brochure (EPP-1102) that exhibits all product families.

Design and construction
RSTI - Screened, separable connection system 630 A up to 24 kV
1 Screened body A thick-walled moulded conductive outer screen is permanently bonded to the silicone rubber insulating material of the body. 2 Inner screen A conductive inner layer, as a faraday cage around the compression or mechanical lug, prevents corona at rated voltage. 3 Compression or mechanical lugs Specially designed DIN and deep indent compression lugs, as well as mechanical lugs with shear bolts for connecting either aluminium or copper conductor cables. 4 Stress cone adapter Relieves electrical stress at the point where the cable screen is cut. The insulated section, extending beyond the wire shielding, provides a convenient point for oversheath testing. 5 Earthing eye and ground lead Provides a connection point for earthing the screen. 6 Threaded pin A threaded pin together with a spring washer and hex nut ensure a high-performance electrical and mechanical contact with the bushing. 7 Rear plug with test point Removable rear plug with capacitive test point. 8 Test point The test point is used to determine whether the circuit is energised; alternatively it can be used for phasing. 9 Conductive endcap Electrical screen and protection of the rear end of the separable connector
