It is highly recommended that a tool suitable for the removal of the semi-conductive screen is used to provide a reliable discharge free termination screen point Use a propane gas torch with a soft flame Avoid a pencil like blue flame which is caused by unregulated supply Keep the flame on the move to ensure even shrinkage of all the materials and also helps to reduce scorching Ensure that all components are kept clean and grease free during installation Allow to cool before applying any mechanical strain X Remove Outer Cable Sheath: VOLTAGE 7.2kV 12kV 17.5kV 24kV 36kV INDOOR L 150mm 190mm 250mm 310mm 510mm OUTDOOR L 200mm 270mm 300mm 360mm 600mm LENGTH OF LUG BARREL + 10% X L Table 1 Single Core Armoured Cables If the Cable is Armoured, bonding of the Armours must be completed using the appropriate Armour Earthing kit.

Neither the Seller nor Manufacturer shall be liable for any injury, loss or damage, direct or consequential, arising out of the use or inability to use the product. Before using, User shall determine the suitability of the product for his or her intended use and User assumes all risk and liability whatsoever in connection therewith. 1. Installation Remove the Outer Cable Sheath to the dimensions L + X given in Table 1. Remove any fillers before cleaning and de-greaseing the Cable Sheath below. 30mm 2. Screen Treatment Copper Wire Screen Apply one turn of the Red Mastic Sealant Tape at a point 30mm below the sheath cut (Fig 2). Bend back the Copper Wires and press them into the Tape. Apply one more turn of Red Mastic Tape over this point. The Wires should be twisted together and Bonded to a suitable earth point. Copper Tape Screen Apply one turn of the red Mastic Tape at a point 30mm below the sheath cut (Fig 3). Remove the Copper Tape Screens to a point 40mm above the Cable Sheath cut as shown opposite in Fig 3. Position a Copper Earth Braid onto the Copper Screen and secure with a Constant Force Roll Spring. Ensure the Moisture Block in the Braid is bedded into the Red Mastic and apply one more turn of Tape over this point. Secure the end of the Braid to a suitable Earth point. Note:- A full range of Solderless Earth Bonding kits are available for all Voltages and Conductor sizes. Fig 2 CONSTANT FORCE 40mm 30mm MOISTURE BLOCK Fig 3 PRIMARY INSULATION CONDUCTIVE LAYER 20mm 40mm RED MASTIC CONSTANT FORCE SPRING 3. Conductive Layer Treatment Extruded Conductive Layer Fig 4 Remove the Conductive layer using a suitable Tool to the dimensions shown in Fig 3 and 4. Avoid scoring and damage to the Primary Insulation. Note:- The Screen should be removed leaving a cleanly cut end. Do not roughen the Insulation with Emery Cloth. PRIMARY INSULATION 10mm 10mm STRESS RELIEF TAPE Fig 5 Soluble Conductive Layer Cover the Conductive screen with Non adhesive Tape for 40mm on Wire Screened Cables and 20mm on Copper Tape Screened Cables (see Fig 4). Remove the layer after this point with a suitable solvent until totally clean. Remember to remove the Tape when finished. STRESS RELIEF TAPE 10mm 10mm 4. Apply Stress Relief Tape Fig 6 Remove the release paper, stretch the TS31785Y Yellow Stress Tape to double its length and apply around the end of each Core Screen to cover Copper Tape(if present) and Insulation by 10mm (see fig 5,6). STRESS CONTROL TUBES 5. Stress Control Tubes Position the Stress Control Tubes so that they cover the Earth connection point and the Conductive Screen end. However do not extend past this point onto the Outer Cable Sheath. Fig 7 Shrink the Tubes one at a time starting from the bottom. Ensure the tubes are wrinkle free and have an even wall thickness. 6. Installing Cable Lugs The Cable should be cut to dimension L+X as given in Table 1. Remove the Insulation at X and install the Lug using the appropriate method. L+X X Fig 8 RED SEALANT TAPE Preheat each Lug and wrap two layers of Red Sealant Tape over the Lug barrel and extend onto the Insulation by approx 10mm. Ensure the Tape is applied as shown. Fig 9 7. Installing Anti-Track Tube Position the Anti-Track Tubes so that they overlap the Earth connection point and outer Cable Sheath by 60mm as shown in Fig 10. Shrink the Tubes starting from the bottom towards the top. Keep the flame on the move to ensure an even wall thickness. User may trim the Tubes at the Lug end with a sharp knife if necessary.

Indoor Terminations NUMBER OF SHEDS PER PHASE VOLTAGE INDOOR OUTDOOR 7.2kV 2 12kV 2 17.5kV 2 24kV 3 36kV 1 4 Anti-Track Rain Sheds are not required on Indoor Terminations rated between 7.2 and 24kV. One Shed per phase is required on 36kV types (see Table 2). Clearance Dimensions Minimum clearances should be observed for phase to phase and phase to ground (see Table 3). VOLTAGE (kV) DISTANCE (mm ) 7.2 15 12 20 17.5 20 24 25 36 35 Table 2 Table 3 9. Outdoor Terminations Anti-Track Sheds should be fitted starting from the bottom up as per the dimensions given in Fig 12. The number of Sheds required depends on the system voltage (see Table 2). Fig 11 Positioning of Sheds The first Shed should be fitted at a distance of 200mm from the lower edge of the Anti-Track Tube to the edge of the Shed. All subsequent Sheds should be fitted at a distance of 80mm from edge to edge. Note:- It is advisable not to position Sheds at the top of the Stress Control Tubes. Re-position if necessary. 80mm 200mm Fig 12 Reverse Connection If a Termination is to be mounted for connection above the equipment i.e in the reverse position, Sheds should be installed through 180º. Fig 13 Min Bending Radius r=15xD 10. Cable Bending Radius If required The Cable can be heated to approximately 70ºC to enable a bend to be introduced. See Fig 14 showing the bending radius.
