Ensure the Cables overlap before preparing to the dimensions above and in accordance with the Table below for Conductor size. Remove Copper Tape Screens for a distance of 220mm + ½ Connector length + 5mm. [. . . ] Wrap the Yellow Stress Tape (TS 31785Y) around the Connector area with stretch and ½ width overlap. Also fill any voids that the Bolts leave after they have been sheared. 11. Apply one piece of TS 31785Y Yellow Stress Tape with stretch and half width overlap to each Screen end as shown in Fig 6. Overlap the Tape onto the Copper Tape Screen and Primary Insulation by 10mm either side. 10 10 Fig 6 ONLY ONE CORE SHOWN FOR CLARITY SCT BTT = BLACK STRESS CONTROL TUBE = RED INSULATION TUBE HEATSHRINK TUBE REQUIREMENT PER PHASE VOLTAGE SCT BTT DWMV 7. 2kV 1 --1 12kV 1 --1 17. 5kV 1 1 1 24kV 1 1 1 36kV 1 2 1 DWMV = COMBINED INSULATION/CONDUCTIVE TUBE Table 2 12. Position the Stress Control Tubes (SCT) centrally over the Connectors overlapping the end of Screen points and onto the Copper Tape Screens. With a suitable heat source, shrink all three Tubes at the same time, starting from the centre, working all around the Tubes to one end at a time. Note:- Allow the Tubes to cool before cleaning the surfaces with the Tissues provided. This improves electrical performance. BTT Fig 7 SCT BTT Fig 8 13. Dependant on Voltage class (See Table 2), shrink the required quantity of Red BTT Tubes centrally over the Stress Control Tubes. Two BTT Tubes are required at 36kV, one at 17. 5-24kV with none being required at 12kV or below. Finally position the DWMV combined Red Insulation/Semi Conductive Tubes and as before, shrink into place and ensure an even wall thickness is obtained. Take the six pieces of 4SC HV Grey Mastic Tape and apply to the ends of the DWMV Tubes and Copper Tape Screens by approx 10mm each as shown in Fig 9. 4SC HV GREY TAPE DWMV 20 Fig 9 KM 50 COPPER SCREENING BANDAGE 15. Wrap the Copper Screening Bandage (KM 50) with slight overlap on each Core extending onto the Copper Tape Screens by approx 50mm and secure with Binding Wire. Secure the six Earth Braids to the Copper Tape Screens with the Constant Force Springs provided (The Braids will be clamped to the Armours at a later stage). Fig 10 BINDING WIRE 17. Bend back the Armour Wires and apply 212D Black Mastic Tape onto the Bedding directly under the Sheath cut (SWA only). ARMOUR SUPPORT RING 18. Position the Armour Support Rings and fold back the Armour Wires upon them. [. . . ] Allow the completed Joint to cool before applying any mechanical strain.
