User manual SHRINK POLYMER SYSTEMS HEATSHRINK JOINT TO SUIT SINGLE CORE 7.2-36KV POLYMERIC CABLE TYPE SPAJ

[. . . ] If the Cable is Aluminium Wire Armoured expose Armours by 40mm and Inner Bedding by 35mm (See section 22-24 and Fig 13-14). Bend back the Wires onto the Outer Cable Sheath, these will be bonded at a later stage. Expose the Black Semi-Conductive Screen by 80mm (See Fig 1 and Table 1 for dimension A dependant on voltage class). Braided/Woven Copper or Phosphur Bronze Screen 4. [. . . ] Before proceeding, position the Connector Insulation Tubes down one or both of the Cables ends if the Tubes do not "Nest"as shown in Fig 3. Note:- Picture shows one GMT Tube making the Joint suitable for 17. 5 and 24kV. For 12kV, only TCC Stress Control and GIS combined Insulation/Conductive Tubes are required. GIS Fig 3 GMT Stress Relief 8. Remove the Primary Insulation for ½ length of the Connector + 5mm. Crimp the Connector with the correct Tool/Die and remove any sharp burrs. STRESS TAPE 10. De-grease the Connector and Primary Insulation with the Tissues provided. Apply the Yellow TS 31785Y Stress Tape over the Connector with half width overlap and double stretch. Important:- Fill in the gap between Primary Insulation and Connector and extend onto the Primary Insulation by 15mm only. If Reducer Ferrules are used to join different Conductor sizes, ensure Stress Tape is "Tapered" from Connector to the Insulation. 15 15 Fig 4 10mm 15mm 12. Stretch the Yellow TS 31785Y Stress Relief Tape to double its length and apply with ½ width overlap around each Black Semi-Conductive Screen edge so that it overlaps for a distance of 15mm onto the Copper Tapes or Lead Sheath and the Primary Insulation by 10mm as shown in Fig 5. Fig 5 Connector Insulation Tube Sequence 13. Position the Stress Control Tube (TCC) centrally over the Connector overlapping the end of Screen points and onto the Copper Tape Screens (If present) or Lead Sheath. With a suitable heat source, shrink from the centre working all around the Tube to one end at a time. Note:- Allow the Tube to cool before cleaning the surface with the Tissues provided (This improves electrical performance). GIS TCC Fig 6 14. If voltage is higher than 12kV position the required number of Red GMT Tubes one at a time, centrally over the Stress Control Tube and shrink in an even manner (See Table 1 for Tube requirement). GIS Fig 7 15. Position the Combined Insulation/Conductive Tube (GIS) centrally over the Stress Control Tube (Or Red GMT Tube depending on voltage) and shrink as previous. Keep the flame on the move to ensure an even wall thickness. 4SC HV GREY TAPE GIS 20 16. Take the two pieces of 4SC HV Grey Mastic Tape and apply whilst stretching to the ends of the GIS Tubes and Copper Tape Screens (If present) or Lead Sheath by approx 10mm each as shown in Fig 8. Fig 8 Screening - Copper Tape Screen KM 50 COPPER SCREENING BANDAGE DWHV DWHV SCT Fig 9 ROLL SPRING 17. Wrap two layers of Copper Screening Bandage (KM 50) with 50% overlap over the Joint area and secure to the Copper Tape Screens or Lead Sheath by either Soldering or the preferred Roll Spring method. Screening - Copper Wire Screen DWHV SCT Fig 10 BINDING WIRE 18. Wrap a layer of KM50 Copper Screening Bandage over the joint area and secure. [. . . ] Secure to both ends with the Clamps provided. Apply the remaining pieces of 212D Black Tape over the Clamps and any sharp points as shown in Fig 14. Note: Depending on length of Connector used which effects the joint gap, user may need to trim the Cage 212 D MASTIC TAPE 24. Refer back to section 20 and Fig 12 for the installation of the Outer Shrink Tube.
