User manual SHRINK POLYMER SYSTEMS HEATSHRINK TERMINATION FOR 3 CORE POLYMERIC CABLES 7.2KV TO 36KV

[. . . ] This is achieved by positioning the 3 Core Breakout within the body of the Gland which is situated below the Cable Box Gland Plate. IMPORTANT NOTICE TO PURCHASER:- Sellers and Manufacturere's only obligation shall be to replace such quantity of the product proved to be defective. 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. [. . . ] Note:- It is very important that the screen is removed leaving a clean cut end and that no scoring and damage is done to the primary insulation. The smallest `Nick' can produce very high levels of discharge, therefore we highly recommend the use of approved screen removal tools (see page 38 in our general catalogue). Soluble Layer Using either non adhesive tape or tape turned backwards, cover the top of dimension A and remove the soluble layer above using a clean cloth and suitable solvent. Note:- Remember to remove the tape STRESS TAPE 10mm A A It is good practice to flame brush the primary insulation and conductive screen cut. This has the effect of removing any minor surface scratches or burrs that may be present. Apply Stress Control Tape 10mm COPPER TAPE SCREEN Remove the release paper from the TS31785Y Yellow Stress Tape. Stretch and apply the tape around the end of each core screen to cover the copper tape (If present) and insulation by 10mm either way. 4. Stress Control Tubes Position the stress control tubes onto each core so that the bottom of each tube is a distance C from the outer sheath cut as indicated in Table 3. Shrink each tube one at a time and keep the flame on the move to ensure an even wall thickness. C C VOLTAGE 7. 2kV 12kV 17. 5kV 24kV 36kV C 100mm 100mm 100mm 150mm 200mm Table 3 5. Installing Cable Lugs Remove the insulation from each core to the X dimension in Table 1. Install cable lug and remove any burrs or sharp points that may be present. Preheat each lug and wrap two layers of red sealant tape over the lug barrel and extend onto the insulation by approx 10mm. ROLL SPRINGS X 6. Installing The Breakout Boot Slide the three legged boot over the cores and push down into the crutch of the cable. Shrink from the centre of the skirt to the cable sheath and from the turrets to the cores. Apply a turn of red sealant tape around each breakout turret as shown. 7. Installing The Anti-Track Tube Position the anti-track tubes so that they cover the turrets of the breakout boot and the barrels of the lugs. [. . . ] Alternative Screen Preparation If the screens are terminated at a higher point on the cable it offers many advantages:A) Improved clearance dimensions at the top of the stress control tubes. D B) The ability to core cross whilst retaining the required clearances. D) More likelihood of achieving even shrinkage of the materials at the screen cut. Therefore we recommend that the semiconductive screen is removed in accordance with the dimensions shown in the picture opposite and indicated in Table 6. [. . . ]
