General Tips & Instructions When Installing Joints and Terminations
Tips and instructions
- This product should be installed by competent personnel familiar with electrical equipment and safe operating practices.
- Part contained in the kits should be visually inspected for possible damage and installed in accordance with the installation instructions. These instructions are not intended as a substitute for adequate training and experience in good safety practices.
- Always keep the work area and cables as clean as possible.
- Use a “clean burning” torch, e.g. A Propane gas torch which does not have any deposits of conductive contaminants.
- Adjust the torch to a soft blue flame with an orange/yellow tip, “pencil-like” blue flame should be avoided.
- Keep the torch aimed in the shrink direction to pre-heat the material.
- Always apply the heat circumferentially around and outwards on all tubes, this ensures correct heat application which results in the correct material wall thickness.
- As the heatshrink has a very thick wall the torch/flame has to be moved continuously to ensure proper shrink and avoid damage due to overheating in one place.
- Shrink the tubing and molded parts as recommended and indicated in the instructions.
- If the tubing needs to be cut, always wait until the tubing has cooled down and then cut with a sharp knife ensuring that there are no jagged edges on the tube.
- Once shrunk, all of the tubing should be smooth and free of any wrinkles.
- Read all instructions carefully before commencing.
Signs of wrinkles indicates incorrect heating and possibly air entrapment.
Cable Preparation Tips
- Cable ends should have been sealed (End Caps) and checked for moisture before proceeding with any work.
- Always keep the cable outer sheath clean and free from dust and mud.
- Take extreme care not to nick or cut the core insulation when removing the outer sheath, copper tape screen and semi-conductive layer on a XLPE cable.
- Do not nick or cut the paper core insulation when removing the belt papers on PILC cable.
- Ring cuts on the copper tape screen and semi-conductive core screen must leave smooth edges (not jagged). Never cut too deep when ring cutting the semi-conductive screen layer on an XLPE cable.
- Tiny nicks in the XLPE insulation and persistent carbon particles can be removed by lightly abrading with non-conductive silver oxide abrasive paper.
- Only use the pre-soaked cleaning cloth/wipes supplied.
- When cleaning the XLPE insulation take extreme care not to wipe the semi-conductive layer as this will contaminate the XLPE surface.
- Clean and de-grease all surfaces that will come into contact with mastic and tubing.
- Take extreme care not to nick or cut the cable insulation when removing the lead sheath and metalised screen paper of a PILC cable.
- Always leave a slight “bell” at the ring cut-off on the lead sheath of a PILC cable.
- Take care not to over bend any of the cable cores to avoid the paper screen or paper insulation cracks.
- Always clean and abrade the surfaces of the lead sheath, to remove the oxidised layer, prior to installing any earthing to the lead sheath.
Always abrade circumferentially around the core insulation.
