Fitting the Clear Shrink Sleeves With a clean dry cloth, carefully remove any Grease from the Cores. Position the Clear Shrink Sleeves over each Core approx 50mm up from the Cable Crutch. With a suitable heat sourse, shrink the end's of the Sleeves for about 50mm, before fully shrinking, rotate the Sleeves and push down into the Crutch. Note: Ensure there are no air voids and the Sleeves are wrinkle free, also note that excessive heat may dry out and damage the Paper Insulation.
CLEAR SHRINK SLEEVES
Fitting the Stress Control Tubes Position the Stress Control Tubes onto the Cores at a distance of 50mm up from the Metal Sheath Cut. Shrink the Tubes one at a time, starting from the bottom working upwards. Ensure that the Tubes are evenly shrunk and aligned.

With tension, wrap the Grey Mastic Tape around the Crutch area and overlap the Stress Control Tubes and Lead or Aluminium Sheath by approx 10mm. Note:- Ensure that the space between the Bell of the Lead Sheath and the entire area between the Cores is fully covered by the Mastic tape to eliminate Air Voids. With a suitable solvent, clean the Metal Sheath before proceeding.

4. Installing Cable Lugs
X
Allowing for dimension X (Lug Barrel + 5mm), cut the Cores to suit the fixing point on the equipment being used. Measure a distance of X (See Table 1) back from the end of each Core and remove Insulation.
L + 200mm
With a suitable tool, install Cable Lugs ensuring that any sharp points are removed. Note:- Where Mechanical Connectors are to be used, user should check that the Core Tubes are able to slide over prior to fitting.
5. Installing Anti-Track Tube
Preheat each Cable Lug and wrap two layers of Red Sealant Tape over the Lug Barrel extending onto the Insulation by approx 10mm. [. . . ] If a termination is to be mounted for connection above the equipment i. e in the reverse position, sheds should be installed 0 through 180 as shown.
7. Core Crossing
Screened Cable If the Cores on a Paper Screened Cable have to be crossed, ensure that the cross takes place within the screened area below the Stress Control Tubes.
STRESS CONTROL TUBES FITTED IN A HIGHER POSITION
Belted Cable Core crossing on Belted construction is not recommended unless the minimum clearances are achieved (See Table 2). Note:- Core Crossing/Improved Clearance kits utilising Heatshrink Conductive Tubings can be supplied if requested. [. . . ]
