Allowing for a 3.8m loop inside the closure, mark the centre of the loop and strip 1.9mts each side. Distribution side cable Exchange side cable 4.3 Assemble the strength member clamps on the plate as shown. 4.5 Take the loop insert tool 3A and form the element tubes gently over it. Push the element tubes in the sleeve. The non coated edge of the sleeve (arrow) should be pointed towards the base of the closure. Ensure cable tie ratchet blocks are positioned this side of cable Exchange side cable 4.4 Referring to template in section 9 use Cutter Cable Hand 5 to cut both strength members, clean and abrade cables before installing SCOPs and protection foils. Note: foils have sharp edges, please use with care. Smooth the cable protection foil with a blunt tool. Insert the strength members into clamps and secure using allen key supplied with the port kit & secure cable with tie wraps. 4.6 Still using the loop insert tool pass the tubes through the oval port. 4
5 Heatshrink Installation 5.1 Oval port Note, threaded spacers this side Note, threaded spacers this side 4.7 Install onto the bracket in the oval port and secure with the split pin, open the split pin. 5.1.1 Push heatshrink tubing to top of cable port adjacent with closure base. Insert the 3 fingered clip between the cables. Using a D nozzle start shrinking the tube from the top, continue shrinking and converting the paint until the heat shrink is fully shrunk down. Lightly tape the cables together to prevent them moving during the cooling period. Note: use the heat-shield as required to protect occupied and unoccupied ports whilst shrinking the port seal. 4.8 Store looped elements in the plastic sleeve supplied and store in the dedicated area. Warning; Ensure that any working fibre elements have been positioned behind the loop. 5.1.2 Allow the sleeve to cool for approx 10 minutes before moving. Quality check, all paint converted and a visible flow of adhesive from the clip and at the end of the sleeve 5.1.3 Fill the oval port with Closure Sealant 10B, this provides the required strength for mini cable in the port. 5
5.2 BFT 7 and BFT 12 installation in a Joint box 2 Note, the installation of the flexible tubing shown below is for use in JB2 boxes only. 5.2.1 The above drawing shows two BFT 12s bundles entering a JB 2 from opposite directions, both BFTs have their sheaths removed and replaced with flexible tubing between points A-A and B-B to protect the individual tubes. The length of flexible tube used for A-A is 1380mm The length of flexible tube used for B-B is 900mm. Note, flexible tubes AA & BB are shown in two different shades for clarity. 5.3 Installation of BFT (AA & BB) 5.3.1 Offer the BFT to the FDP (in the working position) ensuring good routing in the joint box. Cut here 5.1.4 All exposed COF 205 must be protected with two pieces of Stayguard 2A yellow intertwined as shown in the picture above. Note: Only one cable shown protected for clarity. 5.3.2. Mark the BFT at a point such that there will be approx 100mm inside the FDP (the100mm will later be trimmed to the required working length inside the FDP). Cut the cable at this point and remove the surplus. 6
For BFT installation in all other Joint boxes. 250 mm 5.3.3. Remove the BFT sheath to a point 250mm from the duct mouth. 5.3.4. Replace the sheath with the required length of flexible tube as shown in 5.2.1. Join the flexible tubing to the BFT cable using a heat shrink port seal kit. Insert the cable sheath into the flexible tubing by 50mm. Then apply foils as shown in 5.3.5 5.3.7 Remove 100 mm of BF tubing sheath. Clean and abrade the BF tubing sheath for a length of 220mm from the cable butt. Position cable protection foils for cables as shown in the templates. Note: foils have sharp edges, please use with care. Smooth the cable protection foil with a blunt tool. 5.3.5. Use a conventional circular port shrinkdown kit, with foils, to secure the flexible tube onto the cable sheath, ensuring the sleeve is central over the flexible tube /BFT sheath. 5.3.6. Ensure the flexible tube extends 20mm into the required FDP circular port at the FDP. Use a circular port shrinkdown kit with foils to secure the flexible tube in position. 5.3.8 Pass cable through heat shrink sleeve. Position cable so as the blue line is at the bottom of the heat shrink tube. See template in section 9 and position heat-shield as required to protect ports. 7
Note: ensure the ARROW on the sleeve points towards the base. The sleeve will not milk off if this is done. Position heat-shield & using a D nozzle start shrinking the tube from the top, continue shrinking and converting the paint until the heat shrink is fully shrunk down. Allow the sleeve to cool for approx 10 minutes before moving. Quality check, all paint converted and a visible flow of adhesive at the end of the sleeve. Note. Fill the port with Closure Sealant 10B, this provides the required blocking of the cable in the port. 5.3.9 Install the BFT into the appropriate port as per section 10. This picture shows a BFT 12 installed into port 4. 5.3.11 When the resin is set, mark and cut all the 4mm tubes at 50mm above the resin. 5.3.10 Fill the port with Closure Sealant 10B, this provides the required blocking of the cable in the port. 5.3.12 Ensure all tubes are capped with 4mm end caps. 8
6 Fibre routing 6.1 From loop storage remove the elements, select the element required, cut element at the mid point. Route the selected element to the element tube holder, mark & remove element tube to expose the fibres from this point. 6.3 On the required HCSC tray open tray 2 to allow routing onto tray 1. 6.2 Install insert into tube holder to hold element(s) in place. Store all remaining elements in loop storage. Route the fibres up the left hand channel. 6.4 Route fibre to inner track for tray 1 as shown, store fibre on the tray, ensure fibre is stored under all tabs including the bar code tab. Check fibres are correctly retained and close tray 2 onto tray 1 9
Routing Fibre onto High Capacity Single Circuit (HCSC) top Tray 2. Route fibre to outer track for tray 2 6.5 Route fibre to outer track for tray 2. 6.6 Route fibre to hinge, pass fibre through hinge and store fibre on tray, ensure fibre is stored under all tabs including the bar code tab. Check fibres are correctly retained. 10
7 Closing the closure 7.2 Closing the latches. 7.3 Use the nylon securing band around the centre of the closure to hold the closure in place. 8 Quality checks Heat shrink port seals installed with arrow UP, paint converted & visible flow of adhesive from end of sleeve Minimum bend radius of cables & fibres maintained Fibre joint & cables labelled correctly. Cable preparation, fibres thoroughly de-greased Fibres clearly identified, routed & stored correctly Check that closure sealant 10B has been used where required as stated in these instructions. 7.1 Ensure all tubes/fibres are secured inside the closure before and during fitting of the dome. To ensure correct orientation of the dome/base ensure the moulded arrows align. Arrows are highlighted in white in picture for clarity.
