1.0 Introduction
This bulletin outlines the procedure for Jointing and branching procedure for Piggyback Drop duct
Dura-line has always been a pioneer in developing new ducting technologies for deployment in non-traditional ways. Piggyback drop duct is the latest addition to our broad portfolio of alternative rights-of-way solutions.. Piggyback Drop Duct™ is a multi-pair service wire and/or coaxial F-dropwire "piggybacked" on permanently lubricated SILICORE™ drop duct. One step installation provides current service wire drop needs and a SILICORE™ permanently lubricated path for future coaxial or fiber optic upgrades as well as for service restoration. Any customer-specified service wire may be combined with any drop duct size. Usable with all currently deployed plows. The SILICORE™ lining provides permanent lubrication for ease of cable placement in future years.
One –step installation provides current service wire drop needs and a SILICORE™ permanently lubricated path for future upgrades to fibre as well as for service restoration. Any customer-specified (2, 3 or 5-pair) service wire may be combined with any drop duct size usable with all currently approved cable plows SILICORE™ lining provides permanent lubrication for ease of placement in future years.

Features Accommodates current service drop needs and provides a permanently
lubricated path for upgrades or service restoration Any size drop duct may be combined with any size drop wire SILICORE™ permanent lubrication Sequential footage markings Rugged HDPE construction Available empty or with preinstalled pull line Standard wire preparation and termination techniques used Available with single drop wire on duct (as shown) or 2 drop wires in stacked
configuration.

If any cut occurs, we require following given tools to repair micro ducts, micro cables -
Tools
2.1 Simple Duct CutterSimple duct cutter with sharp cutting blade makes a fast, clean and burr-free cut in ducts.
2.2 Rotary Duct CutterIt is used for making perfectly straight, clean and burr-free cut in ducts up to 63 mm size to facilitate leak-proof coupling.
2.3 Armored Cable Cutter:
Utilized for cutting of Armour in OFC cables. Cable can be easily loaded in to tool. Adjustable cutting depth prevents damage to the Fibre
insulation. Long lasting high-speed steal blade improves
productivity.
2.4 Micro duct straight cutterThis cutter differs from the straight cutter in that it cuts just the Micro Duct itself, not the Micro Cable inside.
Figure 2.4
2.5 Micro duct round cutterThis cutter gives a very nice 90-degree cut, which is required at the Micro Duct splice point.

2.9 Heat Shrink Rubber
This is semi flexible, heat shrinkable tubing with melt able adhesive inner lining designed to provide moisture proof sealing to a wide range of substrates such as electrical wire splices, cable jackets, wire breakouts and electrical components. The high shrink ratios mean that only seven sizes are required to cover a wide range of substrate diameters. Typical applications are environmental sealing of electrical components including wire splices and harness breakouts as well as sealing cable ends against moisture ingress.

3.0 Case Study
3.1 Joining of Piggy Back with Service wire, Co-axial Cable, Micro Duct and Normal Duct3.1.1 Normal Duct preparation & Joining
Get Normal duct out from the piggyback duct.
Insert one part of duct in push-fit coupler, insert another part of duct from another side of same coupler till marked line
3.1.2 Micro duct preparation & Joining
Remove micro-duct out from the piggyback duct.
Make 90 degree cut on micro-duct by Micro-duct Straight Cutter.
Insert one part of micro-duct in Micro push-fit coupler till line given on push-fit coupler; insert another part of micro-duct from another side of same coupler till marked line.
Check push-fit coupler’s grip on micro-duct.

3.1.3 Service wire Preparation & Joining
Remove service wire from Piggyback duct.
Join both end of service wire by using service wire repair kit.
Use tape over joint.
3.1.4 Co-axial Cable preparation & Joining
Remove Co-axial cable from Piggyback duct.
Join both end of Co-axial cable by using their repair kit.
Use tape over joint.
3.1.5 Joining of Piggy Back
The Co-axial cable, service wire and Micro Duct on Piggyback Duct is lightly bonded to the drop duct and is easily removed for wire preparation. Colored over sheath is easily removed from wire and does not interfere with normal wire preparation.
Once you join all Normal Duct, Service Wire Cable, Co-axial Cable and Micro Duct, Use tape to combine all said ducts and cable. Install heat shrink sleeves for making joint, waterproof. Do not forget using of aluminum foil to avoid excessive heating, which may cause to damage piggyback duct.
3.2 Joining of Piggy Back with Service wire and Normal Duct
3.2.1 Normal Duct preparation & Joining
Get Normal duct out from the piggyback duct.
Insert one part of duct in push-fit coupler, insert another part of duct from another side of same coupler till marked line
3.2.2 Service wire Cable Preparation & Joining
Remove service wire from Piggyback duct.
Join both end of service wire by using service wire repair kit.
Use tape over joint

3.2.3 Joining of Piggy Back
The service wire on Piggyback Duct is lightly bonded to the drop duct and is easily removed for wire preparation. Colored over sheath is easily removed from wire and does not interfere with normal wire preparation
Once you join all Normal Duct and Service Wire Cable, Use tape to combine all said ducts and cable. Install heat shrink sleeves for making joint, waterproof. Do not forget using of aluminum foil to avoid excessive heating, which may cause to damage piggyback duct.
3.3 Joining of Piggy Back with Micro Duct and Normal Duct
3.3.1 Normal Duct preparation & Joining
Get Normal duct out from the piggyback duct. Insert one part of duct in push-fit coupler, insert another part of duct from
another side of same coupler till marked line
3.3.2 Micro duct preparation & Joining
Get micro-duct out from the piggyback duct.
Make 90 degree cut on micro-duct by Micro-duct Straight Cutter.
Insert one part of micro-duct in Micro push-fit coupler till line given on push-fit coupler; insert another part of micro-duct from another side of same coupler till marked line.
Check push-fit coupler’s grip on micro-duct.
