1 What is a Fabric innerduct and why even use one? Archie Booker MaxCell Southwest Territory Manager archie.booker@milliken.com July 28, 2015

2 Two main types of Innerduct Rigid Innerduct Flexible Fabric Innerduct

3 What is a Rigid Innerduct? Manufactured out of High Density Polyethylene (HDPE). Designed for 3 to 4 innerducts within a 4 conduit. Can be used in 3 conduit, but not effectively. Typical deployment is placing 3 x 1.25 in a 4 conduit. Historical construction method.

4 What is a Flexible Fabric Innerduct? Manufactured out of fabric. Designed for placement in multiple size conduits. Maximizes space in a conduit.

5 Why use innerduct? Cables can be damaged by pulling cable over cable and by the pull tape or rope used on the install. Innerduct provides separation or pathways that substantially reduce potential damage.

6 MaxCell Flexible Fabric Innerduct Basics Material: Engineered Nylon & Polyester textile Material Color: MaxCell is white Color Options: Color for MaxCell refers to a tracing thread along the primary seem. Unlike rigid innerduct, the color of MaxCell is not related to primary use. Recommendation: In multi-pack installations, using various color allows for easy identification from either end of an installation. Colored Tracing Thread Colored coded pull tapes

7 MaxCell Basics MaxCell is available in four standard sizes - 4, 3, 2, and Micro 1.25 MaxCell comes in different configurations; 3-Cell, 2-Cell or 1-Cell. 4 cell is available in 3 size only, 3 x 4 cell. Each size can include an 18 gauge copper wire for traceability/detection. Six color of identifying thread are available (black, blue, red, green, white, yellow) Color-coded pull tapes are pre-installed (orange, blue, white) MaxCell is marked every 5 feet, the internal pull tapes are marked every foot MaxCell used for OSP applications is pre-lubricated Riser and Plenum MaxCell are available and are not lubricated Standard reel sizes from 250, 1,000, 2,650, 5,300 & 10,000 Custom sizes are available over 500 up to 10,000 in 5 foot increments

8 MaxCell Basics Detectable Easy to locate MaxCell can include an 18 gauge copper wire for locating.

10 Smaller Construction Footprint 3X More Pathway on 3X Smaller Reels Reels of MaxCell can fit through the front door of a building. Reel lengths can fit in the back of a truck or van. Multiple reels can fit on one reel trailer. Remaining inventory doesn t consume valuable storage space. MaxCell is nearly 90% smaller and lighter

12 Small Construction Footprint Pfluger Bridge over Lady Bird Lake Two reels set up and hand pulled by 1 person, 795 feet. No lanes of traffic had to be blocked off. Lamar at Riverside nor Cesar Chavez

13 Performance Advantages MaxCell Maintains Low Cable Pulling Tensions Coefficient of Friction of MaxCell is 30% lower than HDPE MaxCell does not possess reel memory; it will not spiral like HDPE inner duct MaxCell will not twist during installation when using swivels MaxCell will not creep or walk while installing cables MaxCell can be installed in conduits with many sweeps and bends MaxCell Protects the Cable and Conduit Pull Tape will NOT burn through MaxCell Melting Point of MaxCell = 485 F, while HDPE = 220 F Separates cables to prevent abrasion MaxCell is not Affected by Long Term Exposure to Common Ground Chemicals, Petrochemicals, Fresh or Salt Water

14 Performance Advantages National Electrical Contractors Association s (NECA) Manual of Labor Units (MLU) shows that MaxCell is dramatically more efficient than rigid innerduct. Average installation for MaxCell s most commonly used product 3-inch three-cell fabric innerduct under normal circumstances takes approximately 8 hours per thousand feet according to NECA. Installation time for traditional 1-inch rigid innerduct averages three hours per hundred feet the equivalent of 30 hours per thousand feet under normal circumstances according to the report. The report also found that, under what NECA defines as very difficult conditions, installation of MaxCell flexible innerduct is even more advantageous than traditional rigid innerduct.

15 Solutions from MaxCell

16 Overbuild Problems Existing outer ducts occupied with cables and/or rigid inner ducts Desire not to utilize last empty duct Microducts are difficult to place into occupied ducts Rigid innerducts may damage existing cables General Benefits Avoid new construction of additional outer duct/inner ducts Save remaining empty ducts in congested areas for future network additions/changes Decrease time required to startup network
