Question: What is Detectable MULETAPE?
Answer:
Designed to meet the same stringent requirements as NEPTCO's MULETAPE, Detectable MULETAPE is a low stretch, high strength woven tape containing a corrosion-resistant, metallic conductor. The conductor's extrusion-friendly jacket is rated to withstand the typical innerduct extrusion process, and is resistant to moisture.
Detectable MULETAPE is available in tensile strengths of 900 through 6,000 lbs., and is uniquely packaged on sturdy wooden reels. It is available in lengths of 3,000 to 25,000 feet. Customized lengths and strengths are available upon request.

Question: How should I ground Detectable MULETAPE in an urban location (in manholes)?
Answer:
Ground detectable tape to the hole's bonding hardware. If needed, drive a 4-foot long section of 1/2" rebar ground rod into the floor approximately 3'6" deep. Attach a ground clamp with termination nut to the ground rod.
Strip insulation from the jacket of the Detectable MULETAPE wire, attach to the ground lug, and secure with a locking nut.
Bring a small coil of Detectable MULETAPE to the highest point in the hole to avoid having to enter the hold later, and attach a transmitter for locating.

Question: How should I ground Detectable MULETAPE?
Answer:
Drive a 4-foot long section of 1/2" rebar ground rod at the hand hole marker post approximately 3'6" deep. Attach a ground clamp with termination nut to the ground rod.
Strip insulation from the jacket of the Detectable MULETAPE wire, attach to the ground lug, and secure with a locking nut.
Label the marker post with a green dot sticker to indicate a "grounded" location.

Question: Once the cable has been installed, the MULETAPE is no longer in the duct. How can it then be useful in locating conduit?
Answer:
Most firms install multiple ducts side-by-side in a trench in an attempt to "future proof" their project. In some cases the additional ducts may lie empty for several years until the need for new lines arises. When the time comes to install the lines, the crew can easily find the ducts by locating the detectable tape still lying in the conduit.

Question: What frequency should I use when searching for buried conduit?
Answer:
Most locating systems provide crews with a choice of frequencies, enabling them to customize the unit for specific local field needs. With Detectable MULETAPE, there is no concern over the ability of the tape to function in a wide range of frequencies. Crews can simply choose the appropriate frequency for the type of underground plant in question. Whether it's long-length, low frequency detection, or precision locating in congested cable plants at high frequency, the reliability of Detectable MULETAPE has been proven over and over again.

Question: What procedures should I use when grounding Detectable MULETAPE in a rural location?
Answer:
Take the MULETAPE out of the hole and bury it 8" deep to the marker post (this will eliminate the need to dig up the holes every time a locate is necessary.) Drive a 4-foot long section of 1/2" rebar ground rod at the hand hole marker post approximately 3'6" deep. Attach a ground clamp with termination nut to the ground rod.
Strip insulation from the jacket of the Detectable MULETAPE wire, attach to the ground lug, and secure with a locking nut.
Bury a small coil of the detectable tape at the post, since extra slack will prevent wire breakage. Label the marker post with a green dot sticker to indicate a "grounded" location.
Footage markings on the tape help the crew determine approximately where they should start digging to locate the faulty coupling.

Question: Why should I use MULETAPE?
Answer:
NEPTCO's line of cable pulling tapes, known as MULETAPE, has been setting the industry standard for over 15 years. MULETAPE is so reliable and its performance is so consistent that Bellcore Labs used it as a model for its regulated-market specifications. NEPTCO’s MULETAPE is lightweight, easily blown through conduit, reusable, durably printed with sequential footage or metric markings and available in a variety of constructions such as woven jacketed, aramid and polyester.

Question: What's wrong with using rope to install fiber optic cable?
Answer:
It's a simple law of friction - polyrope can burn right through innerduct in a matter of seconds. Once rope damages the duct, cable is likely to get caught in the damaged plastic. If that happens, the crew will have to dig it up for repair or replacement. Or worse, they may just apply more tension to the rope and try to yank the cable free. If that happens, the real damage may not be discovered until the end user complains.
Even if the cable doesn't get caught, odds are it will snag on the frayed plastic. With each pull of the polyrope, the jagged edges of the damaged duct will gnaw at the cable, stripping the jacket, damaging the cable core, and applying excessive tension to the fibers. Pulling with polyrope causes the fragile fiber tubes to crush under excessive tension, making the cable susceptible to micro bending and failure.
Once the rope burns through the duct, it may also pose a threat to adjacent live cable. A fiber optic cable designed to provide 25-30 years of service, may fail in as little as 5 years when installed with polyrope. For a more comprehensive explanation of burn-through, please click here.

Question: How should MULETAPE or Detectable MULETAPE be installed?
Answer:
Pulling tape can be installed in a couple of ways. In some instances, the conduit manufacturer will extrude the tape right into the duct at the factory (known as pre-threaded duct). It can also be "blown through" duct that is already buried, using a blower and innerduct projectile.

Question: How can MULETAPE help verify the continuity of installed duct?
Answer:
Conduit is installed in lengths that are joined together by couplings. If the couplings break, or are blown out when the conduit is pressurized to blow the tape through, the tape will not reach the far end of the conduit
