Use the lubricant more heavily at the beginning of the pull and less so toward the end of the pull, as the interior of the conduit will become coated along its length as you pull. Follow the manufacturer's instructions for proper application. Watch Now: How to Pull Electrical Wire or Cable Through a Conduit Materials Pull string Lubricant (optional) Electrical tape Pulling Wire With a Mouse A conduit mouse, also called a conduit piston, is a small cylinder of foam that is slightly smaller than the interior diameter of the conduit. You use it with a shop vacuum. Tie Pull String to Wire Tie a strong string, called a pull string, to the loop on the wire running through the mouse. Insert Mouse Into Conduit Insert the mouse into the conduit on the end that is opposite to the end you will pull from. The mouse goes in first, followed by the string. Fit Shop Vac Hose Over Conduit Fit the hose of a shop vac over the other end of the conduit, and turn on the vacuum until the mouse is sucked all the way to that end, then turn off the vacuum.

Work Your Cables through Any Tough Space with the Right Equipment The biggest headaches when pulling cables comes when you encounter tight spaces, snags, sharp turns, and other places that regular human-size arms just cannot fit into! Without tools, you'd have to cause considerable damage to your walls in order to access all the cables you need to. That's where our selection of tools comes into play. Starting with the essentials, having the right pulling tape is a must-have for measuring or pulling cables within ducts. We have a variety of different kinds, but one particular pulling tape is made for copper and fiber optic cables and can resist up to 2500lbs of pulling. It's perfect for serious jobs like commercial, industrial, and utilities applications. In addition to helping to move your cables, it is clearly marked in feet for easy use, and can be used for jobs up to 3000 feet under or above ground! If you want to save the amount of labor you have to do, our Laserline cable installation tool allows you to quickly create a cable path by accurately launching pull line up to 120ft.
During the video you will observe the high voltage cable being taken up in sections. At the other end of the cable pull a Greenlee Ultra Tugger set up is located, the average for this cable pull was 6 ft per second. The reason for the sporadic uptake was variable stretch and tension being placed on the cable pulling rope. The total length of the HV cable pull was 1270′. The utility learned that with the ease at which the Southwire A-Frame trucks payoff that it was not necessary to have this large of a crew to handle the consolidation of cable into the trunk of the cable pull. Once set up this cable pull could have been performed with 4 crew members. Additional crew members were necessary and productive in initial manhole set-up, reel set-up and attending to manholes where the wire was being pulled straight through. Sealing Cable ducts Where electricity, pilot and telephone cables are installed into electricity cable ducts the utility engineering standard would normally recommend all cable ducts entering substations and buildings to be duct sealed to prevent the ingress of water and gas – this also applies to 33kV, 66kV and 132kV high voltage substation cables where cable transits are required.

The WCT's Best Compound Exercises E-Book Download this valuable FREE E-Book that goes over the best compound exercises for each body part (so that you stop wasting your time doing mediocre exercises) COMMON PULL-THROUGH MISTAKES BENDING AT THE SPINE Do not allow any motion to come from your spine. Focus on moving ONLY at the hips. Practice by standing 12 inches away from a wall, and try to make your butt come in contact with the wall. This can only be achieved through hip flexion FREQUENTLY ASKED QUESTIONS Can I Do Cable Pull-Through With A Band? Yes, the pull-through can be performed with a band. Just tie a resistance band to a sturdy structure and perform the exercise the same way as described above. The band will accommodate the resistance throughout the movement; i. e, there will be less stretch on the band at the bottom of the exercise, and more at the top. You can see a demonstration in our post – 20 Full Body Resistance Band Exercises. Try and get different sized bands, as they all provide different amounts of resistance.
If you've never pulled wire through conduit, it may seem a bit troubling. How in the world can you get the wire to push through conduit, especially when the conduit run may be hundreds of feet long? Unless the conduit is very short and/or perfectly straight, pushing it through is highly unlikely. And, of course, it won't just crawl through the pipe itself. Dry and bare wiring being pulled through conduit, especially PVC conduit, creates friction, making it even more difficult to pull the wire. There are a few basic tools and supplies that can help make pulling wire through conduit a snap. And it's always easier to pull wires with a partner. Pulling NM Cable Through Conduit Most wire that is installed in conduit is insulated wire (usually THHN or THWN) rather than sheathed cable, such as non-metallic (NM), or Romex, cable. Running NM cable inside conduit is not a standard practice and may not be allowed in all jurisdictions. The National Electrical Code (NEC) does not prohibit running NM cable inside conduit, but this installation is subject to conduit fill limits, just like insulated wire in conduit.

Of course, cable lubricants can be used as long as they do not harm the sheath material or the duct material – lubrication of the 11kV will reduce the co-efficient of friction of the cable pull between the 11kV cable sheath and inner cable duct wall. If we speak about 11kV triplex cables, you will get them only in smaller lengths because of the diameter – I suppose 350m on a perfectly straight line shouldn't be a problem. But please take into consideration the maximum pulling force, which is: 30N/mm2 of conductor cross-section for aluminium conductors and 50N/mm2 of conductor cross-section for copper conductors. Going above these forces can damage the 11kV cables and maximum cable pulling vary according to the specification of the medium/high voltage cable. Maximum Cable Pulling Tensions High Voltage Cables Up To 33kV Maximum permissible pulling tensions for each 11kV/33kV cable type are given below. These cable pulling tensions must not be exceeded under any circumstances. Efforts should always be made by the cable pulling teams to achieve lower figures by careful setting out of the work and positioning of the MV-HV cable drum.
