Cable Pulling & Jointing Tools and Equipment

Cable pulling, Jointing, and Termination equipment play very important roles to ensure quality work to operate a safe and long-life operation. Cable pulling tools make for easy and safe cable laying, less cable sheath or screen damage/scarce, applying pulling tension correctly, and spacing cable in trench or duct properly. Cable Joint and Termination tools are very much special for cable jointing and cable sealing end termination.

How Use Cable Pulling Tools & Prepare Cable Trench?

Before laying cable, cable trench or cable duct must prepare as per site requirement. Cable ducts or trench measurements will not same for all, depending on the voltage rating, cable size, laying location, and other vicinity factors cable ducts or trenches' depth and width vary.
According to low, medium, and high voltage cables, the open trench depth and width vary. Usually the higher the voltage range the higher the depth and width of the cable trench.

At the bending point, the cable trench must be followed an adequate size as per the cable manufacturer's recommendation, which means the trench width must be sufficient to bend the cable without overexciting mechanical stress to the cable. The cable bending diameter depends on cable flexibility, and cable flexibility depends on cable-constructed materials.  The corrugated aluminum metallic sheath is used to get more flexibility for high and extra–high voltage cables.

The cable trench should be sufficient to move the installer to install the cables and allow the cables to be installed within specified cable pulling dimensions and without damaging the cable sheaths considering bending radii.

Equipment Required For  Cable Laying In Trench 


Key equipment for cable laying in the trench with a brief description is as below:
  1. Cable Winch
  2. Winch Wire Rope
  3. Cable Pulling Swivel
  4. Cable Socks
  5. Cable Rollers
  6. Corner Rollers
  7. Draw Off Rollers
  8. Cable Drum Trailer

Cable Pulling WinchCable Winch– A cable winch is a mechanical device that is used to pull in (up) the cable or let out the cable or adjust the cable pulling tension. It consists of a spool and an attached hand crank.

During cable, the cable winch is placed at the end of the cable trench which provides smooth and controlled actual pulling of the cables through the trench. There are various cable winches depending on the types of cable to pull, like- telecommunications, heavy power cables, and lightweight small power cabling, etc.

Winch Wire Rope– Winch wire rope is nothing but a metal wire rope twisted into a helix formatting a composite rope. Larger diameter winch rope consists of multiple number of wire strands to provide larger pulling strength.
Winch Wire Rope

During cable pulling in a cable trench, the winch wire rope is attached to the cable end eye bolt to be pulled through the winch rope.  This winch wire rope allows for heavier cables to pull through the trench and gives extra strength.

Cable Pulling SwivelCable Pulling Swivel–The cable pulling swivel is a connecting device that connects the grip (cable) and the pulling rope or winch wire. The cable pulling swivel is designed in such a way that used to allow the winch wire to rotate when being pulled and avoid kinking or twisting the cable core and protect from damage.

The impertinence to selecting the cable pulling swivel is to mind the maximum pulling capacity at or above the pulling force of the cable puller.

Depending on the cable types and pulling purposes swivels or connectors may be different types, like- Clevis pins, Line swivels, Rope connectors, Breakaway swivels and connectors,  shackle and connectors, Wire rope bridle slings, etc.

Cable Pulling Shocks
Cable Socks–A cable pulling sock is a kind of cable installation tool that high tensile galvanized steel wire shock that ensures an efficient method of supporting for cable pulling.

Cable socks are also called cable grips or cable shocking. This is the most handy and efficient tool to pull the cable in trenches, ducts, or buildings. This is high tensile galvanized steel wire, also available in stainless steel or Kevlar constructed.

Cable Roller– A cable roller is a simple cable-pulling tool that is used to roll or pull the cable on it. It is placed 3 to 4 m apart and at corners to allow for the bending radius of the cable. The cable easily moves on it without any scratch on it and the cable puller feels less weight on it. The cable roller is mainly two types according to its using location.
    1. Straight Line Cable Rollers
    2. Corner Cable Rollers 
    3. Draw Off Rollers
Straigth Cable RollerCorner Cable Roller
The straight-line cable rollers are used at the straight part of the cable trench. Normally 3m to 4m apart be used, also consider the cable weight and diameter. Straight cable rollers protect the cable to touch the bottom and soil surface which may cause scratches on cable outer jacket. 

Corner Rollers are to be used within the cable trench where there is a bend in the cable trench. Actually, corner cable rollers are incorporated vertical and horizontal cable rollers to allow cable pulling safely without any damage. Actually, the corner roller protects the cable from extra stress on the cable outer jacket due to trench bending.

Draw Off Roller is one kind of cable-pulling roller that is used near the cable drum during cable is pulled off from the drum to the trench. It is used to direct or guide the cable to the trench in a straight line.

 Cable Drum Trailer- The cable drum trailers sense to transport the cable drum from one place to another on-site, on the other hand, a cable trailer is also meant to stabilize the cable drum while the cable is being pulled through the cable trench or cable ducts. A cable drum trailer used to stabilize the drum during cable pulling is commonly used as a Cable jack.

Cable Jointing Tools & Equipment

To prepare the cable to join each other or for the cable sealing end, many special tools and equipment are necessary for a cable jointer. It also varies from types of cable and types of jointing accessories. A very common tools list is to be used for cable jointing and termination works.
