Cable pulling, Jointing and Termination equipment play very important rules to ensure a quality work to operate safe and long-life operation. Cable pulling tools make to 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 measurement will not same for all, depending the voltage rating, cable size, laying location and others vicinity factors cable ducts or trenches depth and width varies.
According to low, medium and high voltage cable, the open trench depth and width are varies. Usually the higher the voltage range the higher the depth and width of cable trench.
At the bending point, the cable trench must be followed adequate size as per cable manufacturer recommendation, means trench width must be sufficient to bend the cable without overexcite mechanical stress to cable. The cable bending diameter depends on cable flexibility, and cable flexibility depends on cable constructed materials. Corrugated aluminum metallic sheath is used to get more flexibility for high and extra –high voltage cable.
Cable trench should be sufficient to movement 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 trench with brief description are as below:
- Cable Winch
- Winch Wire Rope
- Cable Pulling Swivel
- Cable Socks
- Cable Rollers
- Corner Rollers
- Draw Off Rollers
- Cable Drum Trailer
Cable Winch– A cable winch is a mechanical device that is used to pull in (up) the cable or let out the cable or to adjust the cable pulling tension. It consists of a spool and attached hand crank.
During cable the cable winch is placed the end of the cable trench that provides smooth and controlled actual pulling of the cables through the trench. There are various cable winches depending 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 helix formatting a composite rope. Larger diameter winch rope consists of multiple number of wire strands to provide larger pulling strength.
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 Swivel–The cable pulling swivel is a connecting device that connect between the grip (cable) and the pulling rope or winch wire. The cable pulling swivel is designed 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 damages.
The impertinency to select the cable pulling swivel is to mind the maximum pulling capacity at or above the pulling-force of the cable puller.
Depending the cable types and pulling purposes swivel or connector may different types, like- Clevis pin, Line swivels, Rope connectors, Breakaway swivel and connectors, shackle and connectors, Wire rope bridle slings, etc.
Cable Socks–Cable pulling sock is a such kind of cable installation tools that high tensile galvanized steel wire shock than ensure an efficient method of supporting for cable pulling.
Cable socks are also called as cable grips or cable shocking. This is the most handy efficient tools 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– Cable roller is simple cable pulling tools that 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. Cable easily moves on it without any scratch on it and cable puller feel less weight on it. Cable roller mainly two types according its using location.
- Straight Line Cable Rollers
- Corner Cable Rollers
- Draw Off Rollers
The straight line cable rollers are used at straight part of the cable trench. Normally 3m to 4m apart it be used, also consider the cable weight and diameter. Straight cable rollers protect the cable to touch the bottom and soil surface that may cause scratch 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 a vertical and horizontal cable roller to allow cable pulling safely without any damages. Actually corner roller protect cable from extra stress on cable outer jacket due trench bending.
Draw Off Roller is one kind of cable pulling roller which is used near the cable drum during cable pulled off from drum to trench. It is used to direct or guide the cable to the trench in straight line.
Cable Drum Trailer- The cable drum trailers sense to transport the cable drum from one place to another in site, on the other hand cable trailer is also mean to stabilize the cable drum while the cable is being pulled through the cable trench or cable ducts. Cable drum trailer using to stabilize the drum during cable pulling is commonly used as Cable Jacks.
