What are the hazard in cable pulling?
Manual Handling, Falls of persons from heights, Contact with live electrical conductors, Slips trips and falls. Injuries to plant, cable twisting and jamming Blocked access egress routes.
What is another name for cable puller?
A cable puller, aka cable tugger, is used to pull cable through a conduit.
How is wire pulled through conduit?
Pulling Wire With a Fish Tape
- Feed End of Tape Into Conduit. Feed the end of the tape, which has a hook on it, into the same end of the conduit that you will pull from.
- Push Tape Through Conduit.
- Strip Insulation.
- Hold Wires Together.
- Bend Wire and Loop Through Fish Tape.
- Wrap Fish Tape Hook.
- Apply Lubricant.
What’s the difference between MC and AC cable?
The main difference between the AC wire and the MC wire is that the metal-clad cable has a standard ground wire, whereas the AC cable relies on a jacket in combination with a wire or thin strip to secure the grounding. The metal armor can also act as a part of the earth grounding in combination with the bonding wire.
How do you pull a cable through a pipe?
1. String Method
- Tie the string: Tie a strong string to a long, inflexible rod.
- Push the rod: Push the rod through the conduit, tied end first.
- Attach the wire: Tie the electrical wires to the string.
- Pull the wire: Pull the rod and string through the conduit, pulling the wire along with them.
What is ITC cable?
NWI’s ITC or Instrumentation Tray Cable is engineered to meet or exceed application requirements for factory floor automation equipment, material handling, sensors and transducers, process controls and other applications.
How do you calculate tension in cable pull?
P = Tb / r (Formula 6) = actual sidewall pressure on cable, lbs./ft. Tb = pulling tension at and of bend, lbs. The maximum allowable pulling tension at bend (Tbm) is the limit that the calculated pulling tension (Tb) should be compared.
What is DC cable?
The DC wire is used in places where self-generation of power takes place like solar panel or batteries. The DC wires are mostly double insulated because it is mostly used for outdoor applications. The current carrying capability of DC cable is better than the AC cable.
