cable hauling ropes sydney

Everyone will face some difficult situations during cable pulling. In that scenario, some unorthodox and creative pulling method will solve the issue. Even this can be done using a different instrument. For a successful pulling, the puller must do some steps before starting the cable pulling process. You must also check the quality of the cable before feeding it will help to ensure the safety of the job. 

Some of the other factors to be considered before starting the cable pulling process are size and types of raceways, conductor, cable hauling rope, reels, cable spools, cable splice, the entrance of raceway cable, approved lubrication that can be used for cable pull, tools used for cable pulling. For installing cable with the large diameter you need to use cable reel arbor and jack stands.

In this article let us discuss some factors that are to be considered before starting cable pilling and ways to use cable hauling rope appropriately.

  • Temperature:

Each insulation conductor has a different temperature range for safe installation and operation. But mostly cable pulls are performed both in a warm climate and cold climate for electrical construction work. Most of us think that cable pull must be done only when it is stored in a cold environment but this is not actually true.

In the scenario, the insulator will be in brittle condition like many rubber material and thermoplastic material. The material will crack or split in this situation. This will happen even with minimal tension or bend. In the long run damaged insulation is similar to no insulation.

  • Moisture:

The quality of the cable is affected by the moisture content. The effect of damage will be more when compared with the other damages. Both the vapor state and liquid state of the moisture is very important. Cables like medium voltage and power cable, coaxial cable, shielded cable can absorb moisture for a long time. Capacitive characters and insulation of the cable are affected by the different levels of moisture. All types of electrical cables are negatively affected by capillary action.

All types of cables must be sealed at their ends. Try to follow approved methods for sealing the cable. In most cases, you can use plastic and rubber insulation tape for sealing the cable but for a few cables, you must purchase a sealing kit. In this method, the heat shrink device will be placed at the end of the cable which helps to protect the cable from moisture. 

  • Calculations:

To calculate the tension of cable pulling most industries use the same friction constant and common formula. Some of the variables used in the calculation formula are friction coefficient, individual bend radius, total bend degree, raceway type, length of the raceway and gravity.

For successful cable hauling rope installation, you need an electrician and other contractors. Some of the specifications designed during the project are the maximum bends that can be allowed for raceway and lubricants which can be used for the pulling process. During the installation process, you must follow all the requirements and building codes. Before starting the installation process you must check all the specifications that must be followed during the process.
