When using the direct laying strategy, the process includes burrowing channels underground and implanting the wiring inside layers of sand. This is the cheapest approach to lay underground cables, and only underground electricians are qualified to carry out this job effectively. The draw-in method is more expensive than direct laying, however future repair costs may be reduced. These cables are made up of iron, coated stone, or cement. They are then furnished with asphalts for access, making them the most reasonable strategy for metropolitan zones.
In the solid system method, the wiring is set and covered trenches like the indirect method. The difference is that shielded wiring from mechanical components through open pipes or troughs. A solid system is no longer commonly utilized because it is labour-intensive and less practical than the other methods.
Important Pointers for Underground Cable Installation
Never Carry or Drag the Cables Over Uneven Surfaces
Carrying the cables over the shoulders or dragging them on the ground could push the lines beyond their minimum bending radius. This could result in ruptured cables and insulation, in which case, the lines become faulty even before utilized.
The minimum bending radius is measured based on the external diameter of the cable. Only a professional underground electrician will know what to do.
Be Wary of Temperature Drops
Cables are susceptible to environmental factors. When the temperature outside drops, the wiring becomes brittle and prone to damage. In emergency or urgent cases, experienced underground electricians commonly warm the cables using heater fans to retain cable integrity while working under extreme conditions.
Do Not Skimp on The Proper Equipment
Poorly laid out systems result in more faults and higher maintenance, so it’s vital to get things right the first time. Mechanical devices like winches, cable drums, angular idlers, and cable stampers lessen the margin of error during installation. These also hasten the work pace and ease the grunt work for the team on site.
Proper installation of underground cables has a substantial impact on the serviceable life of a utility system, whether simple or complex. Understanding the process and implementing precautions can be guaranteed a longer useful life and less taxing upkeep for your underground channels.
