Why are utility cables and pipes buried underground?
The underground cables service is the replacement of overhead cables work that supplies electricity or telecommunications with underground cables. This is usually done to prevent fires and make lines less vulnerable to blackouts in stormy weather, heavy snow or ice. One of the additional advantages of the undergrounding, according to Geotechnical Services, is the artistic tone of the landscape without the powerlines. Underground installation can increase the primary cost of power distribution and transmission of electricity, but it can also reduce operating costs over the life of the cable.
Here are some of the great reason why utility cables and pipes buried underground?
Public protection: – The underground operation method is trustworthy than the overhead system since all distribution cables are buried underground and probably will not pose to any danger.
Flexibility: – The overhead operation method is very flexible than the underground operation method. In the recent case, duct lines, manholes, etc., are constantly fixed once installed, and the mass development can be accomplished by laying new lines. However, on the overhead operation method, wires, poles, transformers, etc. are easily moved to adapt to changing mass conditions.
Less voltage drop: – Underground electric cables are created in a form to decrease energy losses, so the voltage drop in underground power cables is considerably lower than that in overhead distribution and transmission lines.
Appearance: – Generally the appearance of the underground operating method is helpful because all division lines are invisible. This factor puts considerable pressure on utilities to move to the underground operation system.
Prone to Environmental Hazards: – One of the great disadvantages of using the overhead power line is because it is exposed to environmental hazards. The risk of faults in underground methods is very limited because cables are run underground and are generally better isolated. When thunder or lightning transpire on the overhead lines, they are more likely to damage them. But for an underground system method, the tendency to sustain damage due to environmental hazards is considerably lower.
Less space: – Overhead power line occupies a lot of space. In densely populated areas, space is the utmost premium – and you won’t want to use it on cables that could be fixed underground. Apart from the point that underground cables are out of eyesight, they also claim a narrower area of land than overhead cables.
Useful life: – The beneficial life of the underground method is very higher than the overhead method. The underground method can last for over 50 years while the overhead method can last for 25 years.
Less Fault Occurrence: – As it is well covered with several insulating layers with mechanical protection, there is less chance for interference to occur in electrical fault situations.
Using the latest technologies and methods such as ground-penetrating radar systems (GPRS) and the electromagnetic detectors, radio detection; it is very possible to accurately locate a wide range of underground utilities, including pipes and cables, metallic and non-metal. These utilities can then be mapped using a combination of traditional survey, GPS and Geographic Information System (GIS) techniques.
