Overhead cables are installed above the ground on poles or towers and are generally easier to access for maintenance but more exposed to weather conditions, while underground cables are buried beneath the ground, offering better protection from environmental factors but requiring more complex and costly installation and repair processes. Vazpo sells a wide range of cables including overhead and underground cables.(www. vazpocable. com)

What is underground power transmission?
power cables under ground rather then overhead.
What happens to the ground when there is a thundercloud overhead?
When a thundercloud is overhead, the intense electric fields generated can induce a positive charge on the ground below. This in turn can result in the ground becoming positively charged, leading to a potential difference between the cloud and the ground. If the potential difference becomes large enough, it can result in a lightning discharge.
Why are the cables of the national grid are above the ground and not buried underground?
undergroud cables would be: -much more expensive -much more difficult to repair -difficult to bury where they cross canals, rivers and roads. also, overhead cables are high above the ground, underground cables could affect people more because the cales wouldn't be very deep
What are the differences between UF-B and NM-B cables, and which one is more suitable for outdoor installations?
The main difference between UF-B and NM-B cables is that UF-B cables are designed for outdoor use and can be buried directly in the ground, while NM-B cables are meant for indoor installations and cannot be exposed to moisture. Therefore, UF-B cables are more suitable for outdoor installations due to their weather-resistant properties.
What is the purpose of ground wires in overhead transmission lines?
connection of the ground of all the transmission lines and used as a communication cable between protection devices
What is difference between original ground level and normal ground level?

What is the difference between ground espresso and ground coffee?
The main difference between ground espresso and ground coffee is the fineness of the grind. Ground espresso is much finer than regular ground coffee, which results in a stronger and more concentrated flavor when brewed.
Why are the insulation resistance values higher for test between phase than between phase and ground?
When testing two cables there is twice the the amount of insulation, as opposed to one cable to ground.
What is the difference between Stolon and Rhizoid?
rhizoids are below-ground, stolons are above-ground
What is the difference between airspeed and ground speed?

What are the differences between the 12-2 and 12-3 electrical wiring cables?
The main difference between 12-2 and 12-3 electrical wiring cables is the number of conductors they contain. 12-2 cable has two conductors (black and white) and a ground wire, while 12-3 cable has three conductors (black, red, and white) and a ground wire. The additional conductor in 12-3 cable allows for more complex electrical circuits to be created.
What is the difference between overhead transmission line and under ground transmission line?
Um. One is hung above your head on telephone poles and the other is ran underground in conduit? Unless you meant something else? Also burying cable costs ~10 times as much for transmission lines as overhead. It also usually has a lower power carrying capability, since it cannot dissipate heat as readily as an overhead conductor.
