Why does Thailand have so many power lines?

WHY ARE THE CABLES IN THAILAND A MESS? Currently, telecommunications, broadband, and broadcasting companies rent the cement poles from the Provincial Electricity Authority (PEA) and the MEA. Then they add wires as each individual subscriber signs up.

What are the advantages of overhead transmission cables?

Advantages

• High Power transmission.
• Low installation and material cost.
• Long-distance transmissions.
• The fault or damage in overhead lines can easily locate.
• Maintenance of the line is easier.
• Extension or joining on overhead lines can be performed easily and also it facilitates easy replacing.

Which is better underground or overhead power cables?

Underground cables are safer to the public, animals and environment compared to the overhead lines i.e. there are no issues such as people getting in contact with fallen lines. The overhead cables can be brought down and human, animal intervention, weather as well vegetation such as trees.

Does Bangkok get power outages?

Power outages in Bangkok tend to be an almost regular occurrence; generator explosions, deafening booms which leave my cat hidden in the bathroom all day. Maybe we live in an unlucky area but it does seem to happen a lot, more than you’d expect from a swank central area of Bangkok.

How tall are phone lines?

The standard utility pole in the United States is about 40 ft (12 m) long and is buried about 6 ft (2 m) in the ground. However, poles can reach heights of 120 ft (37 m) or more to satisfy clearance requirements.

Why are electricity cables above ground?

Cables are typically installed 1m below ground, whereas the conductors of an overhead line are typically more than 10m above ground, so the magnetic field directly above such a cable is usually higher than that directly below the equivalent overhead line.

What are the disadvantages of overhead transmission cables?

Disadvantages of overhead transmission lines:

• Higher maintenance cost.
• Less safety for humans.
• More faults/accidents/failures.
• Bad visual appearance.
• More voltage drop.
• Cause interference with neighboring communication systems.
• The chances of being hit by lightning are high.

What are the disadvantages of overhead lines?

Following are the disadvantages of Overhead Transmission: ➨These lines visually pollute the areas where they are installed. ➨These lines suffer from problems such as terrorism, vandalism and lightning etc. ➨Sometimes these lines come in the way of birds and low flying aircrafts or drones which can be dangerous.

Why is underground cable more expensive?

Undergrounding is more expensive, since the cost of burying cables at transmission voltages is several times greater than overhead power lines, and the life-cycle cost of an underground power cable is two to four times the cost of an overhead power line.

Why do we employ underground cables really compared to overhead lines?

Compared to overhead lines, the underground cables have the following advantages : It ensures non-interrupted continuity of supply. The possible supply interruptions due to lightening, storms and other weather conditions are eliminated because of underground cables. It requires less maintenance.
