they are made of alluminium
Why are wires hung loosely in summer?
beacuse is good
Advantages and disadvantages of underground and overhead cables?
Overhead transmission lines are less expensive, in most cases, significantly less expensive, than underground cables. Underground transmission cables require insulation, cooling systems, and -the most expensive feature- excavation!
What is the definition of suspension bridge?
A bridge with overhead cables to support it.
What is underground power transmission?
power cables under ground rather then overhead.
Are component video cables made of gold?
Compoent video cables themselves aren't made of gold, but they can be gold plated. Gold plated connectors allow for better conductivity. The cables are typically made of oxygen free copper.
Why are overhead electricity cables never tightly over a pylon?
Overhead electricity cables are not tightly strung over a pylon to account for factors like temperature changes, wind-induced movements, and maintenance needs. Having some slack in the cables helps to reduce stress on the wires and prevent damage or breakage.
What are VGA cables primarily used for?
VGA cables are cables which are used with computer electronics. The cables are primarily used to connect the monitor to the computer. Some of these cables are made for specific monitors or devices.
Why overhead lines are far cheaper than underground cables for long distances and less economical for short distances?
First of all, the overhead lines are cheaper because they are bare, while underground cables are armoured and insulated, hence explaining the higher price. Overhead cables come of course with accessories like poles and insulators (mostly porcelain). For shorter distance, underground cables are preferred as the cost of pole erection does not exist.It's also worth pointing out that the cost of excavating a trench is more expensive than erecting an overhead line, and this cost escalates dramatically with higher voltage systems. For example, a 132-kV double-circuit underground line is between 5 and 8 times the cost of an overhead tower line, whereas an 11-kV single-circuit underground line is up to twice the cost of a wooden-pole overhead line.
Difference between overhead cables and under ground cables?
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 are pylons used for?
Pylons are structures used to support overhead power lines or telecommunication cables. They provide a stable and elevated platform for these utilities to be transmitted over long distances. Pylons are typically made of steel or concrete to withstand environmental factors and ensure the safety of the cables they support.
Why is lead used in high voltage cables?
Steel-reinforced aluminium cables are used for overhead lines because aluminium is much lighter than a copper conductor, despite not being quite as good a conductor as copper. The function of the steel reinforcement is to improve the tensile strength of the conductor.
