Why over head lines are used in Extra high voltage AC lines?

Overhead lines are used in extra high voltage (EHV) AC transmission primarily due to their cost-effectiveness and ease of installation compared to underground cables. They allow for efficient transmission of electricity over long distances with minimal energy losses, as the air acts as an insulator and facilitates heat dissipation. Additionally, maintenance and fault detection are more straightforward with overhead lines. Overall, these factors make overhead lines a preferred choice for EHV AC systems.


How cold should be copper lines on ac unit?

There is no real set temp for the lines ,the bigger thing is the heat that the outside unit is producing when the unit is on. A normal functional AC unit will be around 105 to 110 degrees as for the copper lines they should feel pretty cold to the touch like an ice colds beer feels in your hand......


Why are transmission voltages in ac systems generally higher than those in dc systems?

The main advantage of using ac is that you can step up and step down the voltage by means of a transformer,since transformer works only with ac. another thing is that if dc power is used for transmission,then the power loss associated with t will demand the use of transmission lines which are very thick(have a larger cross section)..for long distance transmission this may lead to the requirement of power lines with impractical dimensions.


Why is discharge line leaving outside unit cold on central ac?

The expansion device inside the outside unit expands the refrigerant gas and as a result, the discharge lines chills


What is a vacume pump for an ac?

A vacuum pump for an air conditioning (AC) system is a device used to remove moisture and air from the refrigerant lines before the system is charged with refrigerant. This process is essential to ensure efficient operation, prevent contamination, and avoid potential damage to the compressor. By creating a vacuum, the pump helps eliminate any trapped air and moisture, ensuring the AC system can operate at peak performance. Proper vacuuming is a critical step in AC installation and maintenance.

How can condensation on AC lines be prevented or managed effectively?

Condensation on AC lines can be prevented or managed effectively by properly insulating the lines to reduce temperature differences, ensuring proper ventilation and airflow around the lines, and maintaining the AC system regularly to prevent any leaks or issues that could lead to excess moisture buildup.

How do you change the ac lines on a 1998 Trans am?

To change the AC lines on a 1998 Trans Am, first, ensure the system is fully discharged by a professional to avoid refrigerant exposure. Disconnect the battery, then remove any components obstructing access to the AC lines, such as the air intake or radiator. Use appropriate tools to unbolt and disconnect the old lines, then install the new lines, ensuring all seals are in place. Finally, recharge the AC system with refrigerant and test for leaks.
