In today's modern world, electricity plays a vital role in human life. From the lighting of houses and streets to 
the energy supply of industries and factories, everyone depends on this vital element. To transmit electricity over
 long distances, extensive networks of electrical wires are used.

Among the different types of electric wires, the air hard wire has a special place. This type
 of wire, due to its unique characteristics, is known as the lifeblood of electrical networks.

In fact, aerial hard wire is a type of electrical wire that is used to transmit electric current 
in the open air, especially over long distances. These wires consist of metal conductors such as
 copper or aluminum that are covered with thick insulation. The insulation used in air hard wires
 is made of high-quality materials and is responsible for protecting the conductor from 
atmospheric and moisture factors.

Why are hard air wires used?
The use of aerial hard wire in electrical networks brings many advantages,
 some of which we will mention below.
High resistance: due to the use of metal conductors and thick insulation, air hard wires
 have a high resistance to various weather conditions such as wind, rain, snow and frost.  
This feature makes them ideal for use in difficult and mountainous areas.

High capacity: Due to its large diameter and high-quality metal conductors, air-hard wires 
can carry high-ampere electric current.  This feature makes them suitable for use in high
 voltage power transmission lines.

Features and benefits of air hard wire

As mentioned in the previous section, air hard wire has a high resistance to different weather 
conditions due to the use of metal conductors and thick insulation. For this reason,
 these wires are considered an ideal option for use in difficult and mountainous areas.

Resistance to wind and storms: One of the most important advantages of aerial hard wires
 is their resistance to wind and storms. The metal conductors and thick insulation of
 these wires make them resistant to strong winds and violent storms. This feature prevents
 power outages in adverse weather conditions and increases the stability of power networks.
Ideal insulation: The insulation used in air hard wires is made of high-quality and waterproof
 materials such as PVC, polyethylene or rubber. These insulators completely protect the metal 
conductors from moisture, rain, snow and frost. Proper insulation of aerial hard wires prevents
 electric current leakage and electrocution in wet conditions and increases the safety of electrical networks.

Long service life: Due to the use of high-quality materials in the manufacture of hard air wires,
 these cables have a long service life. These wires can be used continuously for decades without 
needing to be replaced or repaired. The long life of rigid air wires makes them an economical
 and cost-effective investment.

Easy installation: Air tight wires are easy to install due to their simple structure and light weight.
 These wires can be installed at a suitable height using electric poles, masts or various bases. 
Easy installation of aerial hard wires accelerates the process of construction and repair of power
 transmission lines and reduces related costs.
Other advantages of air-tight wire: In addition to the advantages mentioned above, air-tight wires
 have other advantages, including:
Significant capacity: these wires can carry high amperage electric current.
Resistance to chemicals: These wires are resistant to chemicals and acids.
Compatibility with the environment: these wires are made of recyclable materials and cause minimal
 damage to the environment.
