Power transmission
Long distance transmission of electric power is one of the major challenges of the electrical age the goals which engineers have been working towards have remained the same despite many other things changing over the years.
1- Efficiency – transport electric power over distance with minimal loses.
2- Safety – transport power through ubanand rural areas mini missing harm to people and animals.
3- Cost – use minimal raw materials and builoings operating costs people.
4- Roboustness – create a system which is not vulnerable to surges from lightining , solar flares , earth quakes , icestorms wind storms , and have the system able to heat it self when ovtages occur isolating problem areas.
There are four ways to transport electrical power over long distance :
High voltage alternating current
High voltage Ac power :
Alternating current proved to be the most effective for distance transmission because of several great properties.
1-Ac current can be easily converted fron low voltage to high voltage and back again . higher voltages are beast for pushing power through conductors , because higher voltages lose less energy along the trip than lower voltages.
2- ac power is good for power grids as it distribuits it self throughout a grid and can heat by routing power around an outage area.
Ac power is the most common method of power transmission in the world , lines , are suspended high above the ground as they produce an electromagnetic field around the wire . the higher the voltage , the larger the electromagnetic filed generated around the wire.
But the negative point of ac transmission by lines is it significant losses from induction.
This system of transmission is constantly approued by engneers.
The bargh ara company is specilised for transmitting the electricity power through the lines.
Power generation
A characteristic of electricity is that it is not a primary freely present in the nature in remarkable amounts and is most be produced.
Production is called out in power stations ( also called power plant ) electricity is most often generated ata power plant by electromechanical generators , primary driven by heat engines , fueled by combustion of oil fules nuclear fission following water wind solar and geothermal power.

Pipelines and tank farms
Bargh ara,s Oil, Gas and Petrochemicals Division was established in 2017. After organizing a flexible and robust structure suitable for this industry and forming a team of elite managers, engineers and technicians who have had great experience in oil and gas projects and combining them with bright, young and super active engineers, barghara was able to conduct some of the biggest national projects in Iran such as a few of the national gas pipeline projects.
After those successful experiences, this division has proved itself as one of the leaders in managing contract, site supervision, design and engineering services providers in Iran's oil and gas industry and has recently entered into the EPC project markets.
All these achievements are mainly based on bargh ara,s extreme emphasis on quality improvement of its services and customer satisfaction.
