The price of building a trans-electric substation in Shiraz and the estimation of network implementation costs

Providing reliable, stable electricity in accordance with the standards of the electricity distribution company is one of the first and most vital steps for setting up any industrial, agricultural, manufacturing unit or large residential and commercial complexes. In Fars province and especially Shiraz metropolis, due to the expansion of industrial towns, gardens, agricultural water wells and construction projects, the demand for setting up medium pressure electrical facilities is increasing. In the meantime, knowing the price of the construction of the trans-electric substation in Shiraz and estimating the network implementation costs are very important in the financial planning of investors. Aerial distribution posts are considered the most popular option for medium capacities due to their high installation speed, economic efficiency and small space occupation. The engineering team of Bargh Kalat, as a reliable authority for the design, supply of equipment and implementation of medium pressure projects, with full knowledge of the technical regulations of the Shiraz Electricity Distribution Company, provides precise, optimal and economical solutions for the applicants.

The importance of building a trans-electric substation in the distribution network of Shiraz

The national electricity network in the primary lines usually transmits energy with a medium pressure voltage level (usually 20 kV). Electrical devices, industrial workshop equipment and agricultural water pumps require weak pressure voltage (400 or 230 V). Therefore, it is necessary to install a step-down transformer to change the voltage level. Electricity distribution stations are designed in both aerial and ground forms; But for common capacities up to 400 kVA, the aerial post is the most used. In Shiraz and its suburbs, such as the large industrial town of Shiraz, Siakh Darangun, Khan Zanyan and Dasht Arjan, the special climate of the region and the development of gardens and workshops have made the construction of an air station the most economical option. These posts are placed on concrete or telescopic bases and do not require the construction of expensive buildings, so they are very beneficial both in terms of implementation time and in terms of reducing the final price. With a brilliant history in this field, Kalat Electric Group is with you from the first stage of mapping to the connection to the Shiraz electricity grid.

The main components of air mail and its effect on the cost price

In order to correctly understand the price of the construction of the trans-electric substation in Shiraz and to estimate the costs of implementing the network, one must first know the equipment and technical components that make up it. Each part of this structure requires the provision of standard materials approved by the Ministry of Energy and the Shiraz Electricity Distribution Company. The distribution transformer is the heart of the substation, which is produced in different capacities such as 50, 100, 160, 250 and 400 kVA. Dubbed concrete foundations (usually 12 or 14 meter reinforced concrete foundations with appropriate tensile strength) form the foundation for the transformer, cutout fuses and arresters. Transformer platform, fuse cutout, lightning arresters and medium pressure insulators are other technical accessories. Low pressure distribution board, automatic switches, copper or aluminum communication cables, as well as the standard protection and neutral earthing system, are essential components of a standard air station. Kelat electrical experts minimize intermediary costs by directly supplying essentials from reliable factories and guarantee an irreplaceable quality.

Determining factors of the price of construction of electrical trans-station in Shiraz

The pricing of the construction of the air station is a function of many engineering and environmental variables, and it is not possible to provide a fixed figure without a field visit. The first and most influential factor is the rated power of the transformer; So that with the increase in capacity, dimensions, weight of the transformer and protection requirements will be bigger and the cost will increase. The geographical location and soil conditions of the project site in Shiraz are also decisive; The type of soil has a direct effect on the difficulty of excavation operations, digging an earth well and reaching the permissible ground resistance (below 5 or 2 ohms according to regulations). Fluctuations in the market and prices of copper, aluminum and silicon sheets have an immediate effect on the cost of transformers and overhead conductors. The branching length of the medium pressure network from the nearest existing line to the substation requires new foundations, which are included in the estimation of network implementation costs. Using the services of the Kelat specialized company ensures that the consumables are provided in a completely standard manner and at the most optimal cost in order to avoid paying excess costs.

Step-by-step implementation steps and estimation of medium pressure network implementation costs

Executive process of creating a standard air post requires certain engineering and administrative procedures so that the project is not stopped or rejected by the supervisors of the distribution company. In the first stage, field visit, technical calculations of consumption load and obtaining official branching permits from Shiraz Electricity Distribution Company are carried out. The second stage includes digging for the foundation of concrete foundations and drilling a specialized earth well. In the third stage, concrete or steel beams are installed, necessary bracing is done and crossarms are installed. In the fourth stage, the air post platform is installed and the transformer is placed at a height with a crane, and the arrangement of cables, lightning arresters and cut-out fuses is completed. In the fifth step, the low pressure distribution board is installed at the bottom of the beam and the cables are connected. Finally, the insulation tests, voltage injection and final delivery are done in coordination with the supervisors of the electricity company. The complete management of this route by Kelat Electricity reduces the risk of non-approval by network inspectors to zero and finalizes the process in the shortest possible time.

Estimating the costs of the air network and medium pressure lines in Shiraz

In many cases, the location of the aerial substation is not available in the direct vicinity of the 20 kV transmission lines, and the implementation of a sub-transmission line becomes inevitable. Estimating the costs of medium pressure aerial network implementation includes separate parts such as the cost of purchasing concrete beams with appropriate length and strength, airline fittings, plate or needle insulators and conductor wires (ACSR or medium pressure self-supporting cable). In addition to the cost of parts, the cost of machinery such as cranes, hoists, digging holes, wiring and insulation fees, and finally obtaining line safety clearance also affects the final price. With the field survey of the route, the experienced engineers of Kelat Electricity propose routes with the shortest line length, minimum natural obstacles and compatible with the network development plans, so that the total cost of the applicant can be significantly reduced.

The difference in the cost of air mails with different capacities

One of the key aspects in calculating the price of the construction of an overhead trans-electric substation in Shiraz is the exact determination of the demand or power required by the consumer. For small workshops or farms with low-power pumps, a 50 or 100 kVA transformer is the answer, which requires a lighter purchase cost and supporting structure. On the other hand, 250 and 400 kVA capacities are required for Shiraz Industrial Town factories or stone crushing and granulation units. More powerful transformers weigh more and therefore require concrete foundations with a higher tensile strength (such as 800 or 1000 dekN) and reinforced steel platforms. Also, the size of the communication cables, the capacity of the air or automatic switches in the distribution board and the cut-out fuses increase directly with the increase of the transformer capacity, which in turn affects the total costs. By performing a detailed power audit and predicting the future expansion of your collection, Kelat Electric prevents the selection of excessively large or small transformers and makes the most optimal investment.

Safety standards and requirements of Shiraz Electricity Distribution Company

Construction of medium pressure electrical facilities is highly sensitive and the slightest negligence can lead to irreparable loss of life and money. Shiraz Electricity Distribution Company has strict regulations regarding the airspace of masts and transformers, the type of connections, the permitted distance from buildings and roads, the type of fittings and the ground connection system. The resistance of the aerial post earth well must be measured and certified exactly to the specified standard; Because the correct discharge of overvoltages caused by lightning or network faults directly depends on the health of the transformer and the safety of the operator. The use of non-standard equipment or the implementation of the network by unauthorized teams usually leads to the rejection of the project by supervisors and the imposition of rework costs. Kelat Electric Company, as an official and recognized operator in Shiraz, carries out all the steps according to the latest instructions of Tawanir and provides a guarantee of obtaining technical inspection approvals.

Hidden costs and challenges of implementing air posts in different areas of Shiraz

Many employers, when starting the project, only calculate the price of the transformer and the base, and neglect other cost levels. Among these things, we can mention the cost of factory tests, transformer oil testing, heavy freight and specialized unloading, the cost of closing the passageway or coordination with the municipality, and most importantly, the cost of disconnecting the main power grid for the final connection (20 kV line shutdown). In some areas of Shiraz, such as mountain margins or rocky lands, digging and digging pits require compressor and picker equipment, which changes the cost of earthworks. The Kelat Electric team's comprehensive knowledge of geotechnics and the urban and rural structure of various areas of Shiraz, provides the possibility of providing a transparent, comprehensive pre-factor without hidden costs to the customers, so that the investor can enter the construction phase with full confidence.

The advantages of choosing air mail compared to ground or compact mail

Ground posts require the construction of a safe concrete chamber, proper ventilation, fireproof doors and the digging of underground cable channels, which greatly increase the cost of installation. In addition, occupying the useful area of ​​the project land is considered a big challenge in the situation where the real estate value is growing in Shiraz. On the other hand, the aerial post is suspended in the air on concrete foundations and does not occupy a lot of land, requires much less maintenance, and its implementation time is several times faster. If your load demand is in the allowed range of 50-400 kVA, without a doubt, the construction of an aerial post is the most cost-effective technical solution. Barq Kalat will help you choose the most economical and efficient solution by accurately measuring all aspects with an engineering analysis of site conditions.

Solutions to reduce the price of building an air post without losing quality

Decreasing operational costs should not be at the expense of the quality of vital materials; Because the use of poor equipment will quickly lead to the burning of the transformer coil, damage to the devices and irreparable accidents. The basic solution to reduce the price is to optimize the route of the airline network in order to use the shortest allowed route and to buy the equipment directly without the presence of non-specialist intermediaries. Using standard aluminum conductors instead of all-copper conductors in some permitted lines, choosing the transformer capacity according to the actual demand without overloading, and combining mechanical and electrical processes by a single contractor are among the most effective ways to significantly reduce the price of constructing an overhead power transmission substation in Shiraz.
