better to know to a 315 kva mini substation

2024-04-01

A 315 kva mini substation is an electrical facility, which combines a distribution transformer, control and operation panels into a sealed box. It has a compact structure, which has advantages of convenient to install and deliver. Normally, the primary side connects with power gird through inlet cable, vacuum circuit breaker and isolating switch. The secondary side distributes electricity to users, which steps down the voltage to an appropriate level through the 315 kva distribution transformer.

Conso Electrical Science and Technology Co., Ltd is a specialized manufacturer to produce 10kv to 35kv electrical facilities, such as compact substation, distribution transformer and vacuum circuit breaker. In Conso Electrical, it could produce 315 kva oil immersed transformer,315 kva cast resin transformer, 315 kva pad mounted transformer and 315 kva compact substation.



In Conso Electrical, it has a professional team to design and manufacture 315 kva mini substations, where the experience come from cooperating with clients. The company exported 35 kv solar compact substation to Samoa, 10 kv distribution substation to Chad, and 35 kv oil immersed transformer to Cameroon. Conso Electrical aims to establish a stable relationship with distributors and terminal users.

What is a315 kva mini substation used for?

A 315 kva mini substation is an electrical equipment usually to be use as steps down voltage level and distributes electricity. The following is the main area a 315 kva substation could apply:

1. Industry companies: factories, manufacturing plant and industrial park has a large demand to drive manufacturing equipment and machines.

2. Commercial electricity: it needs power to support lighting, air conditioner, and elevator lifting system in a commercial building such as shopping malls and office buildings.

3. Residential area: it needs a stable power supply to a large or high rise residential area to support electricity to lighting, heating and cooling system.

4. Medical Facilities: a hospital need a 24 hours uninterrupted power supply to operate surgery, take care of patients, and run other necessary equipment.

5. Educational and research institutions: it requires large amounts of electricity to support teaching, scientific research experiments, and equipment operations in universities, research laboratories and schools.

What are the three types of substations?

A 315 kva mini substation could have those three types overall:

1. 315 kva step down compact substations: it mainly distributes electricity from power plant to commercial, industrial and residential usage.Meanwhile, a 315 kva step down distribution substation could improve the stability and reliability for power supply system.

2. 315 kva step up compact substation: it mainly transmits electricity from solar and wind power plant to a city or a town in long distance.The solar and wind power plant create amicro-gird environment, which needs a lower capacity substation to transmit electricity compare with the thermal and hydroelectric power plant. Meanwhile, a 315 kva step up compact substation also apply to power supply line switching as the voltage level could be different between two areas.

3.  315 kva semi-buried compact substation: normally, the distribution transformer is installed below the control panels, which saves more land for the electricity consumer unit such as CBD, city park, and office building. Meanwhile, a 315 kva semi-buried compact substation could create a more pleasing view for surroundings.

What is the load capacity of a315 kva mini substation?

Obviously, the 315 kva is the total power to a 315 kva mini substation could supply. However, not all power could apply to energy conversation. A part of power, which is called reactive power, is used to keep the power gird stable, and enhance the power factor. Normally, the power factor can not be lower than 0.9 in most of countries and areas. Thus, a 315 kva mini substation could supply at least 283.5 kW active power for users.

Meanwhile, it needs to notice that an appropriate load rate could extend service life and reduce electricity losses. Normally, the ideal load rate is 50% to 80% to a compact substation.


How much voltage is in a315 kva mini substation?

In Conso Electrical, it could produce any 315 mini substation, which the primary voltage is from 6kv to 35kv. Conso Electrical mainly has produced 10/0.4 kv, 15/0.4 kv, 20/0.4 kva and 35/0.4 kv 315 kva mini substation since 2006. the distribution transformer in the 315 kva mini substation could be oil immersed transformer, cast resin transformer or amorphous alloy transformer. The company offer multiple option of solution to terminal users.

What is the loss of a315 kva mini substation?

The standard of loss is different between countries and areas. The following table shows the each loss standard of a 10kv 315 kva mini substation:

Tips: 

1. the left side of load loss is for Dyn11 and the right side is for Yyn0;

2. The number of 1.4 in no load current is the standard value and the 0.72 is the advanced value.


What is the cost of a315 kva mini substation?

In Conso Electrical, each of 315 kva mini substation customizes as the requirement from clients and the IEC standard. Meanwhile, the manufacturing costs also is impacted by the current price of raw materials such as copper, silicon steel sheet, and branded components. The costs of A 315 kva mini substation could be around $ 11500 to $15000, however, the costs will be totally different, if clients need branded components.


A315 kva mini substation is for sale.

   315 kva mini substation is one of the main product in Conso Electrical. The company takes different materials to meet the local working environment where the product will be installed. For example, Conso Electrical will use 1.8mm galvanized sheet to make shell for oversea clients, as the corrosive air during sea shipping. Meanwhile, some components such as cable plugs and insulators will be adopted as the creepage distance will increase with the sea l
