Cryptocurrency is a virtual currency created by a computerized code, through a process called ‘mining’. There is a big difference between conventional currencies and cryptocurrencies. Conventional currencies are centralized and under supervision, meanwhile cryptocurrencies are decentralized, which means, these currencies are not controlled or supervised by anybody.


Design a power distribution system for mining is a very difficult task that requires a lot of experience and a prepared team with knowledge to be able to develop the best projects. For this reason, Daelim has a big team of professionals who can provide you with the best solutions for your crypto mining projects.


We all know that the main equipment for mining Bitcoin is the mining machine. Every crypto mining farm has hundreds or thousands of mining machines, or even more. These miners require transformers to provide a stable power supply. If you want to make Bitcoin mine work well, you have to know how to choose the most suitable transformer for your crypto minging.

Design a power distribution system for mining is a very difficult task that requires a lot of experience and a prepared team with knowledge to be able to develop the best projects. For this reason, Daelim has a big team of professionals who can provide you with the best solutions for your crypto mining projects.
The transformer mainly provides electricity for the crypto mine. Depending on the type of transformer, oil-immersed transformers are the best choice for crypto mining mining. The main transformers that can be used for crypto mining are pad-mounted transformers and small substation transformers. Both types of transformers are oil transformer, they have good mechanical and electrical properties, simple installation, easy maintenance, and high cost performance.
For one side, as we mentioned before, one of the best options for cryptocurrency mining is the type of Pad mounted transformers.

In general, the common voltage used for Pad mounted transformers are 27.96kv, 4.5kv, 13.8kv, which finally converts into a usable low voltage than come in three main configurations:  208V 3 Phase Delta, 240V/415V 3 Phase Wye, 480/277V 3 Phase Wye.
The primary voltage is the one that provide the utility, and the secondary voltage is the one that will provide the power for the cryptomine. 
If we have to choose the best configuration, no doubt we choose 415/240V. Why we choose this one? Is the most efficient voltage and has the lowest circuit breakers costs in the main panel.
Every unit of Daelim Pad mounted transformer will include the standard accessories like thermometers, oil level gauges, pressure vacuum gauges, also on/off load break switches, bayonet fuses, etc.
This transformer is what we call primary equipment, which are designed in a way that they do not need to receive continuous maintenance or revisions. Thanks to this, it improves the reliability of the power supply, thus reducing energy and maintenance costs.

At the same time, Daelim Small substation transformers is also a good option for your crypto mining solution.

Like another type of transformer, the Small Substation transformer converts primary energy into usable secondary for Bitcoin mining.

Here, we going to introduce you some of our latest project we did in America market for your reference: 

NA project for your reference:

4 units of Pad mounted transformer
Capacity: 2500kVA
HV: 24.94kV
LV: 415/240V
Dead front, Loop feed
IEEE C.57.12.00 standard
This is one of our latest projects we did for Bitcoin mining in North America market. 2500kVA of capacity, input voltage 24.94kV and output voltage 415/240V, is one of the best solutions in terms of transformers for Bitcoin mining, based on our project experience.
Once the client contacted us, we gave him a quick response, to be able to offer a quote on time and that the client could be satisfied. After the confirmation of our client, we sent the next day to the customer the quotation based on our customer requirements. We offered him a really competitive price and a fast delivery time. These 4 units of 2500kVA Pad mounted transformer were loaded in a 40HQ container.
Thanks to that, after few days, we receive our customer feedback, being really satisfied with our solutions and service.

Project cases we did for Venezuela market for your reference:

crypto mining solution (1)

The picture above shows that a Venezuelan customer bought 4 Daelim substation transformers and used them in their own 20MW Bitcoin mining farm.

4 units of Small substation Transformer

Capacity: 4500kVA

Primary voltage: 13.8kV

Secondary voltage: 380/220V

Vector group: Dyn11

Standards: IEEE C.57.12.00/ IEEE C.57.12.90

Control Box

Our client from Venezuela, asked us to design 4 units of Small substation transformer with 4500kVA capacity. One of their requirements was to include in the design the control box. Through the control box we can control the equipment and its performance. The control box must be located, adjacent to the box that protects the bushing on the low voltage side, as indicated in the highlinhted box.

After weeks of cooperation, these 4 units were successfully shipped and they are already operating.

Capacity: 2500 kVA

Primary voltage: 15kV DELTA

Secondary voltage: 480GrdY/277

Shipping fee 50 container, 2 units per container

In this case, our client contacted us and introduced us his substation project. The total substation project was 250MW, and he asked us if we could design a plan for him. Our professional team of engineers designed a plan that consisted of 100 units of 2500kVA Pad mounted transformer with primary voltage: 15kV DELTA, secondary voltage: 480GrdY/277.

One of the main requirement of this client for this project was that the Switchgear be included with the transformer.

As we already know, Daelim is a transformer manufacturer, so this client’s requirement wasn’t in our business range. After several days of hard work and research, Daelim offered the client the complete solution, 2500kVA Pad mounted transformer with Switchgear. This complete solution was loaded in 50 40HQ container, 2 units per container.

The shipment was made successfully and our client was very satisfied with the solution we designed for.
 For Daelim, our production capability is to provide 100 ~ 200 units in 4 months. According to this, we can provide the customer the fastest delivery time and very competitive prices.
