Daelim Transformer offers complete solutions for switchgear and switchboards in the low voltage and medium voltage areas. We offer solutions for the entire power distribution chain, not just for one voltage level.
If you are going to buy MV switchgear from one manufacturer, and LV switchboard from another, you must be prepared to coordinate their work. Daelim Transformer solves this with integrated production, in accordance with all standards, significant stocks and fast global delivery.
Our switchgear possess qualities that make them resilient in terms of appropriate safety features, easy maintenance, and level of automation.

The importance of purchasing electric distribution equipment from the same supplier has important and measurable benefits. This is an engineering decision that affects the way the plant is put into operation, the reliability and safety of protective devices and the consistency of documentation.
Daelim Transformer offers a compact switchgear and switchboard design, with a range of practical benefits for modern distribution systems:
| Feature | Advantages |
|---|---|
| Removable inspection plates and easy instrumentation access |
|
| Visual state confirmation |
|
| Remote control |
|
| Optional current and voltage sensor integration |
|
| Draw-out circuit breaker solution |
|
| Interlocks of incorrect switchgear operations |
|
| Integrated switchgear-transformer busbar connection |
|

Daelim Transformer switchgear solutions are designed to provide safe, reliable and efficient distribution of electrical power across a range of commercial, industrial, utility and critical infrastructure applications. Our solutions can be found in:
We are primarily manufacturers of transformers. This is important to emphasize because neither transformers nor switchgear are separate products. For this reason, our many years of experience help us develop compact solutions that include both transformers and switchgear. The advantages are manifold:
| Problem | Separate Vendors | Daelim Transformer Solution |
|---|---|---|
| Warranty issues | Each vendor has its own warranty and blames others for failures | Comprehensive warranty |
| Fault coordination | Complex analysis | The same engineers design the complete solution |
| Different lead time | Pending project | Delivery at once in the planned time |
| Spare parts | More manufacturers, more lead time | You contact Daelim Transformer for the complete solution |
All equipment is manufactured in one factory and fully FAT-tested. Upon delivery, everything is packed in one container and arrives to you as a complete delivery. Finally, you have a single point for any inquiries or after sales support.


Each switchgear order is made according to the customer specification. A wide range of parameters can be customized before the equipment is put into operation.

Each switchgear goes through rigorous tests in our factory before delivery. These tests consist of:
Third-party FAT testing can be arranged upon customer request. Daelim Transformer has UL, cUL and CE certifications and a quality control management system.
For integral solutions, the following is tested:
Checking bus connections and permissible loads
Our minimum warranty period is 24 months from commissioning. This period can be extended up to 5 years depending on the customer’s needs. One of the key benefits for the customer is that the warranty covers the entire package of equipment.

Our switchgear has electrical and mechanical interlocks that protect against improper handling, e.g. earthing connections while the equipment is energized. These interlocks are physical barriers, not just visual cues.
The compact secondary substation is a type-tested assembly consisting of LV switchboard, MV switchgear, distribution transformer, and connections in a single enclosure. This solution reduces complexity and unifies each plant.
Yes. We are a renowned company with research and development capabilities and we can adapt to any of your projects. It is important that you send us your project technical specifications and you will receive a technical solution with a budget estimate very quickly.
