SCB10 Dry-type Transformer

The SCB10 dry-type transformer is a new product developed by Yibaling, a reliable factory in China. The core design lies in pouring high-quality epoxy resin in a vacuum environment and then curing it, completely sealing the windings to form a solid, moisture-proof, fire-proof, and maintenance-free insulation unit.

Therefore, it is flame-retardant, fire-resistant, explosion-proof, maintenance-free, and has a small size. The SCB10 dry-type transformer can be directly installed at the load center.

At the same time, our scientific pouring process makes the local discharge of the transformer smaller, with low noise and strong heat dissipation capacity.

As a dry-type transformer, it does not use flammable mineral oil at all, fundamentally eliminating the risks of fire, explosion and leakage pollution.

The flame-retardant and self-extinguishing characteristics enable it to be directly installed at the load center, such as in high-rise buildings, subways, hospitals, data centers, etc., which have extremely strict fire requirements.

Company Profile

Core Materials

The core of the SCB10 dry-type transformer is made of imported high-quality cold-rolled silicon steel sheets (usually of high magnetic permeability grades such as 30ZH120).

The unique full inclined seam stepped stacking structure can minimize the magnetic resistance and eddy current losses in the magnetic circuit, effectively reducing the no-load current and operating noise.

The surface of the core is tightly encapsulated with epoxy resin. This process not only serves the functions of moisture-proofing and rust prevention, but also significantly reduces the noise generated by the vibration of the core and prevents foreign objects from invading.

In terms of the winding structure, the SCB10 dry-type transformer adopts an enhanced design. The inner and outer walls of the coil are filled and supported by high-strength epoxy glass fiber grid plates (FRP). This design firmly combines the resin casting body and the conductor into a high mechanical strength whole.

This product greatly enhances the short-circuit electrical dynamic resistance and impact resistance of the coil, ensuring that the coil does not deform or shift under extreme current impact, fundamentally achieving the commitment of the coil never cracks.

This structural advantage directly translates into long-term value for users: It almost eliminates the failure risks caused by loose windings or insulation cracking, enabling the SCB10 dry-type transformer to truly achieve maintenance-free operation throughout its entire life cycle, significantly reducing potential maintenance costs and production losses caused by unexpected downtime for customers.

FAQ

Q: What is the main difference between SCB10 dry-type transformers and oil-immersed transformers? How should I choose?

A: The core difference lies in the insulation and cooling medium.

SCB10 dry-type transformer: The windings are cast with epoxy resin and cooled by air. Its advantages include safety and fire prevention (no oil, suitable for indoor and densely populated areas), environmental protection and maintenance-free (no risk of oil leakage, no need for oil maintenance), and flexible installation.

Oil-immersed transformer: Uses insulating oil as insulation and cooling medium. Its advantages are good heat dissipation, strong overload capacity, and lower cost, but it requires fire protection facilities and regular oil maintenance. It is usually used in outdoor or independent substations.

How to choose:

Select dry-type transformer (SCB): When the transformer needs to be installed inside buildings (such as basements, floors), data centers, subways, hospitals, commercial centers, etc., where fire safety and security are strictly required.

Select oil-immersed transformer: When the transformer is installed outdoors or in an independent substation, when the initial investment cost is sensitive, and there is sufficient environmental space and complete fire protection measures.

Q: Can the SCB10 dry-type transformer be directly installed indoors? What are the environmental requirements?

A: Yes, this is one of the core advantages of the SCB10 dry-type transformer. However, basic environmental conditions must be met to ensure its lifespan:

Cleanliness: The environment should be relatively clean, avoiding conductive metal dust and severe fiber dust.

Humidity: The relative humidity of the air should be ≤ 90%, and there should be no condensation. For damp environments such as basements, ventilation or a dehumidification device must be ensured.

Ventilation and heat dissipation: The transformer room must have good ventilation, and sufficient heat dissipation channels (usually ≥ 0.5 meters) should be reserved around it (as per product requirements). It is strictly prohibited to be sealed in a small space.

Fire prevention: Although it is self-flammable, it should still be installed in a dedicated transformer room that complies with fire safety regulations.
