Design features

What the design is built around

Resistant to high temperatures and durable

Using epoxy resin casting technology, it has excellent temperature resistance and insulation performance far exceeding that of ordinary Dry Type Transformers. It can adapt to high-temperature power distribution environments, does not age easily, and the equipment service life is extended by more than 30% compared to traditional dry-type transformers, suitable for industrial high-temperature power distribution scenarios.

Highly adaptable and environmentally friendly

Oil-free design, no pollutant emissions. Compared to Oil Immersed Transformers, there is no need to handle waste oil. It meets the requirements of green development and can seamlessly connect with Box Type Substations and Electric Power Converters, compatible with the photovoltaic power transmission requirements of Combined Photovoltaic Substations, without the need for additional modifications.

Tips

This product is of a resin casting structure. During daily use, avoid sharp objects colliding with the equipment casing to prevent the resin from being damaged and affecting the insulation performance. Before purchasing, confirm the voltage level of the project to avoid mismatch.

Buyer questions

FAQ for SCB18 Resin Cast Dry-Type Transformer

What is SCB18 Resin Cast Dry-Type Transformer best used for?
This model is specified at the required capacity and 10 kV / 20 kV / 35 kV. It is used where the site load, fault level and environmental conditions match the approved datasheet. Share the load profile, ambient temperature, altitude and grid code and the design can be checked against the application.
What is the typical lead time for SCB18 Resin Cast Dry-Type Transformer?
Standard distribution units typically ship in 25-40 days after drawing approval. Large power transformers and integrated stations are scheduled by design review, core and winding production, tanking, testing and packing. The exact date is confirmed in the quotation.
Which standards and tests apply to dry-type transformers?
Dry-type units follow GB 1094.1, GB/T 6451 and IEC 60076-11. Routine tests cover winding resistance, ratio, impedance, no-load and load loss, insulation resistance and power-frequency withstand. Partial-discharge and temperature-rise type tests are available.
Can a dry-type transformer be installed outdoors?
A standard cast-resin unit is intended for indoor, well-ventilated rooms. For outdoor use an IP enclosure, anti-condensation heaters and a corrosion class must be specified. In many coastal or dusty sites an oil-immersed or prefabricated station is a better fit.
How do I choose between copper and aluminium windings?
Copper gives higher short-circuit strength and a more compact winding; aluminium can reduce first cost for lightly loaded units. The choice depends on fault level, load profile, loss evaluation and the buyer's specification. Both are available.
