Design features

What the design is built around

Ultra-low loss energy-saving design

The SC (B) 14 series uses a new type of low-loss core material. Compared to conventional dry-type transformers, the no-load loss is reduced by approximately 10%, and the load loss has also been optimized. Long-term operation can significantly reduce the electricity cost for enterprises, especially suitable for industrial and commercial high-load scenarios.

Low noise operation performance

Through optimizing the winding structure and shock absorption design, the operating noise of the equipment is significantly reduced, meeting the usage requirements of noise-sensitive areas such as office areas and commercial areas, and reducing the impact of equipment operation on the surrounding environment.

Practical Tips

When installing, sufficient maintenance space should be reserved to facilitate subsequent maintenance operations. At the same time, ensure that the grounding system is reliable to guarantee the safe operation of the equipment.

Before the equipment is put into operation, insulation resistance tests and wiring checks should be conducted to confirm there are no errors. Only after confirming everything is correct can it be operated under load to avoid faults caused by incorrect wiring.

Buyer questions

FAQ for 1250 kVA Dry-Type Transformer

What is 1250 kVA Dry-Type Transformer best used for?
This model is specified at 1,250 kVA 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 1250 kVA 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.
