Product Description



The SC(B) series dry-type transformers are the pinnacle of modern engineering and technological innovation, delivering unmatched features that guarantee a reliable and efficient power supply solution.
With meticulous engineering, these transformers feature high-voltage windings crafted from top-grade enamelled copper wire and low-voltage windings composed of high-quality copper foil, ensuring both durability and peak efficiency. The high-voltage windings are expertly encased in strong glass fiber mats and sealed with imported epoxy resin under vacuum conditions, providing outstanding structural stability and integrity.
This precise process yields a strong, cohesive structure with exceptional mechanical strength, effectively eliminating partial discharge and considerably enhancing overall reliability.
Key advantages include:
F
Endowed with flame retardant, explosion-proof, and environmentally friendly characteristics, these transformers ensure zero pollution and are ideally suited for installation at load centers. and suitable for installation at load centers.

Specifically designed to resist moisture, the coils are crafted to prevent moisture absorption, with all components enduring 100% relative humidity without requiring moisture-proof treatments.
Demonstrating high resistance to short circuits and superior lightning impulse resistance, these transformers also support significant overload capacity, ensuring reliable performance even under extreme conditions.
Featuring advanced heat dissipation through a refined thin resin-insulated layer within the coils, they are generally cooled by natural air (AN), with a forced-air system (AF) recommended for protective class installations. class.
Characterized by low energy loss, these transformers provide excellent energy savings and cost-effectiveness, offering maintenance-free operation that highlights their remarkable value.
Compact, lightweight, and space-efficient, these transformers are designed for effortless installation, making them a preferred choice for various applications.
The SC(B) series epitomizes a new era of dry-type transformers, ideally suited for a wide range of applications, such as high-rise buildings, commercial centers, theaters, hospitals, mining enterprises, offshore drilling platforms, ships, underground facilities, airports, power plants, and residential areas.
