The SC(B) series dry-type transformers represent the pinnacle of modern engineering excellence and revolutionary technological advancements, offering unparalleled features that ensure efficient and reliable power distribution solutions for all your energy needs.
Expertly designed for peak performance, these transformers incorporate high-voltage windings meticulously crafted from superior-grade enamelled copper wire, coupled with low-voltage windings made from exquisite copper foil. This design guarantees exceptional durability and efficiency. Each high-voltage winding is encapsulated in robust glass fiber mats and hermetically sealed with premium imported epoxy resin under vacuum conditions, providing extraordinary structural integrity and reliability.
This precise manufacturing approach delivers a resilient, cohesive structure possessing exceptional mechanical strength, effectively eliminating partial discharges and significantly enhancing overall system reliability.
Key advantages include:
Renowned for its flame-retardant, explosion-proof, and environmentally friendly characteristics, these transformers are both non-polluting and perfectly designed for installation at load centers, ensuring safety and sustainability. and are especially suitable for installation at load centers.
Emphasizing moisture resistance, the coils are engineered to effortlessly resist moisture absorption. Every component is crafted to withstand 100% relative humidity, eliminating the need for additional moisture-proof treatments and ensuring long-lasting durability.
Exhibiting superior resistance to short circuits and exceptional lightning impulse resilience, these transformers also feature a significant overload capacity, ensuring robust and consistent performance even under the most challenging conditions.
Equipped with highly efficient heat dissipation, thanks to an advanced thin resin-insulated layer within the coils, these transformers are generally cooled by natural air (AN). For installations requiring extra protection, a forced-air system (AF) is recommended. class.
With remarkably low energy loss, these transformers deliver outstanding energy savings and cost-efficiency, offering maintenance-free operation that underscores their superior value and exceptional performance.
Compact and lightweight, these transformers require minimal space and are designed for effortless installation, making them an ideal energy solution for a wide array of applications.
