The SC(B) series dry-type transformers are at the forefront of cutting-edge technology and innovation, offering unparalleled features that ensure efficient and reliable power supply solutions.
Crafted with exceptional precision, these transformers boast high-voltage windings made from the finest quality enameled copper wire while low-voltage windings utilize superior copper foil. This meticulous construction guarantees both durability and heightened efficiency. The high-voltage windings are expertly wrapped in robust glass fiber mats and hermetically sealed with the utmost precision, using high-grade imported epoxy resin under vacuum conditions. This process ensures remarkable structural integrity.
This meticulous process results in a powerful and cohesive structure, endowing the transformers with extraordinary mechanical strength, effectively eliminating partial discharge, and significantly boosting overall reliability.
These transformers, with their flame-retardant, explosion-proof, and environmentally friendly features, ensure zero pollution, making them the perfect choice for installation in load centers. and suitable for installation at load centers.
Featuring outstanding heat dissipation through an innovative thin resin-insulated layer within the coils, natural air (AN) cooling is typically employed, with a forced-air system (AF) recommended for installations requiring heightened protection. class.
With negligible energy loss, these transformers deliver excellent energy savings and cost efficiency, offering maintenance-free operation that accentuates their remarkable value.
Compact, lightweight, and requiring minimal space, these transformers are designed for seamless installation, making them an ideal choice for a diverse range of applications.
