Product Description


Precisely engineered, these transformers feature high-voltage windings made from superior enamelled copper wire and low-voltage windings crafted from premium copper foil, ensuring exceptional durability and efficiency. The high-voltage windings are meticulously encased in durable glass fiber mats, hermetically sealed with imported epoxy resin under vacuum conditions, delivering outstanding structural integrity.
This meticulous process results in a robust, unified structure with extraordinary mechanical strength, effectively eliminating partial discharge and significantly enhancing overall reliability.
Key advantages include:
F
Featuring flame-retardant, explosion-proof, and eco-friendly attributes, these transformers are pollution-free and perfectly suited for installation at load centers. and ideal for installation at load centers.
