Construction of JLSZW Combined Transformer
The JLSZW combined transformer is built with precision and high-quality materials to ensure reliable and long-lasting performance. The voltage transformer uses an epoxy resin casting mechanism with an exposed iron core, made from grain-oriented cold-rolled silicon steel sheets. The primary and secondary coils are mounted on a central post, ensuring stability and accurate voltage transformation.
The current transformer features a closed iron core with an epoxy resin casting mechanism. It is constructed using a rolling process with premium grain-oriented cold-rolled silicon steel sheets, providing excellent magnetic properties and durability.
Two voltage transformers (PT) and two current transformers (CT) are integrated into a single sealed iron box, forming a compact and unified structure. This design ensures high reliability, minimal maintenance, and suitability for outdoor applications in high-voltage power distribution systems and energy metering.
