Product Details

10kV three-phase Resin-cast insulation Dry-type Power Transformer

The core of the product is made of high-quality oriented cold-rolled silicon steel sheet material and adopts a five-step overlapping joint new process, which greatly improves the no-load performance of the core. The coil is vacuum cast with Huntsman epoxy resin, The epoxy cast dry-type transformer produced by our company can be used for power transformation and distribution of urban power grid. It is mainly applicable to high-rise buildings, commercial centers, airports, offshore drilling platforms, ships, tunnels, large hydropower stations, railway stations, etc.
