30kVA 11kV Dry-type Distribution Transformer

Part I: Product Overview For 30kVA, 11kV Dry-type Transformer We adopt the advanced technology imported from Europe, patented technology, specialized software to optimize the design for 30kVA, 11kV cast resin dry type transformer. The core is made of cold-rolled grain-oriented silicon steel sheet which cut in step-lap by GEORG Germany TBA core cutting lines and laminated by the method of fifth-order step-by-step stacking technology, enabling the no-load performance of the core to improve greatly. The epoxy resin from American HUNTSMAN is adopted for the windings which casted in the vacuum resin casting machine imported from HEDRICH, Germany. The winding material ensures good permeability, no bubbles occur, which leads to minimum partial discharge. The HV and LV winding mate with each other tightly, which ensures solid strength of structure and capability to withstand short circuit and vibration. Under normal service condition, the service life of dry…
