    Features of Products

    With the advanced technology brought in from overseas we developed SC9, SCB9 series and SC10, SCB10 series padding thin-insulation dry-type distributing transformer whose winding is sealed up with epoxy, therefore theresin insulating dry- type transformer is flame-retardant, explosion-proof, free from maintenance and pollution, and it is compacted and can go deep into load center. Besides, with scientific and reasonable design and coating craftwork, it has advantages of low partial discharge capacity, low noise, good heat dispersion and it can run over a long time with 40% rated load in the circumstance of cold wind. It applies intelligent thermal controller and has the functions that it will alarm when there is fault or the temperature is exceeded and switch off as well as the function of “black box”. It can be monitored and controlled by connecting it to the computer through its RS485 serial interface. Therefore, it is widely used in the places such as hotel, restaurant, airport, power plant, hospital, skyscraper, shopping center, and residential areas and other adverse environments like subways, smelt and power plant, ship, offshore drilling platform, etc.

    Core

    The iron core adopts imported high-quality cold-rolled silicon-steel plate a three steps fully-inclined echelon ioint form. The colligation of the core adopts the F grade non-latitude belt and its winding enveloped by epoxy resin cast. The non-Load loss and non-load current. core noise are reduced. The outlook of the product is improved by special treatment of the surface of fasteners and clamp pieces

    High voltage winding

    High-voltage winding applies vacuum pouring of padding epoxy resin which, at high level, reduces partial discharge capacity and elevates the electric strength of coils. The inside and outside of the winding is buildup with glass fiber grid overlaywhich strengthens the mechanical robustness and improves the resistance of short-circuits and ensures the coils will never crack.

    Low voltage winding

    Low-voltage winding applies the structure that winded by copper foil which solves the problem that the axle would point to the helix angle when winds and make the ampere- turn of winding distribute evenly. Meanwhhile. the coils applies axial fan which improves the heat dispersion Between the layers of winding, it applies DMD epoxy resin preliminary dip cloth and makes it whole solidification forming.

    Production technology

    The coil can be wound on the high-accuracy winding machine, the low-winding adoption the structure that the winding by cooper foil. Firstly, to cast grass fiber around the extemal and internal of the windings, there designed to be armed air passage for transformer of large capacity. Afterward, to vacuum dry it. The whole casting and solidifying process completely to carry on an operation according to the craft request and see a circumstance to carry on adjustment. The precise process ensures free bubble and free hole of winding. make the transformer for making into attain superior quality circulate result.
