Dongying City, Huayi Electrical and Mechanical Equipment Co., Ltd. special for the Great Wall SC (B), SG (B) series 35kV ..

SC (B), SG (B) series 35kV and below dry-type transformer Product Overview partial discharge value is low due to the coil cast in a vacuum, greatly prevent the coil of air bubbles, so partial discharge fully meet the relevant national standards regulations. The extent of damage and strong impact resistance to lightning impulse voltage lightning along the winding starting Distribution transformer winding insulation, foil windings starting voltage distribution is nearly linear, and therefore, the company's transformer has a good impact resistance to lightning. Strong resistance to short circuits foil width is reactance voltage winding height, low-voltage current by winding ampere-turns balance between the requirements of matches, high and low voltage windings due to short circuit caused by the axial force is almost zero. Our good crack resistance filler resin transformer and full foil structure, thermal expansion coefficient of the insulating material and copper conductors closest to effectively prevent cracking coil. The company has conducted a variety of anti-cracking test, such as alternating hot and cold test, thermal shock test and accelerated aging test, the test results show that the company's technology, particularly to meet a wide range of low temperature, high temperature and temperature changes of use, and can meet After long-running anti-cracking requirements. Overload capability if the same capacity transformer load loss equal, copper cross-sectional area of ??the corresponding amplification, volume increases, the amount of resin filler and more, so heat large capacitive winding transformer short strong overload. Retardant characteristics of a good use filler type resin casting process conducive to environmental protection, the company transformer has a maintenance-free, moisture, heat, flame retardant and self-extinguishing properties. In the high-temperature combustion arc, it does not produce any toxic gases. Retardant characteristics of the transformer to be confirmed in the combustion test. Our products have a good ability to adapt to the environment, according to European HD464 standards to meet the environmental rating of E2, weathering grade FC2, flame retardant rating of F1, can be used in commercial and residential areas, subway, power plants, ships, offshore drilling platforms and other environment and harsh conditions of the place. Low noise transformer I take some special structure and design, so that the noise is greatly reduced, the overall noise level than the national professional standard noise level low 2-3dB more. SCB9 low loss series with the commonly used domestic "8" type produce compared to an average of the total loss of 10 to 15%. With good economic returns.
