Liwang as a professional manufacturer of three-phase dry-type transformer, the quality of the company's three-phase dry-type transformer is hard enough and cost-effective. Here, we introduce the technical characteristics of liwang's three-phase dry-type transformer, and welcome the majority of users to purchase.
Technical features of three-phase dry type transformer:
1. The initial distribution of lightning impulse voltage along the winding affects the damage degree of transformer winding insulation. The initial voltage distribution of foil winding is close to linear. Therefore, liwang's three-phase dry-type transformer has good lightning impulse resistance.
2. The resistance to short circuit is strong. The width of copper foil of low voltage winding is the height of reactance. The low voltage current is matched according to the requirements of ampere turn balance between windings. The axial force of high and low voltage windings caused by short circuit is almost zero.
3. The transformer adopts the structure of filled resin and copper foil. The thermal expansion coefficient of insulation material and copper conductor is the closest, which can effectively prevent coil cracking. The company has carried out a variety of anti cracking tests, such as cold and hot alternating test, thermal shock test and rapid aging test. The test results show that the technology of zhongbian company can meet the application occasions of low temperature, high temperature and wide temperature range, and can meet the anti cracking requirements after long-term operation.
4. If the transformer with the same capacity has the same load loss, the cross-sectional area of copper foil will be correspondingly larger. After the volume increases, the amount of filler resin will be more. Therefore, the thermal capacity of the winding is large and the short-term overload capacity of the transformer is strong.
5. The three-phase dry-type transformer has the characteristics of maintenance free, moisture protection, moisture resistance, flame retardant and self extinguishing. In the high temperature combustion of the arc, no toxic gas is produced. The company's excellent flame retardant properties have been confirmed in the combustion test. According to the European HD464 standard, the product meets the requirements of E2, FC2 and F1. It can be used in commercial and residential areas, subways, power plants, ships, offshore drilling platforms and other places with poor environment and service conditions.
6. The noise level of the transformer is 10-13db (a) lower than that in the national professional standard.
7. Compared with the "8" type products commonly used in China, the total loss is reduced by 10-15% on average. It has good economic benefits.
The three-phase dry-type transformer produced by Liwang Electric is not only hard but also cost-effective. The most important thing is that our after-sales service is absolutely second to none.
