scb series dry-type power transformer


1. product introduction

our scb series epoxy resin dry-type transformer of 35kv level and below is made of h-level epoxy resin as insulation material, low-voltage winding is made of copper strip (foil), high-voltage winding is made of wire, epoxy resin is poured in vacuum and solidified to form a high-strength fiberglass structure. epoxy resin dry-type transformer has the characteristics of good electrical performance, strong lightning resistance, strong short-circuit resistance, small size and light weight. in addition, temperature display controller can be installed to display and control the operating temperature of transformer winding to ensure the normal service life of transformer. through introducing portuguese dry-type transformer technology and continuous improvement and optimization for more than 20 years, our company has upgraded and developed scb10, scb11, scb12 and scb13 series of dry-type power transformers, which meet the requirements of national standard gb / t10228, and completed all follow the principle of establishing the performance level code of dry-type transformer, among which scb12 achieves the second level of energy efficiency, and scb13 series products reach the first level of energy efficiency standard, which are widely used in national power grid, construction, energy, chemical industry, transportation, steel, industry, power generation and other fields, as well as in factories, residential engineering, business office, business center, data center and other fields.

2、 product features
◆ mature technology, advanced technology and first-class equipment
it is the first time in china to introduce advanced and mature technology and production process from portugal. by adding the most advanced georg iron core cross shear production line from germany and heidrich vacuum casting equipment from germany, the product design and manufacturing are in the leading position in the industry
◆ core materials, famous brands and quality assurance
baowu group directly supplies high-quality grain cold-rolled oriented silicon steel sheet, coil adopts high-quality oxygen free copper, copper content ≥ 99.95%
◆ economical, durable, cost-effective and widely used
◆ ultra low loss and energy saving products
scb10 and scb11 series products meet the three-level energy efficiency standard, scb12 series products reach the two-level energy efficiency, and scb13 series products reach the first level energy efficiency
◆ extremely low noise level is the best choice for distribution projects and commercial buildings
high quality cold-rolled oriented silicon steel sheet, seven step full oblique seam lamination structure, reasonable design of core width height ratio, the maximum noise reduction of products, noise level industry standard 10-15 decibels.
◆ intelligent monitoring, overload capacity and strong ability to resist sudden short circuit
it can be equipped with perfect temperature monitoring and protection system. the intelligent signal temperature control system can automatically monitor and display the working temperature of each phase winding on the same screen, automatically start and stop the fan, and have alarm, trip and other functional settings, which can not only ensure the safe operation under full load, but also have strong overload capacity after the fan is started, and can provide users with the overload demand under emergency conditions, with excellent short-circuit resistance.
