Product description
Dry-type transformer is our company introduced foreign advanced technology, independently developed SCB10, SCB11 series of thin insulated dry-type transformer with packing, because the coil is encapsulated by epoxy resin, so it is flame retardant, fireproof, explosion-proof, maintenance-free, pollution-free, small size, can be directly installed in the load center. At the same time, the scientific and reasonable design and pouring process make the product less partial discharge, low noise, strong heat dissipation capacity, can operate for a long time under 125% rated load under forced air cooling conditions, and is equipped with intelligent temperature controller, with fault report*, overtemperature report*, over-temperature trip and gate function, and connected to the computer through the RS485 serial interface, which can be centrally monitored and controlled. According to different use environments, shells with different protection levels can be configured or not configured, which are suitable for important or special environmental places such as high-rise buildings, commercial centers, airports, tunnels, chemical plants, nuclear power plants, and ships.
The dry-type transformer is made of high-quality materials and scientific formula, and is produced by advanced production and testing equipment according to strict technology.
Features:
Voltage level 10-35kV, transformer capacity SC10, SCB10-3~2500kVA, the transformer is our company on the basis of digestion and absorption of the introduction of technology research and development of 35kV insulation dry-type transformer, the design and manufacture of products are to meet the requirements of IEC60076, GB6450, GB/T10228 and other standards, the products are widely used in power plants, power stations, industrial and mining enterprises, user distribution stations and other power and distribution systems, the product has the following characteristics:
