Transformer 12kv 24kv 36kv Dry Type 15kva 100kva 1000kva Power Supply Transformer

Product Characteristics

With the advanced technology brought in from averseas,we developed SC10,SCB10 series and SC11,SCB11 series padding thin-insulation dry-type distributing transformer whose winding is sealed up with epoxy,therefore the resin 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,The product has a small partial discharge, low noise and strong heat dissipation capability. It can be equipped with an intelligent temperature controller with fault alarm, over temperature alarm and over temperature trip. And the black box function, and connected to the computer through the RS485 serial interface, can be centralized monitoring and control.

Our company's dry-type transformers are widely used in transmission and transformation point systems, such as hotels, restaurants, airports, high-rise buildings, commercial centers, residential quarters and other important places, as well as subways, smelting power plants, ships, marine drilling platforms and other environmentally harsh places.

Iron Core
The iron core is made of imported high-quality cold-rolled silicon steel sheet, which is fully connected with oblique seam structure. The core column is banded with F-grade non-weft adhesive tape. The surface of the core is encapsulated with epoxy resin, which reduces the no-load loss, no-load current and core noise. Parts and fasteners are specially surface treated to further improve the appearance quality of the product.

High Voltage Winding
The high-voltage winding is vacuum-cast with filled epoxy resin, which greatly reduces the partial discharge and improves the electrical strength of the coil. The inner and outer walls of the winding are filled with glass fiber mesh plates, which enhances the mechanical strength of the coil and improves the product against sudden short circuit. The ability of the coil will never crack.
