Product Description

Product Description

 

SCB13 resin insulated dry-type transformer is independently developed by our company by introducing advanced foreign technology. The iron core is made of high-permeability, high-quality grain-oriented cold-rolled silicon steel sheets, with 45&deg; fully oblique step joints. The iron core is made of special square tube pull plates. Structure, the core posts are bound with insulating tape, and the surface of the core is coated with special resin to prevent moisture and rust, which effectively reduces no-load loss, no-load current and core noise. At the same time, the scientific and reasonable design and pouring process make the product have smaller partial discharge, low noise, strong heat dissipation ability, and long-term operation under rated load under forced air cooling conditions.

Product Description:

The temperature control system from Shandong Zhifeng Transformer Co., Ltd. comprises a temperature controller and a PTC temperature measuring element positioned at the top end of the low-voltage winding, the hottest spot in the product. This setup enables precise temperature measurement and control of the transformer. In case of high winding temperature due to overload or faults, the temperature controller triggers an alarm signal and automatically trips when the temperature exceeds the safe limit. For transformers utilizing forced air cooling, the temperature controller regulates the cooling fan based on the winding temperature.

The temperature display system shows the hot spot temperature of the winding in real-time and can be used in conjunction with the temperature control system. Both systems can be installed at a distance from the transformer body, with the temperature measuring element's lead wire length specifications as follows:

• Temperature control: <20m


• Temperature display: <10m (two-wire system), <100m (two-wire system with compensating wire)

 

Performance Characteristics

• Low loss: The product's no-load loss is over 10% lower than SCB11 products, providing excellent energy savings and maintenance-free operation.


• Low noise: The product's noise level is 10-15 dB lower than the industry standard JB/T10088-1999 for transformer sound levels.


• Low discharge: Advanced resin mixture technology ensures minimal local discharge power, controlled below 5PC.


• Environmental protection, flame retardant: The vacuum and pressure poured coils offer a dense, flame-retardant, and pollution-free structure.


• High electrical strength: The sealed structure provides excellent insulation properties, arc resistance, and moisture resistance.


• High heat resistance: Epoxy resin encapsulation insulation offers high heat resistance up to grade H.
