Features of SCB11, SCB12, SCB13, SCB14, and SCB18 series resin-insulated dry-type power transformers:

Safe, flame-retardant, pollution-free, can be directly installed at the load center without maintenance, easy to install, and has low overall operating costs.

It has excellent moisture resistance, allowing normal operation at 100% humidity, and can be put into operation immediately after shutdown without pre-drying. It features low loss, low partial discharge, low noise, and strong heat dissipation; it can operate at 150% rated load under forced air cooling. Equipped with a comprehensive temperature protection and control system, it provides reliable protection for the safe operation of the transformer. It boasts high reliability; based on operational studies of products already in service, its reliability indicators have reached international advanced levels.

Structural features of SCB11, SCB12, SCB13, SCB14, and SCB18 series resin-insulated dry-type power transformers :

Box-type coils: The low-voltage winding uses a single section of copper foil, along with Class F insulation, wound on a specialized low-voltage foil winding machine . Foil-type coils effectively solve prominent problems associated with low-voltage, high-current coils , such as high short-circuit stress, ampere-turn imbalance, poor heat dissipation, and inconsistent winding helix angle and manual welding quality. Furthermore, our company uses resin potting at the winding ends for curing and shaping, providing moisture and contamination protection. The copper busbars are automatically welded using hydrogen arc welding.

Temperature control device: The transformer adopts BWDK series signal thermometers. The temperature sensing element is embedded in the upper half of the low-voltage coil. It can automatically detect and display the working temperature of each phase coil in turn, and has over-temperature alarm and trip functions.
