Description
Parameter

At the core of the SCB10-5~100 series transformer's high and low voltage windings lies its vacuum pressure resin casting process. This process ensures the windings possess insulation properties and impact resistance, manifested as low partial discharge and strong short-circuit resistance. These characteristics are critical for guaranteeing stable operation in confined or sensitive environments. Furthermore, both the windings and core surfaces are encapsulated by solid insulation, imparting superior moisture-proof and mold-proof qualities, enabling reliable and efficient operation even under humid or adverse conditions.

As an oil-free transformer, the SCB10-5~100 series eliminates common issues associated with traditional oil-immersed transformers, such as oil deterioration and sealing failures, thereby requiring no routine maintenance. Its inherent properties of being safe, fireproof, and pollution-free, coupled with its flame-retardant and self-extinguishing capabilities, allow it to be safely deployed directly near load centers. This offers significant advantages in enhancing power supply reliability, reducing transmission losses, and optimizing urban space utilization.

The SCB10-5~100 series prioritizes compactness and lightweight design, which facilitates easier installation. Its characteristic low operational noise also makes it highly suitable for installation in noise-sensitive areas. In terms of electrical performance, this series of transformers typically has a short-circuit impedance of 4.0%. The standard configuration includes a 10kV high voltage side, a 0.4kV low voltage side, and a Dyn11 connection group. These parameters make it ideal as a voltage transformation device at the end of distribution networks, flexibly adapting to various application scenarios.
