Single-Phase Overhead Distribution Transformer

Linkage Electric manufactures a series of single-phase overhead-type distribution transformers. Single-phase transformers are available as conventional (5~333 kVA) or as completely self-protected (CSP 25~167 kVA), offered in a variety of ratings to meet or exceed the requirements of applicable ANSI® and NEMA® standards. Units designed comply with Chinese Nation Standard and Taipower utilities service standards are also available. CSP transformers have direct connected primary arresters and internal primary voltage fuses, which eliminates the need for separately mounted protective devices and lowers installation costs. The overcurrent interrupter is an overcurrent protective device that protects distribution transformers from damaging overloads and secondary faults, and is also used for switching the transformer “on” or “off.”
