The 50 kVA transformer is a small‑capacity distribution unit, available in dry‑type and oil‑immersed versions for low‑load power supply sites.
50 kVA stands for apparent power. With a typical power factor of 0.8, its practical active load is around 40 kW. The common input voltage is 10 kV with 0.4 kV output, stepping down grid high‑voltage to usable low‑voltage for end‑users.
Oil‑immersed types feature low cost and good heat dissipation, widely used for rural outdoor power distribution and temporary construction sites. Dry‑type models are fire‑safe and smokeless, ideal for indoor rooms, shopping basements and small workshops. Copper‑winding variants deliver better overload performance and lower operating noise.
Typical application scenarios include small farm resorts, village partial power supply, small business clusters, outdoor base stations and compact equipment rooms. Long‑term full‑load operation should be avoided; 70‑80% loading is recommended for longer service life. Select proper protection grades for humid or dusty surroundings, where dry‑type units are often preferred.
