Nov 10, 2025
Leave a message
The rated power of the oil transformer is 50 KVA. It is a step-down transformer 11kv to 0.415kv, the primary voltage is 11kv, the secondary voltage is 0.415kv. It is a hermetically sealed transformer without conservator, it can make transformer oil completely isolated from the air and sunlight to avoid oxidation and moisture of transformer oil, so as to slow down the aging speed of transformer insulation and prolong the service life of transformer. Our 50 KVA distribution transformer was designed with advanced technology and adopts high quality material and components which result in reliable quality and long operation time.

50 KVA 11KV Oil Filled Transformer applications and functions
- Power distribution: Reduces high-voltage electricity from the transmission grid to a lower, safe voltage for use in neighborhoods and smaller commercial areas.
- Residential and commercial use: Powers buildings and serves the electrical needs of residents in a local area.
- Lighting: Supplies power for public and private lighting systems.
- Powering equipment: Provides a stable voltage for a variety of electrical and electronic equipment, instruments, and other devices.
- Small-scale industries: Used in smaller industrial settings that require a lower voltage for their machinery and operations.
- Renewable energy: Can be used in smaller renewable energy generation projects to step down voltage for distribution.
Benefits of the oil-immersed design
Cooling and insulation: The oil circulates to dissipate heat from the windings, which improves efficiency and performance. It also provides electrical insulation for the components.
Durability: Oil-immersed transformers are often designed to be robust and can withstand harsh or corrosive environments, making them suitable for outdoor use.
Extended lifespan: By isolating the internal components from air and moisture, the oil helps slow down the aging of insulation, prolonging the transformer's service life.
