Daelim Belefic three-phase oil-immersed small substation transformer is designed to use in the power distribution system.A substation is a component of a system that generates,transmits, and distributes electricity.Substations convert high to low voltage- or vice versa-and conduct a variety of other critical duties. Electricity may travel through many substations at varying voltage levels between the generating station and the customer.Transformers may be used in a substation to convert voltage levels between high transmission and low distribution voltages or to connect two separate transmission voltages.
A transformer with a capacity ranging from 300kVA to 10MVA is a medium-sized transformer that possesses the following characteristics:
High capacity: These transformers are capable of handling a significant amount of power transmission and distribution. They are suitable for medium-sized industrial, commercial, and residential areas.
High efficiency: These transformers are designed with efficient mechanisms and high-quality materials to minimize energy losses and maximize energy conversion efficiency.
Various cooling methods: Medium-sized transformers can be equipped with different cooling systems such as oil-immersed (commonly used in high-capacity transformers), air-cooled, or water-cooled.
Reliability and stability: These transformers are constructed using premium insulation materials and advanced manufacturing techniques to enhance reliability and stability.
Overload and short-circuit protection: Medium-sized transformers are often equipped with overload and short-circuit protection devices to safeguard against excessive loads or short-circuit conditions. These protective measures promptly disconnect the power supply, protecting the transformer and associated equipment from damage.
Customizability: Medium-sized transformers can be customized based on specific requirements such as input voltage, output voltage, and cooling methods.
