Category-Wise Insights:

By Core

• Berry: The berry core which consists of the core assembly and additional components in an oil filled transformer is one of the most significant parts that influences the functioning and efficiency of the transformer. The berry core is primarily made of laminated silicone steel formed in such a way to avoid energy losses due to hysteresis and eddy currents so that the transformer can work efficiently. The core also helps in the transfer of the magnetic flux between the primary and secondary winding during the process of the voltage conversion which enables an effective transformation of the voltages.

• Shell: Shell is one of the cores of an oil-filled transformer which enhances the performance internal structural feature of the transformer. Instead of a traditional arrangement of cores, the shell core configuration allows the windings to be surrounded by the core, thereby forming a magnetic field in the closure. The design limits the amount of dispersed magnetic field and enhances the magnetic ability of the transformer resulting to minimal energy waste in the process of energy conversion.

• Closed: The closed core of an oil filled transformer is a design that not only increase the functionality but also the efficiency of the transformer, Thanks to the combination of these two techniques, the core is formed in a closed rectangular loop which draws the magnetic circuit fence in the core and the walls of the core with minimal magnetic leakage- the magnetic circuit is fully ingested within the coring material. This configuration enhances greatly the magnetic efficiency of the transformer because the parts of the magnetic field that are not used and escape are minimized.

By Winding

• Auto-Transformer: The auto-transformer winding within an oil-filled tank is a unique feature used primarily in the improvement of the voltage transformation ratio and for optimally reduction of the material bulk. In addition to that, most traditional transformers have primary and secondary windings which are separate from each other. An auto-transformer has in the simple sense, one winding which does both the jobs simultaneously.

• Two-Winding: As the name suggests, the two-winding compartment of an oil-filled transformer is the simplest form of construction, whereby primary and secondary windings are provided which perform different functions with respect to voltage conversion. This conventional design allows for the effective coupling of electrical power between circuits using electromagnetic induction without the need of physical connection between the two circuits.

By Product

By Mounting

• Foundation: The mounting of oil-filled transformers on their foundations is of utmost importance to the value and the safety of the transformer itself and to its effective working. Proper consideration shall be given to the design of the foundation, particularly in view of the transformer’s substantial weight, which for oil-filled units, is largely due to the oil and robust design. A reinforcement concrete pad is the most common type of foundation used, where it offers a flat and solid surface to evenly spread the load and reduce any sinking effects over a period.

• Pad: Pad mounting of oil fill transformers is a popular installation method, which offers the necessary structural support to this input/output equipment in the electrical systems. In this arrangement, a transformer is placed on a concrete slab that is meant to cushion its weight evenly and avoid sinking or moving due to vibrations over time. The thick concrete structure is typically reinforced to carry the load requirements of the transformer and more so its inner oil load.

• Pole: Pole mounting of oil filled transformers is another popular installation method used especially in the countryside and suburbs that have many overhead power lines and little ground space available. The transformer in this case is placed on a utility pole which serves to elevate the transformer and conveniently connects it with other overhead lines. This method of mounting also enables full utilization of space available and minimizes on flooding threats as well as threats from fallen objects or vehicles.

• Others: The other segment comprises skid mounting, and ground mounting. In this technique, the transformer is mounted on a firm, yet portable support structure or skeletal frame called a skip which makes its design ideal for short-term applications or sites where the transformer is subjected to reinstallation. In ground mounting, transformers are placed on a soil prepared area often incorporating gravel for drainage at a minimal cost which is ideal in situations where land is not the limiting factor.

By Substation Connectivity

• Transmission: The ability to connect a transmission substation is an important feature of oil-filled transformers allowing the effective transition of electrical energy from a more extensive high-voltage transmission lines to a lower voltage distribution line. These transformers are an essential element of the electrical power network and perform the function of reducing the voltage in order for the delivered current to be fit for use amongst the consumers.

• Distribution: The distribution substation connection is the last oil-filled transformer that connects a distribution system with end-users, which has ever been referred to as an electric power delivery system. These transformers bring the voltage down from the very high levels used in the transmission system to lower levels appropriate for use in homes, businesses and industries.

By Application
