             A pole-mounted transformer is a type of distribution transformer that is mounted on a utility pole. It is used to step down the voltage of electrical power from high voltage transmission lines to a lower voltage suitable for distribution to homes, businesses, and other end-users. The pole-mounted transformer typically consists of a transformer unit, which includes the core and windings, mounted on top of a pole. Pole-mounted transformers are commonly used in rural areas or areas with distributed electrical infrastructure.These are several core types used in pole-mounted transformers, including:Shell-type core: This type of core consists of two cylindrical or toroidal-shaped cores that surround the windings. It provides efficient magnetic coupling and allows for easy cooling.Core-type core: This type of core has a rectangular or E-shaped core that encloses the windings. It is widely used in distribution transformers due to its compact size and high efficiency.Toroidal core: This type of core is donut-shaped and provides excellent magnetic coupling, low no-load losses, and compact design. It is commonly used in single-phase pole-mounted transformers.These are some of common core types used in pole-mounted transformers, but there maybe other variations depending on specific requirements and manufacturer preferences.Transmart designs and manufactures two popular types cores, one is Distributed gap wound core, the other is a Folded Octagonal Core or called Unicore. Both are for pole-mounted distribution transformers, ranging from 5KVA to 500KVA,  single phase and three phase available            Distributed gap wound core is a type of core used in pole-mounted transformers. It is a variation of the shell-type core, where the windings are distributed along the core with gaps between them. This design helps to reduce losses and improve the performance of the transformer. Distributed gap wound cores are often employed in high-power distribution transformers.The advantage of a distributed gap wound core is that it helps to reduce losses and improve the performance of the transformer. The gaps between the windings help to minimize eddy current losses and reduce the leakage flux, resulting in higher efficiency. This type of core also provides better cooling and allows for easier maintenance and repair of the windings. Additionally, distributed gap wound cores are often used in high-power distribution transformers, making them suitable for applications requiring higher power handling capabilities.The materials commonly used for distributed gap wound cores in pole-mounted transformers are typically laminated steel or amorphous alloy. Laminated steel is a traditional choice due to its low cost, excellent magnetic properties, and easy availability. Amorphous alloy, on the other hand, is a more advanced and efficient material that offers lower core losses and improved energy efficiency. Manufacturers may choose either of these materials based on their specific requirements and cost considerations.Manufacturing porcess of a distributed gap wound core involves several steps. Here is a general overview       Step.1DesignThe design of the core is based on the specific requirements of the transformer, such as voltage rating, power capacity, and magnetic properties.       Step.2Material selectionThe appropriate material, is selected based on factors like cost, efficiency, and availability.

Amorphous Coresare used in almost every piece of electronic equipment we know about. These are found in transformers, Charging devices, and even components of computers. They are often used as chokes, a central core with multiple insulated wires wound around it to make an efficient magnetic core.Though we have different types of cores, including amorphous, ferrite, silicon steel, non-crystalline, and more, we will mainly focus on the Amorphous Cores in this article. Dive into this comprehensive guide and learn everything you should know about these cores! What to Know About Amorphous Cores?Amorphous Cores are made of metallic glass metallic without any well-defined crystalline form. Depending on their amorphous structure, these cores offer improved electric conductivity, efficient functioning, higher permeability, and increased magnetic density over a diverse range of temperatures usually not tolerated by other types of cores due to their low Curie temperatures. These cores are made from the process of solidification of the molted metal. Amorphous Cores are actually soft magnetic materials boasting stacks and stacks of silicon steel lamination. Their notable properties include high electric resistivity, relatively improved mechanical characteristics, and excellent magnetic and electromagnetic properties. Moreover, you can find these cores in multiple different types, including E-core, C-core, Amorphous Toroidal core, Shell core, Cut core, Block core, Planner core, U-core, Disc core, T core, and many more, mainly distinct in shape. This factor alone can contribute to changing the properties of the core, making some types more suitable for one application and some for another. Why Use Amorphous Cores?Once you have gone through all the applications, let's now have a look at the key reasons why you should consider using Amorphous Cores!Reduced Core LossCore losses are referred to as the dissipation of energy in the form of heat when the core is exposed to alternating magnetic fields. Amorphous Cores are found to have relatively lower core loss depending on their structural properties. However, you can use them for optimal energy efficiency, especially in applications involving continuous processing. Broad Frequency RangeUnlike the typical magnetic or crystalline cores, these have a broad frequency range. They aren't limited to the specific frequency bands. These are the main reasons why amorphous crystalline cores are considered versatile in multiple applications. Reduced Carbon Dioxide EmissionAccording to the analysis shared by the United Nations, transformers alone contribute to the overall carbon dioxide emission significantly. Their fair share in the emission is around 730 million tons per year. Owing to the energy efficiency of the Amorphous Cores, you can significantly reduce your industry's carbon footprint by minimizing the production and emission of carbon dioxide. Noteworthy Initial PermeabilityAnother important aspect is the considerable initial permeability offered by the Amorphous Cores. They are pretty sensitive to mere magnetic field changes. This property is helpful in inductors, sensors, and transformers where swift magnetic flux changes must be accommodated. 10 Most Common Applications of Amorphous CoresAmorphous Cores are made to be used in diverse applications owing to their low connectivity, low loss, and higher vulnerability. Some of the most common applications of their usage include:1. Audio SystemsAmplifiers are undoubtedly a key component of any audio system, and Amorphous Cores, in turn, are important components of amplifiers. These are mainly involved in amping up the received signal and submitting it to the speaker or any other output source. By amping up, we mean increasing the signal amplitude, so you can observe a significant increase between input and output signal amplification. How much an amplifier amplifies the signals depends entirely on the gain, i.e., the ratio of output specifications, like current and voltage, to that of the input. 2. Power SuppliesSoft magnetic material is usually preferred in power supplies. A power supply is a source electronic device that transforms any form of energy into an electrical one and supplies it to an electric load as output. Its function revolves around converting the received energy form, mostly the current itself, into the required frequency, current, and voltage to power the entire load side. 3. Medical EquipmentWhen it comes to medical equipment, safety stands as a key factor to consider. That said, amorphous materials are a noteworthy combination with Toroidal core, C-core, or Black core. 4. Magnetic SensorsThese cores are also used in magnetic sensors like position, magnetic field, and current. Their high sensitivity to any magnetic field change around them makes them ideal for the purpose.5. TransformersAnother important application of the Amorphous Toroidal core is distribution and power transformers. With them, you get to enjoy higher efficiency and minimized core loss. On the other hand, typical solutions, like silicone steel cores, won't only cost you a lot but also have reduced efficiency and increased power loss due to heat generation. System heating remains another incurable issue. 6. Current TransformersYou can also use these cores in current transformers to precisely measure the distribution systems' electric currents. Their extent of accuracy and the linearity of performance over increased and decreased temperature makes them suitable for this application. 7. Magnetic ShieldingTelecommunication equipment and medical devices need magnetic shielding for safe and accurate working. Amorphous Cores can provide this shield against electromagnetic or radiofrequency interferences. 8. Noise FilteringNoise can be disturbing or disrupting, affecting the output signal and reducing its reception on the receiver side. However, with the noise filtering power of the amorphous chokers installed in chokers and inductors, you can ensure to get rid of these unwanted disturbances. 9. EV ChargingElectric vehicles will take over the world in the coming years. Every vehicle will get replaced by its EV version, and so will the need for EV charging will arise. What sets them apart from other cores is their ability to minimize the core losses and save as much power as possible. 10. Pulse TransformerHigh-speed and in-time communications demand precise time management with minimum disturbance and pulse shaping. This task can be done well by the Amorphous Cores, which ensure swift transmission and resistance against distortion.Difference Between Amorphous and Non-Crystalline Cores?Now that you have explored the key applications of the amorphous solids' let's have a look at the key differences between the amorphous and nanocrystalline cores!Undoubtedly, both competitors are used diversely in applications; both are structurally opposites. One consists of well-defined crystalline forms, while the other is completely non-crystalline on the nanoscale level. But that’s only the structural aspect, other differing points include:1. Magnetic CharacteristicsAmorphous Cores tend to have higher initial permeability, quickly responding to minimal changes in the magnetic field. So, you can find them ideal in magnetic sensing. On the other hand, nanocrystalline cores have higher permeability throughout their work, so these are ideal for usage in highly sensitive sensing. 2. FrequencyNanocrystalline and Amorphous Cores have high-frequency applications, but the former is often considered the best pick. It's because nanocrystalline cores are the advanced version of cores that have revolutionized the industry with their exceptional perks and features, as they combine both the specs of amorphous and crystalline cores. 3. ApplicationAmorphous Cores find their applications in noise-filtering inductors, power transformers, distribution transformers, etc. The nanocrystalline cores work more effectively in the inductors for power electronics, high-frequency transformers, etc. Where to Find the Best Amorphous Cores?The next question in your mind must be where to get the best Amorphous Cores from.
