INTRODUCTION
Transformers are devices that use electromagnetic induction to transfer electrical energy between two or more circuits to increase or decrease alternating voltages in electric power applications. These devices are primarily composed of a laminated magnetic core and windings wound over it that are both insulated from the core and one another. Different types of transformers are available in the present market. You must select the best transformer for the job based on where and how it will be used. To learn more about and obtain the best transformer for your application and purpose, contact Vajra Transpower, it is a leading transformer-making company in India, which not only provides a wide range of high-quality devices but can also assist you in customizing your transformer. This blog will provide general information about the various types of most commonly used transformers based on various parameters.
Core Based
Transformers are classified into core and shell types based on their core. Core-type transformers have a rectangular core with windings wrapped around the core’s limbs. The frame’s limbs have half primary and half secondary windings, which reduces leakage reactance. In addition, low-voltage windings are placed inside high-voltage windings to reduce high-voltage winding insulation requirements. Shell-type transformers, on the other hand, have three limbs in the core: one central and two side limbs. The windings are wrapped around the central limb in this configuration, with the high-voltage windings sandwiched between the low-voltage windings. Considering the disadvantages and advantages of both these types of transformers, the core type of transformers is more widely used.
Application Based
Step-up transformers and step-down transformers are the two basic types of transformers classified according to the application. Step-up transformers raise the input voltage to a higher voltage level, whereas step-down transformers lower the input voltage to a lower voltage level. This is the primary distinction between these two types of transformers. This means that the step-up transformer’s input voltage is low, with the secondary winding being the high voltage-low current winding and the primary winding being thick insulated copper wire (and just the opposite for step-down transformers). Power plants, microwaves, and X-ray machines all use step-up transformers. In doorbells and voltage converters, step-down transformers are used.
Vajra Transpower is a leading step-up and step-down transformer manufacturer in Hyderabad.
1. Number of Phases Based
Single-Phase Transformers:
Single-phase transformers are essential for achieving voltage transformation in residential and non-industrial areas. With only one main and one secondary winding, they efficiently cater to smaller clients’ electricity needs.
Three-Phase Transformers:
In contrast, three-phase transformers, crucial for high-density power demands, utilize three windings rotated through a magnetic field. Proper connection of these windings ensures effective power distribution in industrial settings and large-scale facilities.
2. Vajra: Transforming Power Supply
Vajra stands as the premier power transformer supplier in Hyderabad, excelling in quality and application-specific distribution transformers. Our product range includes oil-cooled transformers, OLTC distribution transformers, and efficient dry-type transformers.
OLTC Distribution Transformers:
Primarily deployed in heavy industries like chemical plants and steel mills, OLTC transformers from Vajra offer precision and reliability for demanding applications.
Dry-Type Transformers:
Designed for indoor use, our dry-type transformers (ranging from 40 KVA to 1250 KVA) incorporate advanced cooling through an air ventilation system, addressing diverse power needs.
Distribution Transformers by Vajra:
Vajra’s distribution transformers exhibit low impedance, ensuring superior voltage regulation and minimal flickering, especially under major motor loads. These corrosion-resistant units, with stainless steel bases, require no additional cooling arrangements and are self-cooled with cooling oil.
Vajra examines the client’s entire requirement set, and our expert industrial technologists will recommend the best option for you. Numerous transformer manufacturers in Hyderabad can assist you in selecting electrical equipment such as transformers or other power management solutions.
