Oil Cooled Transformers

One of the products in AEI's repertoire are specialized oil-cooled transformers, the applications of which include smelting scrap iron, refinement of steel, etc. These transformers use transformer/insulation oil as a cooling/heat dissipation medium, and they boast a much higher rate of efficiency at an economical price as compared to their air-cooled counterparts. Our catalogue of oil cooled transformers includes furnace transformers, solar transformers, wind transformers, dual primary & secondary transformers, etc. all up to 2.5 MVA.

Rectifier Transformer

For minimal ripple effect and voltage drop, AEI also brings to you the rectifier transformer under the special application transformer category. We manufacture an array of rectifiers with both, three phase and six phase transformers being a part of our product line. Along with this, we use premium quality diodes and thyristors in the same tank in order to provide our customers with an efficient work rate from the transformer.

Isolation Transformer

The very modernly designed isolation transformer from AEI has a core with ingenious properties which exhibits sufficient leakage inductance to minimize noise with a proper transfer of fundamental properties. Moreover, this product uses a split winding construction as bifilar corrections in order to reduce the looping capacitance of winding along with a shielded enclosure which totally blocks electronic noise and minimizes static charges as well as R.F. noises. Our isolation transformer basically has a special capability to create a separately derived source to combat current loops in order to eliminate unnecessary common mode noises.

High Current Source

In addition to our high voltage breakdown testers, AEI also manufactures high current source testers, which test for high current sources up to 10000 Amperes for current testing in transformers. Our testers are specifically designed to maintain a negligible drop in voltage irrespective of high current. Our testers are outfitted with all of the standard safety measures in the event of overloads, short circuits, earth faults, etc. All of these factors combined make our high current source testers very accessible and easy to use.

Control Transformer

From the wide range of transformers that we have to offer from our catalogue, our ingeniously designed control transformers are used to step down or even step up the voltage to power the control devices of a circuit or machine be it residential heating and cooling devices or control panels. Along with providing a safe working environment, our transformers deliver top notch service and efficient working by catering to all your requirements and needs.

Neutral Grounding Transformer

AEI manufactures state-of-the art neutral grounding transformers, which are made using a combination of single-phase grounding transformers and neutral grounding resistors (NGR). These transformers are used as a precautionary measure to reduce the likelihood of damaging short-circuits in the winding of generators, alternators, and power transformers, so you can rest easy knowing your equipment is in safe hands. Our NGTs will limit the magnitude of any transient voltage during ground faults, and will provide a source of ground fault current during any line-to-ground faults.

High Voltage Breakdown Tester

AEI manufactured quality high voltage breakdown testers apply a high voltage across a specimen of insulation under test through a high voltage transformer making them ideal for carrying out high voltage breakdown tests in any work environment. Due to the rich raw materials that we use to manufacture our products, our testing units are more than flexible enough to work like an absolute charm in all kinds of work spaces.

Milli Volt Drop Kits

Our product line also boasts advanced modern millivolt drop kits which are offered in a wide variety of technical configurations to meet the testing requirements of clients. Our testing kits can be invaluable in finding current loads that may be contributing to drainage of batteries. This is accomplished by measuring the drop in voltage across the fuse, which protects the circuit. These kits will prove to be indispensable for manufacturers of transformers and switchgears.

Transformer Testing Panel

We use state of the art raw materials to manufacture our modern and customizable transformer testing panels which carry out various tests such as open circuit tests, short circuit tests, DVDF tests, HV tests,etc.as per your requirements with optimum work rate and efficiency. AEI manufactured modern testing units are very user friendly with all the controls being panel mounted to ensure maximum accessibility and ease of use.

Demagnetizer

The demagnetizers of AEI make have the ability to produce strong alternating current inside the window, where work pieces are passed through to remove magnetism from these pieces. Moreover the superior technology used at AEI allow s our demagnetizers to be both, powerful and efficient at the same time in order to remove magnetism from materials such as die steel, spring steel, high speed steel, bearing steel and mild steel. We are flexible when it comes to living up to your needs and that’s why our demagnetizers come in various sizes and specifications, from being used for inline production process to fitting a roller conveyer from inside the window for continuous operation in production.

Induction Heater

Our revolutionary induction heaters are indispensable for heating applications of bearings, gears, motor housings, sleeves and couplings. Our heaters are especially invaluable for fitting bearings in a non-destructive manner. For this purpose all our induction heaters are outfitted with digital non-conductive thermal sensors and automatic cut-off timers to ensure the equipment's safety in any circumstance. Another safety precaution that our heaters utilize are auto-demagnetizer circuits and the usage of high frequency flux to prevent any unwanted demagnetization.

Special Electrical Items

Beyond the products listed on the brochure, AEI furthermore offers manufacturing and repairing services for any special electrical items as per the needs of our clients. These services extend to products including but not limited to relay test kits, inductors (choke), soldering instruments, current and potentials transformers.
