Variable Transformers

Variable Transformers are utilized in commercial applications that require varying amounts of voltage. This type of system is able to produce different levels of power from a single input. Unlike standard transformers, variable transformers only feature a single coil. The voltage and load are not separated. Since these types of transformers only include a single coil, they are not useful for certain types of projects.

Step-Up Transformers

A step-up transformer is a type of system that produces a high output voltage from a low-input voltage. This type of electrical transformer is utilized to process the voltage from the alternator in transmission lines. Step-up transformers are also utilized by electric motors, x-ray machines, microwave ovens, and power plants.

Step Down Transformers

Step-down transformers feature both primary and secondary coils. The primary coil features more turns of wire when compared to the other coil. This causes the voltage in the secondary coil to be reduced. Step-down electrical transformers are used to reduce output voltage levels. This type of electrical transformer is used in hardware such as televisions and inverters. Step-down transformers are also utilized at distribution substations.

How Does a 3 Phase Transformer Work?

The 3 phase electrical transformers for sale on our website are utilized in advanced commercial applications that require massive loads and power distribution because of the financial benefits.
