Isolation Transformer Manufacturer

The Isolation Transformers with varied Input & Outputs (different ratios) are provided with suitable enclosures fitted with switchgear or meter/indicator fuse etc. These are available in aluminum windings also.

3 Phase Galvanic Isolation Transformers

Our 3 phase Galvanic Isolation Transformers are used to supply isolated power to machines, and CNC machines where step-down voltages are required. Robotic controllers are also required such three phase supplies of 50 or 60 Hz.

Many electronic gadgets, robotics, CNC Machines, SPMs UPS systems require “Clean” Power. Those could get damaged due to input harmonics or spics and surges. Our isolation transformers minimize the input “noise” and provide “better power” to output. “Electrostatic Shield” is provided between input & output. Since this shield is grounded to earth, the noise is sent to the ground and clean power to output.

Necessary ducts/wedges are provided for cooling of conductors, between pri & sec windings and also between windings & core. High voltage, up-to 2.5 kv insulation is maintained between windings and core also. each every transformer is tested for h.v. breakdown, megger tests, along with nlc, core loss test and voltage ratio test is conducted to assure best performance.

3 Phase Galvanic Isolation Transformer

We manufacture and supply these types of transformers with or without enclosures. Various taps at input side like, 380--400---415--440 v, (delta/star) & at output side 400 –415v (star/delta) are generally given. For robotics and CNC machines/servo drives, input 415v delta and output 200 or 220v star configurations are used /asked. Primary and secondary may have different taps to provide exact voltage requirement at sites.

We always check and confirm the quality of our products on different parameters, before handing over to customers, so they never get disappointed by supplies for their quality and our after sale service as well.

Our three phase Galvanic Isolation Transformers are

  • Easy to install and operate
  • Superior quality
  • Having a long working life
  • Highly durable in nature
  • Affordable price
  • True in Capacity (ratings/voltage)

We can manufacture following type of Isolation Transformers

  • Suitable Powder Coated steel fabricated Enclosures
  • With OR without wheels, lifting I-Bolts.
  • With/without Meters and Switchgear
  • Exhaust fans for maintaining temperature

Ultra Isolation Transformers

Spikes generated on switching of electrical utilities (like, Motors, VFDs, UPS Systems, PCs, Rectifiers, Battery Chargers, Lighting Loads, and Air Conditioners etc.) in Industrial & Commercial environment can damage Precision Instruments, Micro-processors, or other active electronic devices. During switching of all these, High Voltage (up to 6000 V) & high frequency power line Noises are produced from spikes which interfere with Digital-Electronic equipment causing change in program, erratic behaviour, data corruption, loss of memory etc.

Ultra Isolation Transformers eliminate noises from high frequency and attenuates the spikes to negligible values. This way these protect from such kind of electrical disturbances. Transfield supplies ultra-isolation transformers in single or three phase systems up to 100 KVA.
