Ultra Isolation Transformer

Servomax Limited is the leading company in being the best manufacturers, suppliers, and exporters of ultra isolation transformers which are significant models of isolation transformers. Dangerous surges, transients, spikes, and RFI noise are always evident with most of the AC power lines. Our ultra isolation transformers are the best solutions for such noises.

Switching noises may arise from capacitors, ACBs, MCCBs, large motors, overhead cranes, elevators, presses, etc. In addition, switching of the transistors, thyristors, and relays also cause electrical noise. When the frequency of such noise exceeds higher frequency, many disruptions like untraceable data errors, memory loss, change of programme, erratic machine behavior, and others may arise. Servomax Limited’s ultra isolation transformers eliminate such noise as they are designed with stringent reliable measures. The capacities of our ultra isolation transformers are available till the range of 3000kVA.


Here are the different purposes where our ultra isolation products are used.

  • Computers and Peripherals
  • CNC Machines
  • Digital Communication Telemetry Systems
  • Industrial Machinery
  • Medical Instrumentation


Servomax Limited offers high-quality ultra isolation transformers possess these magnificent benefits.

  • Reduced noise with the use of high-insulation materials and special shielding techniques
  • Specialized core designs which enable blocking of higher frequencies
  • High protection against impulse noise, bus short-circuit, accidental discharge of capacitors, strong lightening, and so on
  • Prevents damage of microprocessor-based instruments and equipment
  • Availability of air-cooled and oil-cooled models
