TTGW

TTGW

Isolation transformer.

Features

Dry type transformer

All transformers are dipped in anti-flash varnish for increased insulation and compactness.

Reduces long-term operating costs.

Low temperature rise.

Longer life than standard transformers.

Prepared for higher ambient temperatures.

Low connection peak.

Lower noise level.

Safety class I

Includes lifting eyebolts

Metalic box IP-23 enclosure painted with Polyester resin RAL 7035 (cat. C4 ISO 12994-2)

Possibility of tailor-made manufacturing

Applications

  • Circuit isolation, with the possibility of increasing or reducing the voltage.
  • Reducing voltage drops in installations with long cable lengths. With the installation of a step-up transformer and a step-down transformer.
  • In installations with a certain level of electrical noise, the TTG series helps to improve the electrical network quality in secondary.
  • Changing the neutral system of an installation
  • In installations where energy savings is critical, or where a lower connection peak is required such as renewable energy plants or high energy efficiency installations.

Available accessories

  • Protections in primary and secondary.
  • One, two and up to 3 electrostatic screens.
  • Class II
  • Wheels.
  • PT100, PTC or Bimetallic probes.
  • Painting C5.
  • Different RAL.
  • Temperature control unit
  • Anti condensation system
  • Different IP up to IP-65
