TTW

TTW

Isolation transformer.

Features

Dry type transformer

Anti-flash varnish finish, offering:

  • Protection against corrosive environments.
  • Increase of electrical isolation.
  • High compression capacity.
  • Reduction of noise level.
  • Increase of productʼs lifespan

IP-23 enclosure, metal enclosure painted with polyester resin RAL 7035 (cat. C4 ISO 12994-2).

Safety class I.

Includes lifting eyebolts from >10 kVA.

Possibility of tailor-made manufacturing.

Applications

  • TT transformers are used for insulation galvanic three-phase installations for reasons of security.
  • They are also used in the generation of neutrals referenced to ground in single-phase installations of high power.
  • In facilities where there may be small peaks of voltage or noise, the TT transformers help improve the quality of the signal that feeds the charges.
  • On the other hand in facilities where there may be several leakage to ground, TT transformers ensure the supply avoiding the tripping of the differential switch general.

Available accessoires

  • 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
