TTG SERIES

POLYLUX’S TTG SERIES

High performance three phase ecological transformers

The TTG series is made up of three-phase ecological isolation transformers. They are specially designed to provide high performance, being able to work continuously and at maximum performance 365 days a year, as well as having lower losses than a standard transformer.

This high performance offers a great reduction in operating costs and provides great energy savings, helping to protect the environment.

This series is made up of isolation transformers with 400V three-phase input and output that have a rating range as from 0.63kVA up to 1000kVA.

We can find different versions depending on their degree of protection:

  • TTGX: IP00
  • TTGW: IP23
  • TTGZ: IP54/65

Some of its utilities:

  • Change the neutral regime of an installation.
  • 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.
  • 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.

Construction features:

  • All the transformers are dipped in anti-flash varnish and then compacted in the oven. This process increases the insulation grade, reduces noise and provides anti-moisture, waterproof protection.
  • All the connection terminals are made of copper. For transformers with aluminium coils, internal bimetallic AL-CU connections are made by welding with filling and sealing material to ensure a safe, long-lasting connection.
