Step-up and step-down three-phase isolation transformers
POLYLUX presents the new range of Three-phase Isolation Transformers TTU and TTD, designed for continuous operation at maximum output 365 days a year. This guarantees power is supplied to the installation or equipment they supply.
Definition and applications
The main application of the TTU transformers is the isolation of circuits, with the possibility of increasing the voltage from 230V to 400V.
The main application of the TTD transformers is the isolation of circuits, with the possibility of reducing the voltage from 400V to 230V.
In installations with a certain level of electrical noise, the TT series helps improve the electrical network quality in secondary.
Changing the neutral system of an installation.
Manufacturing characteristics
All the transformers are dipped in anti-flash varnish and then compacted in the furnace. This process increases the insulation grade, reduces noise and provides anti-moisture, waterproofed protection.
All the connection terminals are made of cooper. 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.
The high-power transformers are manufactured with format cores and low loss properties, thus contributing to improving performance.
All the transformers are checked automatically one by one and the compliance test report is created accordance with the corresponding standard.
