TTFKW series three-phase isolation transformer for three-phase networks with high levels of harmonics. These “k” factor three-phase transformers are used to resist overheating produced by non-linear load harmonics.
A k=13 factor transformer is used where the harmonic load represents 30% of the total load.
A k=20 factor transformer is used when the harmonic load represents 60% of the total load.
All transformers are dipped in anti-flash varnish and then pressed in a furnace. This process increases the degree of insulation, reduces noise and provides moisture and waterproof protection.
All connection terminals are made of copper. For transformers with aluminum coils, internal bimetallic AL-CU connections are made by welding with filler and sealant to ensure a secure connection over time.
Models with different “k” values can be produced upon request.
All transformers are automatically tested one by one and the compliance test report is generated according to the appropriate standard.
