Special transformers

Our special transformers

Some requirements fall outside our standard ranges: a distribution substation, a building where oil is not wanted, a machine that needs a specific supply. Our special transformers:

• H59 / H61 oil-immersed transformer: a three-phase MV/LV distribution transformer for a ground-mounted (H59) or pole-mounted (H61) substation, on request.
• Cast resin dry-type transformer: an MV/LV transformer whose windings are encapsulated in epoxy resin, with no liquid, on request.
• Three-phase transformer for HP printers: for HP Indigo digital presses, from 25 to 125 kVA, with a price shown for each power rating.

For low-voltage applications with voltages or a power rating outside our catalogue, our custom-built transformers can be configured online, with the price displayed.

Oil-immersed MV/LV transformers: H59 and H61

An MV/LV transformer steps the medium voltage of a distribution network down to the low voltage used on site: 400 V between phases and 230 V between phase and neutral. In the UK, the same unit is often called an HV/LV transformer.

The H59 and H61 are oil-immersed three-phase transformers: the H59 is ground-mounted, inside a substation; the H61 is mounted on a pole. Both are available on request: tell us the network voltage, the output voltage, the power rating and the type of substation.

Cast resin dry-type transformers

In a cast resin transformer, the windings are encapsulated in epoxy resin and cooled by air: there is no oil, and therefore no risk of leaks. It is often chosen for a substation inside a building. We offer it on request, based on the network voltage, the power rating and the enclosure you require.

Transformer for HP Indigo presses

Our three-phase transformer for HP printers supplies HP Indigo digital presses: input 3 × 410 V, output 3 × 400 V with neutral, in 25, 40, 75, 100 or 125 kVA depending on the press. It is supplied in an IP23 ventilated enclosure, with terminal block connections. Like our low-voltage three-phase transformers, it is wound and tested in our workshop in Gailhan. Tell us your press model and we will confirm the right power rating.

Requesting a special transformer

For an accurate quote on a special transformer, dedicated or custom-built, please tell us:

• the input and output voltages, single-phase or three-phase;
• the power rating, in VA or kVA;
• the installation: indoors or outdoors, the IP rating, the space available;
• the options: tappings, vector group, thermal protection;
• the quantity: a one-off or a batch.

To replace an existing transformer, include a photo of its rating plate and its dimensions. Request your quote: we reply within 48 h. At low voltage, a custom-built transformer takes 48 h to one week to manufacture, depending on the power rating.

A transformer manufacturer in Gailhan since 1993

ABL Transfo has been making transformers since 1993 in Gailhan, in the Gard, between Nîmes and Montpellier in southern France. Our low-voltage single-phase and three-phase transformers, our toroidal transformers and our autotransformers are wound and 100 % tested there. For a 400 V machine, see also our three-phase transformers. For professionals, a trade account shows prices excluding VAT with a 5 % discount, and white-label supply is possible.
