Custom tile URL. What type of layer should I use?

[AndreyLabodin]

Hello.
I have a source of tiles with the following URL format:
http://tiles.XXXX.com/map/lv10/00/000/000/616/000/000/700.png?key=XXXXXX
I know how to work with that kind of URLs with OpenLayers, but I can't find a way to make it with ArcGIS API for Javascript.
The tiles are in World Mercator spatial refference (EPSG:3395)
Should I use the WebTiledLayer or something else?

That is how it's done with OpenLayers:
