Valves & oil handling
Throttle, ball, gate, drain, sampling and Buchholz-connection valves.
Solutions / ARES Trafo / Transformer components
Start with the interface—not the product name.
ARES supplies a broad transformer-component portfolio. TM Networks focuses the RFQ on drawings, DIN / EN interface, material, seal, operating condition and documentation—especially for transformer valves.
Portfolio overview
Transformer components across protection, cooling and assembly.
The full ARES range is too broad for a single catalog page. TM Networks screens the required category after receiving the drawing, bill of materials or functional specification.
Protection
Pressure-relief valves, Buchholz relays, breathers and protection accessories.
Indication & cooling
Oil-level indicators, axial cooling fans and dry-type cooling fans.
Mechanical & electrical
Bushings, wheels, terminal boxes, metal fixing parts and flexible copper connectors.
DIN valve focus
Two DIN families to start the technical conversation.
Use the official product pages for current manufacturer detail and send TM Networks the project drawing for fit, options and quotation review.
Oil drain device
The official ARES page lists NW22, NW31 and NW40 versions. Selection must be checked against transformer size, connection arrangement and drawing revision.
