Transformer Coil) Hydraulic Pressing Machine

The Transformer coils are designed for a specific Winding Length. Length of the winding increases due to the gap in each disc. In order to maintain the length within the design parameter, the coil shall be pressed by applying the designed or specified pressure.

The machine is specially designed for transformer coil (big, medium and small) pressing. It is an essential machine for transformer production, particularly for power transformer above 110KV.  

Features:

1.Window height is adjusted by motor. Digitally display pressure and coil height.

2.One big hydraulic cylinder up Stroking; advanced and stable hydraulic system.

3.With motorized trolley, it is very easy for coil transport.

4.With PLC and Touch Screen.
