Effect:
Support and fixation: Between the transformer windings (coils), oil passage supports act like a "skeleton" to separate and fix the windings in the correct position, preventing displacement or deformation due to electromagnetic forces during operation.
Forming oil channels: The struts leave gaps between the windings, which are the flow channels for transformer oil. Transformer oil circulates in these oil channels, taking away the heat generated by the windings and achieving cooling.
Insulation: The oil duct support itself is made of insulating material, which can effectively prevent short circuits between windings and is an important component of the transformer insulation system.

Product Features:
Good flame retardancy, insulation properties, and high electrical strength; Low water absorption rate, good moisture resistance, good dielectric resistance, good mechanical strength and processability. The appearance color of the board is uniform.
By applying new processes and equipment, potential issues such as bubbles, delamination, and embrittlement in laminated boards have been avoided. Single board made by steaming, rotary cutting, and drying, coated with special insulation adhesive, and then made by high temperature and high pressure.
