Description

Products Description

Electric laminate wood have been widely used in oil-immersed transformers to make upper and lower pressure plates, lead brackets, iron yoke pads, and other parts, and are used to make clamps in transformers.

It replaces steel plates, insulating cardboard, and epoxy cardboard, The application of epoxy glass cloth panels in these aspects reduces the weight and material costs of the transformer.

Electrical laminated wood boards are veneers made from high-quality birch wood that is steamed, peeled, and dried. They are coated with special insulating glue and processed under high temperatures and high pressure.

Product advantages:

1.Good insulation performance

2. Good heat resistance

3. Good corrosion resistance

4. High mechanical strength

5. Strong plasticity

Packing

Packaged in wooden crates, wooden framed cases or other strong enough materials covered with moisture-proof materialoutside.

Gross weight of each package not exceeds 3000kgs.

Storage

Electric Laminate Wood should be stored in a clean and dry room with temperature not exceeding 40℃ and should be laid flat wise on a stepping-board which is at least 50mm from the ground, never close to fre source, heat source and protected against moisture.

Application scenarios

Electric Laminate Wood is widely used in all aspects of power systems. In cable manufacturing, insulating cardboard is often used as the insulation layer of cables to effectively isolate conductors and prevent current leakage.

In transformers, insulating cardboard is used as the insulating material of oil-immersed transformers to ensure the safe operation of the transformer. In addition, insulating cardboard also plays an indispensable role in the insulation structure of power equipment such as switchgear, motors, and generators.
