Product Introduction
Effect:
The upper and lower pressure plates, lead brackets, iron yoke pads, and other parts used to manufacture oil immersed transformers are used to make clamps in transformers, replacing the application of steel plates, insulation cardboard, epoxy cardboard, and epoxy glass cloth boards in these areas, thereby reducing the weight and material costs of transformers.

Product Features:
The laminated wood used for electricians is mostly made of Northeast birch wood, which is impregnated with insulating resin and heat laminated. It has a moderate specific gravity, is easy to vacuum dry, has good compatibility with transformer oil, and is easy to machine. Its dielectric constant is close to that of transformer oil, and the insulation coordination is reasonable. It can be used for a long time in transformer oil at 105 ℃. Electrical laminated wood, also known as electrical laminated wood or phenolic laminated wood, is a composite material made of multiple layers of high-quality wood thin sheets pressed under high temperature and high pressure with phenolic resin adhesive. Its biggest feature is that it combines the mechanical strength of wood with the excellent insulation properties of phenolic resin.
Why use laminated wood?
Good insulation performance: Wood itself is a good insulator, and after special treatment, its insulation performance can meet the requirements of transformers in oil immersed environments.
High mechanical strength: The lamination process gives it high bending and compressive strength, which can withstand the mechanical stress and vibration inside the transformer.
Lightweight and cost-effective: Compared to metal materials, laminated wood greatly reduces the weight of transformers and lowers material costs.
Oil and heat resistance: It can work stably in transformer oil for a long time and has a certain degree of heat resistance, meeting the heat resistance requirements of transformer insulation materials.
