Laminated Wood Stepped Blocks for Transformer
Transformer pads and ladder pads are widely used for insulation and support in transformers and transformers. It is made of low dielectric loss Electrical Laminated Wood according to the requirements of customer drawings. It has moderate specific gravity, high mechanical strength, good insulation performance, easy vacuum drying, good compatibility with transformer oil, and dielectric constant close to transformer oil Mechanical processing and other advantages can be used for a long time in 105 ° transformer oil.
