Electrical laminated wood is an essential insulation and supporting material widely utilized in transformers and instrument transformers. It boasts exceptional mechanical strength and superior compatibility with transformer oil, capable of long-term operation in 105ºC transformer oil environments.
Commonly used for pressure plates, spacer blocks in oil-immersed transformers, and clamps in instrument transformers, this material serves as an efficient replacement for steel plates, insulating paper shells, and epoxy paperboards. This substitution significantly reduces both the overall weight of the transformer and material costs.
Premium Raw Materials: Crafted from high-quality thin veneers of birch, stained wood, and other premium timber. The product is treated with specialized insulating glue and processed under high-temperature and high-pressure conditions to ensure maximum durability.
