Wholesale Electrical Laminated Wood
The raw materials of electrical Laminated Wood are high quality birch and willow timbers. After boiling, rotary cutting, drying, these timbers are made to veneers. At last the veneers will be glued with special insulating gluewater and processed under high temperature and pressure.
People usually use this material to make upper/lower pressure pieces, cable supporting beams, limbs, spacer blocks in oil-immersed transformers, and clamps in instrument transformers. It replaced steel plates, insulating paper sheets, epoxy paper sheets, epoxide woven glass fabric lamination in these fields, and cut down the material expenses and weight of transformers.
Application:
It is widely used for production of power transformers as high electrical insulation material, like Pressure Beams, step blocks, pressure spare parts, top and bottom support coils, potential rings, pressure rings , spacers, etc. For his mechanical strength, laminated wood can be also use for many applications as abrasion resistance material under stress.
Laminated Wood Features:
· Good electrical insulation
· Excellent oil absorption
· Low density
· High mechanical strength
· High and low temperature resistance
· durable
Identify the main points:
Different applications require the selection of materials of different brands.
