Laminated Wood Boards

1. Brief induction of laminated wood board

1) Low dielectric loss electrical insulating laminated compressed wood is widely used as insulating and
supporting material in power transformers and instrument transformers .It has many virtues such as moderate density ,
high mechanical strength ,easy to dry in vacuum dryer ,no bad inter-reaction with transformer oil ,easy to mechanical
processing etc. The dielectric constant of this materials close to transformer oil ,that make a reasonable insulation
match .It can be used in transformer oil of 105 centigrade for long time.

2) People usually use this material to make upper / lower pressure pieces ,cable supporting beams,limb spacer block
in oil-immersed transformers.And clamps in instrument transformers.It substitute steel plate ,insulating paper sheet ,
epoxy paper sheet ,epoxy glass fiber woven laminated board in these field ,thus can down the fabricating expense and weight of transformers.

3) Electrical insulating laminated compressed wood is made from birch and willow veneer that peeled from high
quality timbers ,Veneer was and copressed with high temperature after gelatinizing .

2. Standard dimension of our laminated wood board(unit mm)

1) To meet customers needs we produce boards of three different area :

1500×3000  1220×2440   850×1850

2) Usual thickness: Roechiling can also produce board of special thickness on customer’s requests.

10, 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 100
