Transformer cellulose-based pressboard

Insulation paper is composed of fiber, is a very hydrophilic material, with hygroscopic, its moisture content with the environmental temperature and humidity change and change, and the cardboard water content has a great impact on the cardboard performance, because the customer must consider the characteristics in the use process:

1. Within a certain range, the tensile strength of cardboard with cardboard water content enhancement and decline.

2. Within a certain range, the cardboard elongation increases with the cardboard water content.

3. cardboard expansion rate with the increase of cardboard water content and increase, but the three directions of cardboard (longitudinal, transverse, thick to) the degree of influence is not the same, so in the determination of cardboard processing precision geometry size must be considered cardboard water content change to the impact of the size.

With good dielectric properties, high heat resistance and mechanical strength, mainly used in the manufacture of laminated products and in the motor, instrument, transformer, reactor, mutual inductor and so on

Used in equipment as insulating material.
