Reactors are an indispensable part of the power system and play an extremely important role. The insulating materials used are naturally sloppy. What are the unique properties of FR-4 epoxy board as the commonly used reactor insulation material? FR-4 epoxy board is also known as epoxy glass cloth laminate, which is very common in insulating materials. It is made of electronic cloth immersed in epoxy phenolic resin and other materials after high temperature and high pressure hot pressing. Laminates have strong machinability, dielectric properties, high temperature resistance, moisture resistance and other properties.

The reactor chose FR-4 epoxy board as its brilliant material, which is inseparable from its performance characteristics. First of all, its high temperature resistance, electrical equipment will heat up after a long time of work, if the material’s high temperature resistance is not good, it will make the machine malfunction, and
will accelerate the aging of the material. The FR-4 epoxy board still has high mechanical strength at a normal temperature of 150 ° C, which can better protect the reactor. At the same time, it also has excellent dielectric properties. Since charged objects are prone to generate magnetic fields, resulting in the formation of electric
current, it is necessary for the dielectric properties of materials. The relative dielectric constant of the FR-4 epoxy board is ≤ 5.5; it will not be broken even under high pressure.

Super moisture resistance is also a characteristic of FR-4 epoxy board, because its water absorption is very small, so that even if it is used outdoors all the year round, wind and rain, its performance will be very stable. Moreover, the raw material of FR-4 epoxy board is imported, and with advanced processing technology, the quality is absolutely guaranteed, so it is used on the reactor, you don’t have to worry about it.
