Application of FR4 epoxy insulating glass fiber board

The insulation board is a composite material produced by combining glass fiber cloth and epoxy resin. This material has very good insulation performance, ultra-high hardness, excellent corrosion resistance and ultra-high flame retardancy. It has been widely used in many occasions.

What fields will the insulation board be used for?

The common insulating board mainly uses its own "insulation" performance to be applied in some electrical equipment, conductors, and electromagnetic circuits. It is widely used in power systems, such as the application in transformers. With the development of high and low, insulation boards are widely used in high-speed rail. Generally speaking, insulation boards are applied to power generation equipment, power transmission equipment, communication equipment, new energy industries, and in the fields of electronics, electrical appliances, and motors.

Why are insulation board insulation materials used in these fields?

Here we take the common applications of power generation and power transmission as an example, such as pollution flashover of insulators, aging and breakdown of coil insulation of generators and power transmission system equipment, and breakdown of transformer coil insulation at multiple voltages. These are the main causes of power system failures and blackouts. Good insulating materials, in use, can greatly avoid the above situation, and maintain and ensure the stable transmission of power.

How to Improve the Quality of Insulation Boards to Meet Market Demands

With the development of the country, the power system develops from the original low voltage to high voltage, and the power transmission develops from short distance to long distance, which has stricter quality requirements for the insulating materials used. In addition, with the ultra-high-speed development of China's high-speed rail in recent years, this convenient insulating material requires a variety of stable, safe and customized special insulating plates with special functions.

In order to meet the needs of the market, the direction of developing insulation boards is mainly focused on: high voltage resistance, impact resistance, corrosion resistance, water resistance, turbidity resistance, cryogenic resistance, radiation resistance and ultra-high flame retardancy.
