Insulation board, many of us have contact in daily life, but don’t know what kind of insulation board is. Insulating board can guarantee our safety in some special working environment. What material is it?

Insulation board properties

Insulating boards have different physical properties because of the different materials used. The main insulation board functions are also related to the materials we use. Common materials include: PVC board, epoxy board, paper offset board , Cloth offset, plywood, various resin boards, etc. Correspondingly, insulating boards made of different materials also have different properties and different performances.

There is a G10 insulating board with relatively high mechanical strength, which has excellent dielectric properties, relatively high compressive performance, and strong heat resistance. Here you can take a look at this article on the performance of the insulation board: What are the characteristics of the performance of the insulation board? Why is it popular.

Insulation board standards and applications

The application field of insulation board is also relatively wide. The common forms of insulation board are insulation pads, insulation gaskets, insulation rings, and insulation blankets; among the many products, insulation board operations are widely used in substations, power plants, and power distribution rooms , Laboratory, field live work, and home decoration.

The standard for insulating board materials given by the country is also relatively strict. We know that this aspect of insulating materials mainly depends on how much surface dielectric we can break down. The technical copy surface: 8mm thick insulating board 10000V under voltage 10KV 1 No breakdown in minutes, 18000V in the power frequency withstand voltage test, breakdown in 20 seconds. The voltage of the power distribution room is 35KV 10-12mm thick power frequency withstand voltage test 15000V in 1 minute without breakdown, in the power frequency withstand voltage test 26000V, 20 seconds Wear. The power frequency withstand voltage test of 5mm thick and 500V below the low voltage of the power distribution room is 3500V without breakdown in 1 minute. In the power frequency withstand voltage test at 10000V, there is no breakdown in 20 seconds! These are also what we need to pay attention to in the national insulation board products of.
