G11 epoxy sheet is a good insulation material for high voltage switchgear

High-voltage switch manufacturing industry is an important part of power transmission and transformation equipment manufacturing industry, which occupies a very important position in the whole power industry. The material that it uses allows no carelessness, and it must pass the strict test of the country concerned branch. Take insulation materials for example, the garolite G11 insulation material has won people's favor. Why? A lot of friends who are not very clear about this industry will certainly have some questions. You want to know? And then we go down.

Insulation performance

From the name of high voltage switchgear, it is not difficult to see that it is a high voltage equipment, insulation is inevitable naturally. It also requires high insulation, and the garolite G11 epoxy sheet is resistant to high voltage up to 40KV, and it has good water absorption. Water absorption rate is almost 0; After 24 hours of immersion, the water absorption rate is only 0.09 %.

High temperature resistant

High pressure naturally produces a certain temperature, and the equipment typically operates 24 hours a day. The generation of heat is inevitable. The G11 insulation material has a high temperature resistance of up to 160 degrees. G11 material is suitable for the needs of current high voltage switchgear.

Anti-static feature

With such a high voltage, static electricity is inevitable. Static electricity has a great effect on the switchgear. It is possible to cause the failure of the switchgear, which may endanger people's lives and property.

Flame retardant

The flame retardant properties of garolite G11 meet the 94V-0 standard. In this way, even in case of fire, it will give us more time to rescue and reduce the loss.

High mechanical strength

Mechanical strength refers to the maximum load its unit area can bear when subjected to external force action. This can increase the life of the G11 material.

Through the above description, I think you have your own answer to why G11 insulation sheet is a good material for high voltage switchgear.
