Today I would like to introduce to you the insulation material G11 high elastic epoxy resin sheets used for high speed railway electrical equipment. What are the advantages of using it in high speed rail? What material is G11 high elastic epoxy resin sheets? And so on. Let me give you a detailed description.

First of all, what material is the G11 high elastic epoxy resin sheets processed from?

It is now one of epoxy plates with the best performance, the main processing materials are epoxy resin and electrical glass cloth by high temperature and hot pressing. In fact, it is a synthetic polymer compound.

What are the advantages of G11 high elastic epoxy resin sheets for high-speed rail equipment?

(1) Insulation. The most important thing for electrical equipment is insulation. Only insulation can better guarantee the safe operation of electrical products. Today, the G11 high elastic epoxy resin sheet has a breakdown voltage of up to 40KV. It is still not possible to achieve its breakdown voltage.

(2) Strong thermal stress. Its thermal stress of G11 high elastic epoxy resin sheets is as high as 288 degrees. As the name implies, it is the internal stress generated by mutual constraint when the object is subjected to temperature change, and the expansion deformation or contraction deformation is inconsistent. Its thermal stress is high, greatly reducing the impact of temperature on the performance of the G11 high elastic epoxy resin sheets.

(3) High temperature resistance. Its high temperature resistance value is about 160 degrees, which is the largest high temperature resistance value in the epoxy plate. Its high temperature resistance postpones the adverse effects of high temperature on material delamination, crack, color dimming and performance weakening.

(4) Good elasticity. This is convenient for people to process into different kinds of G11 sheets, and its good elasticity can slow down the impact of external forces on the plate.

(5) Flame retardant. G11 high elastic epoxy resin sheet is a flame retardant material and is rated to UL 94V-0. In case of fire due to aging of materials or other reasons, materials can well prevent the spread of fire, so as to win more time for rescue and minimize the loss.

Note: High-speed rail is now an important means of transportation for land people to travel, and it is also the third important diplomatic event in China after pandas and ping pong, which greatly reduces the distance between us and the world. Naturally, we should carefully choose every component of such high-end equipment. In terms of insulation materials, G11 high elastic epoxy resin sheet has won the favor of people because of its high performance.
