GPO-3 laminate is also known asGPO-3 laminate sheet. It is a hard plate-like insulating material made of alkali free glass fiber felt soaked in unsaturated polyester resin paste and added with corresponding additives by hot pressing. GPO-3 laminate, also known as UPGM-203, refers to unsaturated polyester glass fiber felt material, which is used for mechanical and electrical purposes. It has good electrical properties under high humidity and good mechanical properties under medium temperature. It has good flame retardancy, arc resistance and leakage trace resistance.
GPO-3 insulating material pays great attention to temperature control during use. If it is not well controlled, it will cause damage to the whole material. This is a very unwise practice, which is likely to cause incalculable losses.
Therefore, we must ensure the seriousness of this problem. There must be no ambiguity. We must make preparations in this regard. In fact, this is very simple. As long as there is an air conditioner, that is to say, the working environment of this material can be adjusted to the appropriate temperature, which is the best. The temperature resistance of GPO-3 insulation sheet is grade F, which is between 155 ℃ and 180 ℃. However, it is recommended that the long-term working temperature should be controlled at about 155 ℃ to ensure the stability of the material.
Therefore, great attention should be paid to the working environment of GPO-3 insulating material to ensure that this series of problems will not occur again. This is the correct approach.
