Everyone knows that epoxy boards are a good material for the insulation of electrical equipment today, and today it is also a mainstream insulating sheet. So is it safe for electrical equipment? Will it become a conductor because the voltage is too high? I will give you a detailed explanation of these doubts.
(1) Its breakdown voltage is high. Vertical layer electrical strength of epoxy board (in transformer oil of 90±2 °C, thickness 1mm): ≥14.2MV/m; parallel layer breakdown voltage (in 90±2°C transformer oil): ≥40KV. Although the voltage is rising today, there is still a gap in the value of the breakdown voltage. Therefore, there is no need to worry that it will become a conductor, and that it is a malfunction of electrical equipment and damage to people’s lives and property.
(2) Good flame retardant performance. Its flame retardant performance meets UL 94V-0 standard. In case of fire due to long-term operation or material aging, the flame retardant performance of epoxy board can save people more time to rescue and minimize losses.
(3) High temperature resistance level. Especially in the hot summer months, the temperature is very high, and the electrical equipment is not intermittent, the temperature will be high. The high temperature resistance of the epoxy board is very large, so there is no need to worry about the performance of the high temperature sheet. This is dangerous.
It is not difficult to see from the above that the epoxy board is a good material for the safe operation of electrical equipment, which provides a guarantee for the safe operation of the equipment. If you have other questions? You can call us.
