Epoxy pipe is a kind of insulating material. Its insulating performance is closely related to temperature. The higher the temperature, the worse the insulating performance. In order to ensure the insulation strength, each insulating material has an appropriate high allowable operating temperature. Below this temperature, it can be used safely for a long time, and it will age quickly if it exceeds this temperature.

According to the degree of heat resistance, the insulating materials are divided into Y, A, E, B, F, H, C and other levels. For example, the high allowable working temperature of Class A insulating materials is 105°C, and most of the insulating materials used in distribution transformers and motors generally belong to Class A.

How to avoid the rapid aging of epoxy pipe?

1. Avoid strong sunlight

Light aging is mainly through sunlight radiation to achieve the purpose of damaging the epoxy pipe, which often results in loss of gloss. Fading, white flowers, peeling and other undesirable phenomena. Therefore, under normal circumstances, do not allow the board to be exposed to direct sunlight. Even if you want to prevent moisture, you must dry it in the shade and air.

2.Pay attention to the use temperature

The service temperature of the epoxy pipe is about 155 degrees. Try not to exceed the larger service temperature of the sheet. If it exceeds the sheet, it will cause bending and poor insulation performance. And every 8°C increase in ambient temperature reduces the life span by half.

3.Reduce mechanical vibration

With the operation of electrical equipment nowadays, the vibration and noise generated by mechanical equipment have serious hazards to the aging of insulating materials.

4.Avoid high voltage

The withstand voltage of epoxy tubes is as high as tens of kilovolts, but those are critical values. During specific use, the voltage should not be too high. Partial discharge may occur in high-voltage electrical equipment due to uneven dielectric or uneven electric field distribution, Discharge will emit various rays and sound waves, which will also damage the material. These will cause the aging of the insulation material.
