BVV wire and cable life cycle, such as most copper-core PVC wire design life cycle between 20-30 years, telephone line design life cycle of 8 years, network cable design life cycle within 10 years.

When the photovoltaic cable in the process of operation through a certain load current, will generate a certain amount of heat, with the increase in cable load current, the surface temperature of the cable will gradually higher, if not dealt with in a timely manner, the consequences can be imagined.

Photovoltaic cable aging is very common, the speed of cable aging and the quality of the wire and the use of the situation, in the case of constant use of the wire, the better the quality of the wire, the aging rate will be relatively slow so as to extend the service life.

According to my recent understanding, a part of the residents as well as construction engineering personnel are not very well understood the difference between low-voltage and high-voltage cables of photovoltaic cables, then today I will solve this confusion for you.

Compared with the AC cable, the DC cable has the following characteristics
