When buyers use the wire, the first thing we see is the appearance of the wire and certification, the wire must be printed with 3C certification mark. Wire and cable products are national mandatory safety certification products.

Nylon cable is a product used in daily life, its good or bad is directly related to our electricity safety, after all, the cable product quality is not good, in the actual process of electricity, it will be damaged because of the current through, the temperature is too high.

Photovoltaic cable laying construction is an extremely important project, in order to ensure its normal operation, from time to time, if there is a failure, it must be laid to exclude the possibility of problems, and the premise of excluding the problem lies in the construction of the cable, the nex

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.

There are many types and specifications of photovoltaic cables on the market today, coupled with the proliferation of various poor quality wires, so many consumers choose cables but do not know from how to pick, I will now go into more depth about the simple but important aspects of insulation. Why

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.

We often see the engineer laying the cable surface printed with the letters ZC and ZR at the time of work in the engineering site, see this after and engineer to understand that these are flame retardant cable, but what is the difference between cable ZR and ZC?
