The International Status Of Solar Photovoltaic Cables

Characteristics of outdoor photovoltaic cables.


Currently commonly used TUV photovoltaic cables are environmentally friendly. It has good corrosion resistance and high temperature resistance. From the perspective of the impact of the cable on the environment, the cable belongs to the green cable. The earliest PV cables were PVC insulation and rubber jackets, which have been eliminated from the European market.

In recent years, the technology of the photovoltaic industry has developed faster and faster, the power of a single module has become larger and larger, and the current of the string has become larger and larger, and the current of high-power modules has reached more than 17A.

Centralized photovoltaic power stations generally use centralized inverters, at least 100KW inverters. At this time, the string will pass through the DC combiner box and then connect to the inverter. At this time, the wire diameter is determined according to the current.

The characteristics of photovoltaic cables are determined by the special insulating materials and sheathing materials for cables, which we call cross-linked PE. After being irradiated by an irradiation accelerator, the molecular structure of the cable material will change, thereby providing its performance in all aspects. 

Resistance to mechanical loads In fact, during installation and maintenance, cables can be routed on sharp edges of roof structures, while cables are subject to pressure, bending, tension, cross tensile loads and strong shocks.

If the cable jacket is not strong enough, the cable insulation will be severely damaged, affecting the service life of the entire cable, or causing problems such as short circuits, fire and personal injury hazards.
