Dc pv solar cables are mainly composed of three parts: core (conductor), insulation layer and sheath (). Different parts have different materials and play different roles.
The core is the path for conducting current. Commonly used dc pv solar cable core materials are copper or aluminum. They have higher electrical conductivity and smaller line losses.
The insulating layer can isolate the effect of the high electric field on the conductor on the outside world. Common insulating materials include: oil-impregnated paper, polyethylene, polyvinyl, cross-linked polyvinyl, and ethylene-propylene rubber.
The sheath is also called the sheath, which protects the dc pv solar cable core and insulation layer, and protects the core and insulation layer from external damage, moisture, penetration, and corrosion. It is generally composed of two parts: a metal protective layer and an insulating protective layer.
The characteristics of photovoltaic cables are selected by their special insulating materials and sheath materials for dc pv solar cables, which we call cross-linked PE. After being irradiated by an irradiation accelerator, the molecular structure of the dc pv solar cable material will be changed, and then various aspects of it will be supplied. functi
