On today's energy stage, the photovoltaic industry is like a bright new star, shining with infinite light. In this new energy revolution, there is a behind-the-scenes hero who is little known but plays a vital role. It is Photovoltaic Cable Compound.
1. What is Photovoltaic Cable Compound?
Photovoltaic cable compound, as the name suggests, is an insulation and sheath material specifically used for cables in photovoltaic systems. It is like the "outer coat" of photovoltaic cables, providing protection and insulation for the cables. In photovoltaic power stations, photovoltaic cables play an indispensable role from the conversion of light energy into electrical energy by solar panels to the transmission of this electrical energy to the power grid or energy storage equipment, and photovoltaic cable compounds are the key materials to ensure the smooth progress of this process.

2. Unique properties of photovoltaic cable compounds
(I) High temperature resistance
Photovoltaic power stations are usually located outdoors and face various complex environmental conditions. In the hot summer, the surface temperature of solar panels may reach 80°C or even higher, and photovoltaic cable compounds must be able to remain stable in this high temperature environment. It will not soften, deform or age due to high temperature, ensuring that the insulation performance of the cable is not affected. This high temperature resistance is like putting a "fireproof coat" on the cable, making it indestructible under the high temperature "test".
(ii) UV resistance
Ultraviolet rays are a major "killer" in the outdoor environment. They will cause serious damage to ordinary cable materials, causing material aging and cracking, thereby causing safety hazards such as leakage. Photovoltaic cable materials are specially formulated and have excellent UV resistance. It can effectively resist the erosion of ultraviolet rays, just like holding up a "sunshade" for the cable, so that it can still maintain good performance in an environment exposed to the sun for a long time, extending the service life of the cable.
(iii) Chemical corrosion resistance
The construction environment of photovoltaic power stations is diverse and may be exposed to various chemicals, such as acid rain, salt spray, etc. Photovoltaic cable materials have good chemical corrosion resistance, which can resist the erosion of these chemicals and protect the conductors inside the cable from damage. Whether it is an acidic or alkaline environment, it can act like a "guardian" to provide all-round protection for the cable and ensure the stable operation of the photovoltaic system.
(IV) Good mechanical properties
During installation and use, photovoltaic cables may be subjected to various mechanical stresses, such as stretching, bending, and extrusion. Photovoltaic cable materials have good mechanical properties and can withstand these external forces without damage. It has high tensile strength and flexibility, making the cable more convenient and safer during laying and use. Even in complex terrain and harsh installation conditions, the cable can remain intact and will not cause electrical failures due to mechanical damage.
