Qingzhou's  solar cable can be used in solar projects. Qingzhou cable will help you choose the right solar cables and wires, PV wires. Our PV wires are tinned copper and double XLPO. We can produce different solar cable types such as solar cable 4mm, solar cable 6mm, and mc4 cable. We also can manufacture solar battery cables. Solar cables are interconnection cables for photovoltaic power generation. PV Cables connect solar panels to other electrical components of the photovoltaic system. Solar wires are designed to be UV-resistant and weather-resistant. Photovoltaic cables can be used over a wide temperature range and are usually placed outdoors.

Main Cable Types in a Solar Photovoltaic (PV) System

Cable Type	Function / Application	Typical Voltage	Features
PV/DC Cable (e.g. PV1-F, H1Z2Z2-K)	Connects solar panels to combiner box or inverter DC input	600/1000V or 1500V DC	UV-resistant, weatherproof, double-insulated, halogen-free
AC Cable	Connects inverter AC output to distribution board or grid	0.6/1kV AC	Standard power cable (e.g. YJV, NYY, H07RN-F)
Earthing (Grounding) Cable	Bonds metal parts and provides safe grounding	—	Green-yellow color, corrosion-resistant
Communication Cable	Used for monitoring and data transmission between inverters and control systems	300/500V or data-grade	RS485 cable or Ethernet cable (Cat5e/Cat6)
Internal Connection Cable	Used inside combiner boxes for fuses, breakers, etc.	1000–1500V DC	High-temperature and flame-retardant rated

 
Our Solar cable products comply with EN 50618 to British standards, US standard UL4703, and the TUV certified cables. As with the TUV-certified cables, the EN50618 solar cable range has undergone a rigorous manufacturing and testing audit program to deliver a quality cable with an anticipated lifespan of circa 25 years, Including:

Advantages of PV wire:
1. Dual wall insulation. Electron beam cross-linked
 
2. Excellent resistance to U.V, oil, greases, oxygen, and ozone
 
3. Excellent resistance to abrasion  
 
4. Halogen-free, flame retardant, low toxicity         
 
5. Excellent flexibility and stripping performance     
 
6. High Voltage and Current carrying capacity         
 
The difference between Solar cable and normal cable.
Solar panel cable is UV resistant and has a wider temperature range. The life service for PV wire is 25 years. The insulation is double XLPO. Solar panel wire is suitable for outdoor and often in hot areas. PVC cable is not UV resistant. The working temperature is 90 degrees to -10 degrees. PVC cable only be used indoors. The conductors for PVC cables are copper.
