DC cables are the “life veins“ of every PV system. In comparison with other PV structure parts, the DC cabling makes only 1% of the total investment costs of a new solar power plant. The cost savings from buying cheap cable harnesses are lost quickly in case of increased contact resistances or leakage current losses .
The ArCon DC cabling system offers first-class quality at a good price-performance ratio. No other cabling harness system for solar power plants has a comparable degree of impermeability as our Arcon series manufactured in Germany. The ArCon system is ideally suited for the construction of floating PV power plants.
- No loss of yield due to minimal contact resistance
- No system failures due to extreme weather resistance
- Low O&M expenditure due to high-quality standard
- 25 year of expected service life
- Proven system
- Excellently suitable for floating PV power plants
- Easy to integrate, modular system with many accessories
- Comprehensive product range for implementing a 1500 V DC system (module clips, substructures, DC cables)
Unique vulcanization process
The uniquie vulcanization process creates an irreversible chemical bond between the cable sheath and the ArCon.
Vulcanization ensures permanent tightness, even under mechanical stress and extreme climatic conditions. The ArCon encloses the joints with the same material as the sheathing of the respective photovoltaic cable.
