Common models of photovoltaic DC cables include PV1-F-DC, H1Z2Z2-K, PV-YJYJ, and GFDC-YJVB. These models are specifically designed for solar energy systems and are suitable for DC power transmission in harsh outdoor environments.
Main models and features:
PV1-F-DC: Specifically designed for series connection of photovoltaic modules, parallel connection of strings, and connection from DC distribution boxes to inverters. It features UV resistance, high and low temperature resistance (-40℃~+90℃), low smoke, halogen-free flame retardancy, and a rated voltage up to DC 1.8kV, meeting German TÜV certification standards.
H1Z2Z2-K: A mainstream European photovoltaic DC cable model, suitable for interconnecting solar panel arrays. It has excellent anti-aging, high temperature resistance, and UV resistance, but is not recommended for direct burial.
PV-YJYJ and GFDC-YJVB use cross-linked polyethylene (XLPE) insulation, offering high mechanical strength and excellent weather resistance, making them suitable for long-term outdoor use. They are widely used for series connection between modules and DC bus connections.
DC bus cables (such as the YJVHD series) are primarily used for power transmission between the combiner box and the inverter. Some models feature armored protection, enhancing tensile and abrasion resistance, making them suitable for cold or high-temperature regions in northern China.
