Solar cable definition
2024-06-11
Solar Cable is a special cable in the solar photovoltaic power generation system
Solar cable classification is divided into DC cable and AC cable by use
- DC Solar cable
assembly and the series cable between the panels.we have High-Quality 62930 IEC 131,Single Core Solar Pv Cable,Famous 10mm Solar Cell Cable.
Parallel cables between the series and between the series and the DC distribution box (bus box).
Cable between DC distribution box and inverter. We have China Twin Core DC Solar Cable,China 8mm Solar Panel Connector, China 10mm2 Single Core DC Cable.
- More outdoor laying, need moisture, sun, cold, heat, UV resistance, some special environment also need to prevent acid and alkali and other chemicals.IF you Wholesale Waterproof Electric Power Solar Cable,please contact us,we Wholesale Outdoor Sola Cable.
Structure and material
Structure features Double-layer insulation protection, oxygen-free copper tinning to ensure more than 25 years of service life.Tinned Copper Double Core Solar Cable
material selection
Conductor material: oxygen-free tinned copper or aluminum alloy
insulation material: irradiated low smoke halogen-free flame retardant polyolefin
jacket material: irradiated low smoke halogen-free flame retardant polyolefin
Characteristics of solar cable
Double insulation protection, oxygen free copper tin plating to ensure more than 25 years ofservice life
High temperature resistance, cold resistance, oil resistance, acid,alkali and salt resistance, UV protection, flame retardant,environmental protection, can ensure the vast majority of harsh outdoor environment for long-term use.
performance feature
1. Strong weather resistance
The Solar cable has excellent weather resistance and aging resistance, and can resist the influence of bad weather conditions to ensure its 25-year service life
2. High conductivity
The cable conductor adopts oxygen-free copper with copper content of more than 99.6%, which has excellent conductive performance and reduces energy loss.
3. Environmental protection safety
Solar cable in line with (ROHS2.0, etc.) environmental standards, low smoke halogen-free, non-toxic and harmless, safe and reliable use.
4. High temperature resistance
The cable can be used in the harsh conditions of -40℃-90℃ for a long time, and can be used in the environment of up to 120℃ for 20000h.
Certification
H1Z2Z2-K EN 50618:2014 TUV certification
62930 IEC 131 IEC62930-2017 TUV certification
PV 1500V-AL PPP 11029:2019 TUV certification
H07V-R EN50525-2-31 CE certification
Construction safety and quality control
The DC cable model should meet the requirements of the design drawings, the appearance is intact, there is no damage mark, the handwriting is clear, and the cable should be laid separately.
Cables on the DC side of the photovoltaic system should be dedicated to the photovoltaic system.
The DC tube of the solar DC cable to the inverter is fixed (the wire tube must be selected as a special fireproof type, and the fixed pipe card should be stainless steel horse card and be horizontal and vertical, and the pipe card spacing is not more than 1.8m);
Use a PE hose at the DC end of the inverter to connect the DC connector of the inverter. Ensure that the PE hose and the hard-wired pipe are waterproof
All wire pipes should be laid smoothly, bending curvature is natural, there should be no strong twisting and hard bending phenomenon, the surface of the wire pipe should not be damaged, there should be creases;
When the DC pipe is on the roof, a bend should be made to prevent the pipe from entering water and causing water to flow to the inverter
