PV Cable introduction
PV cable is a special cable for solar photovoltaic (PV systems (photovoltaic system): also known as photovoltaic systems solar systems ),which has features like weather-resistant,high temperature resistant,anti-abrasion and other features. This cable has a long service life.high-quality oxygen-free tinned copper conductor ensures superior conductivity effects.the high-energy electron accelerator radiation cross-linked,high-performance insulation and sheathing materials plays an absolutely reliable insulation and mechanical properties . In the processing and use of a wide range of technology and easy operation, the product is green halogen-free products in the event of fire , this product is toxic and harmful gases concurrent smoke less .
PV Cable application
2PfG 1169/08.2007 applicable maximum allowable 1.8kV (line core for core, non-grounded systems) DC voltage side of the photovoltaic system used CD single flexible cable (wire).
The product is suitable for the use of Class Ⅱ security level.
Cable runs ambient temperature up to 90 ℃.
A plurality of cables can be used in parallel
PV Cable service condition
1, Rated voltage:
AC: U0 / U = 0.6/1kV
DC: 1.8kV (line core for core, non-grounded systems, no load circuit)
If the cable is used in the DC system, the rated voltage between the conductors of the cable should not exceed 1.5 times the AC rating of U.
In the single-phase DC systems, this value should be multiplied by the factor 0.5. Operating temperature -40 ℃ ~ 90 ℃ (with> 25 years)
2, ambient temperature: -40 ℃ to +90 ℃
Maximum conductor operating temperature: 120 ℃
Cable runs ambient temperature up to 90 ℃. According to EN60216-1 standard for assessment, the insulation and jacket temperature index is 120 ℃.
The life expectancy is 25 years
The short-circuit temperature is 5 seconds 200 ℃
3, the short-circuit temperature +280 ℃
4, does not melt under high temperature, no flow
5, high flame, through the vertical flame test
6, heat, cold, abrasion, UV, ozone, hydrolysis
7, has good mechanical strength, water,oil and chemical resistance
PV Cable standards
For PV-Cables (PV modules cable),There is no national or industry standards, technical specifications of the test requirements involved from the German Committee for Standardization PV-systems with wire K411.2.3 draft of the working group. This draft will serve as the German national standard draft for approval to publish.
German Rhine TUV (Shanghai) will use this technical specification the PV-cable performance testing and evaluation.
TUV Rheinland company in this technical specification document number 2PfG 1169/08.2007.
PV Cable structureConductor : EN60228 (IEC60228, GB/T3956) in Class 5 conductors , and must be tinned .
Insulation: LSZH irradiation crosslinked polyolefin
Sheath material: LSZH irradiation cross-linked polyolefin
