Photovoltaic cable
1 Product Standard:
Photovoltaic Cables (cables for photovoltaic modules) currently lack national or industry standards; the requirements addressed in this test specification are derived from the German Standards Committee. Photovoltaic System wiring K411.2.3 The working group’s preliminary draft. This draft will be published as a draft for approval as a German national standard.
Rhein, Germany TUV( Shanghai ) This technical specification will be used to Photovoltaic The performance of the cable is tested and evaluated.
In the Rhine, Germany TUV The document number for this technical specification within the company is 2PfG 1169/08.2007 。
2 Scope of application:
Photovoltaic cable is a type of cable used in solar photovoltaic module systems ( Photovoltaic System (photovoltaic system) Specialized cables for photovoltaic systems (also known as solar power systems) feature excellent resistance to weathering, high temperatures, and abrasion. They boast an exceptionally long service life, with premium oxygen‑free tinned copper conductors ensuring superior electrical conductivity. The high‑performance insulation and jacket materials, cross‑linked by high‑energy electron irradiation, deliver rock‑solid insulation and mechanical properties. These cables are easy to process and install, offering a broad processing window and straightforward handling. As a green, halogen‑free product, they emit minimal toxic fumes and smoke in the event of a fire. It is widely used for electrical wiring in indoor and outdoor solar‑energy installations and for connecting photovoltaic systems, and is suitable for desert environments with large diurnal temperature swings, coastal areas subject to salt‑fog and high humidity, as well as high‑altitude regions with intense solar radiation.

Cross-section of a conductor 1.5，2.5，4，6，10，16，25，35mm2
Conductor: IEC60228 5 Class-stranded tinned copper wire
Insulation: Cross-linked, low-smoke, halogen-free, flame-retardant polyolefin. Thickness > 0.5mm and complies with the customer‑specified limits.
Jacket: Cross-linked low-smoke halogen-free flame-retardant polyolefin , black . Thickness > 0.5mm , adopt 150 ℃ Halogen-free flame-retardant photovoltaic cable irradiation‑crosslinked insulation compound (because the maximum temperature is 120 ℃, which must be higher than that), is primarily formulated from halogen-free, non-toxic modified polyolefin resins, with the addition of halogen-free, non-toxic flame retardants, heat stabilizers, smoke suppressants, mold inhibitors, and other additives. It contains no halogens (a requirement particularly emphasized in Europe), heavy metals, or phosphorus. Furthermore, it complies with… ROHS , the insulation resistance changes little after immersion in water.

4 Product Features:
4.1 Rated voltage:
Air conditioning ： U0/U=0.6/1kV
DC ： 1.8 kV( Core-to-core, non-grounded system , Circuit under no load )
If the cable is used in a DC system, the rated voltage between its conductors shall not exceed that of the cable. Air conditioning Rated value U of 1.5 times. In a single-phase grounded DC system, this value should be multiplied by 0.5 The coefficient of.
4.2 Ambient temperature: -40 °C to +90 °C
4.3 Maximum operating temperature of the conductor: 120 °C (Allow 5s Internal short-circuit temperature 200 °C). The maximum ambient temperature for cable operation is up to 90 °C. According to EN60216-1 The standard is assessed, and the temperature index of its insulation and sheath is 120 °C.
4.4 Design life: 25 year
4.5 It does not melt or flow at high temperatures.
4.6 Highly flame-retardant, passes the vertical burning test.
4.7 Heat-resistant, cold-resistant, wear-resistant, UV-resistant, ozone-resistant, and hydrolysis-resistant.
4.8 It possesses excellent mechanical strength, is waterproof and oil-resistant, and resistant to chemicals.
