PV Cable AC 0.6/1kV DC 1500V Photovoltaic DC cable Single Core 2 Cores Solar Cable

Photovoltaic cable is an electron beam cross-linked cable with a rated temperature of 120°C, which can withstand harsh weather and mechanical shocks in its equipment. According to international standards, the service life of solar cables in outdoor environments is 8 times that of rubber cables and 32 times that of PVC cables. These cables and components not only have good weather resistance, UV and ozone resistance, but also can withstand a wider range of temperature changes (for example: from –40°C to 90)

Description

Photovoltaic cable is a special type of cable used in solar power generation systems. It is mainly suitable for DC voltage terminals, lead connections of power generation equipment and bus connections between components, and high voltage DC1.8KV photovoltaic power generation equipment systems. It has the characteristics of weather resistance, cold resistance, high temperature resistance, friction resistance, UV resistance and ozone resistance, and a service life of at least 25 years.
The high-quality oxygen-free tinned copper conductor guarantees its superior conductive effect. The high-performance insulating material and sheath material after radiation cross-linking by a high-energy electron accelerator have reliable insulating and mechanical properties. This product is a green product with the characteristics of halogen-free, low-smoke, low-halogen and low-smoke. Once a fire accident occurs, the flame spreads slowly, the smoke concentration is low, the visibility is high, the release of harmful gases is small, it is convenient for personnel to evacuate, and there are more Time to deal with the fire.

Electrical properties

1. DC resistance
The DC resistance of the conductive core of the finished cable at 20°C is not more than 5.09Ω/km.

2. Immersion voltage test
The finished cable (20m) will not breakdown after being immersed in (20±5)℃ water for 1h after 5min voltage test (AC 6.5kV or DC 15kV).

3. Long-term DC voltage resistance
The sample is 5m long and put into distilled water containing 3% sodium chloride (NaCl) at (85±2)℃ for (240±2)h, with both ends exposed to the water surface 30cm. A DC 0.9kV voltage is applied between the core and the water (the conductive core is connected to the positive electrode, and the water is connected to the negative electrode). After taking out the sample, perform a water immersion voltage test. The test voltage is AC 1kV, and no breakdown is required.

4. Insulation resistance
The insulation resistance of the finished cable at 20℃ is not less than 1014Ω·cm,
The insulation resistance of the finished cable at 90℃ is not less than 1011Ω·cm.

5. Sheath surface resistance
The surface resistance of the finished cable sheath should not be less than 109Ω.
