H1Z2Z2-K1×4 is a DC cable with a cross-section of 4 square millimeters used in solar photovoltaic power stations, commonly known as 4 square photovoltaic cables or 1500V photovoltaic cables. It is a photovoltaic cable model of the TUV EN50618:2014 version. In the power station, it is responsible for the connection between photovoltaic panels (photovoltaic modules) and the cables between the modules and the AC/DC inverter.
This product utilizes the advanced electron beam accelerator irradiation process, and the sheath and insulation (double-layer powder separation or double-layer non-separation) are produced by low-smoke, halogen-free, flame-retardant polyolefin materials, English representation: XLPO; conductors are stranded High-purity tin-plated oxygen-free copper wire; the product has high and low temperature resistance (-45 ° C ~ +120 ° C), anti-ozone, anti-ultraviolet (UV), anti-oxidation, strong short-term overload capacity, long service life, oil resistance , wear resistance, corrosion resistance, high tensile (mechanical strength) and other characteristics.
The rated DC voltage is DC1500V, which basically satisfies all the inverters on the market; the number of cores of photovoltaic cables is generally 2 cores and 1 core, and the specification of 1 core and 4 square millimeters is the most used; the color of single core cables is generally It is divided into two colors: black and red. The general inner core insulation of double cores is divided into black and red colors, and the outermost sheath is black. In DC lines, the red line generally represents the positive pole of the current, and the black line represents the negative pole of the current. ;The cross-section of conventional cables is: 1.5mm²~35mm², and the large square section can be customized according to the actual situation; before purchasing, it must be clear whether the manufacturer has TUV certification.
Passing the certification can at least prove that this is a professional manufacturer of photovoltaic cables. Without certification, it is difficult to guarantee the quality of the cables. In addition, it may be difficult to carry out the next step due to incomplete information during the grid connection stage of the photovoltaic project.
Jiukai Cable is one of leading solar cable manufacturers around the world and all of our solar cables are under TUV/UL/PSE standards(Highest standards in Europe and America)
