What is a solar DC cable
solar cables, also known as solar special cables, are mainly used in photovoltaic power stations. They have the advantages of high temperature resistance, cold resistance, oil resistance, acid and alkali resistance, UV protection, flame retardant and environmental protection, and long service life. They are mainly used in harsh climate conditions; Commonly used models are PV1-F, H1Z2Z2-K. Ordinary cables, also known as PVC or PE insulated wires, are mainly used for electrical installation and home decoration wiring. They have certain weather resistance, mechanical strength and good electrical insulation. High performance (-45°C~+125°C), it is not suitable for outdoor and harsh environmental conditions, and cannot replace photovoltaic wires.
DC solar cables are used for connecting cables of photovoltaic power generation systems, such as parallel cables between strings and between strings and DC distribution boxes (combiner boxes), series cables between PV modules and modules on the DC side, and strings. The cross-linked cable between the DC distribution boxes (combiner boxes) between the strings and the DC distribution box to the inverter, and also the AC application cable used for the connection between the inverter and the transmission network. .
