CNKA's discounted price list for 4mm PV solar cables caters to specialized cables used to connect solar panels and inverters, commonly known as photovoltaic cables. These cables are designed for solar systems operating at voltages ranging from 600 to 1000 volts AC and 1500 volts DC. They are particularly suited for harsh environmental conditions including high temperatures and exposure to ultraviolet radiation.
Solar cables differ from conventional cables due to their unique characteristics, including high and low temperature resistance, oil resistance, resistance to acids, alkalis, and salts, UV resistance, flame retardancy, and environmental friendliness. These features ensure reliable performance and durability in solar energy applications.

Q: What is a PV cable?
A: Photovoltaic cable, commonly known as PV wire, is a single conductor wire used to connect solar panels or PV systems in photovoltaic electric energy systems. PV systems harness sunlight to generate electricity through energy conversion.
Q: What are the different types of PV cables?
A: Typically, there are three main types of cables used in photovoltaic (PV) systems: DC solar cables, Solar DC main cables, and Solar AC connection cables.
Q: What are the uses of DC circuit breakers?
A: DC circuit breakers are used to protect specific loads powered by DC, or to safeguard primary circuits such as inverters, solar PV arrays, or battery banks.
