China Suppliers CNKA offers the latest photovoltaic solar cables, specifically designed for connecting solar photovoltaic system panels. A photovoltaic system, or solar panel, is an electrical power generation setup that absorbs sunlight and converts it into electricity. While solar panels generate electricity, photovoltaic solar cables are crucial for transmitting and distributing this electricity to collection points or other devices.
Photovoltaic solar cables are engineered to meet the unique demands of photovoltaic environments. Electricity in power transmission is categorized into two types: alternating current (AC) and direct current (DC). Unlike AC, DC has lower energy loss during transmission. Direct current flows continuously, leading to minimal losses and higher efficiency. This results in faster and more energy-efficient power transmission, making DC the preferred choice for solar power systems.

1 Solar photovoltaic systems operate under high temperatures and various environmental conditions. With the development of these systems, photovoltaic DC cables have become the standard for transmission in various photovoltaic power plants. These cables must be resistant to sunlight and high temperatures to meet environmental demands.
2 Photovoltaic DC cables are specifically designed for use in photovoltaic equipment. Some types are used for underground service entrance applications and are typically made from irradiated cross-linked insulation materials, offering resistance to sunlight and suitability for direct burial.
3 Photovoltaic DC cables differ from other cables in insulation thickness, rated voltage, and operating temperature. These cables feature a thicker insulation layer to withstand harsh environments. While other cables may have a rated voltage of up to 600V, photovoltaic DC cables can reach a rated voltage of 1500V.
4 Photovoltaic DC cables can endure higher temperatures compared to other cable types, which generally have a maximum operating temperature of 90°C.
5 Photovoltaic DC cables are unique as they are among the few single conductor types with a rated voltage exceeding 600V, suitable for direct burial without the need for additional shielding.
