Main Advantages

1. High voltage resistance, suitable for high-voltage photovoltaic systems The cable is rated for DC 1500V, exceeding the voltage withstand standard of ordinary photovoltaic cables. It perfectly fits large centralized photovoltaic power stations and high-voltage networking systems for rooftop distributed PV projects. Its high voltage capacity effectively reduces voltage drop and line loss, improves overall power transmission efficiency of photovoltaic power generation, and meets the requirements of high-power grid-connected photovoltaic projects.
2. Outstanding weather resistance for long-term outdoor exposure Made of dedicated photovoltaic cross-linked polyolefin insulation and sheath material, it features excellent UV resistance, ozone resistance and anti-ageing performance. It can withstand harsh outdoor conditions including strong sunlight, wind and rain erosion, and alternating temperature changes between day and night. It resists cracking, whitening and ageing failure under long-term open-air laying, greatly enhancing the operational stability of outdoor photovoltaic circuits.
3. Excellent flexibility for convenient and efficient installation The conductor adopts finely stranded oxygen-free copper. The cable is highly flexible with a small bending radius and superior resistance to bending fatigue. It easily adapts to narrow and complex routing spaces such as gaps between PV modules, bracket corners and curved roof surfaces. It can be manually pulled and laid easily, shortening the wiring period of photovoltaic power stations and cutting labour costs.
4. Flame retardant and eco-friendly with high safety level Constructed with low-smoke zero-halogen flame-retardant compound materials, free from halogen and heavy metals. No corrosive gas or dense toxic smoke will be released during combustion. It has good self-extinguishing performance and restrains flame spread, effectively containing fire propagation along PV cables and meeting fire safety requirements for outdoor and centrally arranged photovoltaic power stations.
5. Stable electrical performance and low power transmission loss High-purity oxygen-free copper conductor delivers superior conductivity and low resistance, resulting in low temperature rise and low transmission loss under operation. It can stably carry photovoltaic DC loads over long periods. The insulation layer has high dielectric strength and stable voltage resistance, with good moisture-proof, waterproof and leakage-resistant properties to guarantee 24-hour continuous stable operation of photovoltaic systems.
