In the field of new energy power, the stability and reliability of the cable system directly affect the overall operating efficiency and service life of the project. With the rapid development of the photovoltaic and wind power industries, cable materials must adapt to more stringent environmental challenges. XLPE (Cross-linked Polyethylene) has become one of the key materials for photovoltaic cables and wind power cables due to its excellent comprehensive performance.
XLPE (Cross-linked Polyethylene) is a polymer material that cross-links polyethylene molecular chains by physical or chemical means. The cross-linked polyethylene material has better thermal stability, mechanical strength and insulation properties, and is widely used in the insulation layer and sheath layer of the cable.
Angreen's Flame Retardant XLPE
In photovoltaic systems, Material XLPE is mainly used in the following three types of cable structures:
| Cable Type | XLPE Application Location | Functional Description |
| DC Output Cable (Such As PV1-F, EN50618) | Insulation, Sheath | Transmitting direct current of photovoltaic modules, requiring long-term high temperature resistance, light resistance, and anti-aging |
| Cable From Combiner Box To Inverter | Insulation, Sheath | Frequently exposed outdoors, requiring excellent mechanical properties and environmental tolerance |
| PV Energy Storage Battery Connection Cable | Insulation, Sheath | Insulation, anti-aging, high dielectric |
Wide long-term working temperature range: XLPE material has a conventional temperature resistance of up to 90°C and a short-term temperature resistance of up to 250°C, which can adapt to high temperature environments caused by direct sunlight and component heating.
Excellent UV resistance: Suitable for outdoor exposure scenes, with anti-UV formula to extend the life of the sheath.
Good flame retardant performance: Meets the flame retardant grade requirements of common photovoltaic cable standards such as EN 50618 and IEC 62930.
High mechanical strength and resistance to environmental stress cracking: Maintain structural stability in wind, sand, high temperature and temperature difference environments common in photovoltaic projects.
| Wind Power Part | Use Cable | XLPE Application | Application Characteristic |
| Inside The Wind Turbine Tower | Control Cable/Power Cable | Jacket+Insulation | Vertical wiring, high temperature, high mechanical load |
| Rotary Connection Section (Slip Ring Part) | Flexible Cable | Jacket | High frequency torsion, fatigue resistance requirements |
| Offshore Wind Power/Underground Transmission Section | High Voltage Cross-linked Cable | Insulation | Long distance, voltage resistance, salt spray resistance |
Angreen's Tear Resistance XLPE
Stable insulation performance: XLPE has high dielectric strength and good volume resistivity, suitable for high voltage transmission in wind power systems.
Excellent cold resistance: Suitable for low temperature environment, maintaining good softness and impact resistance.
Resistant to moisture and heat, and salt spray: Corresponding additives can be added to the formula, suitable for offshore wind power environment (material properties should be customized according to project requirements).
Strong processing adaptability: Adapt to the production needs of wind power cables with different structural forms, including single-core, multi-core, shielded cables, etc.
XLPE, as an insulation and sheath material widely used in photovoltaic and wind power cables, has excellent electrical properties, environmental tolerance and processing stability. According to different project scenarios, XLPE materials with specific properties can be selected, such as high temperature resistance, UV resistance, low smoke and halogen-free, environmental stress cracking resistance, etc., to meet the standards and application requirements of different countries.
