A 35mm2 1-core XLPE cable is a single-core electrical cable with a cross-sectional area of 35 square millimeters, insulated with cross-linked polyethylene (XLPE). It is typically used for power distribution in various applications, including building wiring, industrial plants, and underground installations where mechanical damage is not a concern. Here's a more detailed breakdown: Key Features: 35mm2: This refers to the cross-sectional area of the copper conductor, indicating the cable's current-carrying capacity. 1-core: This means the cable has a single conductor, as opposed to multi-core cables designed for multiple circuits. XLPE Insulation: Cross-linked polyethylene (XLPE) is a type of insulation known for its excellent electrical properties, heat resistance, and durability. Copper Conductor: The cable typically uses a stranded copper conductor for efficient electrical conductivity. PVC Sheath (often): A polyvinyl chloride (PVC) sheath is commonly used as an outer layer to protect the insulation and conductor from environmental factors. Applications: Power Distribution: Primarily used for transmitting electrical power in various settings. Building Wiring: Suitable for wiring within buildings, both indoors and outdoors. Industrial Plants: Used for power distribution in industrial facilities. Underground Installations: Can be buried directly or installed in ducts, often in locations where mechanical damage is unlikely. Advantages of XLPE Insulation: High Temperature Rating: XLPE can withstand higher operating temperatures compared to some other insulation materials. Excellent Electrical Properties: Provides good insulation and low dielectric losses. Resistance to Moisture and Chemicals: XLPE is relatively resistant to moisture and various chemicals, making it suitable for diverse environments. Long Service Life: XLPE insulation is known for its long-term reliability and durability. Standards: XLPE cables are manufactured to comply with various international standards such as IEC 60502-1
