1. Model Definition:
The FS-YJV23 is a cross-linked polyethylene insulated, steel-tape armored, PVC-sheathed, water-blocking power cable suitable for water-blocking power projects with an AC rated voltage of 35kV and below.
2. Basic Parameters:
Rated voltage: 0.6/1kV to 35kV.
Usage Environment: The installation temperature must not be lower than 0°C. The allowable bending radius during cable installation is 20D for single-core cables and 15D for multi-core cables. The cable conductor's long-term operating temperature must not exceed 90°C, and the maximum short-circuit temperature must not exceed 250°C.
Applicable Locations: Suitable for waterproofing power supply projects in critical facilities and bases such as ports, hydropower stations, tunnels, chemical plants, metallurgical plants, reservoirs, water plants, and garden lighting. It performs particularly well in high rainfall areas and low-lying, humid regions.
Structural Features: Utilizes longitudinal water-blocking and radial waterproofing technologies to effectively prevent longitudinal water penetration and lateral migration, providing shielding properties to prevent electromagnetic interference inside and outside the cable.
3. Specifications:
Nominal cross-section range: 1.5mm² to 300mm².
Number of cores: Single-core and multi-core available.
The FS-YJV23 waterproof cable is a high-performance, water-blocking power cable suitable for a variety of humid and high-risk environments, offering excellent waterproof and electrical performance.
The structural composition and material properties of the FS-YJV23 waterproof cable are as follows:
1. Conductor: Copper or aluminum core, typically high-purity oxygen-free copper (Cu), offers excellent conductivity and corrosion resistance.
2. Insulation: Cross-linked polyethylene (XLPE) is used, offering excellent electrical, heat, and chemical resistance. It effectively prevents moisture from penetrating the insulation, preventing the formation of water trees, thereby protecting the cable insulation and extending its service life.
3. Jacket: Polyvinyl chloride (PVC) or polyolefin materials are used, offering excellent weather resistance and mechanical strength, providing additional protection against external mechanical damage and moisture intrusion.
4. Armor: Typically steel tape or wire armor, it provides additional mechanical protection and resistance to external forces, making it suitable for underground installation or applications requiring high tensile strength.
5. Water-blocking layer: Water-blocking tape or yarn may be added between the insulation and sheath to block water longitudinally, preventing moisture from diffusing along the cable's length.
6. Filling material: Aluminum-plastic composite tape or polyethylene filler is added between the inner and outer sheaths to further enhance waterproofing.
7. Waterproofing: The FS-YJV23 cable features radial waterproofing. Through a special treatment process, a robust waterproof barrier is formed between the insulation and sheath, ensuring reliable operation in humid environments.
8. Applications: Suitable for use in locations requiring waterproofing, such as ports, hydropower stations, tunnels, chemical plants, metallurgical plants, reservoirs, water plants, and garden lighting, particularly in areas with high rainfall and low-lying, humid terrain.
