The NYY cable features a multi-layer structure engineered for optimal performance:
It utilizes either solid or stranded copper conductors, chosen for their excellent electrical conductivity and mechanical strength. Solid conductors are ideal for applications requiring rigidity, while stranded conductors offer flexibility, making them suitable for installations with bending requirements.
A PVC insulation layer surrounds the conductor, providing effective electrical isolation. PVC is selected for its resistance to moisture, chemicals, and temperature variations, ensuring long-term insulation integrity.
The cable includes PVC filling to maintain structural stability, preventing internal components from shifting during installation or operation. An outer PVC sheath adds an extra layer of protection against external mechanical stress, corrosion, and environmental factors.
Maximum operating temperature: 70℃
Short-circuit temperature: 160℃
