AI Technical Summary
Traditional photovoltaic cables rely on a single flame-retardant layer for fire resistance, which is prone to failure at high temperatures. Furthermore, their moisture-proof and fire-resistant structures are independent of each other, failing to meet the multiple safety requirements in complex environments.
The core fire-resistant structure is designed with a composite structure of ceramicized silicone rubber fire-resistant layer and mica tape fire-resistant layer, combined with an aluminum foil moisture-proof layer and water-resistant yarn for moisture-proof structure, a glass fiber braided layer and silicone rubber buffer layer for mechanical reinforcement, and an outer protective cross-linked polyethylene inner sheath, metal armor layer and halogen-free low-smoke flame-retardant outer sheath, forming an integrated fire-resistant, moisture-proof and mechanical strength-enhancing structure.
It effectively blocks flame and heat conduction at high temperatures, prevents moisture penetration, improves the cable's tensile and impact resistance, and ensures long-term stable operation in complex environments, thus guaranteeing cable safety.
