• Confirm System Voltage: This product is designed for 0.6/1kV low-voltage systems and is not suitable for medium- or high-voltage applications.
• Select the appropriate conductor cross-sectional area and number of cores based on the load current, transmission distance, and design drawings. For long-distance transmission, the cross-sectional area should be appropriately increased to control voltage drop.
• For projects with high fire protection requirements, enclosed public spaces, or densely populated areas, it is recommended to select flame-retardant or low-smoke halogen-free (LSZH) series cables.
• For areas with severe corrosion such as strong acids, strong alkalis, or heavy salt spray in coastal areas, additional anti-corrosion measures should be added or a dedicated anti-corrosion cable model should be selected.

• Construction Temperature: Do not perform laying operations when the ambient temperature is below 0℃ to prevent brittle cracking of the sheath and insulation layer.
• Bending Control: Strictly adhere to the specified minimum bending radius during operation, avoiding sharp bends, twisting, and excessive compression to prevent damage to the internal insulation layer.
• Traction Operation: Control the traction force evenly during cable traction. Excessive tension can cause conductor deformation and armor dislodgement.
• Direct Burial Requirements: Lay a layer of fine sand around the cable and cover it with protective bricks or concrete slabs to isolate it from sharp stones and hard debris.
• Terminal Production: Use specialized aluminum conductor terminals and employ standardized crimping processes to ensure a secure connection and prevent overheating at the joint.

• Document Verification: During procurement, check factory inspection reports, product qualification certificates, and test reports to ensure products meet national standards.
• Visual Inspection: Inspect the cable surface for cracks, scratches, and incomplete markings; verify that the model, specifications, and rated voltage are consistent.
• Batch Sampling: For large-volume orders, arrange sampling inspections of insulation performance and outer sheath quality as needed.
• Storage Rules: Store cables in a dry, ventilated, and cool warehouse, away from open flames, chemical reagents, and ground moisture. Avoid long-term open-air storage and direct sunlight.
• Inventory Planning: Arrange procurement quantities according to the construction schedule to prevent long-term stockpiling from affecting cable performance.
