Underground power cables are widely used in farm irrigation systems, rural power grids and industrial distribution projects. Aluminum cables are favored for their cost advantage and lightweight performance. However, buried environments bring constant corrosion threats, which easily cause cable aging, conductor damage and unexpected power outages.
PE and HDPE outer sheaths are the mainstream choice for underground aluminum cables. High-density polyethylene resists acid, alkali and moisture penetration. For severe corrosion areas, double-layer sheath structure is recommended.
Avoid direct contact between cables and sharp stones. Use fine sand to pave the bottom of cable trenches. Do not lay cables directly on soil rich in fertilizer or industrial waste. Maintain proper burial depth to reduce temperature and humidity changes.
Heat shrinkable sealing sleeves can prevent groundwater from invading cable joints. Joint points are the weakest position and most vulnerable to corrosion failure.
Long-term buried cables cannot be visually checked. It is suggested to test insulation resistance every 1–2 years. Early warning can effectively avoid sudden circuit breakdown in irrigation seasons.
Our underground aluminum power cables adopt anti-aging HDPE sheath, strict extrusion production process, and pass complete anti-corrosion and waterproof testing. Suitable for agricultural irrigation, outdoor buried power transmission projects. As the parent factory of TYXT Trade, we provide stable, cost-effective cable solutions for global buyers.
Corrosion failure is one of the top reasons for underground cable replacement. Proper cable selection and standardized installation can greatly prolong service life and reduce later maintenance costs.
