Key Product Performance Characteristics
1. Excellent Electrical Insulation: High dielectric strength and high volume resistivity effectively isolate stray currents from the soil, preventing leakage and short circuits in high-voltage cables. Insulation performance remains stable and undiminished over the long term.
2. Flame Retardant and Fireproof: Achieves a flame-retardant B1 rating. Self-extinguishing upon contact with an open flame, producing no toxic fumes, preventing fire spread and damage to high-voltage cables, and ensuring power safety.
3. Resistance to External Pressure and Impact: Thickened walls provide strong resistance to circumferential pressure. Undamaged by construction impacts or pressure from hard soil objects, it withstands long-term static and dynamic loads after burial without deformation.
4. Corrosion and Temperature Resistance: Resistant to soil acids, alkalis, salts, and underground damp media corrosion, requiring no additional corrosion protection. Operating temperature range: -10℃ to 70℃, with stable dimensions under temperature variations.
5. Sealing and Waterproofing: A dedicated sealing structure achieves zero leakage, effectively preventing groundwater and sediment from entering the pipe, avoiding water immersion and sediment abrasion and aging of the high-voltage cable.
Product Advantages
1. Strong High Voltage Adaptability: Specifically designed for 10kV~35kV medium and high voltage cables, its insulation and protection performance meets the core requirements of high-voltage power engineering.
2. Outstanding Cost-Effectiveness: Raw material and construction costs are far lower than high-voltage plastic-coated steel pipes and fiberglass pipes; no anti-corrosion maintenance costs throughout the entire life cycle.
3. Convenient Construction: Easy to cut, lightweight, requiring no large heavy equipment; simple on-site connection process, significantly improving the efficiency of high-voltage power line laying.
4. Wide Environmental Adaptability: Suitable for both underground and outdoor installation; resistant to soil corrosion and UV aging; adaptable to different climates and soil conditions in both northern and southern regions.
5. High Safety Protection: Triple protection of insulation, flame retardancy, and sealing provides all-round protection for high-voltage cables, reducing the risk of power line failures.
