Our 3-Layer 35kV ACSR Tree Wire Spacer Cable is a cutting-edge solution engineered for high-voltage primary and secondary overhead distribution, especially where space is limited or environmental protection is paramount. This specialized cable provides a robust and insulated alternative to bare conductors, significantly enhancing safety and reliability in challenging environments.
Key Features:
- Advanced 3-Layer Construction: This cable boasts a sophisticated insulation system for superior performance and protection:
- Conductor: High-strength ACSR (Aluminum Conductor Steel Reinforced) for excellent conductivity and mechanical integrity.
- Primary Insulation: Durable Cross-linked polyethylene (XLPE) provides robust electrical insulation.
- Outer Sheath: A tough outer layer of High-density track-resistant Polyethylene (HDPE), specifically designed to withstand abrasion and prevent tracking in the presence of moisture and contaminants.
- Optimal for Confined Spaces: Ideal for installations in congested areas like alleyways, narrow corridors, or areas with dense tree growth. Its compact design minimizes the required right-of-way and hardware.
- Enhanced Safety: While installed similarly to bare conductors, the advanced covering is highly effective in preventing direct shorts and instantaneous flashovers caused by contact with trees, wildlife, or other objects, significantly improving public and system safety.
- High Voltage Rating: Rated for 35 kV phase-to-phase, suitable for demanding high-voltage distribution networks.
- Superior Temperature Performance:
- Normal Operation: 90°C
- Emergency Overload Conditions: 130°C
- Short Circuit Conditions: 250°C
- Robust Standards Compliance: Manufactured to meet stringent industry standards including ICEA S-121-733, ASTM B231, ASTM B399, and ASTM B232, ensuring high quality and reliable performance.
Applications:
The 3-Layer 35kV ACSR Tree Wire Spacer Cable is an excellent choice for:
- Primary and secondary overhead distribution in urban and suburban areas.
- Lines running through or near trees, significantly reducing tree-trimming requirements and outage risks.
- Installations where rights-of-way are limited or visually sensitive.
- Systems requiring enhanced resilience against external contact.
Construction Details:
The tree wire is designed with concentrically stranded conductors. While typically ACSR, it can also be supplied with AAC (1350-H19) or AAAC (6201-T81 aluminum alloy) conductors, which are either compressed or compact depending on the conductor size. The conductors are then covered with either High-density track-resistant Polyethylene (HDTRPE) or track-resistant Crosslinked Polyethylene (XLPE) insulation to meet specific application requirements and provide the three distinct layers of protection.
