Product Overview:
Designed for modern overhead distribution, the 2-Layer 15kV AAC Tree Wire Spacer Cable facilitates safe and efficient power transmission in congested areas. Unlike bare conductors, its multi-layered covering is highly effective in preventing outages caused by accidental contact with trees, animals, or other objects. The close-proximity configuration minimizes the footprint required for line installation, making it an ideal choice for urban alleyways, tight corridors, and areas with dense vegetation.
Applications:
This specialized cable is perfectly suited for primary and secondary overhead distribution systems in situations demanding high reliability and reduced clearance requirements:
- Congested Urban Areas: Ideal for power lines running through narrow spaces, such as city alleyways, where traditional bare conductors are impractical or unsafe.
- Tree-Lined Streets: Provides superior protection against accidental contact with tree branches, significantly reducing the risk of power outages and fires.
- Environmentally Sensitive Areas: Minimizes the visual impact and physical footprint of overhead lines, integrating better with landscapes.
- Wildlife Protection: The insulated layers offer a deterrent against wildlife-induced outages.
Construction:
The 2-Layer 15kV AAC Tree Wire Spacer Cable is engineered for maximum performance and durability:
- Conductor: Features concentrically stranded conductors made from AAC (1350-H19) aluminum, which are either compressed or compact depending on the specific conductor size. Options with AAAC (All Aluminum Alloy Conductor) or ACSR (Aluminum Conductor Steel Reinforced) are also available to meet varying strength requirements.
- Insulation Layers: The conductors are meticulously covered with multiple layers of insulation. The primary insulation is Cross-linked Polyethylene (XLPE), known for its excellent electrical properties and thermal resistance.
- Sheath/Outer Covering: The outermost layer consists of High-density Track-Resistant Polyethylene (HDTRPE), specifically designed to resist tracking (the formation of conductive paths on the surface) and enhance durability against environmental factors and abrasion.
