The 3-Layer 25kV AAC Tree Wire Spacer Cable is engineered for primary and secondary overhead power distribution in space-constrained environments. It features a three-layer construction: a concentrically stranded AAC conductor, XLPE insulation, and an outer high-density, track-resistant polyethylene (HDPE) sheath. This robust design provides enhanced mechanical strength, electrical reliability, and resistance to tracking and flashovers.
Ideal for urban, forested, or tight alleyway installations, tree wire spacer cables allow closer conductor spacing and minimize hardware needs compared to traditional bare conductors.
Applications
Tree Wire Spacer Cable is designed for:
-
Overhead primary and secondary distribution lines
-
Urban and forested environments where right-of-way is limited
-
Compact pole configurations in alleyways or narrow corridors
-
Preventing direct shorts and flashovers with tree limbs or foreign objects
-
Use in place of bare conductors for enhanced reliability
Its robust covering allows closer spacing between conductors, reducing installation hardware and visual clutter.
