25kV AAC Tree Wire
What is 25kV AAC Tree Wire？
25kV AAC 3 Tree Wire layers are concentrically stranded conductors, which come in compressed or compact formats depending on their size. These conductors can be insulated with high-density track resistant polyethylene (HDTRPE) road-resistant cross-linked polyethylene (XLPE) to adapt to various needs and applications.

Tree Wire Applications
25kV Tree Wire Used for primary and secondary aerial distribution in scenarios where space must be conserved or where narrower rights-of-way are preferred. Its installation mirrors that of bare conductors, but its cover serves as crucial protection against direct short circuits and instantaneous discharges with nearby objects. Proximity design reduces space and hardware required for line installation, which is especially beneficial in densely populated areas such as alleys or narrow passages.
