2-Layer/3-Layer Tree Wire 15KV/25KV

Release time:2021-05-15

Application:
The tree wire is used for primary and secondary overhead distribution where limited space is available or desired for rights-of-way. Installed the same as bare conductors, however, covering is effective in preventing direct shorts and instantaneous flashovers with other objects. The close-proximity configuration minimizes the amount of space and hardware required for line installation, making it particularly useful in congested areas such as alleyways or tight corridors.

Construction:
The tree wire is designed with concentrically stranded conductors - AAC (1350-H19) which are either compressed or compact depending on conductor size, available with AAAC or ACSR. The conductors can be covered with high-density track-resistant Polyethylene (HDTRPE) or track-resistant crosslinked Polyethylene (XLPE) insulation to meet different applications.

Applicable conditions:
1. Long-term allowable working temperature of cable conductor: PVC and polyethylene insulation should not exceed 70℃; cross-linked polyethylene insulation should not exceed 90℃.
2. The laying temperature of the cable is not lower than -20℃.
3. The allowable bending radius of the cable: if the cable outer diameter (D) is less than 25mm, it should be no less than 4D; if the cable outer diameter (D) is 25mm and above, it should be no less than 6D.

Specifications:
15KV/25KV covered multi-layer tree wire meets or exceeds all applicable ICEA specifications and the following ASTM specifications

Certificates:
International: IEC 60502, IEC 60228
China: GB/T 12706.1-2008
