15kv Covered Aerial 3 Layer Cable Spacer Cable Tree Wire
The conductor material can be AAC AAAC ACSR etc.
XLPE covered cable is constituted by a compact round conductor, composed by aluminum strands, blocked or not, with
a cross-linked polyethylene (XLPE) covered black or gray color.
The XLPE covered aluminum cable- 25kV Voltage Class is constituted by a compact round conductor, composed by alu
minum strands, blocked or not, and with a cross-linked polyethylene (XLPE) covered in black or gray color, with special
characteristics to be resistant against electric tracking and UV-rays.
As XLPE is a thermoses material, it enables operation up to 90°C continuously implying in higher capacity when compar
ed to the thermoplastic materials.
The main application for covered aluminum cables is on compact overhead, primary power distribution, medium-voltage
networks located in urban and wooded areas. These cables are an excellent technical and economic option for compan
ies all over the world, since they feature such advantages as low manufacturing cost and ease of installation.
