15kV Aerial Electrical Cable for primary and secondary overhead assignments where space is limited or right-of-way is required. Installed as an uninsulated conductor;
However, the covering is effective against direct short circuits and momentary flashovers should tree branches or other objects touch the conductors in such close proximity. The resulting close-in configuration minimizes the space and hardware required for line installation; especially useful in congested areas such as alleyways or narrow corridors.
Single cable with an ACSR conductor, a 3-layer extruded shield and covering system, consisting of an extruded semiconducting thermoplastic conductor shield, and a 2-layer covering. The covering inner layer is a low-, medium- or high-density polyethylene (LDPE, MDPE or HDPE), while the outer layer is track-resistant medium- or high-density polyethylene (TK-MDPE or TK-HDPE). All layers are bonded together.
-Conductor:
ACSR (concentric stranded).
-Conductor Shield:
Extruded semiconducting thermoplastic shield which is free stripping from the conductor and bonded to the covering.
-Inner and Outer Covering:
2-layer crosslinked polyethylene covering (XLPE), where the outer layer is track-resistant (TK-XLPE). All layers are bonded together. The outer layer shall be black or gray, sunlight resistant and track resistant.
These medium aerial cable ACSR 3-layer Track-resistant PE are manufactured and tested to meet or exceed the following standards:
-ASTM B230 – Aluminum 1350–H19 Wire for Electrical Purposes
-ASTM B231 – Concentric-Lay-Stranded Aluminum 1350 Conductors
-ASTM B232-Concentric-Lay-Stranded Aluminum Conductors,Coated-Steel Reinforced (ACSR)
-ASTM D2656 –Cross-linked Polyethylene Insulation for Wire and Cable Rated 2001 to 35000V
-ICEA S-121-733 – Tree Wire and Messenger Supported Spacer Cable
