ASTM 25kV SAC Cable System is used for primary or secondary overhead allocations with limited space available
This SAC Cable is suitable for voltages up to 25,000 volts.
This tree wire is insulated to prevent direct short circuits and momentary flashovers if climbing trees or other objects come into contact with such close conductors.
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:
AAC (1350-H19, compact 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 low-, medium- or high-density polyethylene covering (LDPE, MDPE or HDPE), where the outer layer is track-resistant (TK-MDPE or TK-HDPE). All layers are bonded together. The outer layer shall be black or gray, sunlight resistant and track resistant.
These cables 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 B400 – Compact Round Concentric-Lay-Stranded Conductors
- ASTM D1248 – Polyethylene Plastics Extrusion Materials for Wire and Cable
- ICEA S-121-733 – Tree Wire and Messenger Supported Spacer Cable
