STANDARD:ASTM B230, B231, B232, B398, B399, B400
VOLTAGE:5kV, 15kV TP (For Treed Areas), 15kV (For Non-Treed Areas), 25kV, 35kV, 46kV
Covering prevents faults due to contact
Proprietary, high density outer layer resists abrasion and electrical tracking
High impulse strength allows for close spacing of phase conductors
Installed the same as bare conductors, however, covering is effective in preventing direct shorts and instantaneo
AAC (1350-H19), AAAC or ACSR conductors, concentrically stranded. Available with black or gray track resistant, high-density polyethylene (HD) or black track-resistant crosslinked polyethylene (XLP) covering. Covered conductors consist of stranded hard drawn aluminum conductors with either one, two or three extruded layers depending on the voltage rating.
In a Covered Aerial MV System (formerly called Spacer Cable), spacers hold three MV phase conductors in close approximation. The spacers are suspended from a high-strength messenger wire. Covered Aerial MV (CAMV) cable itself is a single aluminum conductor protected by a layer of track-resistant polyethylene.
