The Self-bearing Isolated Wires (SBIW) are intended for application in air-lines of an electricity transmission (high voltage line) with a suspension bracket on support or facades of buildings and constructions.
Climatic modification — UHL, categories of placement — 1, 2 and 3.
Types of the self-bearing isolated wires: SIP-1 of SIP-1A of SIP-3 of SIP-2 SIP-2Akonstruktion:
1. A phase conducting vein from aluminum, multiwire, condensed.

2. The zero bearing vein from an aluminum alloy of ABE or steel-aluminum, multiwire, condensed.

3. Isolation:
svetostabilizirovanny polyethylene (LDPE) for wires
SIP-1, SIP-1A
svetostabilizirovanny polyethylene (XDPE) for wires
SIP-2, SIP-2A, SIP-3

Advantages HOARSED:
at equivalent capital investments, the high voltage line with the VULTURE demand smaller operational costs; a possibility of a joint suspension bracket on support of wires with the different level of tension and with phone lines; reduction of safe distances to buildings and other engineering constructions (electric, telephone, air-lines); height over earth level — 4 meters, for uninsulated wires — 6 meters; the possibility of short circuit between wires of phases or on the earth is excluded; an exception of danger of emergence of the fires in case of falling of wires on the earth; high safety of service — absence of risk of defeat at a contact of the phase wires which are energized; the smaller weight and big duration of sticking of snow, the increased reliability in zones of intensive icing, reduction of ice and wind loads of support; decrease in power failure owing to small jet resistance; reduction of volumes of emergency recovery operations; simplicity of repairs, especially during the works energized; decrease in probability of plunder of the electric power and destruction of the high voltage line; safety of works near the high voltage line
