shield wire การใช้

• Optical fibers can be included in the stranded conductors of a transmission line, in the overhead shield wires.
• The outer appearance of OPGW is similar to aluminium-conductor steel-reinforced cable ( ACSR ) usually used for shield wires.
• Live-line working techniques are used to re-strand the towers with OPGW replacing the all-metal type of overhead shield wires.
• In last week's action, FAA regulators issued a proposed rule that requires airlines to install equipment to shield wiring from the fuel monitoring system.
• Wrapped cables can be applied to earth wires ( ground wires, shield wires ) on power transmission lines and to phase conductors on transmission, sub-transmission or distribution lines.
• There are two variants of wrapped optical fibre cable systems for installation on overhead electricity power lines : they differ in the nature of the host earth-wire ( also known as ground-wire or shield wire ) of the overhead line.
• Medium-voltage distribution lines may also use one or two shield wires, or may have the grounded conductor strung below the phase conductors to provide some measure of protection against tall vehicles or equipment touching the energized line, as well as to provide a neutral line in Wye wired systems.
