Classification and use of twisted wires

edit

Ordinary stranded wire:

Aluminum stranded wire (LJ): advantages: light conductor, good conductivity. Uses: It is used for distribution lines of overhead power lines with less force.

Hard copper stranded wire (TJ): advantages: superior electrical performance; use: overhead transmission lines.

Aluminum alloy stranded wire (LHAJ): advantages: high tensile strength, electrical conductivity is 10% lower than aluminum stranded wire. Uses: glaciers, mountains, hills and other places.

Aluminum clad steel stranded wire: advantages: high tensile strength. Uses: Long-span lines. Combination twisted wire:

Steel core aluminum stranded wire (LGJ): advantages: high tensile strength. Uses: overhead transmission lines, distribution lines, heavy ice areas and long-span transmission lines.

Anti-corrosion steel core aluminum stranded wire: Advantages: Prevent the steel core from corrosion and increase the service life of the wire. Uses: saltwater lakes, coastal areas, industrial and mining areas and areas with severe corrosive atmosphere.

Aluminum clad steel core aluminum stranded wire: Advantages: Prevent corrosion of steel core and increase the service life of the wire. Reduce line loss. The unit weight is reduced, and the lead span is increased.

Special stranded wire:

Expanded steel core aluminum stranded wire: advantages: increase the outer diameter of the wire, save non-ferrous metals, and reduce corona loss. Uses: high voltage power transmission and high altitude power transmission.

Expanded hollow conductor: advantages: it has a larger outer diameter of the conductor, reduces corona loss, and saves non-ferrous metals. Uses: high-voltage substation.

Vibration damping and gap type stranded wire: advantages: each stranded layer is separated, which can reduce vibration by itself. Uses: in stormy areas.

Anti-icing stranded wire: advantages: strong anti-icing and snow resistance. Use: Heavy ice zone.

Copper brush wire: advantages: stable structure, good softness, using stranded and re-stranded. Uses: Lead wires in motors.

Bare copper flexible stranded wire: Features: It adopts regular stranding, bundle stranding, no re-stranding, or regular stranding and re-stranding after bunching. Uses: Connect motor, electrical equipment components.

Copper braided wire: Pros: The wire is soft. Uses: Connection cables for mobile electrical equipment, also used to connect batteries for automobiles and tractors.

Aluminized steel core aluminum stranded wire: Features: Galvanized steel wire changed to aluminized steel wire. Increase corrosion resistance. Uses: used for anticorrosive lines.

Weather-resistant insulated overhead line: Features: Add insulation layer on the surface of LJ and LGJ stranded wire. Use: The line is used through forest areas and cities.

Conductive wire core: Features: Mostly power cables with oil-impregnated paper insulation and plastic insulation. Hard wire core: used for marine cables, power cables, etc. Flexible core: used in mining cables, rubber sheathed cables, etc.

Extra-flexible cables: use frequently moving wire and cable cores and conductive wires and cables with special requirements.
