Vertical riser cable is steel wire armored power cable for vertical runs in a building.
Vertical riser cable is power cable, armored with steel wire, designed for vertical runs that rise through the floors of a building. When cable runs vertically over a substantial height, its own weight creates tension along its length, and the steel wire armor provides the strength to support that weight as well as mechanical protection. This makes vertical riser cable suited to carrying power up through the risers of a multistory structure.
Because the steel armor bears the cable's weight on a vertical rise, it allows the cable to be supported and installed in tall vertical runs that would overstress an unarmored cable. The armor also protects the conductors from mechanical damage along the route.
In commercial and industrial buildings, vertical riser cable carries power between floors through vertical shafts and risers. Recognizing the term helps in understanding cable built to handle the demands of vertical installation.
Because the steel armor bears the cable's weight on a vertical rise, it allows the cable to be supported and installed in tall vertical runs that would overstress an unarmored cable, while the armor also protects the conductors from mechanical damage along the route through a building.
At Windy City Wire, an understanding of cable constructions, including armored vertical riser cable, supports the selection of cable suited to its installation. Recognizing how steel wire armor supports a cable's weight on a vertical rise helps illustrate the range of constructions available for commercial and industrial buildings.
