BS 215 Part 1 Bare AAC All Aluminium Conductor Power Transmission
DOWNLOAD CATEGORY SPECIFICATIONS
Application
AAC conductors are also called aluminium stranded conductors.This British Standard applies to stranded all aluminium conductor AAC for overhead power transmission.
Aerial conductors on transmission&distribution lines are often specified where there is significant distance to cover and where these cables are best positioned far out of reaching. The distances to be covered, the environmental conditions it will be up against, and the location are made of all factors in specifying the compatible cables.
Bare AAC Cable is most commonly used in urban areas with frequent supports and short spans. They are also used in coastal regions where salt in the air can cause corrosion but the aluminium wires have its good performance of corrosion resistance.They are specified for use in the railway industry for OHL electrification.
Advantages
Aerial bare conductors AAC have its excellent lightweight properties. These overhead lines have no specified voltage rate and it will depend on the type of installation.
Construction
Aluminum 1350-H19 wires, concentrically stranded, successive layers having an opposite direction of lay, the outermost layer being right-handed.
1. Aluminum 1350-H19 wires
Packing
Delivery lengths are determined from a consideration of such factors as physical drum dimensions, drum weights, span length, handling equipment or the customer’s request.
Packing Materials
Wooden drum, steel-wooden drum, steel drum.
