Hv ABC Cable, Aerial Bundled Cable, Al/XLPE+AAAC, 3/C+1/C, 12.7/22 Kv (AS/NZS 3599.2)

HV ABC Cable, Aerial Bundled Cable, Non Metallic, 12.7/22 kV (AS/NZS 3599.2)
Non Metallic Screened HV ABC

Conductors
Phase conductors are stranded circular compacted aluminium alloy 1350 to H68 condition. The standard catenary is bare stranded circular compacted aluminium alloy 1120 conductor. For special applications, such as high wind locations, aluminium-clad steel-reinforced catenaries are available.

Conductor Screen, Insulation and Insulation Screen
Semiconductive conductor screen, XLPE insulation and semiconductive insulation screen are triple extruded. The insulation screen is hand strippable without preheating and complies with strippability and adhesion tests given in AS/NZS 3599.2. Figures and words "1 ONE," "2 TWO" and "3 THREE" are marked on the insulation screen to identify the three phase cores.

We has developed a special Non Metallic Screened HV ABC with far greater resistance to damage from abrasion during installation or due to brushing with trees. This special cable has a semiconductive HDPE layer over the hand-strippable insulation screen, providing less risk of damage during installation and service.


The cable bundle
The three single core cables are bundled around the aluminium alloy 1120 catenary in a right hand lay. Operating temperatures
(a) Normal operation 90°C
(b) Emergency operation 105°C
(c) Short circuit operation 250°C (5s max)
