Hv ABC Cable, Aerial Bundled Cable, Al/XLPE/Cws/HDPE+Gsw, 3/C+1/C, 6.35/11 Kv (AS/NZS 3599.1)

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 3599.1. Figures and words "1 ONE," "2 TWO" and "3 THREE" are printed on the insulation screen to identify the three phase cores. Alternative identification means are available on request.
A water swellable textile tape is applied over the insulation screen to prevent longitudinal ingress of moisture in the event of damage to the outer sheath.

Metallic Screen
The metallic screen comprises a layer of helically applied copper wires. For short circuit protection, two types of screens, a light and a heavy duty, are available. A separator tape to prevent the penetration of sheath material between the screen wires is applied over the metallic screen. On this design of cable it should be noted that the screens of individual cores are not in direct contact with each other and therefore the fault current level is limited.
 
Sheath
High density polyethylene (HDPE) is used as the standard outer sheath of each phase core. In addition to the identification on the cores, the sheaths of each phase cable are marked with phase numbers matching those of the cores. 

The cable bundle
The three single core cables are bundled around the galvanised steel catenary in a right hand lay.

Operating temperature
(a) Normal operation 90°C
(b) Emergency operation 105°C
(c) Short circuit operation 250°C (5s max)
This cable can be used for aerial as well as underground installations.
