WW Medium voltage HDPE sheathed cables are mostly used as feeder electric cable for power distribution networks where moisture penetration or heavy abrasion resistance is required. They are suitable for fix installation indoors, outdoors, in underground and dry/damp areas.
Voltage Ranges: 11kV - 33kV
Conductor operating temp: -25oC - 90oC
Emergency conductor temp: 105oC
Short circuit temp: Max 250oC for 5 sec
Minimum ambient temp: -25oC after installation and only when cable is in a fixed position
Minimum bending radius: 25xcable O.D during installation 15xcable O.D after installation
Maximum pulling tension: 70N/mm2 x total cross-sectional area of phase conductor
Phase conductor: plain annealed copper, class 2 compact stranded to reduce the cable diameter and cost, complying with AS/NZS 1125
Phase core: triple extruded semi conductive conductor screen, crosslinked polyethylene (XLPE) insulation and semi conductive insulation screen to AS/NZS 3808
Metallic screen: copper wires screen provides high conductivity for faulty current as earth wires. (Plain annealed copper wire has a minimum diameter of 0.85 mm) Water-swellable tape collectively applied over the metallic screen
Interstitial filler: for three-core cable only, non-hydroscopic material
Bedding: Flame retardant 90 oC heavy duty polyvinyl chloride (PVC)
Sheath: High density polyethylene (HDPE)
