Single Core 26/35KV Aluminium Tape Armoured Cable Application

The single core cables are designed for distribution of electrical power with nominal voltage Uo/U ranging from 3.8/6.6KV to 19/33KV and frequency 50Hz.

They are suitable for installation mostly in power supply stations, indoors and in cable ducts, outdoors, underground and in water as well as for installation on cable trays for industries, switchboards and power stations.


Single Core 26/35KV Aluminium Tape Armoured Cable Standard 

BS 6622, IEC60502-2, BS 7835 (LSZH Version)

CONSTRUCTION :

Conductor: Plain annealed stranded compacted circular copper or aluminium conductor to IEC60228 class 2

Conductor Screen: Extruded semi-conductive compound

Insulation: XLPE (cross-linked polyethylene) rated at 90°C

Insulation Screen: Extruded semi-conductive compound

Metallic Screen: copper tape or a concentric layer of copper wires

Color for core identification: Red, Yellow ,Blue tape shall be applied between insulation screen and metallic screen ( The above identifying can be changed as user requirement)

Assembly : Three screened cores are laid up together ,if necessary filled with non-hygroscopic material compatible with insulation and covered with a layer of PVC sheath

Inner Sheath: Extruded layer of PVC ST2 or PE , LSZH

Armour : Double of aluminium tape or aluminium wire for single power cable ,Double of galvanized steel tape or galvanized steel wire for three core power cable ,

Outer Sheath: PVC type ST2 to IEC 60502 or PE ,LSZH
