Conductor diameter 1.4mm. composite shielded, steel tape armour, PE insulation and outer-sheath. Rated voltage 600/1000V
Overview
The diameter of conductor is 1.4mm. It is composite shielded cable with PE insulation, composite sheath, steel tape armour, and PE outer-sheath. The rated voltage of cable is 600/1000V.
Structure
1) Conductor
The conductor shall be solid circular and formed from plain annealed copper as per IEC 60228.
2) Insulation
The insulation shall be PE.
3) Cable core group
It consists of triple-core with extruded inner sheath. There are three colours: red, white, and blue for identification.
4) Laying up
Inter-twist uniformly by triple sets and insulated single wire. The cable core groups shall be laid up with a right-hand direction. The interstices shall be filled with suitable non-hygroscopic fillers to give the completed cable with a substantial circular cross-section. A layer polyester tape shall be shall be applied around the cable cores.
5) Screen
AL-Plastic laminated composite tape shall be sufficient to provide reduction factor not more than 0.3 with field strength of 100 V/Km.
6) Bedding
The cable core shall be covered with extruded PE bedding which shall be formed tightly around the cable screen, which complies with requirement of IEC 60502.
7) Armour
The armour shall consist of two layers of steel tape applied helically.
8) Over-sheath
An over-sheath of single extrusion PE with termite-proof material shall be applied around the armour steel tapeas perIEC 60502.
