PRODUCTSMedium Voltage Cables to JIS C 3606-2003
Three Core Cables
Application:
This product is used for an underground distribution cable for the lead-out parts of substations of general power distribution lines including high-capacity power distribution, cable tunnels, pipelines, directly embedded types, raising parts of telephone poles, etc.
Standards:
JIS C 3606-2003 (6600V)
Construction:
Conductor: Plain annealed copper with JCS C 3102.
Conductor Screen: The conductor screen consists of an extruded layer of non metallic, semi-conducting compound firmly bonded to the insulation to exclude all air voids.
Insulation: XLPE.
Insulation Screen: The insulation screen consists of an extruded layer of non metallic, semi- conducting compound extruded over the insulation. The extruded semi-conducting layer shall consist of bonded or cold strippable semi-conducting compound capable of removal for jointing or terminating. As an option, a semi-conducting tape may be applied over the extruded semi-conducting layer as a bedding for the metallic layer. The minimum thickness is 0.5 mm. The screen is tightly fitted to the insulation to exclude all air voids and can be easily hand stripped on site.
Metallic Sreen: By sufficiently winding of a soft copper tape on an external semiconductive layer, each core shall be shielded,the tape is wound with overlapping about one-sixth of its width or the equivalent of that.
Over Sheath: Black, PVC or PE.
Identification of wire cores:Wire core identification shall be performed with 3 colors, that is, white, red and blue.
PHYSICAL PROPERTIES:
Operating Temperature: up to 120°C
Cold Resistant: -15 ± 0.5 °C
Three Core 6600V (Test Voltage=17KV)
