1250 MCM Extra High Voltage Round Aluminum Cable Al Shield/Sheath XLPE Insulation HDPE jacket 230 kV

1250 MCM Extra High Voltage Round Aluminum Cable Al Shield/Sheath XLPE Insulation HDPE jacket 230 kV

Application:

• Transmission systems in urba and industrial installations with high load density.
• May be installed in wet or dry locations indoors or outdoors in conduit and underground ducts.

Also Known As:

1250 MCM High Voltage Cable, Aluminum Shield Cable, 1250 MCM HDPE Jacket, Aluminum Shield/Sheath Cable, 1250 MCM XLPE Shield Cable, Aluminum Cable. 

Standards:

• IEC 62067: Power cables with extruded insulation and their accessories for rated voltages above 150 kV up to 500 kV.
• AEIC CS9: Specifications for extruded insulation power cables and their accessories rated above 46 kV through 345 kV.
• ICEA S-108-720: Standard for extruded insulation power cables rated above 46 kV to 345 kV.

Features:

• True triple vertical extrusion system for optimum insulation concentricity, and excellent
electric field control.
• Dry cure process.
• Closed handling of raw materials system to eliminate any contact with ambient, until extrusion process ends.
• Low dielectric losses.
• Metallic shield for ground connection.
• Sunlight resistant jacket.

Construction:

• Conductor: 1350-H19 Aluminum, Class B or Class 2 filled stranding compacted round or segmental as per ASTM B400 or IEC 60228.
• Semiconducting Tape:  A semiconducting tape may be applied helically with an overlap, as required.
• Conductor Shield: Super smooth semiconducting crosslinked polyethylene.
• Insulation: High quality, heat, moisture, ozone and corona resistant, cross-linked polyethylene (XLPE). 
• Insulation Shield: Semiconducting cross-linked polyethylene.
• Water Barrier: Semiconducting water blocking tape, helically applied.
• Metallic Shield/Sheath: Welded smooth aluminum tape longitudinally applied over semiconducting water blocking tapes.
• Jacket: Black high density polyethylene (HDPE) sunlight resistant thermoplastic
compound.
