2500 MCM High Voltage Round Aluminum Wire and Tape Shield XLPE Insulation HDPE Jacket 115 kV

Application:

• Transmission and distribution circuits, in cities with high load densities. Also, for Industrial and Commercial installations.
• May be installed in wet or dry locations indoors or outdoors in conduit and underground ducts.

Also Known As:

2500 MCM High Voltage Cable, Aluminum Shield Cable, 2500 MCM HDPE Jacket, Aluminum Wire and Tape Cable, 2500 MCM XLPE Shield Cable, Tape Aluminum Cable. 

Standards:

• IEC 60840: Power cables with extruded insulation for rated voltages above 30 kV up to 150 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: Semiconducting cross-linked 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 over the insulation shield.
• Metallic Shield:  Solid, annealed uncoated copper wires per ASTM B3, helically applied and uniformly spaced. A copper tape helically applied over the copper wires, with open helix and water blocking tape.
• Radial Moisture Barrier: A smooth aluminum laminated tape longitudinally applied and bonded to outer jacket.
• Jacket: Black high density polyethylene (HDPE) sunlight resistant thermoplastic compound.
