Three Conductor MV105 5kV EPR/PVC 133% Medium Voltage Power Cable

Application:

• Aerial installations
• Open trays
• Direct buried 
• Metal racks
• Open trays
• Troughs or raceway
• These cables are capable of operating continuously at a maximum conductor temperature of 105°C for normal operation, 140°C for emergency overload conditions, and 250°C for short circuit conditions, and are rated at 5,000V, 100% (grounded system) and 133% insulation levels (ungrounded system).

Scope:

This specification covers three conductor EPR (ethylene propylene rubber) insulated, shielded, thermoplastic jacketed power cables with grounding conductor for use in aerial installations, metal racks, open trays, troughs, or continuous rigid cable supports. These cables are capable of operating continuously at a temperature of 105°C for normal operations, 140°C for emergency overload conditions, and 250°C for short circuit conditions, and are rated at 5,000V, 100% (grounded system) and 133% insulation levels (ungrounded system).

Also Known As:

MV105 Cable, Medium Voltage Power Cable, Power Cable, EPR/PVC Cable, MV105 Power Cable, MV105 EPR/PVC Cable.

Construction:

Conductors: 

The conductor shall be Class B compressed concentric stranded bare copper in accordance with ASTM Specs B3 and B8 and ICEA Part 2, Section 2.1 and 2.5

Conductor Shield:

The conductor shall be shielded with an extruded semi-conducting thermosetting polymeric layer, which shall be firmly bonded to the insulation. The thickness shall be in accordance with the referenced standards.

Insulation:

The insulation shall be EPR (ethylene propylene rubber) meeting the requirements of the referenced standards. The average thickness shall be 0.090" and the minimum spot thickness shall be not less than 90% of the average thickness

Insulation Shield:

The insulation shall be shielded with an extruded semi-conducting thermosetting polymeric layer which shall be identified as being semi-conducting. Over this layer shall be applied a helically wrapped 5-mil copper tape.

Grounding Conductor:

The ground conductor shall be Class B compressed concentric stranded bare copper in accordance with ASTM B3 and B8.

Assembly:

The insulated and shielded power conductors shall be cabled round with fillers and with a grounding conductor in one outer interstice and covered with a binder tape.

Jacket:

The cable shall be covered with a black PVC jacket conforming to the requirements specified for polyvinyl chloride in ICEA. The average thickness shall be in accordance with the referenced standards and the minimum spot thickness shall be not be less than 80% of the average thickness. The jacket will be sunlight resistant and will meet the requirements of the IEEE 1202
