Product Information

Specification

Prysmian Airguard 250 MCM 3C MV105 8kV 3C EPR/PVC 100% Medium Voltage Power Cable

Application:

• Prysmian’s patented AIRGUARD cable is a direct replacement for continuously corrugated and welded aluminum armored cables (*in Class 1 Div 2 locations) with 5X the impact performance and up to 3X the sidewall bearing pressure limit (at 3000 lbs per rad-ft) This enables longer pulls than with CCW type cables. Please call in regards to the product literature and performance testing and videos.
• Three conductor cable with stranded copper or aluminum conductors, extruded insulation system consisting of a thermosetting semiconducting conductor shield, high dielectric strength EPROTENAX EPR insulation, thermosetting semiconducting insulation shield, helically applied bare copper tape shield, cabled with fillers and grounding conductors, overall binder tape, foamed polymeric AIR BAG™layer for superior mechanical protection, longitudinally applied aluminum tape, extruded oil and hydrocarbon resistant polymeric DRYLAM layer, and overall sunlight resistant PVC jacket. Suitable for Class I Division 2 locations.

Conductors:

Class B Compact concentric strand aluminum alloy 1350 or soft drawn annealed copper per ASTM.

Metallic Shield:

 Helically applied non-magnetic copper tape(s) over the insulation shield with a nominal overlap of 25%. A mylar ribbon is longitudinally applied under the copper tape shield for phase identification - 1C w/ Red, 1C w/ Blue, and 1C w/ Black.

Conductor Shield:

 Extruded thermosetting semiconducting shield which is free stripping from the conductor and bonded to the insulation.

Insulation:

Natural high dielectric strength EPROTENAX™ EPR-based insulation, combined with other materials and agents that enhance the electrical and mechanical characteristics assuring extended cable life.

Insulation Shield:

Extruded thermosetting semiconducting shield with controlled adhesion to
the insulation providing the required balance between electrical integrity and ease of stripping.

Grounding Conductors:

Bare stranded copper conductor per UL, ICEA, and ASTM.

Assembly:

Phase identified conductors cabled with fillers and grounding conductors, forming a firm and cylindrical cable core. A binder tape is applied to maintain core symmetry and mechanical stability.

Mechanical Protection:

High strength and high crush resistant AIR BAG layer extruded over the core assembly.

Chemical Protection:

A layer of DRYLAM which consists of a 6mil longitudinally applied aluminum tape and a chemical resistant extruded polymer layer is applied.

Jacket:

Sunlight and moisture resistant polyvinyl chloride (PVC) jacket.
