Conductor: Class B Compact concentric strand aluminum alloy 1350 or soft drawn annealed copper per ASTM.
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.
Metallic Shield: Helically applied non-magnetic copper tape(s) over the insulation shield followed by a separator tape.
Mechanical Protection: High strength and high crush resistant Air Bag™ Layer extruded over the core.
Chemical Protection: A layer of Drylam® which consists of an aluminum tape a chemical resistant extruded polymer layer is applied.
Jacket: Sunlight resistant polyvinyl chloride (PVC), non-leaded jacket.
