Conductors: Solid or Class B Compressed 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: Solid bare copper wires, helically applied and uniformly spaced.
Jacket: Black, insulating, sunlight resistant, linear low density polyethylene encapsulating the neutral wires with three extruded red stripes and NESC lightning bolt symbol.
