Construction

Conductors:

Aluminum conductor used for this cable is either a concentric strand or compressed 1350-H19 series aluminum conductor. The conductors are cabled together, with surface printing for identification. The neutral conductor has a yellow stripe. 

Insulation:

Versatile insulation system made of cross linked black polyethylene material helps to secure the cable conductors. This insulation is water tight, repulsive to corrosive substances, resistant to oil, heat and flame. Cross linking a polyethylene helps to achieve an excellent strength that makes the material suitable for covering this cable used in harsh conditions like direct burial installation.
