Transformer Riser Wire
Transformer riser wire is used in various uninsulated transformer applications. The HMWPE covering surrounding the copper conductor is not electrical insulation, but protects the wire from faults caused by weather, vibrations, and crossed leads.

Sunlight Resistant Direct Burial Rated Corrosion Resistance Oil & Gas Resistant Although its HMWPE insulation should not treated as an insulation, the covering on transformer riser wire does reduce faults caused by atmospheric conditions, shorts caused by excessive vibrations, and faulting caused by objects crossing the leads.
