Product Description

Product Description

 

  Paper-covered stranded wire may refer to stranded wire with paper as the insulating material.Strands are often used to increase flexibility and conductivity.Stranded wire is usually made by twisting multiple thin wires together, which increases flexibility. The outer layer is wrapped in paper as insulation.

Application

 

         Transformers: Widely used in windings due to effective insulation and thermal management. Oil-impregnated paper prevents moisture ingress and enhances cooling.

         High-Voltage Cables: Historical use in underground/submarine cables; modern alternatives like XLPE are more common but paper persists in niche applications.

         Historical Installations: Found in older electrical systems where retrofitting with modern materials is impractical.
