Submersible Winding Wire

Home / Quality

⚙️ Mechanical Properties

  • High Tensile Strength: Can handle mechanical stress during motor winding and operation.
  • Flexibility: Allows for tight and compact windings.
  • Abrasion Resistance:Resists damage during assembly and operation in harsh conditions.

🔌 Electrical Properties

  • Excellent Conductivity: Pure copper ensures low resistance and high efficiency.
  • High Insulation Resistance:> Prevents leakage current and short-circuits even when submerged.

🌊 Moisture & Water Resistance

  • Double/Triple Insulation: Often features multiple layers of waterproof insulation (PVC, rubber, or special thermoplastics).
  • Hydrolysis Resistance:Insulation resists breakdown from long-term exposure to water.
  • Submersible-Grade Insulation: Designed to prevent water ingress even under high pressure.

🔥 Thermal Properties

  • Heat Resistance: Can handle temperatures typical of submerged motors (often up to 130–155°C or more depending on insulation).
  • Thermal Shock Resistance: Withstands sudden changes in temperature.

🧪 Chemical Resistance

  • Oil and Chemical Resistance: Insulation resists attack from oils, greases, and other chemicals found in pumping environments.
  • Corrosion Resistance: Copper and its insulation are protected from chemical corrosion.

✅ Common Standards & Features

  • IS 8783 / IS 13730: Indian Standards for submersible winding wires.
  • RoHS Compliance: Often free of hazardous substances.
  • Available in Round or Flat Profiles: Flat wires are common in large HP submersible pumps.

🔁 Comparison with Standard Enameled Wire:

Quality Assurance

Submersible Winding Wire

We strictly adhere to international standards like IS, IEC, and NEMA. Each product undergoes rigorous quality checks to ensure electrical integrity, mechanical strength and long-term reliability. Our ISO-certified processes guarantee consistency across every batch.

Submersible copper winding wire is specially designed for use in submersible motors and pumps, where it must operate underwater or in moist environments. It differs from standard enameled copper wire by having extra insulation and enhanced durability to withstand water, pressure, and heat.
