D.P.C (Wire / Strip) S.E.M. Wire (Aluminium / Copper)

Mayank Vidut is proud to introduce its expert services in supplying premium-quality DPC (Double Paper Covered) wires and strips, along with S.E.M. (Super Enamelled) wires in both aluminum and copper. These products are crafted for top-tier electrical applications—transformers, motors, generators, inverters, and more. Our offerings combine precision, reliability, and longevity for unmatched performance.

What is DPC Wire and Strip ?

DPC stands for Double Paper Covered wire. It refers to a solid copper or aluminum conductor wrapped with two layers of insulating kraft paper, each layer applied in opposite directions to ensure airtight insulation and mechanical strength

Key Features:

  • High Electrical Insulation – Two kraft paper layers prevent current leakage.

  • Mechanical Strength & Flexibility – Especially when using crepe kraft paper.

  • Custom Sizes – Conductors range from 1 mm to 5 mm diameter (round) and strips up to 75 sq mm

Applications:

  • Transformer windings (LT & HT)

  • Current & voltage transformer leads

  • Oil-cooled transformer windings

  • Inductive devices like chokes and reactors

Why Choose DPC Wire ?

  • Safety & High Insulation
    The dual paper layer system offers durable insulation, heat resistance, and protection against mechanical stress.

  • Durability & Reliability
    Crepe kraft paper adds flexibility and strength, especially in shaped coils.

  • Consistent Thermal Performance
    DPC wire withstands transformer oil, heat, and aging, maintaining its performance even under high stress.

  • Versatility
    Ideal for electrical machinery of various ratings—from distribution transformers to high-voltage applications.

What Is SEM Wire ?

S.E.M. wire, or Super Enamelled (varnished) wire, is a conductor coated with a durable varnish applied at high temperature. It comes in aluminum or copper.

Features:

  • Smooth, insulating varnish coating with excellent dielectric strength.

  • Varnish types like Terebec or Isomelt polyester, rated as Class C insulation for high heat resistance .

  • Available in round wire (0.3 – 5 mm) and strip form (0.5 – 4 mm thick) .

Typical Applications:

  • Transformer windings

  • Motor coils

  • Generator and inverter components

  • Precision inductive devices
