DCC Copper Wire (100gm)
Product Code : SCL-PLE-11761
The JLab India DCC (Double Cotton Covered) Copper Wire is a specialized electrical conductor engineered for the construction of inductors, electromagnets, and transformer windings. Optimized for Secondary and University-level physics, this wire features a high-purity copper core insulated with two layers of tightly wound natural cotton. It facilitates the study of electromagnetism and solenoid dynamics where traditional enamel insulation may be prone to mechanical abrasion.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Electromagnetic Interface: Facilitates student visualization of solenoid construction and magnetic field generation (B=μ0nI), supporting Electromagnetism Module 101.
- Inductance Quantification: Enables the physical study of coil winding, allowing learners to apply formulas for self-inductance and mutual inductance in transformer models.
- Insulation Analysis: Supports the analysis of different insulation types; the cotton covering provides excellent oil/wax absorption for creating high-stability "potted" coils.
- Material Conductivity Evaluation: Allows students to evaluate the relationship between wire gauge (SWG), length, and total DC resistance in a wound component.
International Logistics & Compliance
JLab India ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant) featuring moisture-barrier vacuum sealing to prevent the natural cotton fibers from absorbing humidity and degrading during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a table of Resistance per Meter for various SWG gauges.
- Durability: Tropicalized design featuring anti-fungal treatment on the cotton fibers to ensure the insulation does not rot or weaken in high-humidity laboratory climates.
Direct OEM Sourcing Advantages
Procuring JLab India DCC Copper Wire directly ensures vertical manufacturing control:
- Uniform Core Drawing: Every batch is checked for diameter consistency to ensure that the number of turns per layer remains constant in student-built coils.
- Precision Wrapping: The double-layer cotton application is monitored for density and "gapless" coverage, preventing short circuits between adjacent turns in a winding.
- Direct Factory Spares Availability: Guaranteed availability of various gauges to allow for custom transformer and motor-winding projects.
- Manufacturing Control: Direct oversight of the annealing process ensures the copper remains "soft" and easy for students to wind by hand without spring-back or work-hardening.
