Basic Concepts and Characteristics of Graphene
Definition of Graphene
Graphene is a carbon allotrope forming a 2D plane with hexagonal lattice pattern of carbon atoms, with thickness of 0.2nm~0.34nm as a single atomic layer with high physical and chemical stability.
Chemical Vapor Deposition (CVD)
A single layer of graphene atoms at less than 0.34 nanometers is perfectly deposited on 0.05~0.08 copper wire using chemical vapor deposition (CVD).

Graphene shows 29% better conductivity than silver and 35% better than copper, optimized for audio signal transmission. This superior electrical conductivity minimizes signal loss and greatly improves audio quality when graphene is used as a cable material. The effect is particularly pronounced in high-frequency signal transmission.

Regular Copper Wire and High-Frequency Current Limitations
Skin Effect Principle
High-frequency current concentrates on conductor surface
Conductor Performance Degradation
Reduced effective cross-section and increased resistance
Audio Signal Quality Degradation
Loss and distortion of high-frequency signals
Copper is a metal with excellent electrical conductivity second to silver, widely used in wire manufacturing due to cost efficiency. However, at high frequencies, a phenomenon called the 'skin effect' occurs where current concentrates only on the surface of the conductor. As frequency increases, current flows only in a thinner surface layer, with the interior barely used, resulting in decreased effective cross-sectional area and increased electrical resistance. Audio signals contain various frequencies, and the increased resistance due to the skin effect causes loss and distortion particularly in high-frequency signals, reducing the detail, clarity, and spatial sense of music.
Impact of Graphene Coating on Skin Effect
Surface Conductivity Innovation
Graphene coating creates a path for electricity to flow more efficiently on the copper surface. It moves electrons quickly, improving surface current flow and advantageously utilizing the high-frequency skin effect.
Surface Resistance Reduction
The graphene layer reduces the electrical resistance of the copper surface. It facilitates the movement of electrons when high-frequency current concentrates on the surface, increasing efficiency.
Frequency Response Improvement
Graphene coating provides uniform electrical characteristics at all frequencies. High-frequency performance is enhanced, allowing audio signals to be transmitted without distortion.

How to Distinguish Genuine Graphene CVD from Fake Products
Characteristics of Genuine Graphene CVD
Our cables made with Chemical Vapor Deposition (CVD) use pure graphene certified by Raman spectroscopy. The CVD graphene cable developed with Haesung DS over 10 years reduces resistance by 10% compared to regular cables and significantly improves signal transmission speed.
Problems with Fake Products
Counterfeit products on the market simply coat low-grade graphite powder and fail to provide the excellent conductivity and durability of graphene. They have limited production capacity of less than 100 meters per month with small batch processes, and lack independent verification data on resistance reduction rates and objective performance evidence.
Quality Certification Verification Method
Genuine products must be certified as 'CVD Graphene'. We provide CVD graphene Raman analysis certificates and test data for all cables. "GrapheneSquare", winner of the 2023 CES Best Innovation Award, also produces products using the same CVD method as our company, proving the international excellence of CVD graphene technology.

Increasing Effectiveness
Greater benefits at longer cable lengths
Through joint research with a national university, precise verification results show that as cable length increases, the resistance reduction effect of graphene CVD coating becomes more evident. This matches the 14%~17% resistance reduction rate shown in national university test results, proving the consistency and reliability of graphene CVD coating technology.
