DPC copper wire is characterized by its insulation made from multiple layers of Insulating Grade Kraft Paper. This insulation method enhances flexibility and strength, making it suitable for high-voltage applications, such as in oil-filled transformers and current transformers. This process increases the elasticity of the paper, allowing it to conform better to various shapes while providing effective insulation and heat dissipation during operation.
