A Multi Core Computer Cable is a specialized cable composed of multiple independent conductors, designed for reliable data, signal, and low-voltage power transmission in computer systems and electronic equipment. Also known as a multicore computer cable, it is widely used where stable signal integrity and strong anti-interference performance are required.
This cable features high-quality copper conductor computer cable construction, combined with aluminum-Mylar shielding and copper braided shielding, effectively reducing electromagnetic interference (EMI) and radio frequency interference (RFI). With its optimized structure, it performs as a computer signal cable, computer control cable, and multi core data cable in demanding environments.

The Multi Core Computer Cable is manufactured using tinned or bare stranded copper conductors for excellent electrical conductivity and flexibility. Each conductor is insulated with color-coded PVC, SR-PVC, or PP insulation, allowing easy identification during installation and maintenance.
Cores are cabled together under an aluminum Mylar shield, with a tinned or bare copper drain wire placed between the Mylar layer and the braided shield. This advanced shielded multi core cable design significantly improves noise suppression and signal stability. A durable PVC jacket provides mechanical protection and long service life.
