UL20251
A telephone cord is an essential cable designed for telephones and various electronic devices, widely used in telephone connection lines, handset wiring, and internal signal transmission systems. Engineered with high-quality materials and compliant with international safety standards, this corded phone cable ensures stable, secure, and long-lasting performance in both residential and commercial environments.
Manufactured using stranded or solid conductors made of tinned copper, bare copper, or tinsel, the telephone cord is combined with color-coded polypropylene (PP) insulation and a robust PVC telephone cord sheath. This structure guarantees excellent electrical conductivity, strong insulation performance, and superior durability for everyday use.

This phone cord supports 2 to 10 conductors arranged in a parallel flat structure, making installation neat and efficient. The cable is designed to withstand regular bending and handling, making it ideal as a telephone handset cord, modular telephone cord, or internal cable for electronic equipment.
