Coaxial Cables
In the mid-1930s, to support the rapid expansion of telephone services and the emerging demands of television transmission, AT&T Laboratories developed coaxial cables consisting of a central conductor, insulation, an outer conductor, and a protective jacket. In 1999, Pacific Electric introduced advanced high-foam insulation extrusion equipment from overseas, expanding its coaxial cable product line from large 1-5/8″ low-loss cables to compact 1.5D coaxial cables, and delivering high-quality solutions to meet diverse customer requirements.
Key Features
Cable Structure
Center Conductor
Typically made of copper, responsible for transmitting data and video signals.
Dielectric Insulation
A plastic insulation layer surrounding the conductor.
Outer Conductor (Shield)
A braided copper shield that protects against electromagnetic interference (EMI).
Outer Jacket
A plastic sheath that prevents mechanical damage.
Impedance Types
75 Ohm
- Primarily used for video signal transmission.
50 Ohm
- Commonly applied in data transmission and wireless communications.
