Speed-link coaxial cables are divided into 12 series according to their structure and characteristics (SPT, SPB, Obend, SPO...). etc.) can meet the diverse needs of customers from the global market. Coaxial cables can be divided into baseband coaxial cables and broadband coaxial cables (that is, network coaxial cables and video coaxial cables) from the use. Speed-coupled coaxial cables are divided into two categories: 50Ω baseband cable and 75Ω broadband cable. Working principle of baseband cable Coaxial cable is divided into four layers from the inside to the outside: the center copper wire, plastic insulator, the mesh conductive layer and the wire skin. The current conduction is a loop formed by the central copper wire and the mesh conductive layer. It is named because the central copper wire and the reticular conductive layer are coaxial. Coaxial cables conduct alternating current instead of direct current, which means that the direction of the current is reversed several times per second. If a regular wire is used to transmit high-frequency current, the wire will be equivalent to an antenna that emits radio outward, and this effect dissipates the power of the signal and reduces the strength of the received signal. The radio emitted by the center wire is isolated by a mesh conductive layer, which can control the transmitted radio by grounding.
In the future, we can build customized cables according to the customer's special application support, welcome to inquire!
