Telecommunication Cable: Designed to transmit telecommunication signals such as voice, data, and images, it uses copper exclusively as the conductor. The line voltage typically remains within tens of volts, classifying it as a low-voltage cable. Its structure is unique-internal insulated wires are twisted in pairs to form a pair group, minimizing interference between wire pairs. Every 25 pairs constitute a basic unit, and large cables generally consist of multiple such units. Functionally, it is further categorized into: computer instrumentation cable, high-pair-count telephone cable, twisted-pair network cable, coaxial cable, and flexible signal cable.
Model Name | Core Features | Application Scenarios
DJYPVP | Twisted pair with individual shielding + overall shielding, strong anti-interference capability | DCS systems, 4–20mA instrument analog signals
RVVP | Shielded flexible cable with multi-strand soft core and overall shielding, no twisting | Sensor, alarm, access control switch signals
HYA | High-pair-count telephone cable with aluminum-plastic sheath and multiple twisted pairs | Building voice telephone cabling, conduit or aerial installation
CAT6-UTP | Category 6 unshielded twisted pair cable, 250 MHz bandwidth, 4 twisted pairs | Gigabit LAN integrated cabling
SYWV-75 | Foam coaxial cable with 75Ω impedance and low attenuation | Cable TV, analog surveillance
