Detailed description

Izstrādāts precīzām RF pielietojumiem, koaksīālais kabelis RG223/U ir 50 omu risinājums ar darbības frekvenci līdz 6 GHz. Kabelis atbilst standarta MIL M17/194-00001 (iepriekšējais apzīmējums M17/84-RG223) prasībām, kas apliecina tā uzticamību sarežģītos apstākļos. Kabelī ir sudraba pārklājuma vara centrālais vads ar diametru 0,88 mm, polietilēna (PE) dielektriķis ar diametru 2,95 mm un dubultā sudraba pārklājuma vara ekrāna vija (96% pie 3,6 mm, 94% pie 4,2 mm), kas nodrošina 85 dB ekrāna efektivitāti frekvenču diapazonā no 0,0001 GHz līdz 1 GHz.

Elektriskās un mehāniskās īpašības

Ar 50 Ω ±1Ω impedanci un 101 pF kapacitāti koaksīālais kabelis RG223/U nodrošina stabilu un ātru signāla pārraidi ar izplatīšanās ātrumu 66% un 5 ns/m aizkavējumu. Izolācijas pretestība ir 100 000 000 MΩ*m, bet iekšējā vada pretestība — 27,7 Ω/km. Kabelis paredzēts darbībai ar maksimālo spriegumu 2,5 kV un pārbaudes spriegumu 5 kV (50 Hz/1 min), kas to padara piemērotu dažādiem jūras un rūpnieciskiem pielietojumiem.

Mehāniskā ziņā kabelis sver aptuveni 55 g/m, statiskais lieces rādiuss ir ≥ 30 mm, bet atkārtotās lieces rādiuss — 54 mm, nodrošinot elastību instalācijas laikā un saglabājot struktūru. 5,4 mm diametrā (RAL 9005 — melna) PVC II apvalks (ar zema migrācijas līmeni) nodrošina aizsardzību pret vides ietekmi. Koaksīālais kabelis RG223/U darbojas temperatūras diapazonā no -25 °C līdz 85 °C un var tikt instalēts no -20 °C līdz 60 °C. Tas satur halogēnus, ko ir jāņem vērā, izvēloties ugunsdrošības standartus.

Salīdzinot ar kabeliem, piemēram, RG58, RG223/U izceļas ar dubulto ekrānu, kas nodrošina labāku elektromagnētisko traucējumu imunitāti un augstāku darbības frekvenci līdz 6 GHz. Tas padara to par piemērotāko izvēli sistēmām, kuras prasa augstu signāla integritāti, piemēram, radariem, augstas klases VHF/UHF sakaru sistēmām vai augstas ātrdarbības datu tīkliem uz laivas. Tas ir savietojams ar U9 kabeļu grupas savienotājiem.

« Technical analysis of RG223/U coaxial cable for marine applications »

The RG223/U coaxial cable is a proven standard for RF connections requiring superior signal integrity in marine environments. Its compliance with MIL M17/194-00001 is not trivial; it ensures rigorous manufacturing and performance, essential for critical onboard applications. Unlike a standard RG58, the RG223/U features double silver-plated copper shielding, a key characteristic for attenuating electromagnetic interference (EMI) common in a vessel's environment, particularly near engines, generators, or other electronic equipment. This design provides a shielding effectiveness of 85 dB up to 1 GHz, which is crucial for maintaining signal quality at high frequencies up to 6 GHz.

This cable is particularly suited to radar installations, AIS Class A/B systems, high-performance marine VHF/UHF radios, or demanding data networks where insertion loss and impedance stability (50 Ω) are critical. It is recommended for use when cable lengths are significant or the route passes through areas with strong electromagnetic interference. While installation requires skills in crimping or soldering U9-type coaxial connectors—similar to other coaxial cables—the quality of materials (silver-plated conductors and shields, low-migration PVC II jacket) ensures enhanced durability against moisture, UV, and temperature variations (-25 °C to 85 °C in operation). Note that its halogen composition may be a consideration in environments subject to strict fire safety standards.
