●線芯導(dǎo)體為4N無(wú)氧銅束絞而成,抗氧化,訊號(hào)通導(dǎo)率高,衰減小。
●此類電纜適用于優(yōu)質(zhì)視頻信號(hào)的傳輸,有效屏蔽雜波。特性阻抗穩(wěn)定,衰減小,導(dǎo)線與屏蔽層的電容恒定,滿足視頻信號(hào)的優(yōu)質(zhì)傳輸。
●SYV 采用低損耗發(fā)泡處理,線芯導(dǎo)體采用單根或多根4N銅絲,屏蔽層采用鋁泊或銅網(wǎng)編織,屏蔽密度高更適合固定安裝。(低溫沖擊脆化溫度可達(dá)-30℃)
●The cables have stranded 4Noxygenfree copperas thecore conductor,which resistsoxidation,ensureshigh transmissionrate and lowttenuation.
●The cables areto be usedfor the transmission of vide signals and have such eatures as strongshielding capabilty,stable characterist impedance,low attenuation and stable capacitance between wire and shield,all of which guarantee the effective transmission of video signals.
SYV cable,having gone through alowlossfoaming proces,has asingle 4Ncoper wire asits core conductorand aluminum foilplusbraided copperasits shield
so as to have a high shield density and be more suitable for fixed installation.(brittle temperature:-30℃
