Amsa da ake gano kable na coaxial a kan ƙananan karamin kula?
A cikin hukuma kana iya tattauna da coaxial cable (Coaxial Cable) a cikin electrical conduit (Electrical Conduit), zai iya duba abubuwa daban-daban, sama da kyakkyawan siffar, nau'in kable, nau'in conduit, da kuma aiki na musamman. A nan ne bayanin mai sarrafa:
1. Kyakkyawan Siffar da Kudin Gida
NEC (National Electrical Code): Idan ana amfani da National Electrical Code (NEC) a Amurka, ba a tabbas ake gina coaxial cables a cikin conduit na biyu da power cables. Ana ambaci a NEC Section 820.133 cewa ba a yi aiki na communication cables (sama da coaxial cables) a cikin conduit na biyu da power cables, ba tare da a yi masu suna daidai ko a yi amfani da shielded cables da suka fi sanya.
IEC da Kyakkyawan Duniya: Ana samun kyakkyawa mafi yawa a kasashen na duniya. Misali, IEC standards (International Electrotechnical Commission) da kyakkyawan siffar na duniya suna nufin cewa communication cables da power cables ya sa a yi amfani da sabon conduit don in bincike kyakkyawa da kalite na signal.
2. Interference na Electromagnetic (EMI)
EMI daga Power Cables: Power cables suna haifar electromagnetic fields wanda suke iya cutar signals a coaxial cables, musamman signals na ma'ana (sama da TV, satellite, ko internet signals). Wannan cutar zai iya haifar signal attenuation, kalite na image, ko errors na data transmission.
Shielding Effectiveness: Idan an yi amfani da coaxial cables na inganci, akwai shielding layers masu kyau wanda suke iya yanayi EMI, amma ba za a iya yanayi duk interference. Saboda haka, don in bincike kalite na signal, ya kamata a yi amfani da coaxial cables da power cables a cikin conduit daban-daban.
3. Space na Physical da Zan'iya na Installation
Limited Conduit Space: Electrical conduits suna da space da yake cikin power cables, kuma ba suka da space da yake cikin coaxial cables. Idan conduit ya samu power cables, idan an yi amfani da coaxial cable zai iya haifar zan'iya na installation da kuma ake bukatar kuwa a kan kyakkyawan siffar.
Bend Radius: Coaxial cables suna da minimum bend radius. Idan conduit ya samu space da yake ko kuma yawancin bends, zai iya haifar structure na cable, wanda yake zai iya haifar performance.
4. Hazards na Kyautar
Fire Hazard: Idan power cable ya jawo failure ko short out, zai iya haifar fire. Idan an yi amfani da coaxial cables a cikin conduit na biyu da power cables, zai iya haifar fire spreading, musamman a cikin environments da aka samu air circulation da yake.
Electric Shock Risk: Idan coaxial cable ya faruwa da power cables ko insulation ya jawo damage, zai iya haifar electric shock, musamman a cikin environments da take da ruwa ko corrosive.
5. Alternative Solutions
Separate Routing: Yawancin tarihi ita ce a yi routing na coaxial cables da power cables a cikin conduits da pathways daban-daban. Wannan zai bincike interference da kuma haifar risks na kyautar.
Metal Conduit or Shielding: Idan an bukata a yi amfani da coaxial da power cables a cikin area na biyu, zai iya amfani da metal conduit ko shielding sleeve don in yanayi EMI. Da kuma a yi amfani da physical distance (misali, at least 15-30 cm) a cikin biyu da kabilu zai iya yanayi interference.
Summary
Idan ana amfani da kyakkyawan siffar da kudin gida, ba a tabbas ake gina coaxial cable a cikin electrical conduit, musamman idan conduit ya samu power cables. Idan an yi haka, zai iya haifar EMI, reduced signal quality, zan'iya na installation, da kuma potential safety risks. Don in bincike reliability da kyautar na system, tarihi ita ce a yi routing na coaxial cables da power cables a cikin conduits da pathways daban-daban. Idan an bukata a yi amfani da biyu da kabilu a cikin area na biyu, zai iya amfani da isolation da shielding measures, da kuma a yi amfani da local regulations.
