1. OPGW Fiber Composite Av Cable
Cov khoom OPGW Lawv sib koom ua ke cov haujlwm ntawm cov hlau av thiab kev sib txuas lus kho qhov muag, thiab feem ntau yog siv rau cov kab sib txuas lus ntawm cov kab ke xa hluav taws xob siab dua tshiab ntawm 35 KV thiab siab dua, thiab kuj tseem siv tau los hloov cov xov hlau av uas twb muaj lawm ntawm cov kab ke xa hluav taws xob siab dua qub, txhim kho cov kab sib txuas lus kho qhov muag thiab ua cov hluav taws xob luv luv thiab muab kev tiv thaiv xob laim.
Cov yam ntxwv ntawm cov khoom OPGW: stainless hlau raj optical fiber unit thiab txhuas-clad tooj liab hlau, braided txhuas alloy hlau thiab cabling; stainless hlau raj optical fiber unit nyob rau hauv nruab nrab lossis sab hauv txheej ntawm braided txheej.
2. MASS Cov xov hlau kho qhov muag uas txhawb nqa tus kheej
MASS (Metal Aerial Self-Supporting) yog ib txoj hlua zoo ib yam li OPGW (Open Point Ground Wire) nrog ib txheej stranded core. Yog tsis muaj kev teev tseg lwm yam, cov hlua hlau stranded feem ntau yog ua los ntawm cov hlau galvanized, ua rau muaj cov qauv yooj yim thiab tus nqi qis dua. MASS yog ib yam khoom uas txuas qhov sib txawv ntawm OPGW thiab ADSS (Advanced Optical Fiber Support). Thaum siv ua ib txoj hlua optical uas txhawb nqa tus kheej, qhov tseem ceeb tshaj plaws yog lub zog thiab sagging, nrog rau qhov kev nyab xeeb ntawm cov neeg hlau hauv av / xov hlau thiab hauv av. Tsis zoo li OPGW, nws tsis tas yuav xav txog qhov luv luv tam sim no thiab lub peev xwm kub, OPPC, rwb thaiv tsev, lub peev xwm nqa tam sim no, thiab impedance, thiab ADSS, nws tsis tas yuav xav txog lub zog teb ntawm qhov chaw teeb tsa. Lub luag haujlwm ntawm cov hlua hlau sab nraud tsuas yog los pab thiab tiv thaiv cov fiber optical. Yog tias muaj lub zog tawg zoo sib xws, txawm hais tias MASS hnyav dua ADSS, nws txoj kab uas hla sab nraud yog kwv yees li 1/4 me dua li ntawm ADSS lub raj tub ntxhais thiab kwv yees li 1/3 me dua li ntawm ADSS txheej. Rau ib txoj kab uas zoo sib xws, lub zog tawg thiab kev ntxhov siab tso cai ntawm ADSS qis dua li ntawm MASS.
