Huier Cable's Qeb 3 Plenum Cable yog nruab rau hauv lub tsev rov qab cua plenums rau ob qho tib si yooj yim thiab zoo nkauj. Qeb 3 Riser Cable yog qhov zoo tagnrho rau kev teeb tsa hauv ntsug riser thiab kev siv kab rov tav dav dav.

Ib Qeb 3 cable (Cat 3 cable) yog ib hom unshielded twisted khub (UTP) cable uas yog siv rau lub suab thiab cov ntaub ntawv kev sib txuas lus nyob rau hauv lub computer thiab telecommunication tes hauj lwm. Nws yog Ethernet tooj liab cable txhais los ntawm Electronics Industry Alliance (EIA) thiab Telecommunication Industry Association (TIA).

Muaj nyob rau hauv ntau lub tsho xim thiab cov khub suav, General Cable tus nqi -zoo qeb 3 cables tau raws li cov neeg siv khoom xav tau rau txhua daim ntawv thov.

SHIELDED CABLE (STP) vs UNSHIELDED CABLE (UTP)

Cat 3 cables feem ntau yog siv nrog unshielded twisted khub (UTP). Txawm li cas los xij, ib puag ncig uas muaj lub cev muaj zog loj, lub tshuab hluav taws xob, thiab qee yam ntawm siab -voltage teeb pom kev zoo yog qhov tseem ceeb ntawm Electromagnetic and Radio Frequency Interference (EMI/RFI). Hauv cov ntawv thov no, shielded twisted khub (STP) cable yuav pab tiv thaiv cov ntaub ntawv teeb liab thaum txuas kom raug. Hu rau peb los tham txog koj daim ntawv thov!

Txawm hais tias koj tab tom ua kev teeb tsa tshiab lossis hloov kho koj cov txheej txheem uas twb muaj lawm, Warehouse Cables muaj Cat 3 bulk cable koj xav tau, ntawm tus nqi pheej yig!

Cov txiaj ntsig thiab cov yam ntxwv

Plenum

Siv rau hauv cov kav dej thiab qhov chaw ua haujlwm raws li Tshooj 800 ntawm National Electrical Code (NEC)

Cov kab no yog UL (USA) & cUL (Canada) teev rau daim ntawv thov no los ntawm kev dhau NFPA 262 (FT6 lossis yav dhau los UL 910 Steiner Tunnel) xeem

Tsis yog -plenum

Rau siv raws li ib tug ntsug khiav nyob rau hauv ib tug ncej thiab rau lub hom phiaj kev sib txuas lus siv raws li tsab xov xwm 800 ntawm NET

Cov kab no yog ETL (USA) & cETL (Canada) teev rau daim ntawv thov no los ntawm kev xeem dhau UL 1666 Riser Cable Flammability Test

Kuj tseem dhau qhov CSA FT4 Vertical Flame Test - Cables hauv Cable Trough los ntawm kab lus 4.11.4 ntawm CSA C22.2 Tsis yog. 0.3

Tsim nyob rau xyoo 1990, Cat 3 cable yog ib qho ntawm cov ntaub ntawv xov xwm nrov tshaj plaws txog xyoo 2000. Nws yog siv hauv 10Base-T thiab token nplhaib tes hauj lwm uas nws muaj peev xwm xa cov ntaub ntawv ntawm qhov ceev ntawm 10 Mbps. Thaum siv hauv 100BaseT tes hauj lwm, Cat 3 cable tuaj yeem nqa cov ntaub ntawv ntawm qhov nrawm dua li nws lub hauv paus ceev.

Cat 3 cable muab lub suab sib txuas lus zoo vim nws muab 16 MHz bandwidth, uas yog ntau tshaj li txaus rau kev hu xov tooj. Nws kuj tseem nrov nyob rau hauv ib puag ncig network qhov twg electromagnetic cuam tshuam yog qhov kev txhawj xeeb tsawg.
