1. CCTVYees duab videoCtuaj yeem: SYV75-3 video cable feem ntau xa tawm tsis pub dhau 200 metres, 75-5 xa mus rau hauv 400 metres, 75-7 tuaj yeem xa mus rau 800 meters; qhov zoo tshaj ntawmCCTVCoaxial cable, RG59, RG6, yuav tsum tau them sai sai rau. Ob lub RG11 thiab RG11 xav tau 100% tus tub ntxhais tooj liab thiab 95% tooj liab npiv thaiv cov txheej txheem. Qhov siab tshaj plaws ntawm kev sib txuas ntawm lub voj voos sib txuas tsis tau tshaj 15 ohms. Thaum qhov kev ncua deb tshaj li 500 metres, nws yog qhov tsim nyog los xav txog kev siv cov kab hluav taws xob xa khoom.

 

2. Lub thawv fais fab: Cov nplaim hluav taws xob-txuas ntxiv yuav tsum tau xaiv, thiab cov tuab yuav tsum tau siv ntau npaum li ua tau kom txo tau cov xeeb ceem ntawm cov khoom siv fais fab.

 

3. Cov kab tswj: feem ntau siv kev tiv thaiv 2 * 1.0 cable, RVVP2 * 1.0.

 

  1. Threading yeeb nkab: PVC yeeb nkab lossis PVC lub cev tuaj yeem siv dav dav, thiab galvanized steel yeeb nkab yuav tsum tau siv rau cov txheej txheem av qeeg lossis tawg-pov thawj.
