Yuav ua li cas xaiv CCTVCmuaj peev xwms?

 

 

 

 

 

 

 

1. Yees duab Cmuaj peev xwm: SYV75-3 video cmuaj peev xwm generally transmits within 200 meters, 75-5 transmits within 400 meters, and 75-7 can transmit 800 meters; the quality of CCTVCoaxialCmuaj peev xwm kuj tseem ceeb,RG59U, RG6 Ob tusRG11 and RG11 require 100% copper core and 95% copper braided shielding layer. The maximum resistance of the circuit loop connection cannot exceed 15 ohms. When the distance exceeds 500 meters, it is necessary to consider the use of optical cmuaj peev xwm transmission.

 

2. Lub thawv fais fab: Flame-retardant cmuaj peev xwms should be selected, and thicker ones should be used to reduce the attenuation of the power supply.

 

3. TswjhwmCmuaj peev xwm:  Generally use shielded 2*1.0 cmuaj peev xwm, RVVP2*1.0.

 

  1. Xov Threading yeeb nkab: PVC yeeb nkab lossis PVC pob tw siv tau rau hauv dav dav, thiab galvanized steel yeeb nkab yuav tsum tau siv rau cov txheej txheem av qeeg lossis tawg-pov thawj.
