The twisted and shielded cables` effect and their choice method:
First: the twisted pair, RVSP also called RVVSP RVVPS twisted cables structure: insulated PVC, PVC sheath and twisted cable, they are suitable for common data transmission.
The transmission distance is close, and its insulated voltage is only dozens of MΩ and its price is the lowest of the twisted pair. The twisted RVSP is suitable in the equipment of power, daily electric appliance, instrument, telecommunication device, lighting lines and fixed installation of automatic device, soft line is used in connection and installation, electric lines applies to the strong Interference situation, the company can manufacture special cables according to different environment, the products are antiflaming(ZR), strong antiflaming(GZR) temperature proof(90℃.105℃.200℃.250℃) , fire proof(NH), twisted type(YJ).
Application environment of the twisted pair:
1.Working temperature: the common type not over 70℃, 105 type not over 105℃.
2.minimum environment temperature: fixed laying is -40℃, non-fixed laying is -15℃.
3.The rated voltage is U0/U 450/750V.
4.The minimum bend radius of non-armor cable is not less than six times of cable`s OD, the minimum bend radius of the armor cables shall not less than 12 times of the cable`s OD.
The combination type of the twisted pair is: R-soft structure cable, V-PVC, S-twisted type, P-copper wire twisted
RVSP also called RVVSP RVVPS and its specification is as follows: rated voltage is 300/500V 1-60 core, 0.08-2.5MM2
Technical parameter is the PVC is not allowed to work under 70℃, the laying temperature of cables shall not below 0℃, the cables which OD is less than 25mm is allowed to be bended. The radius of PVC shall not less than 4 times of cable`s OD, the cables which OD is more than 25mm is allowed to be bended and its radius shall not less than six times of the cable`s OD.
The second type is RYVPS structure, the insulted PVC cables, PVC sheath, twisted shield cables are applied to the common transmission, the transmission distance of the cables is relatively far, and its insulted voltage is superior than RVSP which can reach to 3,000 MΩ or even thousands of MΩ.
