RS485 twisted pair shielded communication cable

RS485 twisted pair shielded communication cableRS485 twisted pair shielded communication cable

485Communication cables can be routed together with high-voltage power lines. In actual construction, due to the fact that the wiring is carried out through pipelines, sometimes the construction party, for the convenience of the drawings, directly485The signal line and power line are tied together, and due to the strong electromagnetic signal of strong electricity, it interferes with weak electricity, resulting in485Signal instability leads to unstable communication. workCommunication networks such as industrial control networks and power automation.

IIRS485Main technical requirements for cables
1Conductor: Multiple strands of tinned copper wire twisted and conductor used. The surface of the conductor is free of defects such as oil stains and dust. The direct current resistance of the conductor must comply with the standard regulations.
2Insulation: using ordinaryPVCThe insulation material should be extruded, and the insulation surface should be smooth and round without natural shrinkage. The diameter of the insulation wire core should be strictly produced according to this process, and the color of the insulation wire core should be separated according to customer needs.
3Twist the insulated wire core into a cable, with a round outer diameter and uniform pitch. The outer surface of the cable core should be wrapped tightly with polyester tape.
4Add7/0.15Tin plated wire is used as a drainage ground wire, and then an aluminum-plastic composite tape is added as an intermediate package.
5Weaving: Tin plated braided shielding is used, and the shielding density is generally60%or80%The weaving layer requires smoothness, no burrs, no missing weaving, no oil stains or other obvious quality defects.
6Sheath: Made of ordinary purple colorPVCThe sheath material is extruded, and the surface of the sheath is smooth and round.
7Printing: Cover printing model and specifications（RS458 1*2*24AWG）;The printing is clear and durable, and the printing is white. (If there are special needs, they shall be provided by the purchaser)
