According to the definition of IEC6 1 158 standard, the field bus refers to the digital, serial and multipoint communication data bus between the field equipment installed in the manufacturing process area and the automatic control equipment in the control room. There are many kinds of communication media connecting field devices, and each communication media has great influence on data transmission rate, communication distance, reliability of data transmission, cost and difficulty of installation and maintenance. The communication media of fieldbus system mainly include bus cable, microwave and infrared ray, among which bus cable is the most commonly used and stable.
This product is suitable for the connecting line between process automation control and measuring equipment in the factory's grass-roots field environment, so as to build an open and decentralized digital field bus communication system. Suitable for cable tray (bracket) and pipeline installation in indoor, outdoor, humid or dry environment.
Second, the production process:
Unarmored:
Three-layer * * extruded physical foamed skin-foamed skin FPE insulation (high-density foaming), double-layer shielding+tinned TC conductor, flame-retardant orange ultraviolet-proof outer sheath, stranded A-type bus cable;
Armor type:
Three-layer * * extruded physical foam skin-foam skin FPE insulation (high-density foam), double-layer shield+tinned TC conductor, double-layer sheath (flame retardant and ultraviolet protection), galvanized steel wire winding or braided armor, stranded A-type bus cable.
Third, the electrical indicators
1, working capacitance (1kHZ):
Core wire and core wire ≤60PF/M, core wire and shielding layer ≤110pf/m.
2. Unbalanced capacitor for shielding (1kHZ):
Shielding unbalanced capacitance ≤2000PF/KM.
3. Characteristic impedance (3 1.25kHZ)
Characteristic impedance 100 20ω
4. Attenuation (20℃, 39 kHz)
The maximum attenuation value of cable signal during transmission is 3.0dB/km.
5. Transmission distance
The maximum transmission distance of physically foamed type A bus cable is1900m.
Fourth, product advantages.
The overall design of type A FF field bus cable has the characteristics of flame retardancy, low attenuation, long transmission distance, superior anti-interference performance, flexibility and ease of use, which fully meets the requirements of IEC6 1 158 standard for field bus cable design.
