How to buy instrument cable voltage level 2024-07-16 17:23:13 internet

This product for instrument is suitable for signal transmission and control lines in instruments, instruments and other electrical equipment.The rated voltage of the cable below 500V, the long -term working temperature of the cable core should not exceed 70 ° C.The cable allows the bending radius to not be less than 6 times that of the outer diameter of the cable, and the laying temperature should not be less than 0 ° C.[
Instrument cable selection
The thermocouple compensation cable and the compensation wire are a pair of or more pairs of wires or cables with the same thermocouple value of the thermocouple with the matching thermocouple in the same temperature (including normal temperature).Measuring devices to compensate the errors generated by the temperature changes at the connection between them to the thermocouple, the compensation wire and the compensation cable are divided into extension type and compensation type.Basic models: KX-HS-FP1V105P1, KX-HS-FP1V105, KX-HS-FV105, KX-HS-FFP1, KX-HS-FP1FP1, KX-HS-FP1F, KX-HS-FF, KX-GS-VVVP, KX-GS-VPVP, KX-GS-VPV, KX-GS-VV
Instrument cable standard
(1) The laying of the electrical line of the instrument shall comply with the current national standards "Electrical Device Installation Engineering Cable Roupes Construction and Acceptance Specifications" GB50168-92 and "Construction and Acceptance Specifications for Wiring Engineering and Acceptance of Electrical Device Installation Projects 1KV and Wiring Projects" GB50258-96The relevant provisions.(2) Before the cable wire is laid, the appearance inspection and guide should be performed, and the insulation resistance is measured with a DC 500V meter table.When designing documents have special regulations, it shall comply with its regulations.
Instrument cable voltage level
450 refers to the fire floor voltage. 750 refers to the phase voltage. That is to say, when this line uses a single -phase electricity, it can bear up to 450 volts..Their models are BV, BV-105.BV, the BV-105 for Polyvinyl chloride insulation wires is the heat-resistant polyvinyl chloride insulation wire 400V below the single-core copper wire section with 0.75㎜2, 1.05mm2,1.5mm2,2.5mm2,4mm2,6mm2, load current, 20C °, 20C °
Illustration cable layout specification
Cable selection specifications: (1) According to the specifications, models and types of design drawings, the required cables are selected.(2) Confirm the cable model according to the identification on the cable disk, and select the cable disk according to the sequence of the laying cable and number.(3) The selection of cable specifications must be consistent with the design drawings.
