Multicore enamelled wire conductor charge bearing detecting cable adopts around-packing technology to tie up technique multiple conducting wires is formed to a cable core so that fill armour steel wire, single core enamelled wire conductor charge bearing detecting cable does not adopt this technique, and the difference of the multicore enamelled wire conductor charge bearing detecting cable structure causing thus and single core enamelled wire conductor charge bearing detecting cable structure can be found out by comparison diagram 3 and Fig. 4.
Enamelled wire conductor charge bearing detecting cable, the selection principle of enamelled wire is:
The temperature index of enamelled wire is: the insulating material temperature resistant grade that requires the temperature resistant grade of enamelled wire to select with cable is identical.
The wire diameter of enamelled wire requires: in enamelled wire, the sectional area of conductor will equate with corresponding stranded conductor sectional area.Such selection principle, the external diameter of enamelled wire conductor is less than corresponding stranded conductor, and this is also the place by the advantage of enamelled wire conductor.
The material of enamelled wire requires: generally select oxygen-free copper, also do not get rid of and select other material.
Further improvement of the present invention part is: conductor 4 is single core copper conductor.
Adopt the charge bearing detecting cable of single core copper conductor as conductor 4, single core copper conductor also can be applied to the charge bearing detecting cable of plurality of specifications as conductor, specification can be 1 core, 3 cores, 5 cores, 7 cores or the charge bearing detecting cable that needs any core number of design according to design.
Adopt the charge bearing detecting cable of single core copper conductor as conductor 4, it can be multicore charge bearing detecting cable, structure is and replaces respectively the stranded conductor in traditional multicore charge bearing detecting cable with single core copper conductor, and multicore charge bearing detecting cable adopts and wrappedly ties up that multiple conducting wires is formed a cable core by technique so that dress armour steel wire.
