Arcwall contacts with the outer wall of conductor, the radius sidewall of the first insulation strip and the radius sidewall seamless link of the second insulation strip.
First insulation strip 2 and the second insulation strip 3 are set to different colors, and this insulated wire cores comprising different colours claims
For combined color insulated wire cores, conventional has greenish-yellow combined color insulated wire cores, greenish-yellow combined color insulated wire cores grounded circuit,
Having more application in protection circuit, the insulated wire cores that the present embodiment provides is as combined color insulated wire cores, due to its structure
Feature, high to manufacturing technique requirent, compare existing combined color insulated wire cores, the insulated wire cores that the present embodiment provides is to insulating barrier
Extrusion equipment, head technology and operation level requirement are higher, and the two-layer co-extrusion production line needing extrusion capacity bigger just can complete, with
Time also need to design improvement cross-head and diverter.The insulated wire cores technical merit that the present embodiment provides is high, is difficult to be copied,
Solve existing combined color insulated wire cores easily copied, the uneven problem of quality, improve safety.
The present embodiment application is respectively set to green for greenish-yellow combined color insulated wire cores that is first insulation strip 2 and the second insulation strip 3
When normal complexion yellow or yellow and green, green-yellow ratio should also conform to country's cable and wire standard, it may be assumed that to each segment length 15mm
Double-color insulating wire core, each of which color should at least cover the 30% of insulated wire cores surface, and no more than 70%, and another
A kind of color then covers the remainder of insulated wire cores.In the present embodiment, the cross-sectional area of the first insulation strip 2 accounts for insulation
The 30%-70% of layer cross-sectional area.
