Embodiment 1

[0046] The first embodiment is an insulated core wire, refer to figure 1As shown, the insulated core wire includes a conductor 1, and the outer peripheral side of the conductor 1 is sequentially covered with an inner insulating layer 2 and an outer insulating layer 3 along its radial direction; the inner insulating layer 2 is an HDPE insulating layer, and the outer insulating layer 3 is FEP insulation.

[0047] Among them, HDPE is a copolymer of tetrafluoroethylene and hexafluoropropylene.

[0048] Wherein, the conductor 1 is a single crystal copper conductor, and the conductor 1 is single or multiple, that is, one or more conductors 1 are arranged in a single inner insulating layer 2 .

[0049] The insulated core wire in this embodiment includes a conductor 1, and the outer peripheral side of the conductor 1 is coated with an HDPE insulating layer and a FEP insulating layer in turn; since the FEP insulating layer is arranged on the outside of the HDPE insulating layer, and t...

Embodiment 2

[0067] The second embodiment is a high flame retardant data cable, refer to image 3 As shown, it includes the sheath layer 4 and the insulated core wire in Embodiment 1, and the sheath layer 4 covers the outer peripheral side of the insulated core wire.

[0068] The high flame-retardant data cable in this embodiment can produce the beneficial effect of the insulated core wire in Embodiment 1, and will not be repeated here.

[0069] In this embodiment, there are multiple insulated core wires, and each insulated core wire is paired and twisted respectively. Two pairs of twisted wires 5 are formed, and there are multiple groups of twisted wires 5; The outer peripheral side of line 5.

[0070] Wherein, the twisted wires 5 are arranged in 4 groups.

[0071] In this embodiment, a tear line 6 is provided inside the sheath layer 4 , and the extension direction of the tear line 6 is the same as that of the conductor 1 .

[0072] Among them, adding the tear wire 6 in the data cable ...

Abstract

The invention provides an insulated core wire, a high-fire-retardant data cable and the processing craft thereof, particularly relates to the technical field of the cables and cords. The insulated core wire comprises a conductor wherein the periphery of the conductor covers an inner insulation layer and an outer insulation layer in turn along the radial direction. The inner insulation layer is the HDPE insulation layer and the outer insulation layer is the FEP insulation layer, which solves the technical problem of the low of the insulated core wire temperature grade and flame retardant grade in the prior art and is capable of greatly improving the temperature grade and flame retardant grade of the cables. And the data cable owns the technical effects of higher security transfer property and fireproof performance.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to an insulating core wire, a high flame-retardant data cable and a manufacturing process for the two. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. Insulated covering layer, the cable has the characteristics of internal electrification and external insulation. Commonly used wires and cables are divided into the following categories: bare wires, insulated wires, heat-resistant wires, shielded wires, power cables, control cables, data cables, and radio frequency cables. Among them, data cables are mainly used in network wiring in residential areas and commercial buildings. [0003] Since the data cable is the most used in the building's integrated wiring and is directly distributed in every...
