Abstract

The utility model discloses a sinle silk protection type cable, sheath, metal armor layer in insulation core protective layer, cable core, fire prevention, cable core include many the insulation core that are equipped with the insulation core protective layer, and insulation core constitutes by the conductor and around the insulating layer of package on the conductor, the interior sheath of fire prevention, metal armor layer in cable core outside cladding. The utility model relates to a sinle silk protection type cable can select the core -number of cable according to different demands, and the crowded package of insulation core protective layer prevents that insulation core insulating layer when hank system cable core receives the friction and is damaged on insulation core, and insulating properties is good simultaneously, strong heat resistance, chemically -resistant characteristic.

Description

A kind of core protection type cable

Technical field

The utility model is related to technical field of electric wires and cables, more specifically refers to a kind of core protection type cable.

Background technology

At present, cable with field is more and more extensive, therefore cable is sometimes in the middle of the rugged environment, if electric The not no good safeguard measure of cable itself, when rugged environment is run into, transmittability, the service life of cable can all be subject to shadow Ring, cable can the power-off because of these special circumstances, therefore, it is necessary to do further protection to core, improve cable Physical life, running into special situation cable can normally run.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of core protection type cable.

For achieving the above object, the utility model is employed the following technical solutions：A kind of core protection type cable, including insulation Core protective layer, cable core, fire prevention sheath, metal armor layers, described cable core is provided with the insulated wire cores including a plurality of The insulated wire cores of protective layer, described insulated wire cores are made up of conductor and the wrapped insulating barrier on conductor；Described cable core Outside is coated with described fire prevention sheath, metal armor layers.

Wherein：The thickness of described insulated wire cores protective layer is 2 to 3 times of thickness of insulating layer.

Wherein：Described insulated wire cores protective layer is crosslinked polyethylene material.

Wherein：Described insulated wire cores protective layer is extruded in the insulated wire cores.

Wherein：Described cable core is made up of two, three, four or five insulated wire cores.

The utility model beneficial effect compared with prior art is：A kind of core protection type cable, can be according to difference Demand selects the core number of cable, and insulated wire cores protective layer is extruded in insulated wire cores, prevents insulated wire cores in process cable core Insulating barrier is rubbed and is damaged, while good insulation preformance, heat resistance is strong, chemical-resistant characteristic.

Description of the drawings

Fig. 1 is a kind of structural section schematic diagram of core protection type cable specific embodiment of the utility model；

Reference

The insulated wire cores protective layer of 10 conductor 40

The fire prevention sheath of 20 insulating barrier 50

The metal armor layers of 30 insulated wire cores 60

Specific embodiment

In order to more fully understand technology contents of the present utility model, with reference to specific embodiment to skill of the present utility model Art scheme is further described and illustrates, but is not limited to this.

Specific embodiment as shown in Figure 1, a kind of core protection type cable, including insulated wire cores protective layer 40, cable core, Fire prevention sheath 50, metal armor layers 60, cable core includes a plurality of insulated wire cores 30 for being provided with insulated wire cores protective layer 40, insulation Core 30 is made up of conductor 10 and wrapped insulating barrier 20 on the conductor 10；Cable core outside is coated with fire prevention sheath 50, gold Category armor 60.

Further, the thickness of insulated wire cores protective layer 40 is 2 to 3 times of thickness of insulating layer, improves the strong of insulating barrier Degree.

Further, insulated wire cores protective layer 40 is crosslinked polyethylene material, and the material good insulation preformance, heat resistance is strong, Chemical-resistant characteristic.

Wherein, insulated wire cores protective layer 40 is extruded in insulated wire cores 30.

In the present embodiment, cable core number is four, in other embodiment, cable can may be selected according to different demands Core number is two, three or five.

In sum, a kind of core protection type cable of the utility model, can select the core number of cable according to different demands, Insulated wire cores protective layer is extruded in insulated wire cores, prevents insulated wire cores insulating barrier in process cable core from being rubbed and being damaged Bad, while good insulation preformance, heat resistance is strong, chemical-resistant characteristic.

It is above-mentioned that technology contents of the present utility model are only further illustrated with embodiment, it is easier to understand in order to reader, But do not represent embodiment of the present utility model and be only limitted to this, any technology done according to the utility model extends or recreates, Be defined by claims by protection of the present utility model, protection domain of the present utility model.
