Abstract
The invention discloses a crosslinked polyethylene insulated mining flame-retardant power cable which is composed of insulated power line cores, a flame-retardant filling rope, a metal shielding layer, a steel band armoring layer and a crosslinked polyethylene oversheath. Each insulated power line core is obtained through extruding a crosslinked polyethylene insulating layer and a glass fiber winding layer on three tin-coated copper wire intertwisted conductors successively from outside to inside. The central part of the three tin-coated copper intertwisted conductors is provided with a monitoring core. Four insulated power line cores are intertwisted for obtaining a cable core. The middle part of the cable core is provided with a mica tape fireproof filling layer. A drainage wire is coaxially arranged in the mica tape fireproof filling layer. The crosslinked polyethylene oversheath, the steel band armoring layer, the metal shielding layer and the flame-retardant filling rope are successively extruded on the cable core from outside to inside. The crosslinked polyethylene insulated mining flame-retardant power cable has advantages of reasonable structure design, high tension resistance, high fireproof performance and high flame-retardant performance. The crosslinked polyethylene insulated mining flame-retardant power cable is suitable for use in a mine. The monitoring core facilitates daily detection for the cable, and furthermore ensures high safety in use.
Description
Technical field
The present invention relates to cable, particularly relate to crosslinked polyetylene insulated mining flame-retardant power cable.
Background technology
The power cable that ships uses requires higher, to the ageing resistace of power cable, anti-wear performance, there is strict requirement, and traditional power cable is difficult to the instructions for use that meets on ships in ageing resistace and anti-wear performance, therefore needs a kind of novel material to meet anti-aging, the wear-resisting requirement of power cable.Natural butadiene-styrene rubber has good anti-wear performance, hot strength, tearing strength and ageing-resistant performance, and resistance to water and air-tightness are also better, but the combination property that the cable needs on disembark warship is higher, especially prevent fires, water-fast, shielding properties all must be excellent.
Summary of the invention
Accordingly, the object of the invention is to provide crosslinked polyetylene insulated mining flame-retardant power cable.
The solution of the present invention is as follows: crosslinked polyetylene insulated mining flame-retardant power cable, it is made up of insulated power core, flame resistant filler rope, metal screen layer, steel-tape armouring layer and crosslinked polyethylene oversheath, described insulated power core ecto-entad is extruded on three tinned copper wire stranded conductors with crosslinked polyetylene insulated layer, glass fibre lapping layer successively and forms, and is provided with a monitoring core in the middle of three tinned copper wire stranded conductors; Four thoroughly do away with edge power wire core is twisted into cable core; Described cable core center is provided with the fire-resistant packed layer of mica tape, and a drainage thread is arranged in the fire-resistant packed layer of master tape with one heart; Described cable core is extruded with crosslinked polyethylene oversheath, steel-tape armouring layer, metal screen layer and flame resistant filler rope from outside to inside successively.
Beneficial effect of the present invention: reasonable in design of the present invention, has tension, fire-resistant, fire-retardant feature, is adapted at using in mine, and that monitors core is provided with the routine testing benefited cable, ensures use safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention,
Wherein: 1, insulated power core; 2, crosslinked polyetylene insulated layer; 3, glass fibre lapping layer; 4, tinned copper wire stranded conductor; 5, flame resistant filler rope; 6, metal screen layer; 7, steel-tape armouring layer; 8, crosslinked polyethylene oversheath; 9, drainage thread; 10, the fire-resistant packed layer of mica tape; 11, core is monitored.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described;
As shown in Figure 1, crosslinked polyetylene insulated mining flame-retardant power cable, it is made up of insulated power core 1, flame resistant filler rope 5, metal screen layer 6, steel-tape armouring layer 7 and crosslinked polyethylene oversheath 8, described insulated power core 1 ecto-entad is extruded on three tinned copper wire stranded conductors 4 with crosslinked polyetylene insulated layer 2, glass fibre lapping layer 3 successively and forms, and is provided with a monitoring core 11 in the middle of three tinned copper wire stranded conductors 4; Four thoroughly do away with edge power wire core 1 is twisted into cable core; Described cable core center is provided with the fire-resistant packed layer of mica tape 10, drainage thread 9 and is arranged in the fire-resistant packed layer 10 of master tape with one heart; Described cable core is extruded with crosslinked polyethylene oversheath 8, steel-tape armouring layer 7, metal screen layer 6 and flame resistant filler rope 5 from outside to inside successively.
Although give detailed description and explanation to the specific embodiment of the present invention above; but what should indicate is; we can carry out various equivalence according to conception of the present invention to above-mentioned execution mode and change and amendment; its function produced do not exceed that specification contains yet spiritual time, all should within protection scope of the present invention.
