Abstract
The utility model discloses cross-linked polyethylene insulated flame-retardant power cable for mine. The power cable is composed of insulated power wire cores, a flame-retardant filling rope, a metal shielding layer, a steel tape armoring layer and a cross-linked polyethylene outer sheath. Each insulated power wire core is formed by extruding a cross-linked polyethylene insulation layer and a glass fiber wrapping layer in sequence from outside to inside on three tinned copper wire stranded conductors, and a monitoring wire core is arranged in the middle of the three tinned copper wire stranded conductors. The four insulated power wire cores are stranded into a cable core. A mica tape fire-resistant filling layer is arranged in the center of the cable core. A drainage wire is concentrically arranged in the mica tape fire-resistant filling layer. The cross-linked polyethylene outer sheath, the steel tape armoring layer, the metal shielding layer and the flame-retardant filling rope are extruded outside the cable core sequentially from outside to inside. The cross-linked polyethylene insulated flame-retardant power cable for mine of the utility model is reasonable in structure design, has the characteristics of being tensile, fire-resistant and flame-retardant and is suitable to be used in mines. The arrangement of the monitoring wire core is beneficial to daily detection of the cable and ensures the using safety of the cable.
Description
Technical field
The utility model relates to cable, relates in particular to crosslinked polyetylene insulated mining flame-retardant power cable.
Background technology
The power cable using on ships is had relatively high expectations, ageing resistace to power cable, anti-wear performance have strict requirement, and traditional power cable is difficult to meet the instructions for use on ships on ageing resistace and anti-wear performance, therefore need 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 on disembark warship is had relatively high expectations, especially fire prevention, water-fast, shielding properties all must be good.
Utility model content
According to above-mentioned situation, the utility model object is to provide crosslinked polyetylene insulated mining flame-retardant power cable.
Scheme of the present utility model is as follows: crosslinked polyetylene insulated mining flame-retardant power cable, it is made up of insulated power core, fire-retardant gasket for packing, 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 and forms with crosslinked polyetylene insulated layer, glass fibre lapping layer successively, is provided with a monitoring core in the middle of three tinned copper wire stranded conductors; Four thoroughly do away with edge power core twisted synthesizing 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 fire-retardant gasket for packing from outside to inside successively.
The beneficial effects of the utility model: the utility model reasonable in design, there is tension, fire-resistant, fire-retardant feature, be adapted at using in mine, monitoring core be provided with the routine testing benefiting cable, ensure to use safety.
