Abstract
The utility model discloses a mining mobile rubber jacketed flexible cable used at 380/660-volt rated voltage and below. The cable comprises four conductors, wherein the four conductors are arranged in a square mode; a wrapping tape layer, a rubber insulating layer and a semiconducting shielding layer wrap each conductor from inside to outside; a semiconducting filler is filled in gaps among the four conductors; a rubber sheath layer is extruded outside the four conductors; the cross section of the semiconducting filler is quadrilateral; four edges of the quadrilateral inwards dent and are arc-shaped; four corners and a central position of the semiconducting filler are provided with a hole respectively; and a tension resistant steel wire is arranged in each hole. The cable has a simple structure, is convenient to manufacture and high in fire resistance and resists high temperature; and tension resistant performance is improved under the condition that the weight of the cable is not increased.
Description
Technical field
The utility model relates generally to field of cables, relates in particular to a kind of rated voltage 380/660V and following mining mobile rubber sleeve flexible cable.
Background technology
Mining cable is the abbreviation of colliery with cable, and mining cable is flame retardant cable, all should pass through the national mining product safety sign of peace mark center and issue mining product safety sign certificate.
Wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety satisfies rate and domestic market occupation rate all above 90%.Worldwide, the Chinese electric wire gross output value has surpassed the U.S., becomes first in the world electric wire producing country.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.China's economic growth continuously and healthily; For cable products provides the huge market space, the temptation that Chinese market is strong makes the world all focus on Chinese market to sight; Reforming and opening up to the outside world short decades, the formed huge production capacity of Chinese cable manufacturing industry lets the world regard with special esteem.Along with the continuous expansion of industry sizes such as China Power industry, data communication industry, urban track traffic industry, coal mining, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire already also has huge development potentiality.
Coal-mining development grows stronger day by day, and people's awareness of safety constantly strengthens, and the performance and the environmental requirement of the cable supporting with it also improved constantly.Therefore, be badly in need of a kind of high temperature resistant, good flame resistance, safe mining power set with moving the cable that lays.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of rated voltage 380/660V and following mining mobile rubber sleeve flexible cable to be provided.
The utility model is realized through following technical scheme:
Rated voltage 380/660V and following mining mobile rubber sleeve flexible cable; Include four conductors, described four conductors are square arrangement, it is characterized in that: the described every conductor outside is enclosed with rubber insulation layer, semiconductive shielding layer from inside to outside successively; Gap between described four conductors is filled with the semiconductive filler; Four conductors are extruded with the rubber restrictive coating outward, and the cross sectional shape of semiconductive packed layer is a quadrangle, and tetragonal four limits cave inward curved; Have a hole on four angles of semiconductive filler and the center, be provided with the tension steel wire in the hole.
The thickness of described rubber insulation layer is 1.4-2.4mm.
The thickness of the thinnest part of described rubber restrictive coating is for being not less than 3.5mm.
The utility model has the advantages that:
The utility model is simple in structure, manufacturing is convenient, its good flame resistance, high temperature resistant, and under the situation of not extra increase cable weight, improved pull resistance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
