Abstract
The utility model discloses a mine mobile rubber jacked flexible cable with a rated voltage of 3.6/6kv and below. The mine mobile rubber jacked flexible cable comprises four conductors, wherein the four conductors are arranged in square, a rubber insulation layer and a semiconduction shield layer are sequentially covered outside each conductor from the inside to the outside, a semiconduction filler is filled in a gap among the four conductors, rubber restrictive coatings are extruded outside the four conductors, the section of the semiconduction filler is shaped as a quadrangle, four edges of the quadrangle are hollow inwards and are arc-shaped, holes are arranged in the centre location of the semiconduction filler, a hollow filling tube with a triangular section is arranged in each hole, an elastic body with a circular section is respectively arranged on three gaps between the filling tubes and the holes, and a plurality of elastic bodies with circular sections are arranged on the rubber restrictive coating. The elastic bodies are arranged on the rubber restrictive coating and the semiconduction filler, the flexibility and the tensile property of the cable are increased, the triangular hollow filling tube is increased in stability, and meanwhile the weight of the cable is reduced.
Description
Technical field
The utility model relates generally to field of cables, relates in particular to a kind of rated voltage 3.6/6kV 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 3.6/6kV and following mining mobile rubber sleeve flexible cable to be provided.
The utility model is realized through following technical scheme:
Rated voltage 3.6/6kV 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 the rubber insulation layer; 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 described semiconductive filler is a quadrangle, and tetragonal four limits cave inward curved; Have a hole on the center of semiconductive filler; Being provided with a cross section in the hole is leg-of-mutton hollow filling pipe, and three gaps of filling between the Guan Yukong are respectively equipped with the elastomer of a cross section for circle, and described rubber restrictive coating is provided with many cross sections and is circular elastomer.
