Abstract
The utility model discloses a mine fire-resistant rubber-sheathed flexible cable, which comprises a cable core which is arranged in the center of the cable. A glass fiber band is lapped outside the cable core, then a ceramic silicon rubber inner sheath is extruded, a glass fiber band is lapped and finally an outer sheath is extruded at the outermost layer. The cable core of the cable can be all kinds of structures in mine cables. When the cable is a monitoring mine rubber-sheathed flexible cable, two layers of glass fiber bands are lapped outside the inner sheath and a monitoring core is arranged between the two layers of glass fiber bands. By adopting the structure which is formed by the glass fiber band, the silicon rubber inner sheath and the glass fiber band, the glass fiber bands can prevent burning, silicon rubber forms a hard ceramic protection layer during burning and can take effects of isolating flame and preventing fire, heat and oxygen can be isolated and are prevented from being transferred, and the integrity of insulating materials can be guaranteed under the situation of burning.
Description
Technical field
The utility model relates to a kind of cable, specifically is a kind of mining fire-resistant rubber sleeve flexible cable.
Background technology
In recent years, coal mining accident takes place frequently and makes safety of coal mines affect the popular feeling, and the colliery also shows especially out with the importance of cable security.Particularly how under fire condition, ensureing the unimpeded of electric power and communication line within a certain period of time, try to gain time precious to one to greatest extent, reduce personnel's the injures and deaths and the loss of lives and properties, is the problems that people constantly explore.Therefore the research and development of carrying out fire-resistant mining cable are very important.Fire-resistant mining cable can keep the normal operation of certain hour under the flame combustion situation, can keep the integrality of circuit.The acid gas amount of smoke that produces during the burning of fire resistant flame retardant mining cable is few, and the fire resistant flame retardant performance improves greatly, particularly when burning, is accompanied by water spray and machinery and hits under the situation of vibrations, and mining cable still can keep the circuit entire run.
At present, the fire-resisting cable that magnesium oxide fire-proof insulation cable that fireproof electric wire and cable both domestic and external adopts mostly and mica tape twine, magnesium oxide fire-proof insulation cable need special equipment, cost height, are not suitable for long distance power supply; The fire-resisting cable mica tape mica that mica tape twines comes off easily.The potteryization fire-resistant silicon rubber is employed gradually, the material of main part of potteryization fire-resistant silicon rubber is heat cure (HTV) silicon rubber, the fundamental characteristics that possesses silicon rubber at normal temperatures is as nontoxic, tasteless, high-low temperature resistant, anti-ozone aging, weather-proof aging, electrical insulation capability and good processing properties etc.The electric wire that the adding auxiliary agent is made in the silicon rubber, the characteristic that cable still possesses silicon rubber under normal conditions; under 500 ℃ of high temperature even the flame ablation more than 700 ℃; silicon rubber forms hard pottery protective layer; thereby play isolated flame, fireproof effect, under fire condition, guaranteed the unimpeded of electric power, communication.But wait insulating material to compare with second third insulation, the insulation property of silicon rubber are relatively poor relatively, therefore generally can not therefore limit its use as the insulation of medium and high voltage cable.
The utility model content
Technical problem to be solved in the utility model provides the good mining midium voltage cable that blocks water of a kind of water resistance.
Mining fire-resistant rubber sleeve flexible cable described in the utility model comprises the cable core that is positioned at cable center, and wrapped glass fiber band outside cable core extrudes potteryization silicon rubber inner sheath then, wrapped again glass fiber band, and outermost layer extrudes oversheath again.
Cable core of the present utility model can be for each class formation in the mining cable, and when being the monitoring type rubber sheathed flexible cable for mine, wrapped glass fiber band is two-layer in the inner sheath outside, and the supervision core is set in the middle of layer glass silk fiber band.
The utility model is the improvement on the prior art basis, and it extrudes potteryization silicon rubber inner sheath then by wrapped glass fiber band outside cable core, at the wrapped one deck glass fiber band in inner sheath outside, extrudes oversheath at last more again.The excellent relatively material of ethylene-propylene rubber or other insulation property is still adopted in insulation, has guaranteed insulation property.Adopt the structure of glass fiber band+silicon rubber inner sheath+glass fiber band; wherein the glass fiber band can stop burning; silicon rubber forms hard pottery protective layer during burning; play isolated flame, fireproof effect; and can heat insulation oxygen barrier; avoid the transmission of heat and oxygen, under combustion case, can guarantee the integrality of insulating material.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of mining fire-resistant rubber sleeve flexible cable described in the utility model comprises the cable core 1 that is positioned at cable center, wrapped glass fiber band 2 outside cable core 1, extrude potteryization silicon rubber inner sheath 3 then, wrapped again glass fiber band 4, outermost layer extrudes oversheath 5 again.
The utility model provides a kind of thinking and execution mode of mining fire-resistant rubber sleeve flexible cable; concrete application approach is a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvement, these improvement also should be considered as protection range of the present utility model.
