Abstract
A fireproof power cable with a high volume used in rail transit comprises a cable core and an outer sheath. A plurality of leads are arranged in the cable core. The each lead is formed by cladding a ceramic silicone rubber insulation layer out of a conductor. Flame retardant glass fiber ropes are arranged between the leads in the cable core. A flame retardant glass fiber band layer is arranged between the cable core and the outer sheath or the flame retardant glass fiber band layer, a silicone rubber inside liner and a steel tape armor layer are successively arranged between the cable core and the outer sheath. The power cable of the invention has good fireproof performance which can satisfy a fireproof requirement of the power cable used in the rail transit. Once a fire is generated on a usage place, during a heating process, the ceramic silicone rubber insulation layer is converted into a ceramic tubular fireproof layer. The higher the temperature is, the better the crusting performance is. The cable can work normally for more than 90 minutes at a temperature of 1200-1500 DEG C. Therefore, precious time can be gained for rescuing equipment and personnel, and losses can be reduced to a lowest degree. In addition, a working temperature of the power cable can reach 180 DEG C which is higher than the working temperature of the common cable. Under the condition of safe usage, the power cable has a larger transmission capacity than the common cable with a same specification.
Description
Technical field
The present invention relates to a kind of power cable, especially a kind of track traffic high power capacity fireproof power cable.
Background technology
It is to strengthen fire resistance that power cable is used in existing track traffic, and the insulating barrier of the lead in its cable core adopts that the multi layer cloud master tape is wrapped to be constituted flame retardant coating and extruded insulation material and process on conductor more.In process of production, often be prone to cause mica tape overlapping the slot place defective to occur, and, burn back mica tape embrittlement, come off easily, cause fire-resistant weak effect, thereby be difficult to ensure the safe handling of power cable under fire condition, bring potential safety hazard to track traffic.
Summary of the invention
In order to overcome the deficiency of existing track traffic, the purpose of this invention is to provide a kind of track traffic high power capacity fireproof power cable with power cable.
A kind of track traffic high power capacity fireproof power cable provided by the invention; Comprise cable core and oversheath; Have several leads in the cable core; Every lead coats the potteryization silicone rubber insulation layer outward by conductor and constitutes; Also be provided with the combustion-proof glass fiber rope between the lead in cable core, between cable core and oversheath, be provided with the fire-retardant glass fiber belt layer.
In order to increase intensity of the present invention, can also between fire-retardant glass fiber belt layer and oversheath, be provided with silicon rubber inner covering and steel-tape armouring layer successively.
In the present invention; The material of making oversheath adopts the low smoke, zero halogen protective cover material, is made up of ethylene-vinyl acetate copolymer 30-35%, ethene improved-acetate ethylene copolymer 8-10%, silicon cave master batch 2%, vinyl bis-stearamides 0.5%, magnesium hydroxide 55-58%, carbon black powder 2%; Making the material of potteryization silicone rubber insulation layer is made up of methyl vinyl silicone rubber 55-60%, white carbon 30-35%, silicone oil 5-8% and an amount of porcelain powder.
The invention has the beneficial effects as follows: the cable fire resistance is good, can satisfy the fire-resistant requirement of track traffic with power cable.In case field of employment breaking out of fire; The pottery silicone rubber insulation layer of lead is heated and changes the flame retardant coating of ceramic tubular into; Temperature is high more; The crust performance is good more; Cable can be in operate as normal under 1200～1500 ℃ the high temperature more than 90 minutes; For equipment is speedily carried out rescue work, the personnel escape wins the quality time, loss is dropped to minimum level.And working temperature of the present invention can reach 180 ℃, is higher than common cable, and the common cable of comparable same specification improves transmission capacity under the prerequisite of safe handling.
