Abstract
The utility model discloses a waterproof and fireproof cable comprising multiple conductors. The cross sections of the conductors are compacted in shapes of sectors or circles. The conductor is successively wrapped in a waterproof layer formed by wrapping a waterproof tape, and an insulating layer in order to form an insulating wire core. The insulating wire cores are mutually twisted in order to form a cable core. The cable core is wrapped in an inner isolating composite layer which is successively wrapped in an inner sheath layer and an outer composite isolating layer. The outer composite isolating layer and the inner isolating composite layer are both formed by wrapping waterproof tapes, aluminum-plastic composite tapes, and glass fiber tapes from inside to outside. The outer composite isolating layer is wrapped in an armored layer formed by wrapping a tin-coated steel tape, and an outer sheath layer. The waterproof and fireproof cable has novel structural design of the inner and the outer isolating composite layers, the waterproof layer, and the filling layer so as to achieve characteristics of good mechanical performance and electrical performance and easy processing. In addition, the cable has excellent waterproof performance and the fireproof performance and the service life of the cable is prolonged.
Description
Technical field:
The utility model relates to cable, relates in particular to a kind of fire-resisting cable that blocks water.
Background technology:
Because China some areas (areas to the south, the Changjiang river) are rainy throughout the year, the block-water performance requirement of laying installation cable is more and more paid attention to.The cable long-play is in rainy environment, and moisture is immersed in conductor and the insulation that mainly influences cable in the cable.Make the conductor oxidation, increase conductor resistance, increase the energy loss of transmission line; Insulation suction back produces the water tree, makes the cable that is in operation take place to puncture and damage.
On the other hand, add up according to fire department, in the Urban Fires, be because the cable fire that causes of electrical equipment fault fire cable traffic overload spreads causes more than 2/3, simultaneously, in many fire in the past, what cause personal property danger and " secondary harm " often mainly is the toxic gas that discharges behind the cable fire, and the fireproofing of cable technology more and more causes people's attention.
The utility model content:
In order to remedy the prior art problem, the purpose of this utility model provides a kind of fire-resisting cable that blocks water, reasonable in design, and block-water performance, fire resistance, mechanical performance are good.
The technical solution of the utility model is as follows:
Fire-resisting cable blocks water, comprise several conductors, it is characterized in that: described several conductors by stipulate among several GB/T3956 the 2nd the class copper wire is stranded forms, stranded lay ratio is 14 ~ 20 times, several cross-sectional area of conductor press into fan-shaped or circular, several conductors are provided with the wrapped formation water blocking layer of waterstop outward respectively successively, insulating barrier constitutes insulated wire cores, the mutual stranded bunchy of insulated wire cores constitutes cable core, in being provided with, cable core isolates composite bed outward, the interior composite bed of isolating is provided with inner restrictive coating outward successively, outer compound insulation layer, outer compound insulation layer, the interior composite bed of isolating all adopts waterstop from inside to outside successively, aluminium-plastic tape, glass fibre belt carries out wrapped formation, and outer compound insulation layer is coated with the armour of the wrapped formation of zinc-plated steel band, external sheath layer.
The described fire-resisting cable that blocks water is characterized in that: the gap in described between compound insulation layer and the cable core is filled with waterproofing rope and is constituted packed layer.
The described fire-resisting cable that blocks water is characterized in that: described insulating layer material adopts polyethylene.
The described fire-resisting cable that blocks water is characterized in that: described inner restrictive coating is made of the wrapped internal layer of aluminium-plastic tape, polyethylene extrusion moulding skin.
The described fire-resisting cable that blocks water is characterized in that: described armour adopts galvanized steel strip to form.
The described fire-resisting cable that blocks water is characterized in that: described external sheath layer material adopts refractory silicon rubber.
The utility model has the advantages that:
The utility model structural design novelty, characteristics such as the inside and outside structural designs such as composite bed, water blocking layer, packed layer of isolating make cable not only have favorable mechanical performance and electric property, and are easy to process, block water, fire resistance is good, prolonged the useful life of cable.
