Abstract
The utility model discloses a control cable for an intrinsically-safe type anti-explosion circuit. The control cable is characterized in that a conductor is of a structure with a single tinned copper wire or a structure twisted with multiple tinned copper wires, an insulation wire core is formed by extruding and coating an anti-flaming irradiation cross-linked polyolefin insulation layer on the conductor, a cable core is formed by using multiple insulation wire cores and anti-flaming glass fiber wires as filling materials and adopting a layered twisting mode, the outer layer of the cable core is sequentially provided with a wrapping tape layer, a copper tape shielding layer, an inside liner layer, an armor layer and an outer protection sleeve layer from the inside to the outside, and multiple tinned copper wire drainage wires are arranged between the wrapping tape layer and the copper tape shielding layer. The control cable disclosed by the utility model is anti-flaming, anti-static, oil-proof and anti-lightning stroke, and has good electrical performance and mechanical performance.
Description
Technical field
The utility model relates to a kind of electrical equipment control cable, relates in particular to a kind of inbeing safe explosion prevention circuit and uses control cable, belongs to technical field of electric wires and cables.
Background technology
Industrialized fast development and automaticity improve constantly, and the intellectuality of electrical equipment control appliance will become such industry development.Traditional instrument, instrument and measure and control device will develop towards high-performance, high accuracy, long-life, high stable, direction such as highly sensitive and highly reliable.Increasingly mature along with electron controls technology improved electrical equipment, machinery and instrument automation controlling level.
Because fields such as oil, colliery, chemical industry have certain particularity; The environment of electric equipment operation is abominable; Security requirement is high; Just its supporting cable is had higher requirement accordingly, the stability, fail safe, the anti-interference and anti-wet goods performance that particularly connect the signal cable of deathtrap have proposed requirements at the higher level.Existing control cable can not satisfy related request.
Summary of the invention
The utility model is for avoiding above-mentioned existing in prior technology weak point, providing a kind of intrinsic safety type intrinsically safe circuit to use control cable, in the hope of having high flame retardant, antistatic, oil resistant, anti-thunderbolt and superior electrical performance and mechanical performance.
The utility model technical solution problem adopts following technical scheme:
The utility model intrinsic safety type intrinsically safe circuit is held a little with the structure of control cable: conductor is single or is set to many tinned copper wire lay configuration, on conductor, extrudes fire-retardant cross-linking radiation polyolefin insulation layer and constitutes insulated wire cores; By many insulated core and with the flame-proof glass fibre silk is that inserts adopts layer strand mode to constitute cable conductor; Skin at said cable conductor sets gradually belting layer, copper strips screen, inner covering, armour and external sheath layer from inside to outside; Between said belting layer and screen, many tinned copper wire drainage threads are set.
The utility model intrinsic safety type intrinsically safe circuit also is with the design feature of control cable:
Said belting layer is fire-retardant two-sided semi-conductive adhesive strap.
Said armour adopt the magnetic seizing wire to twine or the magnetic galvanized steel strip double-deck the gap is wrapped forms.
Said external sheath layer is to be that material extrudes and forms with the fire retardant semi-conductive polyolefin plastics.
Compared with present technology, the utility model beneficial effect is embodied in:
1, the utility model insulating barrier adopts fire-retardant cross-linking radiation polyolefine material to extrude, superior electrical property, and flame retardant effect is better;
2, the utility model belting layer is fire-retardant two-sided semi-conductive adhesive strap, and adopts the wrapped screen of metal tape, can discharge induction static a large amount of on the insulated wire cores, reduces cable surrounding environment generation electromagnetic interference or surrounding environment are produced interference to cable;
3, the armour in the utility model adopts the magnetic metal structure, can play the effect of carrying or lateral pressure resistant power on the one hand, can play the effect of anti-magnetic disturbance on the other hand;
4, the external sheath layer in the utility model is that material extrudes and forms with the fire retardant semi-conductive plastic, and fire-retardant, antistatic, anti-thunderbolt, oil resistant corrosion are safe, are fit to move under the special adverse circumstances such as oil, chemical industry.
Description of drawings
Fig. 1 is that the utility model four-core intrinsic safety type intrinsically safe circuit is used the control cable structure chart;
Label among the figure: 1 conductor, 2 insulated wire cores, 3 inserts, 4 belting layers, 5 drainage threads, 6 screens, 7 inner coverings, 8 armours, 9 external sheath layers.
Embodiment
In the practical implementation, belting layer 4 is fire-retardant two-sided semi-conductive adhesive strap; Armour 8 adopt the magnetic seizing wires to twine or the magnetic galvanized steel strip double-deck the gap is wrapped forms; External sheath layer 9 is to be that material extrudes and forms with the fire retardant semi-conductive polyolefin plastics.
