There are salt fog and the high low temperature effect of greasy filth burn into and unfavorable factor such as inflammable on the platform of offshore oil exploitation, having a strong impact on the serviceability of cable, the existing common cable that is made of cable core and outer jacket can not be satisfied the demand, so be badly in need of a kind of supporting with it private cable of exploitation.
The utility model content
The purpose of this utility model is exactly for satisfying the needs in market, a kind of offshore oil platform fire control type corrosion resistant weather armoured cable being provided.
The purpose of this utility model is to realize like this, offshore oil platform fire control type corrosion resistant weather armoured cable, comprise cable core and outer jacket, it is characterized in that the flame-retardant layer that on cable core, sets gradually, water blocking layer, inner sheath and armour, the cable core of described cable core for being twisted into by four insulated wires and packed layer, wrapped high flame retardant glass fibre belt flame-retardant layer on cable core, the wrapped bilayer strap water blocking layer that blocks water on flame-retardant layer, on water blocking layer, extrude low-smoke non-halogen flame-retardant cross-linked polyolefin inner sheath, braiding zinc-coated wire armour extrudes low-smoke non-halogen flame-retardant cross-linked polyolefin outer jacket on the armour on inner sheath.
Described insulated wire is made of conductor and insulating barrier, described conductor is that many zinc-plated oxygen-free copper skein silk systems form, described insulating barrier is by inner insulating layer and external insulation layer, described inner insulating layer is that mica tape is wrapped on conductor, and described external insulation layer is that flame-retardant crosslinking polyethylene evenly is extruded on the inner insulating layer.
Described packed layer is filled in the slit of four insulated wires for the non-hygroscopic gasket for packing.
The strand system lay ratio of described cable core≤8 cable core diameters.
The wrapped Duplication of described high flame retardant glass fibre belt is 30%-50%.
The utility model is rational in infrastructure simple, manufactures easily, and serviceability is good.The transmission performance of cable is stable, has good heat-resistant, resistance to acids and bases, and radioresistance, good insulation preformance, mechanical strength is higher, and fire resistance is good, is specially adapted to the supporting private cable of offshore oil platform power-equipment power circuit.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-conductor, 2-inner insulating layer, 3-external insulation layer, 4-inserts, 5-flame-retardant layer, 6-water blocking layer, 7-inner sheath, 8-armour, 9-outer jacket.
Embodiment
