Description

Flame-retardant oil-gas pipeline high-speed bus cable armored by spiral copper pipe

Technical Field

The utility model relates to the technical field of oil and gas pipeline cables, in particular to a flame-retardant oil and gas pipeline high-speed bus cable armored by a spiral-line copper pipe.

Background

The oil gas pipeline high speed bus cable is mainly suitable for the connection of battlefield pipeline control systems such as crude oil, product oil, natural gas and the like, field instruments and equipment for transmitting digital signals, and can realize fault diagnosis and the connection of intelligent induction system equipment in an intelligent pipeline. The existing bus cable structure comprises a solid bare copper conductor, an external insulating layer, a twisted pair of two cores, an aluminum-plastic composite film shield, a copper mesh woven shield and an outer sheath.

The existing bus cable has poor compression resistance in the use process, and because the structure of the cable determines that the force can directly penetrate through the outer sheath, the steel belt (if any), the copper mesh and the aluminum-plastic composite belt to shield and directly act on the insulated wire core when the cable is stressed, the position of the two core wires is changed, and the loss of the cable is increased easily, so that the transmission safety is influenced. In addition, when the cable is fixed, because the surface of cable is comparatively smooth, the spacing snap ring that plays the fixed action to the cable takes place to become flexible easily, influences the installation effect. Moreover, the woven shield of the longitudinally-wrapped aluminum-plastic composite film and the copper wire cannot prevent the corrosion of water and moisture, and once water enters or is affected by damp, immeasurable loss can be caused.

The drawings are for illustrative purposes only and are not to be construed as limiting the patent; for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1, the embodiment discloses a flame-retardant oil-gas pipeline high-speed bus cable armored by a spiral copper pipe, which comprises a cable core, an armor layer and a flame-retardant layer, wherein the cable core, the armor layer and the flame-retardant layer are sequentially arranged from inside to outside;

the cable core comprises a pair-twisted group, the pair-twisted group is formed by twisting two insulated wire cores at a certain pitch, and each insulated wire core comprises a conductor 1 and an insulating layer 2; the insulating layer 2 is arranged outside the conductor 1, and the conductor 1 is a solid bare copper wire.

As shown in fig. 1, the armor layer is longitudinally wrapped outside the cable core, the armor layer is a spiral corrugated copper pipe 3, the spiral corrugated copper pipe 3 is installed through armor, and due to the fact that the compression resistance of the spiral corrugated copper pipe 3 is good, and meanwhile, due to the arrangement of the spiral corrugated copper pipe 3, force cannot be directly applied to the cable core, the transmission safety of the cable and the overall compression resistance of the cable are enhanced; when the cable is fixed, the limiting snap ring can be tightly fixed on the spiral corrugated copper pipe 3, so that looseness is not easy to occur when the cable is installed, the overall stability of the cable is improved, the radial moisture resistance of the device is enhanced, and the overall safety performance of the cable is improved.

As shown in fig. 1, the flame-retardant layer is extruded outside the armor layer, the flame-retardant layer is a flame-retardant outer sheath material 4, and the flame-retardant performance of the cable can be improved through the arrangement of the flame-retardant layer.
