Abstract
The utility model discloses a sea-water-resistant control cable. The cable comprises three conductors, and an ethylene propylene rubber insulating layer is molded outside each conductor through plastic extrusion, so that three insulating cores are formed. The insulating cores, distributed in a shape like a Chinese character pin, are placed in a parallel and longitudinal manner to form a cable core. A taped layer taped by a water-resisting belt is arranged outside the cable core, the thickness of the raped layer is not less than 1.2mm, and the raped wrapping rate of the taped layer is not less than 40%. A polyvinyl chloride inner sheath layer, a shielding layer braided by a tin-coated copper wire, and a polyvinyl chloride out sheath layer are successively disposed outside the taped layer. An anticorrosion layer is disposed outside the polyvinyl chloride out sheath layer and is not less than 0.85mm in thickness. The cable of the utility model has a simple structure. The taped layer is taped by the water-resisting belt, and the inner sheath layer and the outer sheath layer are cooperated with the anticorrosion layer, so that environment adaptability of the cable is greatly improved, power transmission and communication transmission are guaranteed to be stable and the service life of the cable is prolonged.
Description
Technical field:
The utility model relates to control cable, relates in particular to a kind of sea water resistance type control cable.
Background technology:
At present the control cable of using is manufactured the technological process of this type of soft control cable according to GB/T9330-2008: conductor bundle is twisted insulating exruded stranding-extrude sheath, and roughly four technologies are crossed and become to finish.To existing soft control cable bending radius on the market bigger (be not less than the outside diameter of cable 6 times), do not satisfy the installation needs of small space sometimes, bending radius is too small can the damage cable, influences the normal use of product.
In addition, the block-water performance weakness of cable, long-term work causes cable transmission electric power and communication to can not get ensureing in the environment of seawater.
The utility model content:
In order to solve the problems of the technologies described above, the purpose of this utility model provides a kind of sea water resistance type control cable, and reasonable in design has improved the adaptive capacity of cable to environment, increases the service life.
The technical solution of the utility model is as follows:
Sea water resistance type control cable, comprise three conductors, it is characterized in that: described three conductors outward respectively extrusion moulding have ethylene propylene rubber insulated layer to constitute insulated wire cores, the parallel in a triangle vertical formation cable core of putting of insulated wire cores, cable core is provided with the lapping layer of the wrapped formation of waterstop outward, lapping layer thickness is not less than 1.2mm, the wrapped rate of putting up of lapping layer is not less than 40%, lapping layer is provided with the neoprene inner restrictive coating outward successively, the screen that the tinned copper wire braiding constitutes, the polyvinyl chloride external sheath layer, described polyvinyl chloride external sheath layer is provided with corrosion-inhibiting coating outward, and the thickness of corrosion-inhibiting coating is not less than 0.85mm.
Described sea water resistance type control cable is characterized in that: described three conductors all adopt the multiply copper free wire to constitute with the bundle strand, and bundle strand back conductor outer wall scribbles tin coating, and the resistivity of copper free wire is less than 0.017242 Ω .mm
2/ m (20 ℃).
The utility model has the advantages that:
The utility model structural design is simple, and it is wrapped that lapping layer adopts waterstop to carry out, and inside and outside simultaneously two restrictive coatings cooperate corrosion-inhibiting coating, have greatly improved the adaptive capacity of cable to environment, ensures the stable of electric power, communication transmission, has prolonged useful life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
