Abstract
The utility model discloses a steel-sheathed cable for an oil-immersed pump. The steel-sheathed cable comprises three conductors whose sectional areas are between 8 to 30 square centimeters. The three conductors are respectively wrapped by an insulation layer which is formed through extrusion molding to form insulation wire cores. The insulation wire cores are placed side by side. Connecting belts are arranged among the insulation layers of the insulation wire cores, and the insulation wire cores are connected to be a whole body to form a cable core. The cable core is wrapped by a sheath layer which is formed through extrusion molding. The sheath layer is wound by a spiral steel wire which is wrapped by a corrosion resistant layer. The sheath layer is sleeved by a full closed steel tube. The steel-sheathed cable is reasonable in structural design, the connecting belts are arranged among the insulations of the cable, the sheath layer is wound by the spiral steel wire, the overall structural performance of the cable is raised, the design of the full closed steel tube is used outside the sheath layer, the oil resistant and moisture-proof performance and structural strength of the cable are raised, the cable can be used in a bad environment, and the security of power transmission is ensured.
Description
Technical field:
The utility model relates to the power cable field, relates in particular to a kind of oil-immersed pump steel bushing cable.
Background technology:
Oil-immersed pump full name oil-submersible centrifugal pump is centrifugal multistage pump multiple centrifugal pump, mainly by the multistage centrifugal impeller, lead shell, pump shaft, pump case and upper lower contact etc. and form.In people's production process, not only needing also needs the auxiliary element of pump is optimized to paying attention in the pump body structure design, and the jump lead of oil-immersed pump needs to pay attention to equally.
Original cable is relatively poor in combination property, and namely the performances such as the structural strength of cable, insulation property, fire prevention oil resistant are weak, causes electric power transfer to can not get safely ensureing, has caused a certain amount of property loss.
The utility model content:
The purpose of this utility model provides a kind of oil-immersed pump steel bushing cable, be applicable to being connected between ac rated voltage 3.6/6KV and following oil-immersed pump unit and the oil-immersed pump motor, solved cable because the problem of structural strength, insulation property, the relatively poor electric power transfer obstacle that brings of fire prevention oil resistance.
Technical scheme of the present utility model is as follows:
Oil-immersed pump steel bushing cable comprises three conductors, it is characterized in that: the sectional area of described three conductors is 8～30mm
2Three conductors outward respectively extrusion moulding have insulating barrier to consist of insulated wire cores, insulated wire cores is placed side by side, be provided with the related formation cable core that links into an integrated entity between the insulating barrier of insulated wire cores, the outer extrusion moulding of cable core has restrictive coating, restrictive coating is wound with spiral steel wire outward, and steel wire is provided with anti-corrosion layer outward, and restrictive coating is set with the totally enclosed type steel pipe outward.
Described oil-immersed pump steel bushing cable is characterized in that: described insulating barrier and related employing silicon rubber extrusion moulding.
Advantage of the present utility model:
The utility model reasonable in design, be provided with spiral steel wire related, that restrictive coating is outer between the insulating barrier of cable, improved the overall structure performance of cable, restrictive coating adopts the design of totally enclosed type steel pipe to improve oil resistant humidity resistance and the structural strength of cable outward, can adapt to comparatively and use under the rugged environment, ensure electric power transfer safety.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
Referring to Fig. 1:
Oil-immersed pump steel bushing cable comprises that the sectional area of 1, three conductor 1 of three conductors is 8～30mm
2Three conductor 1 outer respectively extrusion moulding have insulating barrier 2 to consist of insulated wire cores, insulated wire cores is placed side by side, be provided with the related 3 formation cable cores that link into an integrated entity between the insulating barrier 2 of insulated wire cores, the outer extrusion moulding of cable core has restrictive coating 4, be wound with spiral steel wire 5 outside the restrictive coating 4, the steel wire 5 outer anti-corrosion layers 6 that are provided with, the restrictive coating 4 outer totally enclosed type steel pipes 7 that are set with, totally enclosed type is compared steel band lock armo formula electric cable of submersible pump, owing to adopt the totally enclosed type sheath, working life is the longest can be extended down to 10 years, and the voltage withstand class of cable also is further improved simultaneously.
Insulating barrier 2 and related 3 adopts the silicon rubber extrusion moulding.
