Abstract
The utility model discloses a steel pipe sheath electric cable for an oil-submerged pump. The steel pipe sheath electric cable comprises three conductors with sectional area from 10mm2 to 25mm2, insulation layers are formed in an extrusion molding mode outside the three conductors respectively so as to form insulation wire cores, the insulation wire cores are parallelly arranged, connection bands are arranged between the insulation layers of the insulation wire cores to be integrally connected to form cable cores, sheath layers are formed outside the cable cores in the extrusion molding mode, and fully-closed steel pipes are sleeved outside the sheath layers. The steel pipe sheath electric cable for the oil-submerged pump has the advantages that the structural design is reasonable, the connection bands are arranged between the insulation layers of the electric cable, the whole structure performance of the electric cable is improved, the fully-closed steel pipes are arranged outside the sheath layers so that the oil resistance, humidity resistance and structure intensity of the electric cable are improved, the steel pipe sheath electric cable can be used in harsh environment, and the power transmission safety is guaranteed.
Description
Technical field:
The utility model relates to the power cable field, relates in particular to a kind of oil-immersed pump steel tube dirt-proof boot 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 tube dirt-proof boot 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 tube dirt-proof boot cable comprises three conductors, it is characterized in that: the sectional area of described three conductors is 10～25mm
2, three conductors outward respectively extrusion moulding have insulating barrier to consist of insulated wire cores, insulated wire cores is placed side by side, is 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 set with the totally enclosed type steel pipe outward.
Described oil-immersed pump steel tube dirt-proof boot cable is characterized in that: described insulating barrier and related employing fluoropolymer extrusion moulding.
Advantage of the present utility model:
The utility model reasonable in design, be provided with related 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 tube dirt-proof boot cable comprises that the sectional area of 1, three conductor 1 of three conductors is 10～25mm
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, is provided with the related 3 formation cable cores that link into an integrated entity between the insulating barrier 2 of insulated wire cores, and the outer extrusion moulding of cable core has restrictive coating 4, the restrictive coating 4 outer totally enclosed type steel pipes 5 that are set with, totally enclosed type is compared steel band lock armo formula electric cable of submersible pump, owing to adopting 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 fluoropolymer extrusion moulding.
