Abstract
The utility model discloses a flexible water-proof cabtyre cable for a submersible motor. The cable comprises a conductor and insulating cable cores formed by insulating layers extruded on the outer circumference of the conductor, wherein the insulating layers are formed by extruding ethylene propylene diene rubber, water-proof packing gaskets are filled in the clearances among the insulating cable core strands, water-proof belt layers are winded outside the water-proof packing gaskets, and an outer sheath is extruded on the outmost layer of the cable. The cable has the advantages of good water-proof performance, superior electric property, long service life and excellent security, thereby being a brand new product in the cable manufacture field.
Description
Technical field:
The utility model relates to a kind of cable, specifically a kind of submersible motor waterproof rubber sleeve flexible cable.
Background technology:
At present, submersible motor adopts general rubber sleeve flexible cable in the GB5013 standard with cable more, often occurs sheath water inlet and conductor water inlet phenomenon in the use, causes the conductor oxidation and resistance rising and insulation resistance decline, thereby influences the useful life of cable.The ac capacitor suction increment of insulation is big; The permission minimum bending radius of cable is 6 times the outside diameter of cable when laying.This series products can not satisfy the waterproof requirement of submersible motor with cable, and this type of Cable Bending Radius is big, and can not satisfy submersible motor needs roving requirement with cable.
The utility model content:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of good electric property, submersible motor waterproof rubber sleeve flexible cable that water resistance is superior.
The utility model technical solution problem adopts following technical scheme:
Submersible motor waterproof rubber sleeve flexible cable, comprise conductor and be extruded in the formed insulated wire cores of insulating barrier of conductor periphery, in the gap of described insulated wire cores stranding, be filled with the gasket for packing that blocks water, the wrapped belting layer that blocks water outside the described gasket for packing that blocks water, the outermost layer of cable is extruded with oversheath.
Insulating barrier is extruded by ethylene-propylene diene copolymer and is formed.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
Be filled with the gasket for packing that blocks water of water-swellable in the insulated wire cores stranding gap of cable, the packed layer that blocks water is surrounded with the belting layer that blocks water of same water-swellable outward, though cable have small amount of moisture to enter also can't contact insulation layer and conductor, guarantee that cable can normally use.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Number in the figure: 1 conductor, 2 insulating barriers, 3 gasket for packings that block water, 4 belting layers that block water, 5 oversheaths.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment,
Non-limiting examples is as described below:
Embodiment: shown in Figure 1, conductor 1 adopts many copper conductor lay configuration, outside conductor, extrude the insulating barrier 2 formation insulated wire cores that ethylene-propylene diene copolymer mixes then, in insulated wire cores stranding gap, be filled with water-swellable and have the gasket for packing 3 that blocks water of block-water performance, be surrounded with the belting layer 4 that blocks water in cable stranding process, the outermost layer of cable is extruded with the oversheath 5 that waterproof chlorosulfonated polyethylene and lead oxide and magnesium oxide compound are made.In cable stranding process (during stranding control lay ratio less than 8 times), the wrapped stranding control lay ratio that blocks water during belting layer 4 is less than 8 times.
After testing, the utility model cable has following performance:
1, the insulation temperature resistant grade can reach 90 ℃, improves current-carrying capacity of cable and heat resistanceheat resistant breakdown capability;
The permission minimum bending radius of cable is 4 times the outside diameter of cable when 2, laying;
3, the ac capacitor of cable insulation suction increment is less, cable insulation is 800-1000Hz in frequency, and voltage is under the alternating voltage of 3kV, between the 14th day end and the 1st day end, between the 14th day end and the 7th day end, its ac capacitor suction is rised in value respectively less than 15% and 5%.
5, the cable outermost layer adopts the higher oversheath of compactness by waterproof chlorosulfonated polyethylene and lead oxide and the making of magnesium oxide compound, finished cable at 5 times on the cylinder of the outside diameter of cable, crooked ten times, can be 3040Pa by hydraulic pressure smoothly, time is 2 hours the transverse sealing hydraulic test, and the cable exposed portions serve is water-tight.It is good that this cable has water resistance, excellent electrical properties, the excellent various performances of long service life and fail safe.
Claims (2)
1, submersible motor waterproof rubber sleeve flexible cable, comprise conductor (1) and be extruded in the formed insulated wire cores of insulating barrier (2) of conductor periphery, it is characterized in that, in the gap of described insulated wire cores stranding, be filled with the gasket for packing that blocks water (3), the wrapped belting layer that blocks water (4) outside the described gasket for packing that blocks water (3), the outermost layer of cable is extruded with oversheath (5).
2, submersible motor according to claim 1 waterproof rubber sleeve flexible cable is characterized in that, insulating barrier (2) is extruded by ethylene-propylene diene copolymer and forms.
