Abstract
The utility model belongs to the cable field, and specifically relates to a special cable for a deepwater submersible pump. The special cable for the deepwater submersible pump comprises a cable core, a waterproof layer and a sheath layer successively from inside to outside, wherein the cable core is composed of multi-strip conductor beams and multi-strip steel wire bearings, and the conductor beams and the steel wire bearings are all provided with insulating layers; and the conductor beams are prepared by tinning annealed copper wires, the insulating layers and the sheath layer are prepared by ethylene-propylene diene monomer rubber, and the steel wire bearings are prepared by soft steel strands. The special cable is good in waterproof performance and strong in bearing capability, and compared with a traditional product, mechanical property and absorption property in a deepwater environment are largely improved.
Description
Technical field
The utility model belongs to field of cables, is specifically related to a kind of deep submersible pump private cable.
Background technology
Along with increasing of city and agricultural water, underground water well water intaking is more and more darker, and deep submersible pump is used more and more.Because common submersible pump cable cannot meet the requirement of big-length, high capacity, cause deep submersible pump in routine duties, the phenomenon such as often occur power-off, blow.
Summary of the invention
For the problems referred to above, the utility model provides a kind of deep submersible pump private cable, and this cable block-water performance is good, weight capacity is strong, than absorbent properties under traditional product mechanical performance and deepwater environment, is greatly improved.
The utility model is achieved through the following technical solutions:
A deep submersible pump private cable, comprises cable core, water blocking layer and restrictive coating from inside to outside, and described cable core is reassembled into by many strip conductors bundle and many bearing steel wires, and described conductor bundle and steel wire load-bearing are equipped with insulating barrier outward; Described conductor bundle is tin annealed copper wire, and described insulating barrier and restrictive coating are ethylene propylene diene rubber, and described steel wire load-bearing is mild steel twisted wire.
According to above-mentioned deep submersible pump private cable, by filament diameter, the strand of the galvanized steel tow below 0.2mm forms described mild steel twisted wire.
According to above-mentioned deep submersible pump private cable, described cable core is reassembled into by two strip conductor bundles and two bearing steel wires.
positive beneficial effect of the present utility model:
1) the utility model conductor adopts the zinc-plated flexible cord of the 6th class, in the pliability of cable, greatly improves, and while preventing that cable distortion is excessive, conductor is broken; Adopt tin annealed copper wire, prevent that conductor is for a long time under moist environment and be oxidized, and improved the fastness of terminal weld.
2) the utility model insulating barrier and restrictive coating adopt water-fast and compression resistance type ethylene propylene diene rubber, than water absorbing properties under traditional product mechanical performance and deepwater environment, are greatly improved.
3) the utility model bearing steel wires is reformed as the load-carrying members of cable, after core stranding, adds, and is not affecting under the pliability prerequisite of cable, has improved the weight capacity of cable, to adapt to deepwater work environment.
4) the outer wrapped one deck waterstop of the utility model core stranding, when cable is under moisture conditions, waterstop expands, thereby has improved the block-water performance of cable.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model embodiment 1.
In figure, 1 is conductor bundle, and 2 is steel wire load-bearing, and 3 is insulating barrier, and 4 is water blocking layer, and 5 is restrictive coating.
