Abstract
The invention provides a high pressure resistant reinforced insulation motor leading connection soft cable. The high pressure resistant reinforced insulation motor leading connection soft cable comprises a central fiber rope, multiple conductors and interval filler, wherein the interval filler fills the space between every two adjacent conductors, and the multiple conductors and the interval filler surround the central fiber rope to form a cable core of a finished cable. Each conductor comprises a wire, a composite semi-conductor shielding taped covering and an ethylene propylene rubber insulating layer, wherein the composite semi-conductor shielding taped covering and the ethylene propylene rubber insulating layer wrap the wire in sequence. A fiber rope cross woven mesh layer wraps the cable core of the finished cable, and a chloroprene rubber outer sheath wraps the fiber rope cross woven mesh layer in an extrusion mode. The high pressure resistant reinforced insulation motor leading connection soft cable is soft on the whole, has a small bending radius, meets the special requirement of multi-bending when a motor winding leading connection wire is used, reinforces the insulating property, can bear higher tensile strength, prolongs the service life, reduces the intervals among the conductors and the insulating layers, guarantees an effective and uniform electric field, reduces production working procedures, and improves production efficiency.
Description
Technical field

Background technology
At present, the high-tension electricity power traction in motor train unit connects uses flexible cord cable, is applicable to directly for good and all be connected with motor winding and draws casing or winding is connected with the binding post root on electric machine casing.Cable need bear high voltage and the electric current of motor.Conventionally adopt and carry out wrapped semiconductive outward at conductor and bring as cable provides corresponding withstand voltage properties at motor leading and connecting flexible cord cable, more wrapped polyester belt prevent from insulating embedded conductor sticking on conductor, soldering reliability affected.Semi-conductive tape and polyester belt are wrapped at twice not only increases production cost, and larger space between semi-conductive tape and polyester belt is unfavorable to uniform electric field, affects the stability of electrical property under high pressure conditions.
In addition, for long-term under small-bend radius the motor leading and connecting flexible cord cable in the welding such as dither, Stone Shock, easily cause the problem of the overtired and erosion attack of insulating material, even cause insulating barrier to break and the security incident that causes, have a strong impact on the useful life of cable.
Summary of the invention
In order to solve the technical problem existing in background technology, the present invention proposes a kind of high pressure resistant reinforced insulation motor leading and connecting flexible cord cable, not only eliminate multilayer twining package tape and formed non-uniform electric field, guarantee the stability of electrical property under high pressure conditions; And improved tensile strength and the pliability of cable, extend the useful life of cable.
The high pressure resistant reinforced insulation motor leading and connecting of the one flexible cord cable that the present invention proposes, comprise center fiber rope, many conductors, gap-filler shall, gap-filler shall is arranged between two conductors of arbitrary neighborhood, many conductors, gap-filler shall is around the stranded formation stranding of center fiber rope cable core, conductor is by wire and be coated on successively composite semiconductor on wire shielding lapping layer and ethylene propylene rubber insulated layer forms, composite semiconductor shielding lapping layer comprises interior shield semiconductors belt and outer fiber layer of cloth, outer fiber layer of cloth is closely compound by adhesive-layer and interior shield semiconductors belt, at stranding cable core outer cladding cordage interlacing stratum reticulare, extrude neoprene oversheath outward at cordage interlacing stratum reticulare.
Preferably, the quantity of conductor is 3-8 root.
Preferably, gap-filler shall is that cross section is circular waterproofing rope, and the diameter of waterproofing rope is less than the diameter of wire.
Preferably, the count of cordage interlacing stratum reticulare is at 45%-65%.
Preferably, center fiber rope dipping flame retardant coating.
The present invention's entirety is soft, makes it have less bending radius, anfractuose specific (special) requirements while meeting electric machine winding lead wire use; Adopt cordage interlacing stratum reticulare, the insulating properties of cable is not only strengthened, but also can bear stronger tensile force, has extended useful life; Adopt composite semiconductor shielding lapping layer, not only reduced wrapped operation, reduced the gap between conductor and insulating barrier, guaranteed electric field effectively and uniformly, reduced production process simultaneously, improved production efficiency.
