Pressure and electric current.Generally use in motor leading and connecting flexible cable and outside conductor, carry out wrapped semiconductive bring and carry for cable
For corresponding proof voltage performance, prevent insulation embedded conductor further around bag polyester belt and stick on conductor, impact
Soldering reliability.Semi-conductive tape and the most wrapped production cost that not only increases of polyester belt, and semi-conductive tape and
Bigger space between polyester belt is unfavorable to uniform electric field, affects the stability of electrical property under high pressure conditions.
Additionally, for the long-term motor in the welding such as dither, Stone Shock under small-bend radius
Draw and connect flexible cable, the problem easily causing insulant fatigue and erosion attack, even result in insulating barrier
The security incident ruptured and cause, has a strong impact on the service life of cable.
Summary of the invention
In order to solve technical problem present in background technology, the present invention proposes a kind of high pressure resistant reinforced insulation
Motor leading and connecting flexible cable, not only eliminates multilamellar twining package tape and forms non-uniform electric field, it is ensured that under high pressure conditions
The stability of electrical property；And improve tensile strength and the pliability of cable, extend the use longevity of cable
Life.
The one high pressure resistant reinforced insulation motor leading and connecting flexible cable that the present invention proposes, including center fiber rope, many
Root conductor, gap-filler, gap-filler is arranged between two conductors of arbitrary neighborhood, many conductors, gaps
Filler is around center fiber rope stranded composition stranding cable core, and conductor is by wire and is coated on successively on wire
Composite semiconductor shielding lapping layer and ethylene propylene rubber insulated layer are constituted, in composite semiconductor shielding lapping layer includes
Shield semiconductors belt and outer fiber layer of cloth, outer fiber layer of cloth is tight with interior shield semiconductors belt by adhesive-layer
Close compound, at stranding cable core outer cladding cordage interlacing stratum reticulare, squeeze outside cordage interlacing stratum reticulare
Bag neoprene oversheath.
Preferably, the quantity of conductor is 3-8 root.
Preferably, gap-filler be cross section be circular waterproofing rope, and straight less than wire of the diameter of waterproofing rope
Footpath.
Preferably, the count of cordage interlacing stratum reticulare is at 45%-65%.
Preferably, center fiber rope dipping flame retardant coating.
Entirety of the present invention is soft so that it is have less bending radius, when meeting electric machine winding lead wire use
Anfractuose particular/special requirement；Using cordage interlacing stratum reticulare, the insulating properties of cable is not only strengthened, and
Higher tensile force can also be born, extend service life；Use composite semiconductor shielding lapping layer, no
Only reduce wrapped operation, reduce the gap between conductor and insulating barrier, it is ensured that electricity effectively and uniformly
, decrease production process simultaneously, improve production efficiency.
