Through setting up negative pressure pipe 51 at outer protective layer 5, guide the steam that gets into exhaust pipe 41 pipe, for the steam in the exhaust pipe 41 provides power for the steam in the exhaust pipe 41 passes through negative pressure pipe 51 and discharges fast, accelerates the steam exhaust rate in the exhaust pipe 41, has further effectively improved the moisture resistance of cable, reaches effective improvement cable life's effect. In addition, a one-way water immersion film is provided at the orifice of the negative pressure pipe 51. Through set up one-way soaking film in negative pressure tube 51's mouth of pipe department, when not hindering negative pressure tube 51 with the steam guide discharge cable in the blast pipe 41, effectively avoid external steam to pass through negative pressure tube 51 and get into negative pressure tube 51 in, effectively improved negative pressure tube 51's waterproof performance.
Referring to fig. 3, closed induction coils 42 are equidistantly installed in the moisture-proof layer 4 along the length direction of the cable, the axes of the induction coils are perpendicular to the axis of the cable, and the induction coils 42 and the exhaust pipe 41 are arranged in a staggered manner. By the arrangement of the induction coils 42, when the three lead wires 1 are fed with the alternating current which periodically changes, the induction magnetic fields which periodically changes are generated around the three lead wires 1, and the changing induction magnetic fields cause the magnetic flux in each induction coil 42 to periodically change, so that the induction current which periodically changes is generated in each induction coil 42. According to the heat effect of electric current again, induction coil 42 continuously generates heat for the steam in dampproof course 4 can rapid evaporation dissipation, thereby the inside of drying cable has effectively improved the drying rate of dampproof course 4, and then promotes the humidity resistance of cable, reaches the effect of effectively improving the life of cable.
Referring to fig. 4 and 5, the lead 1 includes a metal core 11, a semiconductor shielding layer 12, an insulating layer 13, an insulating shielding layer 14, a semi-conductive water-blocking layer 15, and a protective sheath 16, which are sequentially disposed from inside to outside. The semiconductive water-blocking layer 15 is made of a semiconductive non-woven fabric. The upper surface and the lower surface of the semiconductive non-woven fabric are both provided with water-absorbing expansion layers 151 in an attached mode. One surfaces of the two water-absorbing expansion layers 151, which are far away from the semi-conductive non-woven fabric, are respectively coated with a one-way water-soaking layer 152, and the one-way water-soaking layer 152 is a one-way water-soaking layer. By providing the semiconductor shield layer 12, occurrence of partial discharge between the conductor and the insulating layer 13 can be effectively prevented. By providing the insulating shield layer 14, partial discharge between the protective cover 16 and the insulating layer 13 can be effectively prevented. Through the arrangement of the semi-conductive waterproof layer 15 and the protective sleeve 16, protection can be provided for the metal core 11, and the moisture resistance of the wire 1 can be effectively improved. And through set up one-way soaking film on semiconduction non-woven fabrics upper and lower surface, can effectively obstruct moisture and get into semiconduction non-woven fabrics, effectively improve semiconduction waterproofing layer 15's waterproof nature. And through the setting of the water-swelling layer 151, even though the single line soaking film in the semi-conductive water-blocking layer 15 outside can't prevent steam to get into because of reasons such as ageing, damage completely, the water-swelling layer 151 also can absorb the steam inflation, draw the interval of two one-way soaking films bigger to prevent further infiltration of moisture, thereby play more effectual effect of blocking water, effectively improved the waterproof performance of wire 1, and then reach the life who improves the cable.
Referring to fig. 4, the insulating and shielding layer 14 is externally provided with a metal shielding layer 17, and the metal shielding layer 17 is formed by weaving a tinned copper wire. Through the setting of metallic shield 17, can effectively improve electric field distribution, metallic shield 17 passes through the electric capacity electric current when the cable normal operating, when the cable takes place the short circuit, also can regard as the passageway of short circuit electric current, and metallic shield 17 also can further improve the compressive capacity of cable simultaneously.
