Abstract
The utility model relates to a split-phase absolute water resistant cross-linked cablem, comprising three water resistant insulating cable cores(1), a filling rope(2), an enclosure layer(3) and an outer protective layer(4), wherein, the three water resistant insulating cable cores(1) are twisted with the filling rope(2) to product a cable. The enclosure layer(3) is made through winding wrapping belts on the cable. A plastic protective gland out of the enclosure layer(3)is made by extrusion, so as to a construct the outer protective layer(4). A water resistant conductor(6) and the water resistant insulating cable cores(1) of the utility model all adopt water resistant structure. The water resistant layer is made by semiconductive material for the aim of resisting water, keeping well electrical contact and assuring operation of the cable safe and reliable. The utility model provides a completely new product for wire and cable production.
Description
The utility model relates to mechanical manufacturing field, exactly belongs to the electric wire mechanical manufacturing field.
At present, the existing waterproofing type crosslinked cable of China in use do not reach conductor vertically block water, insulate outer vertically block water, purpose that sheath radially keeps off tide, and the crosslinked cable majority that China uses be laid in humidity and the higher area of level of ground water, cable cover(ing) in the mill defective and lay in external force damage, joint the time adverse circumstances under, the capital causes moisture to infiltrate insulation, form water tree in causing insulating, finally cause cable breakdown, reduce cable useful life.
The purpose of this utility model just provide a kind of can prevent moisture infiltrate, improve the cable operational reliability, guarantee cable useful life, have and vertically block water and the split-phase type water-proof cross-linked cable of retaining tide radially.
The utility model mainly is made up of three insulated wire cores that block water, gasket for packing, lapping layer, outer jackets, three block water insulated wire cores and the stranded strandings of gasket for packing, and skin is followed successively by lapping layer, outer jacket.The insulated wire cores that blocks water is with water-blocking conductor, semiconductive internal shield, insulating barrier, semiconductive outer shielding layer, two-layer semiconductive water blocking layer, copper strips screen, radially moisture-proof layer and restrictive coating are formed, mainly by the semiconductive water blocking layer, radially moisture-proof layer and restrictive coating reach and vertically block water and the purpose of retaining tide radially.
Introduce the utility model in detail below in conjunction with accompanying drawing.
Fig. 1: the utility model schematic cross-section.
Fig. 2: the utility model insulated wire cores schematic cross-section that blocks water.
Among the figure: 1 is the insulated wire cores that blocks water, and 2 is gasket for packing, and 3 is lapping layer, 4 is outer jacket, 5 is water-blocking conductor, and 6 is the semiconductive internal shield, and 7 is insulating barrier, 8 is the semiconductive outer shielding layer, 9 is the semiconductive water blocking layer, and 10 is the copper strips screen, and 11 is the semiconductive water blocking layer, 12 are moisture-proof layer radially, and 13 is restrictive coating.
The utility model is made up of three insulated wire cores that block water (1), gasket for packing (2), lapping layer (3), outer jacket (4), three insulated wire cores that block water (1) and the stranded stranding of gasket for packing (2), outer coiling twining package tape forms lapping layer (3), outside lapping layer (3), extrude plastic sheath, form outer jacket (4) (see figure 1).The insulated wire cores that blocks water (1) is with water-blocking conductor (5), semiconductive internal shield (6), insulating barrier (7), semiconductive outer shielding layer (8), semiconductive water blocking layer (9), copper strips screen (10), semiconductive water blocking layer (11), radially moisture-proof layer (12) and restrictive coating (13) composition, and the water-blocking conductor skin is followed successively by semiconductive internal shield (6), insulating barrier (7), semiconductive outer shielding layer (8), semiconductive water blocking layer (9), copper strips screen (10), semiconductive water blocking layer (11), radially moisture-proof layer (12) and restrictive coating (13) (see figure 2).Water-blocking conductor (5) can be combined by many copper conductors or aluminum conductor and the water-proofing powder that is filled in the gap; Conductor also can by many copper conductors or aluminum conductor and waterproofing rope is stranded forms.
The utility model is mainly realized full block-water performance respectively by three insulated wire cores that block water (1), the material water-proof material that the water blocking layer of the insulated wire cores that blocks water (1) uses all is a semiconductive section bar material, promptly realized blocking water, kept electrical property well to contact again, guaranteed that cable is safe and reliable to operation.Water-blocking conductor (5) is to add water-proofing powder or stranded by many copper conductors or aluminum conductor and waterproofing rope in the gap of many copper conductors or aluminum conductor equably, can reach the good purpose that vertically blocks water; Vertical alclad plastic composite strip and extrude the acting in conjunction of oversheath (13) can be guaranteed good radially retaining tide function.The utility model provides a kind of completely new product for electric wire manufacturing field.
