Abstract
The utility model relates to an all-round water-proof cross-linked cable, consisting of three insulation cable cores(1), a water-proof filling rope(2), a water-proof layer(3), a diameter direction moisture-proof layer(4) and an outer protective layer(5). The three insulation cable cores(1) and the water-proof filling rope(2) are connected with each other to form a cable. The outer layer is provided with water-proof layer(3), diameter direction moisture-proof layer(4) and the outer protective layer(5) in serial. as the utility model utilizes a water-proof conductor(6), the water-proof filling rope(2) and the water-proof layer(3), the utility model has the advantages of not only ensuring the good water-proof and moisture-proof function, but also ensuring the good electric performance and ensuring the safety and reliability of the cable operation. The utility model provides a new product for the antenna and cable production filed.
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 provide a kind of can prevent moisture infiltrate, improve the cable operational reliability, guarantee cable useful life, have and vertically block water and the all-round water-proof cross-linked cable of retaining tide radially.
The utility model mainly by three thoroughly do away with edge cores, the gasket for packing that blocks water, water blocking layer, radially moisture-proof layer and outer jacket are formed; The insulated wire cores and the stranded stranding of gasket for packing that blocks water, skin is followed successively by water blocking layer, radially moisture-proof layer, outer jacket, the used conductor of insulated wire cores adopts stop water, again by the gasket for packing that blocks water, water blocking layer and vertically blocking water and retaining tide radially of moisture-proof layer radially, can prevent that moisture from infiltrating, guarantee cable useful life.
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.
Among the figure: 1 is insulated wire cores, and 2 are the gasket for packing that blocks water, and 3 is water blocking layer, and 4 are moisture-proof layer radially, and 5 is outer jacket, and 6 is water-blocking conductor, and 7 is internal shield, and 8 is insulating barrier, and 9 is outer shielding layer, and 10 is the semiconductive water blocking layer, and 11 is the copper strips screen.
The utility model is to thoroughly do away with edge core (1), the gasket for packing that blocks water (2), water blocking layer (3) radially moisture-proof layer (4) and outer jacket (5) composition with three, three thoroughly do away with edge core (1) and block water the stranded stranding of gasket for packing (2), outer wrapped semiconductive waterstop forms water blocking layer (3), vertical alclad plastic composite strip forms radially moisture-proof layer (4) outside water blocking layer (3), radially extrude vinyon again outside the moisture-proof layer (4), forming outer jacket (5) (see figure 1).Wherein, insulated wire cores (1) is made up of water-blocking conductor (6), semiconductive internal shield (7), insulating barrier (8), semiconductive outer shielding layer (9), semiconductive water blocking layer (10), copper strips screen (11), water-blocking conductor (6) skin is followed successively by semiconductive internal shield (7), insulating barrier (8), semiconductive outer shielding layer (9), semiconductive water blocking layer (10), copper strips screen (11) (see figure 2), and insulating barrier (8) is a crosslinked polyethylene; Water-blocking conductor (6) 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 material water-proof material that gasket for packing (2), water blocking layer (3) use that blocks water in the utility model structure all is a semiconductive section bar material, has promptly realized blocking water, and keeps electrical property well to contact again, guarantees that cable is safe and reliable to operation.Water-blocking conductor (6) 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 (5) can be guaranteed good radially water-proof function.The utility model provides a kind of completely new product for electric wire manufacturing field.
