The utility model discloses the power cable that blocks water through conductor water blocking tape and semiconduction water blocking tape to block water to pack the rope that blocks water between the cable core, the cable core outward around package ZDS water blocking tape, reach between the inside and outside sheath around package ZSD water blocking tape, make the cable have good vertical and radial water blocking performance.
Description
Technical field
The utility model relates to a kind of power cable, more particularly, relates in particular to a kind of crosslinked polyetylene insulated water-resistant power cable, belongs to the cable technology field.
Background technology
Cable is in long-term use, because the erosion of moisture and moisture content causes transmission performance to descend; Influence the normal use of cable; Particularly at southern area, through moisture, rainy, level of ground water is high, the water preventing ability of the cable of the buried-pipe laying important that seems.At present, the waterproof on the market and the cable that blocks water adopt metallic sheath to realize for along radially the blocking water of the cross-section of cable, for example, with aluminium or plastic-aluminum combined sheath as waterproof, water-blocking element.But this kind mode of blocking water is at core extrernal resistance water, in case there is water to flow into core, then block-water effect is bad, is prone to puncture insulation sheath, causes the damage of cable.
The utility model content
The purpose of the utility model is the deficiency to above-mentioned prior art, and a kind of crosslinked polyetylene insulated water-resistant power cable is provided, this cable have good radially with vertical block-water performance.
For realizing above-mentioned purpose, a kind of crosslinked polyetylene insulated water-resistant power cable that the utility model provided comprises cable core and restrictive coating; Said cable core is by three insulated cores combination stranding; Every insulated core comprises that conductor reaches from inside to outside the conductor waterstop of wrapped conductor, semiconductive waterstop, conductor shield, insulating barrier, insulation screen and metal screen layer successively, the outer wrapped two layers of ZDS waterstop of cable core, and the gap between ZDS waterstop and cable core is filled with waterproofing rope; The ZDS waterstop is extruded with inner sheath outward; The outer wrapped wire armoring of inner sheath, the outer wrapped one deck ZSD waterstop of wire armoring, the ZSD waterstop is extruded with oversheath outward.
The crosslinked polyetylene insulated water-resistant power cable of the utility model blocks water to conductor through conductor waterstop and semiconductive waterstop; And between cable core, fill wrapped ZDS waterstop outside waterproofing rope, the cable core, and inside and outside sheath between wrapped ZSD waterstop, make cable have good vertically with block-water performance radially.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is done further to specify, but do not constitute any restriction the utility model.
Fig. 1 is the cross section structure sketch map of the crosslinked polyetylene insulated water-resistant power cable of the utility model.
Among the figure: the 1-conductor; 2-conductor waterstop; 3-semiconductive waterstop; The 4-conductor shield; The 5-insulating barrier; The 6-insulation screen; The 7-metal screen layer; The 8-waterproofing rope; The 9-ZDS waterstop; The 10-inner sheath; The 11-wire armoring; The 12-ZSD waterstop; The 13-oversheath.
Embodiment
For further understanding the summary of the invention and the characteristics of the utility model, the following instance of giving an example now, and conjunction with figs. specifies as follows:
With reference to accompanying drawing 1; The crosslinked polyetylene insulated water-resistant power cable of the utility model; Comprise cable core and restrictive coating; Cable core is by three insulated cores combination stranding, and every insulated core comprises that conductor 1 reaches conductor waterstop 2, semiconductive waterstop 3, conductor shield 4, insulating barrier 5, insulation screen 6 and the metal screen layer 7 of wrapped successively conductor 1 from inside to outside.Wherein, conductor waterstop 2 and semiconductive waterstop 3 are that conductor 1 is formed water blocking layer; Conductor shield 4, insulating barrier 5, insulation screen 6 adopt three-layer co-extruded, totally-enclosed chemical crosslinking technology to be extruded in outside the semiconductive waterstop 3; The composite shielding layer that conductor shield 4 is formed for wrapped semiconductive waterstop and the crosslinked semi-conductive layer that extrudes; Insulating barrier 5 adopts crosslinked polyethylene as insulating material, the crosslinked semi-conductive layer of insulation screen 6 for extruding; Metal screen layer 7 is the soft copper band, and is overlapping wrapped outside insulation screen 6.
Become the outer wrapped two layers of ZDS waterstop 9 of cable core, fill through waterproofing rope 8 in the space between ZDS waterstop 9 and cable core, to reach the purpose that vertically blocks water; The ZDS waterstop 9 outer inner sheaths 10 that are extruded with, inner sheath 10 outer wrapped zinc plated mild carbon steel silk armourings 11, wire armoring 11 outer wrapped one deck ZSD waterstops 12, the ZSD waterstop 12 outer oversheaths 13 that are extruded with, it is high density polyethylene (HDPE) that inside and outside sheath adopts material; Wrapped wire armoring 11 and ZSD waterstop 12 make cable possess good vertical block-water performance between inner sheath 10 and oversheath 13, and the radially block-water performance of cable relies on the duplex sheath structure of inner sheath 10 and oversheath 13 to realize.
