Abstract
The utility model provides a non-magnetic stainless steel tape armored waterproof type cable and relates to a non-magnetic stainless steel tape armored waterproof type crosslinking power cable. In an aluminum plastic vertically wrapped waterproof layer of the cable, the metallic tapes are vertically wrapped by the single-layer plastic coated aluminum tapes, the lap width between the metallic tapes is no less than 6 millimeters, and the seams are glued by melted glue and then a polyethylene inner sheath is extruded and wrapped; the sheath not only is used as the vertical waterproof layer, but also has an action of an armored buffer layer; and simultaneously, the outside of the aluminum plastic vertically wrapped waterproof layer is directly armored by the non-magnetic stainless steel tapes. The cable has the advantages of being reasonably and skillfully designed, effectively improving the short-circuit ability of the cable shield, meeting the short-circuit requirement on direct grounding, reinforcing the radial and vertical waterproof abilities of the cable, and consequently improving the mechanic safety and electric safety of the cable operation.
Description
Technical field
The utility model discloses a kind of non-magnetic stainless steel band armouring water proof type cross-linked power cable, especially when satisfying normal electricity transmission, improved cable radially, vertical water resistance, guaranteed the machine security and the electrical safety of cable.
Background technology
All adopted nonmagnetic substance when being used for the single-core cable armouring of ac circuit at present, but owing to can't satisfy directly grounded short circuit requirement, also just can't eliminate because variation of temperature, cause cable material to expand with heat and contract with cold and cable is exerted an adverse impact, when particularly using simultaneously, improved the cable waterproof performance demands is also corresponding for the railway system.
Summary of the invention
The utility model provides a kind of non-magnetic stainless steel band armouring water proof type cross-linked power cable; This cable can be when satisfying normal electricity transmission, improve cable radially, vertical water resistance, guarantee the machine security and the electrical safety of cable.
The utility model is to realize by following technical solution: this cable comprises the copper conductive core line, its peripheral core of carrying out conductor shield, insulating barrier and insulation screen composition cable by three-layer co-extruded bag successively; Core has the copper strips lapped shielding layer outward, and its outer wrapped water-blocking buffer layer is the vertical packaging waterproof layer of plastic-aluminum again, adds non-magnetic stainless steel band armour, and outermost layer extrudes the polyvinyl chloride outer jacket; It is characterized in that in the vertical packaging waterproof layer of described plastic-aluminum, metal tape is the vertical bag of individual layer plastic-coated aluminium strip, metal tape and metal tape lap width are not less than 6mm, and seam crossing is bonding by melten gel, extrudes the polyethylene inner sheath again; This sheath promptly as vertical watertight composition, has played the effect of armouring resilient coating again; Outside the vertical packaging waterproof layer of plastic-aluminum, directly adopted non-magnetic stainless steel to bring the luggage armour into simultaneously.
The utility model reasonable idea, ingenious, it not only can effectively improve the short-circuit capacity of cable shield, can satisfy directly grounded short circuit requirement, strengthened simultaneously cable radially, vertical water resistance, thereby improved the machine security and the electrical safety of cable operation.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
As shown in Figure 1, this cable comprises copper conductive core line 1, its peripheral core of carrying out conductor shield 2, insulating barrier 3 and insulation screen 4 composition cables by three-layer co-extruded bag successively; Core has copper strips lapped shielding layer 5 outward, and its outer wrapped water-blocking buffer layer 6 is the vertical packaging waterproof layer 7 of plastic-aluminum again, adds non-magnetic stainless steel band armour 9, and outermost layer extrudes polyvinyl chloride outer jacket 10; In the vertical packaging waterproof layer of plastic-aluminum, metal tape is the vertical bag of individual layer plastic-coated aluminium strip, and metal tape and metal tape lap width are not less than 6mm, and seam crossing is bonding by melten gel, extrudes polyethylene inner sheath 8 again; This sheath promptly as vertical watertight composition, has played the effect of armouring resilient coating again; Outside the vertical packaging waterproof layer of plastic-aluminum, directly adopted non-magnetic stainless steel to bring the luggage armour into simultaneously.This cable can effectively improve the short-circuit capacity of cable shield, can satisfy directly grounded short circuit requirement, strengthened simultaneously cable radially, vertical water resistance.
