Abstract
The utility model relates to a high-strength water-blocking cable made of polyvinyl chloride (PVC) elastomeric plastic material, which comprises a cable core and a sheath layer coated around the cable core. The cable core comprises at least one wire and each wire comprises a conductor and an insulating layer wrapped outside the conductor. Bearing hemp ropes are filled around the wire. A water-blocking layer made of low-density polyethylene material is arranged among the bearing hemp ropes and the sheath layer. Multiple strands of soft copper wires are inter-twisted to form the cable conductor. The insulating layer and the sheath layer are made of PVC elastomeric plastic material. According to the technical scheme of the utility model, both the insulating layer and the sheath layer are made of PVC elastomeric plastic material, so that the cable is better in wear resistance, water-blocking performance, stretch-proof property and oil-stain resistance. The unit cost of the PVC elastomeric plastic material is lower than the unit cost of the rubber material, so that the cost of the cable is lowered. Bearing hemp ropes are adopted as the fillings of the cable core, so that the tensile strength and the softness of the cable are improved. The weight of the cable is lowered. Meanwhile, since the water-blocking layer is wrapped outside the external cabling layer of the insulated conductor core of the cable, the water-blocking effect of the cable is obviously improved.
Description
Technical field
The utility model patent relates to field of cables, is specifically related to a kind of polyvinyl chloride elastomer plastic high strength water repellent electric cable.
Background technology
Cable is ubiquitous in life, development along with society, the acceleration of urbanization process, the use of cable is more and more extensive, particularly in fields such as electric power, metallurgy, mining, petrochemical industry, architectural engineerings, the use amount of cable is larger, requires simultaneously cable to want bending good, water resistance is good, in case near the workman that the leak-stopping electricity is worked hurting.The insulating barrier of existing cable and the material of restrictive coating are pure ethylene-propylene rubber material, and complex process in extrusion also will be through high temperature vulcanized, the tail gas pollution atmosphere in the sulfidation.
Summary of the invention
The utility model proposes a kind of polyvinyl chloride elastomer plastic high strength water repellent electric cable for the problem that prior art exists.
The technical solution of the utility model is: a kind of polyvinyl chloride elastomer plastic high strength water repellent electric cable, comprise cable core and be wrapped in cable core restrictive coating on every side, wherein cable core includes a wire at least, described wire comprises conductor and is wrapped in the insulating barrier of conductor outside, be filled with the carrying rope made of hemp around the wire, be provided with the water blocking layer that low density polyethylene (LDPE) is made between the carrying rope made of hemp and the restrictive coating.
Described polyvinyl chloride elastomer plastic high strength water repellent electric cable, cable conductor forms owing to multiply soft copper skein silk closes.
Described polyvinyl chloride elastomer plastic high strength water repellent electric cable, insulating barrier and sheath material are the polyvinyl chloride elastomer plastic.
The beneficial effects of the utility model are: insulating barrier of the present utility model and sheath material all adopt the polyvinyl chloride elastomer plastic increased cable antifriction, block water, stretch-proof, oil resistant be dirty, the polyvinyl chloride elastomer plastic, the material unit price is lower than rubber, has reduced cable cost; The filler of cable core has improved the tensile strength of cable and the pliability of cable for the carrying rope made of hemp, has reduced the weight of cable; At the outer parcel of cable insulation core stranding water blocking layer, so that the block-water effect of cable obviously promotes.
Description of drawings
Fig. 1 is cross-sectional view of the present utility model;
1 is conductor among the figure, and 2 is insulating barrier, and 3 are the carrying rope made of hemp, and 4 is water blocking layer, and 5 is restrictive coating.
Embodiment
Embodiment 1: in conjunction with Fig. 1, a kind of polyvinyl chloride elastomer plastic high strength water repellent electric cable, comprise cable core and be wrapped in cable core restrictive coating on every side, wherein cable core is comprised of a wire, described wire comprises the insulating barrier that conductor and the polyvinyl chloride elastomer that is wrapped in the conductor outside are made, and the polyvinyl chloride elastomer is that polyvinyl chloride resin powder is that base-material adds mixing the forming such as certain proportion ethylene propylene diene rubber, filler, modifier (maintaining secrecy), plasticiser.
Be filled with the carrying rope made of hemp around the wire, the carrying rope made of hemp adopts the plying rope made of hemp, and the rope made of hemp is that the fiber of getting various fibre of flax for textile materials is made.Be provided with the water blocking layer that low density polyethylene (LDPE) is made between the carrying rope made of hemp and the restrictive coating.Cable conductor forms owing to multiply soft copper skein silk closes; Insulating barrier and sheath material are the polyvinyl chloride elastomer.
Embodiment 2: the part identical with embodiment 1 do not repeat, and different is that described cable core forms with wire by 2.
