Description
Technical field
This utility model relates to power cable field, specifically a kind of termite-proof water-tree-resistantmedium medium voltage power cable that blocks water of environment-friendly type.
Background technology
Power cable in most of the cases uses polrvinyl chloride or polythene material as oversheath, but in the environment of humidity is rainy, common cross-linked polyethylene insulated cable does not possess the ability of water resistant tree and termite-proof, during life-time service, have portion of water and invade in insulation, cable, under the common effect of electric field and water, produces in insulation and is shaped like in dendritic containing aquaporin, referred to as water tree.Water tree can use the increase of time to be grown into along with cable, also can result in generating electric branch, eventually result in puncturing of cable insulation, thus affect the transmission of electric power under accidental overvoltage effect.
Summary of the invention
The purpose of this utility model is, overcomes the defect of existing power cable, it is provided that a kind of by composite jacket form termite-proof, block water, water-tree-resistantmedium medium voltage power cable.
In order to achieve the above object, this utility model is achieved in that
A kind of termite-proof water-tree-resistantmedium medium voltage power cable that blocks water of environment-friendly type, it includes insulated wire cores and is added, by three insulated wire cores, the cable core that the gasket for packing stranding that blocks water is stranded, and described insulated wire cores is enclosed with conductor shield, water resistant tree insulating barrier, insulation screen, copper strip shielding layer the most successively；The most wrapped lapping layer that blocks water in cable core surface, Low Density Polyethylene restrictive coating, plastic-aluminum combined restrictive coating, Low Density Polyethylene restrictive coating, nylon sheath wire layer and the high density polyethylene (HDPE) restrictive coating of three insulated wire cores strandings.
The termite-proof water-tree-resistantmedium medium voltage power cable that blocks water of described environment-friendly type, the conductor shield being wrapped in outside insulated wire cores, water resistant tree insulating barrier, insulation screen are three-layer co-extruded structure.
The termite-proof water-tree-resistantmedium medium voltage power cable that blocks water of described environment-friendly type, water resistant tree insulating barrier is crosslinked polyetylene insulated layer.
Described cable uses water-blocking conductor, can effectively stop moisture to migrate along conductor；Use the gasket for packing that blocks water during described cable cabling, can effectively stop moisture longitudinal diffusion.
This cable uses aluminium-plastic tape sheath, moisture can be effectively stoped radially to invade cable and then reduce the probability of the initiation of water tree and growth, use the water resistant tree cross-linked polyethylene insulating material of independent development as water resistant tree layer, reduce the impurity at insulation and shield interface and defect by conductor shield, water resistant tree insulating barrier, the three-layer co-extruded technology of insulation screen, effectively suppress initiation and the growth of water tree in cable insulation；Low Density Polyethylene sheath, nylon sheath, high density polyethylene (HDPE) sheath is used to ensure that cable exempts from termite destruction the most further.

Detailed description of the invention
This utility model is further illustrated below by way of specific embodiment.
As shown in Figure 1, a kind of termite-proof water-tree-resistantmedium medium voltage power cable that blocks water of environment-friendly type, it includes insulated wire cores 1 and is added, by three insulated wire cores 1, the cable core that the gasket for packing stranding that blocks water is stranded, and described insulated wire cores 1 is enclosed with conductor shield 2, water resistant tree insulating barrier 3, insulation screen 4, copper strip shielding layer 5 the most successively；The most wrapped lapping layer 7 that blocks water in the cable core surface of three insulated wire cores 1 strandings, Low Density Polyethylene restrictive coating 8, plastic-aluminum combined restrictive coating 9, Low Density Polyethylene restrictive coating 10, nylon sheath wire layer 11 and high density polyethylene (HDPE) restrictive coating 12, arrange the implant that blocks water in the gap between three insulated wire cores 1.
The termite-proof water-tree-resistantmedium medium voltage power cable that blocks water of described environment-friendly type, the conductor shield 2 being wrapped in outside insulated wire cores 1, water resistant tree insulating barrier 3, insulation screen 4 are three-layer co-extruded structure.
The termite-proof water-tree-resistantmedium medium voltage power cable that blocks water of described environment-friendly type, water resistant tree insulating barrier 3 is crosslinked polyetylene insulated layer.
Described cable uses water-blocking conductor, can effectively stop moisture to migrate along conductor；Use the gasket for packing that blocks water during described cable cabling, can effectively stop moisture longitudinal diffusion.
This cable uses aluminium-plastic tape sheath, moisture can be effectively stoped radially to invade cable and then reduce the probability of the initiation of water tree and growth, use the water resistant tree cross-linked polyethylene insulating material of independent development as water resistant tree layer, reduce the impurity at insulation and shield interface and defect by conductor shield, water resistant tree insulating barrier, the three-layer co-extruded technology of insulation screen, effectively suppress initiation and the growth of water tree in cable insulation；Low Density Polyethylene sheath, nylon sheath, high density polyethylene (HDPE) sheath is used to ensure that cable exempts from termite destruction the most further.
