Description
Technical field
Composite high-voltage insulator flexible cord is the utility model is related to, it is more particularly to a kind of to be used for high pressure resistant impact device connection system
Soft high pressure resistant cable.
Background technology
Common high-voltage line, it is use homogenous material as insulating barrier or using semi-conductive layer more, when using homogenous material for
It can bear to use voltage, generally increase insulation thickness, cause thickness larger, the outside diameter of cable goes up, and cable hardness is larger.Absolutely
Edge material and semiconductive material compound tense, semiconductive material poor processability, and hardness is big, causes cable flexibility poor, to making
It can be made troubles during with side using operation, and common high-voltage line is relatively low to ambient mechanical physical property requirements.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of softness, has the good mechanical thing such as cracking resistance
The composite high-voltage insulator flexible cord for high pressure resistant impact device for the features such as rationality energy, electrical insulation capability are good, high pressure resistant.
The utility model to achieve the above object, is adopted the technical scheme that：A kind of composite high-voltage insulator flexible cord, it is special
Sign is：Including tinned wird conductor, polyvinyl chloride inner insulating layer, low density polyethylene (LDPE) external insulation layer, EP rubbers sheath；
A strata vinyl chloride inner insulating layer is extruded outside the tinned wird conductor, is extruded outside polyvinyl chloride inner insulating layer
One layer of low density polyethylene (LDPE) external insulation layer, one layer of EP rubbers sheath is extruded outside low density polyethylene (LDPE) external insulation layer.
The beneficial effects of the utility model are：Using tinned wird conductor, there is good solderability and inoxidizability.Adopt
Insulated with polyvinyl chloride and polyethylene sublevel, there is excellent electric property, it is ensured that cable is reduced while cable voltage
Entire outer diameter, the larger polyvinyl chloride of dielectric constant is placed on internal layer, is homogenized field strength, polyethylene insulation shares residue in outer layer
Voltage, makes the field strength on core surface reduce as far as possible, and the field strength of insulating exterior improves as far as possible.Sheath is using 105 DEG C high electricity
Resistance rate EP rubbers, EP rubbers have excellent dielectric constant, and electricity can also be further met while can sharing voltage
The pliability of cable, it with reduce thickness, can ensure that the softness of cable uses characteristic.
In a word, composite high-voltage insulator flexible cord, it is soft, high pressure resistant.Softness, minimum bending radius are 6 times of outside diameters of cable.Insulation
Performance is good, high pressure resistant, reaches as high as direct current 40kV.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, a kind of composite high-voltage insulator flexible cord, including it is tinned wird conductor 1, polyvinyl chloride inner insulating layer 2, low
Density polyethylene external insulation layer 3, EP rubbers sheath 4.
A strata vinyl chloride inner insulating layer 2 is extruded outside tinned wird conductor 1, is extruded outside polyvinyl chloride inner insulating layer 2
One layer of low density polyethylene (LDPE) external insulation layer 3, the EP rubbers of a floor height resistivity is extruded outside low density polyethylene (LDPE) external insulation layer 3
Sheath 4.
This cable polyvinyl chloride inner insulating layer 2, the material that low density polyethylene (LDPE) external insulation layer 3 is two kinds of differing dielectric constants
Material, can be with reduce thickness using sublevel insulating forms, and resistance to pressure is strong, and flexibility is good.
Common high pressure resistant cable cover(ing) is mostly to irradiate pvc sheath, needs to irradiate after extrusion, and not soft, and this cable is adopted
With EP rubbers material, there is good elasticity, flexibility is higher during use.
