Operational management require improve constantly rural area wide geographic area, its product structure by compacted stranded conductor, semiconductive internal shield with
And the crosslinked polyetylene insulated part of layer three composition of weather resistant, it is built on stilts different from common 1KV because its conductive voltage is higher ranked
Insulated cable, its uniformity and insulating barrier smooth degree to electric-field intensity has higher requirement, therefore its product structure must
Inner semiconductor layer must be included.
The method of production 10KV aerial insulated cables is the three-layer co-extruded dry cross-linking production line productions of 6-35KV CCV at present,
As shown in figure 1, including an inner shield core rod 1 and the insulation core rod 2 being nested on the outside of inner shield core rod 1, the He of inner shield core rod 1
Space between insulation core rod 2 is internal shield extrusion zone 3, in the nested public mould 4 in the outside of insulation core rod 2, insulation core rod 2
Space between public mould 4 is insulation extrusion area 5, in the outer nested external shield die sleeve 7 of public mould 4, the public He of mould 4
Gap between external shield die sleeve 7 is external shielding layer extrusion zone 9, and it is that three extruding machines pass through special set of molds that it, which extrudes principle,
Close and runner design is by internal shield, insulating barrier, external shielding layer jointly extrusion to conductor thread core, realize three-layer co-extruded effect
Really；But current 10KV aerial insulated cables structure is only comprising two layers of extrusion structure of internal shield and insulating barrier, without outer half
Conductive shielding layer, therefore when being produced using the three-layer co-extruded dry cross-linking production line of CCV catenary suspension type continuous vulcanizations, in extrusion
In, SI semi-insulation material can be caused to be trapped at external shield runner, simultaneously as the extension of high temperature action and time, delay it is exhausted
The meeting aging of edge material forms thermoset particles, and with the production of core, desultory delay on the insulating layer, causes producing
The continual micelle for taking aging out of in journey, causes crosslinking core pimple occur, has had a strong impact on product quality, and also not beautiful
See.The method that present each manufacturing enterprise generally uses is shut down in time after normal boot-strap about 2*24h, cleaning head and separate out it is old
Glue, then heating is driven again again, is wasted substantial amounts of manpower, the energy and raw material, is greatly reduced production efficiency, adds
Manufacturing cost.
Utility model content：
There is provided a kind of 10KV aerial insulated cables extrusion mould special in order to make up the deficiencies in the prior art for the utility model
Tool, its reasonable in design has prevented the situation generation that insulating materials is trapped on outer die casing, it is to avoid the micelle of aging is attached to
On aerial insulated cable core；In addition, line speed can be greatly promoted, it is stagnant that continuous production for a long time will not produce Insulation Material
Phenomenon and insulating cement aging phenomenon are stayed, product surface plasticizing is good when realizing continuous production, production efficiency is improved, product quality
The purpose such as guaranteed, efficiently solves problems of the prior art.
The utility model is to solve the technical scheme that is used of above-mentioned technical problem：
A kind of 10KV aerial insulated cables extrusion mould special tool, including an inner shield core rod and it is nested in inner shield core rod
The insulation core rod in outside, the space between inner shield core rod and insulation core rod is internal shield extrusion zone, on the outside of insulation core rod
A nested public mould, the space between insulation core rod and public mould is insulation extrusion area, in the bottom of public mould
Side wall is provided with a circular protrusions, the external shield of the falling convex die sleeve that the bottom of clamp one caves inward in circular protrusions, external screen
The lateral wall and public die end madial wall for covering die sleeve are abutted against, in inner shield core rod, insulation core rod, public mould and outer
The through hole that current supply cable is passed through is equipped with the central shaft for shielding die sleeve.
The utility model uses such scheme, its reasonable in design, using the combination that public mould and insulator die set are nested
Mode, by closely connecting, it is ensured that external shielding layer expulsion area does not have any gap, has prevented insulating materials and has been trapped in external mold
Situation about putting occurs, it is to avoid the micelle of aging is attached on aerial insulated cable core；In addition, in the influence of no aging micelle
In the case of outward appearance and the hot extension of the insulated wire cores that ensure and cooling strain are standard compliant, line speed can be greatly promoted, long
Time Continuous production will not produce Insulation Material trapping phenomena and insulating cement aging phenomenon, product table dough model when realizing continuous production
Change the purposes such as good, production efficiency is improved, product quality is guaranteed.
