35kV改性聚丙烯材料性能测试分析及生产问题解决

35 kV Modified Polypropylene Material Performance Test Analysis and Production Problem Solution

研究了35kV改性聚丙烯材料的性能及其生产工艺,对改性聚丙烯材料进行性能测试分析,并对绝缘线芯生产过程中出现的问题进行分析解决。最终通过绝缘线芯的生产制造,发现并解决了机头加温系统、硫化管冷却系统的设备适用性问题,解决了绝缘屏蔽表面不光滑、绝缘线芯胀气鼓包等问题。生产的电缆经过第三方检测机构检测,满足标准要求,也进一步说明了材料性能测试分析结果及生产问题的解决对批量生产出合格的产品起到了重要作用。

In order to study the properties and the production process of the 35 kV modified polypropylene material,the performance of the modified polypropylene material was tested and analyzed to solve the problems in the production process of the cable insulation core.Finally,in the production and manufacturing of cable insulation core,the equipment applicability problem of cross-head heating system and vulcanization tube cooling system was explosed and solved,which solved the technical problems of rough insulation shield surface,expansion and bulge of cable insulation core.The cables produced by using modified polypropylene materials and perfect process technology had been tested by the third-party testing institute,which fully met the standard requirements.It also further explained that the material performance test and analysis results and the solution of production problems play an important role in the mass production of qualified products.
