低嵌入绝缘填充式护套阻水动力电缆的研制

Development of Low-embedded Insulation Filled Sheathed Hydrodynamic Cable

借助地方政府项目集中推介会的东风,苏州宝兴与中东某外方公司建立了长期的业务合作关系,并初步达成了某防爆防水场合下使用的动力电缆供货意向。双方在技术联络时,外方公司仅对电缆的工作电压(6.35/11kV)、设计规格(3×240mm2)和部分派生特性(低放电、耐冲击、纵向阻水等)提出了较为粗略的要求,并要求苏州宝兴结合自身的技术优势,完成产品整体设计和后续的批量交付。苏州宝兴攻克产品设计、工艺、装备、质控和配套环节等一系列难题,最终保质保量顺利完成了该出口电缆产品的交付。本文重点叙述了从导体、绝缘、屏蔽、成缆、护套、包装等关键环节的主要思路。

With the help of the local government project centralized promotion meeting,and the effective efforts of the marketing department,Suzhou Baoxing established a long-term business cooperation relationship with a foreign company in the Middle East,andinitially reached the intention to supply power cables used in an explosionproof and waterproof occasion.During the technical contact between two parties,the foreign company only put forward relatively rough requirements for the cable’s operating voltage(6.35/11kV),design specifications(3×240mm2)and some derived characteristics(low discharge,impact resistance,longitudinal water resistance,etc.),and required Suzhou Baoxing to complete the overall product design and subsequent batch delivery based on its own technical advantages.Suzhou Baoxing overcame a serious of difficulties in product design,technology,equipment,quality control and supporting links,and finally successfully completed the delivery with quality and quantity guaranteed.This paper focuses on the main ideas of conductor,insulation,shielding,cable building,sheath,packaging and other key links.
