具体实施方式
如图1所示,本发明公开了一种煤矿用加强型超重型便携式电缆。
为使电缆达到高耐磨性、高柔软性及抗拉性,提高电缆的使用寿命,申 请人选用以下材料制作电缆。
1、导体:采用GB/T 3956-2008要求的第6类镀锡软导体,经多股束绞 而成,结构更加柔软。(镀锡铜导体可有效防止导体在恶劣环境下产生腐蚀 及氧化现象)
2、导体屏蔽:采用包带-挤出组合屏蔽,包带采用加强半导电尼龙带直 接重叠绕包在导体上,紧接着采用10kV级三元乙丙型半导电内屏蔽料挤出 屏蔽层,导体屏蔽可起到均匀电场作用。
3、绝缘层:采用10kV级高压电缆用超高强度的三元乙丙橡皮挤出,橡 皮具有优越的电绝缘性能,耐老化、耐候性及耐化学腐蚀性好,并具有较强 的冲击弹性。
4、绝缘屏蔽:采用10kV级三元乙丙型半导电外屏蔽料,导体屏蔽层、 绝缘层、绝缘屏蔽层采用三层共挤工艺,全封闭硫化。
5、金属屏蔽层:相线芯采用镀锡铜丝+纤维纱编织结构,防止外界的电 磁干扰。
6、接地检测线:导体采用GB/T 3956-2008要求的第6类镀锡软导体, 经多股束绞而成,结构更加柔软。(镀锡铜导体可有效防止导体在恶劣环境 下产生腐蚀及氧化现象)。绝缘采用聚丙烯绝缘料,该材料密度小、强度大, 硬度高、弹性好,具有突出的抗弯曲疲劳性,反复弯曲不易损伤。并具有一 定程度地耐冲击性,机械性能强韧,抗多种有机溶剂和酸碱腐蚀。聚丙烯材 料几乎不吸水,绝缘性能不受湿度的影响,适合用于井下电缆的绝缘层材料。
7、接地线:导体采用GB/T 3956-2008要求的第6类镀锡软导体,经多 股束绞而成,结构更加柔软。(镀锡铜导体可有效防止导体在恶劣环境下产 生腐蚀及氧化现象)。
8、内护层:采用重型氯化聚乙烯橡皮,既可以保证缆芯的圆整度,也 防止了屏蔽层对外护套造成的磨损。
9、加强层:采用芳纶丝编织结构,极大地增加了电缆的机械强度与抗 拉力,稳定的结构和均匀地受力使得电缆的整体抗拉力是普通电缆的2~3 倍。(芳纶丝为一种合成纤维,具有超高强度、高模量、耐高温、耐酸耐碱、 重量轻等优良性能,其强度是钢丝的5~6倍,模量为钢丝或玻璃纤维的2~3 倍,韧性是钢丝的2倍,而重量仅为钢丝的1/5左右,在560度的温度下, 不分解、不熔化。)
10、外护套层:采用超重型氯化聚乙烯橡皮材料,可满足耐热、耐油、 耐化学腐蚀、耐摩擦等要求,并增强了环境耐受性。
电缆制作工艺:
1、导体:动力线芯、接地检测线及接地导体的导体均采用满足GB/T 3956-2008要求的第6种镀锡软铜导体。绞合的导体不应有缺丝、松股和断 股的现象,导体绞合均匀、紧密,表面应光洁,不得有油污、毛刺等缺陷。
2、三层共挤:动力线芯的挤出导体屏蔽、绝缘、绝缘屏蔽采用三层共 挤加工工艺,全封闭蒸汽交联。动力线芯挤出前采用加强半导电尼龙带直接 重叠绕包在导体上,紧接着采用10kV级三元乙丙橡皮型半导电橡皮挤出导 体屏蔽,包带-挤出组合屏蔽的任一点厚度都不应小于0.6mm,挤出导体屏蔽 层的外侧与绝缘层内表面应接触光滑。绝缘采用10kV级高压电缆用加强型 三元乙丙橡皮(EPR),绝缘的抗张强度不小于8.3Mpa,100%伸长时拉伸应力 不小于3.5MPa,断裂伸长率不小于150%,绝缘层任一点的最小厚度不小于 标称值×90%mm,且偏心度不大于10%。绝缘应紧密粘结到挤出导体屏蔽上, 绝缘横断面上无目力可见气泡和砂眼等缺陷。绝缘屏蔽采用10kV级三元乙 丙橡皮型半导电橡皮挤出,绝缘屏蔽应该能够剥离下来而不损伤绝缘。绝缘 屏蔽、绝缘、导体屏蔽各层之间均要包覆密实,各层及各层间不得有焦粒、 气隙或杂质存在,线芯表面应光滑,无明显绞线凸纹,不应有尖角、颗粒、 烧焦或擦伤的痕迹。
3、复合屏蔽层:动力线芯三层共挤后采用加强半导电尼龙带重叠绕包 在线芯上,重叠宽度不小于带宽的10%,在其外采用镀锡铜绞合股线与聚对 苯二甲酸乙二酯纱线交叉编织组成复合屏蔽,铜绞合股线以右向与以左向的 纱线进行交叉编织形成编织层。编织层节距为动力线芯节圆直径的4.5倍, 铜的覆盖面积不小于84%。动力线芯的标识采用着色的纱线裹挟在复合屏蔽 的纱线里,着色纱线采用红色、白色、蓝色。该复合屏蔽结构可有效地防止 外界的电磁对电缆的干扰,也提高了电缆的柔软度。
4、接地检测线:采用聚丙烯绝缘料挤包,聚丙烯绝缘密度小、强度大, 硬度高、弹性好,具有突出的抗弯曲疲劳性,反复弯曲不易损伤。可有效地 保证线芯的使用寿命。
5、成缆:成缆时三根动力线芯依次按照红色、白色、蓝色顺时针方向 排列,并将接地检测线与接地导线放置在相线芯外侧间隙中。接地检测线放 置在白色和蓝色动力线芯间隙间。两根接地导线分别放置在蓝色、红色和红 色、白色线芯间隙中,并与相线芯的金属屏蔽层紧密接触。将所有线芯与填 充材料一起左向绞合成缆,最大的成缆节距为相线芯外径的21倍。
6、内护套:采用重型氯化聚乙烯橡皮混合物挤出,橡皮抗张强度不小 于13.5Mpa,200%伸长时拉伸应力不小于4.0MPa。橡皮紧贴成缆线芯而不粘 连成缆线芯,并嵌入填满线芯之间的外部间隙。既可以保证缆芯的圆整度, 也防止了屏蔽层对外护套造成的磨损。
7、加强层:采用多股芳纶丝交叉编织结构加强外护套,加强层放置在 外护套厚度不小于护套总厚度的50%至80%之间,护套总厚度包括内护套和 外护套的厚度。编织节径比为缆芯外径的2~4倍,编织覆盖密度不小于60%, 可有效地保证内外护套粘连,加强护套的抗拉强度。
8、外护套:采用超重型氯化聚乙烯橡皮混合物挤出,抗张强度不小于 16.5Mpa,200%伸长时拉伸应力不小于5.0MPa,撕裂强度不小于8kN/mm。外 护套施加在加强层上,并使其与加强层下面的内护套有效粘结,外护套的平 均厚度不小于规定的标称厚度,任一点的最小厚度不小于标称厚度× 90%-0.1mm。外护套可满足耐热、耐油、耐化学腐蚀、耐磨和耐油等要求, 并增强了环境耐受性。
申请人将研发的MCPTJB-GC-6/10kV 3×35+2×16+1×10加强型超重型 便携橡套电缆进行了抗拉伸、耐老化、耐油、耐磨等主要性能的测试,结果 显示所有性能均高于设计要求。
