Description

新能源汽车充电桩电缆
技术领域
本发明涉及一种新能源汽车充电桩电缆，属于电线电缆领域。
背景技术
我国地域辽阔，资源丰富。随着我国经济建设不断发展，人民生活水平不断提高，汽车已进入家庭，石油的需求量也越来越大。
我国汽车的燃料主要来源于石油，石油的需求量越来越大，因为石油的储量有限所以石油面临枯竭的危险，同时也严重的污染环境，为此国家提倡开发各种新能源汽车，新能源汽车的动力来源于电力，所以要大力建设新能源汽车充电设施，充电设施和新能源汽车之间需要电缆来链接也就是充电桩电缆。由于汽车在充电时充电桩电缆和加油站的加油管一样到处拖拉、弯曲、碾压有时还受到各种腐蚀和水的浸湿而导致电缆短路或断路，使充电桩不能正常工作。这样就要求一方面充电场所应具备有抗拖拉、弯曲、碾压和防腐蚀防水浸湿的功能，这显然是难以做到的，另一方面我们必须考虑电缆本身应具有抗拖拉、弯曲、碾压和防腐蚀防水浸湿以及阻燃等性能，即在一定条件下电缆具有抗拖拉、弯曲、碾压和防腐蚀防水浸湿以及阻燃等性能要好，迄今为止还没有一种具有优异抗拖拉、弯曲、碾压和防腐蚀防水浸湿以及阻燃等性能的充电桩电缆。
发明内容
为克服上述不足，本发明目的提供一种抗拖拉、弯曲、碾压和防腐蚀防水浸湿以及阻燃等性能的充电桩电缆。此电缆的特性以适应充电场所的工作环境，而且具备在拖拉、弯曲、碾压和防腐蚀防水浸湿以及阻燃等情况下电缆能够正常工作，是一种优异的充电桩用电缆。
本发明的方案如下：新能源汽车充电桩电缆, 包括控制线芯和动力线芯，其特征在于，
控制线芯导体外挤包绝缘层构成控制绝缘线芯，三根绝缘线芯绞合后依次设置阻水带绕包层、屏蔽层、控制缆芯护套构成控制线芯；
动力线芯导体外依次设置绝缘层、动力线芯隔离层、动力线芯屏蔽层构成动力线芯；
一根控制线芯和两根动力线芯绞合后由内向外依次设置阻水绕包层、内护套、纤维编织加强层、外护套。控制绝缘线芯与阻水带绕包层之间，控制线芯、动力线芯与阻水绕包层之间，均填充阻水膨胀膏。
进一步，所述的导体为六类镀锡圆铜线导体，采用多股镀锡圆铜线股绞和复绞。
进一步，所述的绝缘层是以三元乙丙胶为基料的橡皮制成。
进一步，所述的内、外护套是以三元乙丙胶为基料的低烟无卤、阻燃、耐磨、耐腐蚀、耐油橡皮材料制成。
进一步，所述的外护套表面贴覆反光膜/荧光膜
电缆的控制线芯导体和动力线芯导体的性能符合GB/T3956-2008国标中第6种的镀锡软铜导体，采用多股细铜线股绞和复绞，并且为股绞和复绞同向的结构形式，这样就提高了电缆的柔软性。
本发明的绝缘是以三元乙丙胶为基料的橡皮，电气绝缘性能好，绝缘电阻由原来的1014Ω·cm提高到现在的1016Ω·cm，介电强度由原来的18kV/㎜提高到现在的30kV/㎜，电气性能良好。
本发明内、外护套是以三元乙丙胶为基料的低烟无卤、阻燃、耐磨、耐腐蚀、耐油橡皮材料制成，所以机械强度由原来的11Mpa提高到现在的19Mpa，伸长率由原来的150%提高到现在的450%，抗撕强度由原来的5N/㎜（裤型直角法）提高到现在的8N/㎜，耐磨性能也有很大的提高；在燃烧时没有有害气体放出，透光率由原来的60%提高到现在的70%以上；电缆经酸、碱腐蚀性能试验后，产品没有受到任何损伤，浸油后抗张强度变化率由原来的最大－50%、提高到现在的－30%，浸油后断裂伸长率由原来的最大－50%、提高到现在的－30%，内外护套之间在增加了芳纶丝编织加强层大大提高了电缆的机械性能。
本发明有良好的电性能、抗干扰性能和阻水性能，以及低烟无卤阻燃、耐磨、耐油、耐腐蚀等性能特别适于在新能源汽车充电桩使用的专用电缆。
本发明电缆在外护套外表面设置有若干凸出部，在实际中，该凸出部首先与外部接触摩擦，等到该凸出摩擦平整后才接触到缆身，这种设计，可增加外护套的摩擦寿命。本发明外护套外贴覆反光膜/荧光膜，在黑夜检修时，可首先发现电缆，提高检修效率。
附图说明
图1为本发明的结构示意图。
具体实施方式
下面结合附图对本发明做进一步说明。

尽管上文对本发明的具体实施方式给予了详细描述和说明，但是应该指明的是，我们可以依据本发明的构想对上述实施方式进行各种等效改变和修改，其所产生的功能作用仍未超出说明书所涵盖的精神时，均应在本发明的保护范围之内。
