Description

电缆护套
技术领域
本发明涉及高分子塑料技术领域，尤其是一种电缆护套。
背景技术
35KV及以下的高压电缆由缆芯和护套构成，目前护套主要由PVC材料制成，PVC材料护套在环境温度偏高时，会有比较大的收缩；设计如下实验对PVC材料护套的热缩率进行验证：取原长为35.2厘米的PVC材料的护套进行高温老化，老化条件为：温度：140℃，老化时间：4小时，冷却时间：1小时；第一次老化后，护套的长度为：33.2厘米；第二次老化后，护套的长度为：33.1厘米；第三次老化后，护套的长度为：33.0厘米；第四次老化后，护套的长度为：33.1厘米；第五次老化，护套的长度为：33.0厘米；根据实验表明，PVC材料护套的热缩率为6.3%，超过了国家标准的5%的要求；从而得出，电缆发热及环境的散热条件影响也会电缆护套产生热缩率，护套热缩越大，护套将越容易与缆芯脱离，从而对电缆的保护越差。
发明内容
本发明所要解决的技术问题是提供一种电缆护套，它可以解决护套热缩大的问题。
为了解决上述问题，本发明所采用的技术方案是：这种电缆护套，包括以下重量份的原料制成：交联聚乙烯50-70份，增塑剂5-9份，无铅稳定剂6-10份，抗氧化剂12-15份，共混改进剂8-12份，玻璃纤维20-25份，聚醚醚酮15-25份；聚醚砜10-15份，碳纤维8-15份。
上述技术方案中，更具体的技术方案还可以是：共混改进剂是丁腈橡胶。
由于采用了上述技术方案，本发明与现有技术相比具有如下有益效果：
在原材料中加入玻璃纤维、聚醚醚酮、聚醚砜和碳纤维可以增强护套的耐热性能、降低护套的热缩率和提高护套性能稳定性。
具体实施方式
以下结合具体实施例对本发明作进一步详述：
实施例1：
这种电缆护套，包括以下重量份的原料制成：交联聚乙烯50份，增塑剂5份，无铅稳定剂6份，抗氧化剂12份，共混改进剂8份，玻璃纤维20份，聚醚醚酮15份；聚醚砜10份，碳纤维8份，其中共混改进剂是丁腈橡胶。
实施例2：
这种电缆护套，包括以下重量份的原料制成：包括以下重量份的原料制成：交联聚乙烯60份，增塑剂7份，无铅稳定剂8份，抗氧化剂14份，共混改进剂10份，玻璃纤维23份，聚醚醚酮20份；聚醚砜12份，碳纤维11份，其中共混改进剂是丁腈橡胶。
实施例3：
这种电缆护套，包括以下重量份的原料制成：交联聚乙烯70份，增塑剂9份，无铅稳定剂10份，抗氧化剂15份，共混改进剂12份，玻璃纤维25份，聚醚醚酮25份；聚醚砜15份，碳纤维15份，其中共混改进剂是丁腈橡胶。
以上重量份的原料制成的电缆护套，取出长度为35厘米进行高温老化实验，老化条件为：温度：140℃，老化时间：4小时，冷却时间：1小时；第一次老化后，护套的长度为：35.1厘米；
第二次老化后，护套的长度为：35.0厘米；
第三次老化后，护套的长度为：35.05厘米；
第四次老化后，护套的长度为：35.0厘米；
第五次老化，护套的长度为：35.02厘米；
经过该实验后，本发明的电缆护套的热缩率为0.06%。
