Description
技术领域 technical field
本实用新型涉及一种应用于较高温度区域的电力传输的新型阻燃耐高温电缆，属于电缆技术领域。The utility model relates to a novel flame-retardant and high-temperature-resistant cable used in power transmission in a relatively high-temperature region, which belongs to the technical field of cables.
背景技术 Background technique
由于现代电厂、冶金、矿山、水泥建材等行业的发展，其很多区域均处于90～110℃的较高环境温度情况下，对于使用在该区域的电缆，其由于在传输电流过程中自身也产生热量，导致电缆的导体温度更高可达到130℃左右。普通聚氯乙烯绝缘电力电缆，可允许导体最高运行温度为70℃；交联聚乙烯绝缘电力电缆，可允许导体最高运行温度为90℃，以上两种电缆均无法满足上述使用环境。使用氟塑料或硅橡胶绝缘的电缆，其耐温性能可达到上述环境条件下的使用要求，但由于硅橡胶的机械性能很差，极易磨损、抗撕裂性能差，对电缆的影响较大，导致电缆的性能不够稳定，而且氟塑料和硅橡胶的价格都很高，电缆的生产成本较大。Due to the development of modern power plants, metallurgy, mines, cement building materials and other industries, many areas are in the high ambient temperature of 90-110 ° C, for the cables used in this area, it is also generated during the transmission of current. Heat, causing the conductor temperature of the cable to be higher up to about 130°C. Ordinary PVC insulated power cables allow conductors to operate at a maximum temperature of 70°C; cross-linked polyethylene insulated power cables allow conductors to operate at a maximum temperature of 90°C. Neither of the above two types of cables can meet the above operating conditions. Cables insulated with fluoroplastics or silicone rubber can meet the requirements for temperature resistance under the above environmental conditions. However, due to the poor mechanical properties of silicone rubber, they are easy to wear and have poor tear resistance, which has a greater impact on cables. , the performance of the cable is not stable enough, and the prices of fluoroplastics and silicone rubber are very high, and the production cost of the cable is relatively high.
对于此种环境条件下的耐高温电缆，现在的通常解决方案是采用阻燃型的耐火电缆代替耐高温电缆或使用氟塑料或硅橡胶绝缘PVC护套的电缆，如中国专利94221521、92223066、00216500等公开的耐高温电缆，其均是使用在导体上包裹耐火云母层，再挤包内绝缘、外护层结构，这些电缆由于大量使用了耐火云母，其成本较高，且由于电缆的护层材料的使用温度还是较低，无法达到使用要求。已公开的中国专利03221540耐高温电缆，其使用氟塑料或硅橡胶绝缘，外加玻璃纤维带做隔热层，再以普通PVC做电缆外护套，此结构的耐高温电缆，由于使用了价格昂贵的氟塑料或硅橡胶材料，电缆成本仍很高，而且PVC电缆护套使用温度也还是较低，只能达到70℃，也不太能满足较高温度条件下的使用。For high-temperature-resistant cables under such environmental conditions, the usual solution now is to use flame-retardant fire-resistant cables instead of high-temperature-resistant cables or cables with PVC sheaths insulated by fluoroplastics or silicone rubber, such as Chinese patents 94221521, 92223066, 00216500 The high-temperature-resistant cables disclosed by others are all used to wrap the refractory mica layer on the conductor, and then extrude the inner insulation and outer sheath structure. These cables have a high cost due to the large amount of refractory mica used, and because the sheath of the cable The service temperature of the material is still low and cannot meet the service requirements. The published Chinese patent 03221540 high temperature resistant cable uses fluorine plastic or silicon rubber insulation, adds glass fiber tape as a heat insulation layer, and then uses ordinary PVC as the cable outer sheath. The high temperature resistant cable of this structure is expensive due to the use of The cost of the cable is still high due to the fluoroplastic or silicone rubber material, and the use temperature of the PVC cable sheath is still low, only up to 70°C, and it is not suitable for use under higher temperature conditions.
