交联聚乙烯绝缘电力电缆用液体填充绝缘瓷套管户外终端

主要应用于高压交流输电领域，高压电力电缆与电气设备或架空线的连接,66kV、110kV、138kV、220kV交联聚乙烯绝缘电力电缆用液体填充绝缘瓷套管户外终端。

终端应力锥采用进口三元乙丙橡胶（EPDM）注射成型，由弹簧锥托顶紧，且采用应力锥罩结构将应力锥和绝缘填充剂隔离，克服了应力锥由材料老化带来的弹性松弛、应力锥与电缆外半导电层接触不良等弊病，以确保终端长期安装稳定运行；
终端采用多层密封结构，以防止终端在运行过程中出现渗水、漏油等现象；
终端套管采用大小伞裙结构，具有良好的防污闪特性；
瓷套采用高强度无机材料制成，具有良好的耐气候性、抗漏痕、电蚀能力和憎水性能。

Product name: Liquid-filled insulating porcelain bushing outdoor termination for XLPE insulated power cables. Application field: Mainly used in high-voltage AC transmission, for connecting high-voltage power cables to electrical equipment or overhead lines, as outdoor terminations with liquid-filled insulating porcelain bushings for 66kV, 110kV, 138kV, and 220kV XLPE insulated power cables. Product description: The stress cone is injection-molded from imported EPDM rubber, pressed tightly by a spring cone support, and a stress cone cover is used to isolate the stress cone from the insulating filling compound, overcoming problems such as elastic relaxation of the stress cone due to material aging and poor contact between the stress cone and the cable's outer semiconductive layer, ensuring long-term stable operation of the termination. The termination adopts a multi-layer sealing structure to prevent water seepage, oil leakage, and other issues during operation. The bushing uses a large-and-small shed design, providing good anti-pollution flashover performance. The porcelain bushing is made of high-strength inorganic material, offering excellent weatherability, tracking resistance, electrical erosion resistance, and hydrophobicity.
