产品技术优势与特点

· 应力锥采用优质进口液体硅橡胶注胶成型,并采用有限元电场分析优化设计,解决了产品的电场优化问题,以确保产品长期运行的可靠性

· 接头主绝缘为整体预制结构,导体的高压屏蔽与绝缘、绝缘屏蔽预制成为一个整体件,结构紧凑简单,便于安装

· 在铜壳保护盒基础上,最外层采用为玻璃钢保护盒,内浇注高压绝缘防水胶,增加了防腐蚀、防爆、防水以及抗机械力破坏性能

Product technical advantages and features

·The stress cone is molded with high-quality imported liquid silicone rubber and optimized by finite element electric field analysis, which solves the electric field optimization problem of the product and ensures the reliability of long-term operation of the product.

·The main insulation of the joint is an integral prefabricated structure, and the high-voltage shielding, insulation, and insulation shielding of the conductor are prefabricated into an integral part, which is compact and simple in structure and easy to install.

·On the basis of the copper shell protection box, the outermost layer is made of fiberglass protection box, and the inner layer is poured with high-voltage insulation waterproof glue, which increases the corrosion resistance, explosion-proof, waterproof and anti-mechanical damage performance.
