Pre-fabricated dry termination is integrally composited of stress cone and silicone rubber insulation material. Stress cone is made of conductive silicon rubber, which is designed and computing optimized by finite element analysis software. It has reliably improved and balaced the electric field distribution at the cable shield fracture section.
Product characteristics
1.Injection-molded from high quality imported silicone rubber with high strength and elasticity and aging resistance, so it has good corrosion resistance, anti electrical erosion ability and hydrophobic property as well as excellent anti pollution flashover performance, still keeping good electrical properties under severely polluted condition.
2. Seamless manufacturing process, improves products mechanical and physical performance and electrical properties.
3. Light weight, about 1/8 - 1 / 1 0 weight of outdoor termination with porcelain insulator and less components, so it is easy to install.
4. Full silicone rubber dry type structure, no need for oil filled and gas, so it is no pollution to the environment.
5. Flexibility shakeproof, no fire and explosion risk and free maintenance for operating.
6. Unbreakable, so it is convenient for transportation and installation.
7. Flexible installation position and direction, so it can be installed on the pillar or overhead line tower vertically or inclinedly.
8. Each termination kit will be 100% inspected according to the standard in the factory.
