Extremely adaptable: The U70C (XP-70C) adopts a standard ball socket connection structure, fully conforming to the general standards of the power industry. It can seamlessly match various hardware components of high-voltage transmission lines, and the installation and disassembly operations are simple. It is compatible with the existing line construction process.
Made of high-alumina ceramic material, with stable mechanical performance: The high-purity alumina ceramic material is fired at high temperatures, resulting in a high density and hard texture of the ceramic body. The mechanical failure load is stable at 70kN, capable of withstanding mechanical loads such as conductor tension and wind force impact. The insulation resistance is high and the dielectric loss is small. The performance does not show significant degradation throughout the operation cycle and is not prone to cracking or damage.
Low operation and maintenance costs, wide grid adaptability: Strong operational stability. Daily inspections only require manual visual checks to quickly identify defects. There is no need for frequent live-line detection. After a fault, the remaining mechanical strength can prevent the insulator string from breaking off, reducing the frequency of line emergency repairs, and meeting the operation requirements of different levels of grids, thereby reducing long-term operation costs.

10kV and above overhead transmission lines for AC power: As core insulating components, they are applied to 10kV to 220kV overhead transmission lines to achieve insulation isolation and mechanical fixation between conductors and towers as well as the earth, capable of withstanding the mechanical tension and high-voltage electric field impact during normal operation of the lines.
Insulation of substation busbars and electrical equipment: Suitable for the insulation and fixation of busbars in various substations and external live conductors of outdoor electrical equipment, able to withstand the complex electric field environment within the substation, effectively isolating different potential conductors and preventing leakage and short-circuiting problems.
Rural power grid upgrading projects lines: Widely used in high-voltage transmission lines in rural power grid upgrading projects, adapted to the erection environment of multiple hills and farmlands in rural areas.
High-voltage distribution lines in urban-rural fringe areas: Applicable to high-voltage distribution lines in the urban-rural fringe areas.
