This 25kV/27.5kV Positioning Insulator is crafted for railway electrification applications. Its manufacturing demands meticulous design, specialized production techniques, and reliable quality control.
During its operation, it not only suspends the conductors but also withstands multiple types of loads. It endures tensile loads like a typical Suspension Insulator and additionally bears bending loads caused by the swaying of contact network wires. The need to handle complex torsional loads, arising from various sources such as natural winds, winds generated by high-speed trains, and train-induced vibrations, sets it apart. To meet these mechanical challenges, it features a thicker core rod compared to regular Suspension Insulators, enhancing its overall mechanical performance. In essence, it combines characteristics of both Suspension and Post Insulators, similar to Anti - Windage Yaw Insulators used in power grids, making it highly adaptable to the specific demands of the railway environment.
Standards:
IEC 62621-2011; TB/T 3199.2-2018; Q/CR 549-2016
Specifications:
Since the Positioning Insulator is a special series product of the Suspension Insulator, it should first meet the basic requirements of the Suspension Insulator series. More specific parameter requirements should rely on in-depth communication between the two trading parties.
This product has a relatively high degree of customization, and JD Electric has a high-level technical team for its design.
Application:
It is mainly utilized for precisely positioning and supporting conductors in the electrified railway network. Its primary role is to maintain stable electrical insulation and reliable mechanical support, which is essential for the uninterrupted power supply and the safety of the railway electrification system.
