250kV ANSI C29.1 Solid Core Station Post Insulator For Substation


Substation high voltage soild-core station post insulator TR-214 / light gray





1. Hardwares our insulators have externally attached caps or bases. a highly engineered cementing

system transfers the load uniformly from the hardware into the

porcelain body .

2. Porcelain body Each insulator body is made from the highest quality clay raw materials that have been processed to be fully vitrified porcelain . the body is glazed to add strength improve surface appearance, and enhance clean-ability.

3. Electrostatic rain deflector the wet flashover characteristics of the taller station post stacks are improved by placing metal rain deflectors between each of the sections. the deflectors use the electrostatic field surrounding the insulator to disperse falling rain water and prevent flooding of the lower sections.





1. Glaze: Light Gray
2. Creepage distance: 1092mm
3. Impulse withstand voltage: 250kV
    Impulse flashover voltage: 280kV
4. Wet power frequency withstand voltage: 100kV
5. Cantilever strength: 8.9kN Torsion strength: 1360N.m

    Compression strength: 66.8KN Tension strength: 62.3KN
6. Standard: ANSI C29.9 C29.1





Solid core station post insulator used for substations and electrical switch etc. The insulator can be used as vertical or inverted.
