Features
1. The post insulator we provide ranges from 10kV to 220kV.
2. Mainly designed for substation use, this post type insulator boasts excellent hydrophobicity as well as high ageing and corrosion resistance.
3. Adaptive to urban narrow corridor area, the post insulator enables voltage increase and power distribution, fitted for LAN (local area network) technical reform. Meanwhile, by using this post type composite insulator, you won’t be bothered with undue tower height, thus a mass of manpower and material resources are saved.
4. Thanks to high bending strength, breakage hazard is avoided.
5. With one-piece rod-type profile, compact structure and high quality, our post insulator is also featured by lightweight design, and its weight is only 1/10 of porcelain or glass insulator of same grade. Therefore, transportation is extremely convenient.
