The LXY Series U160BL Glass Insulator is a high-strength toughened glass suspension insulator designed for high-voltage overhead transmission lines. This U160BL glass insulator provides excellent mechanical strength and stable electrical insulation performance, making it suitable for long-span transmission lines and heavy conductor loads. Its transparent glass structure allows easy visual inspection, helping utilities quickly identify damage and maintain system reliability.
(1) Compared with porcelain, it has a very high dielectric strength;
(2) High electrical resistivity;
(3) Compared with porcelain insulators, it has higher tensile strength;
(4) Due to its transparent nature, it will not be heated in sunlight like porcelain;
(5) The impurities and bubbles inside the glass insulator body are easily detected due to their transparency;
(6) The service life of glass is very long because its mechanical and electrical properties are not affected by aging;
(7) Glass is cheaper than porcelain.
