40Kn U40B Disc Glass Electrical Insulators with High Dielectric Strength

U40B Disc Glass Electrical Insulators are designed to withstand high voltages without allowing electricity to pass through them. They are essential for preventing electrical faults in overhead transmission lines. U40B glass insulator have a mechanical strength of 40 kN, meaning it can withstand a tensile load of 40,000 newtons.

U40B Disc Glass Electrical Insulators are typically used in overhead power lines for electrical insulation and mechanical support of conductors. These insulators are part of the suspension insulator family and are commonly referred to as "disc insulators" because of their shape. They are made of tempered glass, which provides excellent mechanical and electrical performance. U40B Disc insulators are often used in strings, where multiple discs are connected in series to achieve the desired voltage insulation level. The number of discs in a string depends on the line voltage. Nooa Electric's U40B disc glass insulator is a cap and pin type toughened glass insulator designed for high-voltage applications, offering a mechanical failing load of 40 kN and rated for voltages up to 75 kV.Its robust construction, combined with good electrical performance and cost-effectiveness, makes it a popular choice for overhead transmission and distribution lines in clean to mildly polluted environments

1. Made from tempered (toughened) glass, which is highly durable and resistant to mechanical stress, thermal variations, and electrical stress.
2. Tempered glass offers excellent durability, resistance to environmental conditions, and long service life. It is less prone to aging compared to other materials like porcelain.
3. These glass insulators have a disc-like shape, with each disc designed to support and insulate a section of the conductor.
4. U40B disc insulators are commonly used in overhead high-voltage transmission lines to suspend and insulate the conductors from the towers or poles.
