Glass insulator U40 triple type

U40 triple type glass insulator is a compact and high-performance standard composite suspension insulator string designed specifically for medium and low voltage transmission lines. It assembles three tempered glass insulators with a rated mechanical and electrical failure load of 40kN into a stable integrated unit through mature and excellent metal connectors, providing standardized insulation support solutions for straight or small angle towers of the line.

Core design philosophy and characteristics

Standardization and Convenience: As a pre assembled "triad", it greatly simplifies the process of circuit design, material procurement, and on-site installation. Construction personnel do not need to perform single piece assembly and tedious tension calculation on site, and can directly install it as a whole unit, significantly improving construction efficiency and reducing errors that may arise from on-site assembly.

Mature and excellent basic unit: Its core is composed of U40 standard tempered glass insulators that have been verified through long-term engineering. Each insulator has excellent electrical performance and the reliable advantage of "zero self explosion" - that is, when the insulator loses its insulation performance due to lightning strikes, internal defects, or other reasons, the tempered glass umbrella skirt will be completely broken and detached. Operation and maintenance personnel do not need to climb the tower, and can clearly detect the fault point from a distance through a telescope, greatly improving the efficiency and safety of line inspections.

Excellent comprehensive performance: Tempered glass material itself does not age or deteriorate, and its electrical strength remains stable throughout its entire life cycle. Smooth surface with good self-cleaning properties. Although designed as a standard type, its creepage distance and electrical performance are sufficient to meet operational requirements in general clean areas.

Economy and applicability: U40, as a medium mechanical strength insulator, combined with the structure of a triple body, provides a cost-effective and reliable standardized configuration solution for specific voltage levels (such as suspension strings for 35kV lines). Its mechanical strength is sufficient to withstand the conventional load of the corresponding wire.

Mainly suitable for the following situations:

Suspension insulator strings for straight towers of overhead transmission lines with voltage levels of 35kV and below.

Tensioning towers or terminal towers with smaller line turning angles.

New construction or renovation projects of distribution lines that require high construction efficiency and pursue standardized operations.

Lines in general rural and suburban areas with clean air and low pollution levels.

Advantages of choosing U40 triple type insulator

Choosing this product means you have obtained a ready to use, stable and excellent insulation solution:

Faster installation: reduces on-site operation time and labor costs.

Easy operation and maintenance: Thanks to the "zero value self explosion" characteristic of glass insulators, fault identification is intuitive and maintenance difficulty is reduced.

Stable quality: Factory pre assembly ensures consistency and optimal connection.

Economical and practical: In applicable scenarios, excellent insulation and mechanical support functions have been achieved at a reasonable cost.
