U70BS (U70BL) is a standard disc-shaped suspension tempered glass insulator widely used in 10kV to 330kV high-voltage and higher voltage AC/DC transmission lines, responsible for the core functions of insulation and suspension of conductors. It is made of tempered glass as the substrate, combined with metal accessories (iron caps, steel feet) and cement adhesive to form structurally stable and high-performance electrical equipment.
Product advantages
Zero value self breaking characteristic
Tempered glass insulators will self destruct when aged or overloaded, forming obvious signs of breakage, which is easy to detect on the ground or by helicopter inspection. There is no need to climb the pole and inspect each piece, reducing maintenance costs.
After self explosion, the residual section still has mechanical strength to prevent line disconnection accidents.
Good anti pollution flash ability
The surface is smooth and not prone to dirt accumulation. Its wet withstand voltage and dirt withstand voltage are much higher than ceramic insulators, making it suitable for heavily polluted areas such as chemical, coastal, and industrial intensive areas.
Aging and corrosion resistance (based on actual reports)
Glass material has no fixed melting point, stable dielectric properties, slow aging process, and a service life of over 20 years.
Resistant to electric arc sickness, the surface remains smooth even after lightning impact, and the mechanical strength does not weaken.
Lightweight and easy to install
The weight is only 1/6-1/9 of porcelain insulators of the same voltage level, which is convenient for transportation and installation and reduces labor intensity.
Transparency facilitates the detection of internal defects such as cracks and bubbles, improving operational efficiency.
Strong environmental adaptability
Applicable temperature range: -40 ℃ to+50 ℃, low temperature resistance, corrosion resistance (based on actual reports), suitable for extreme weather conditions.
4、 Application scenarios
High voltage transmission lines: 10kV-330kV AC/DC lines, especially suitable for areas with high pollution levels.
Heavy industrial areas/coastal regions: scenes with high demand for corrosion and anti pollution flashover.
Live working line: Zero value self breaking characteristic reduces power outage detection frequency and improves power supply efficiency.
