Basic characteristics of glass insulators
Materials and Structure: Glass insulators typically consist of a steel cap, tempered glass, and a steel base, bonded together with cement. Tempered glass has high load-bearing capacity, safety, reliability, temperature resistance, and impact resistance, and is a widely used prestressed glass.
Performance characteristics of glass insulators
High mechanical strength: The surface of glass insulators has high mechanical strength, making them less prone to cracking and slower to age. Convenient self-explosion detection: It has the self-elimination ability of "zero self-explosion", no need to climb poles to detect one by one, it can be observed on the ground or helicopter, reducing the labor intensity of workers. The annual self-damage rate of products put into the production line is 0.02%-0.04%, which can save line maintenance costs.
The main advantages of glass insulators
Large main capacitance and uniform voltage distribution: The dielectric constant of glass is 7 - 8, which gives tempered glass insulators a large main capacitance and uniform voltage distribution in the string. This helps to reduce the voltage borne by insulators near the conductor side and the ground side, reduce radio interference, lower corona loss, and extend the life of glass insulators.
