FAQ

 

PRODUCT CHATACTERISTICS
1. What are the advantages of glass insulators?
Glass insulator has zero value self-explosion characteristics, when the insulator deteriorates and loses insulation performance, it will automatically break, which is convenient for operation and maintenance personnel to find and replace in time to ensure the safety of the line. Its mechanical strength is high, can withstand large tensile force, pressure and bending moment and other mechanical loads, adapt to different line conditions. The surface is smooth, not easy to accumulate pollution, compared with other insulator types in the same environment, the pollution lightning voltage is higher, has good anti-pollution performance, and excellent aging resistance, can maintain stable insulation and mechanical properties in long-term operation, long service life, usually up to 30-40 years or even longer.

2. What are its disadvantages?
Glass insulators are relatively heavy and may require more human and material resources during transportation and installation. Its production process is more complex, high requirements for raw materials and manufacturing technology, resulting in the cost may be slightly higher than some other insulators. And once the self-explosion, the glass fragments may fall, there is a certain safety risk to the people and objects below, but now there are also some anti-debris design and measures are gradually applied.

INSTALLATION AND MAINTENANCE
1. What should I pay attention to during installation?
Before installation, check the appearance of the glass insulator to ensure that there are no cracks, damage or other defects. Handle with caution during installation to avoid damage caused by collision. Install the fittings correctly according to the design requirements to ensure the connection is firm and reliable, and strictly control the tilt Angle and tension of the insulator string during installation to ensure uniform force.

2. How to perform routine maintenance?
Perform regular inspection to check for self-detonation, flashover traces, or other anomalies. For dirty areas, timely cleaning can be arranged according to the degree of pollution, generally using water flushing or special electric cleaning equipment. The temperature distribution of insulators is detected by infrared temperature measurement and other technical means to determine whether there is abnormal heating phenomenon such as local overheating. If deterioration or damage is found, it should be recorded in time and arranged for replacement.

TECHNICAL PARAMETERS
1. What are the main technical parameters?
It mainly includes the rated voltage, which determines the voltage level of the power system applicable to the insulator; Mechanical failure load, which represents the maximum mechanical force that the insulator can withstand; Creepage distance affects the anti-fouling performance of insulators. The longer the creepage distance, the stronger the anti-fouling ability; There are also parameters such as insulation resistance and capacitance value, which reflect the insulation performance and electrical characteristics of the insulator. Lines with different voltage levels and application scenarios have different requirements for these technical parameters of glass insulators.

2. How to select the glass insulator with appropriate parameters according to the line requirements?
First, the rated voltage of the insulator is determined according to the voltage level of the line to ensure that it can meet the insulation requirements of the system. According to the mechanical load of the line, such as wire self-weight, tension, wind load, ice load, etc., choose the insulator with the appropriate mechanical damage load, and generally leave a margin. Considering the pollution degree of the environment where the line is located, choose products with sufficient creepage distance. For example, in heavily polluted areas, anti-pollution glass insulators with long creepage distance should be selected, and other relevant parameters should be comprehensively determined in combination with local climate conditions to ensure that the insulator can operate stably on the line for a long time.
