What are the special requirements for the installation and maintenance of composite high-voltage insulators?

Inspection before installation:
Before installation, it is necessary to conduct a comprehensive inspection of the composite high-voltage insulator to ensure that there are no cracks, defects or dirt on its appearance, and to confirm that the connections of each component are tight and there is no looseness.
Check whether the porcelain part of the insulator has cracks, glaze peeling or burn marks, as these may affect its insulation performance.

Choice of installation location:
Insulators should be installed in a suitable location to avoid being affected by mechanical stress, environmental pollution or other adverse factors. For example, it should be avoided to install in an environment with large vibration, drastic temperature changes or severe chemical corrosion.
At the same time, it is necessary to ensure that the distance between the insulator and the surrounding equipment meets safety regulations to prevent discharge or short circuit.

Precautions during installation:
During the installation process, it should be carried out strictly in accordance with the construction drawings and operating procedures to ensure that the insulator is installed firmly and stably, and the connection with the conductor, hardware and other components is reliable.
During installation, special attention should be paid to avoid damaging the porcelain part of the insulator to prevent cracks or breakage during installation.

Maintenance during operation:
Periodically inspect the composite high-voltage insulator to observe whether there are abnormal conditions such as dirt accumulation, crack expansion or discharge marks on its surface.
Problems found should be dealt with in a timely manner. For example, severely contaminated insulators should be cleaned; insulators with extended cracks should be replaced in a timely manner.
During thunderstorm seasons or in severe weather conditions, monitoring of insulators should be strengthened to prevent accidents such as lightning strikes or flashovers.

Personnel training and safety awareness:
Provide professional training for personnel responsible for insulator installation and maintenance to improve their operating skills and safety awareness.
Emphasize the importance of safe operating procedures, ensure strict compliance with safety regulations during operations, and prevent personal injury and equipment damage accidents.
