Notes on using insulating rods Before use, it is necessary to check whether the voltage level of the insulating rod is the same as the voltage level of the electrical equipment being operated. When using an insulated rod, staff should wear insulated gloves and insulated boots to enhance the protection of the insulated rod. Insulated poles without umbrella covers should not be used in rainy, snowy or wet weather. When using insulating rods, be careful to prevent collisions to avoid damage to the surface insulation layer. Precautions for installation of composite insulators Composite insulators should be stored in a dry warehouse, and anti-rat measures should be taken. Oil and petrochemical items should be avoided in the storage area. During transportation, metal tools and other heavy objects should not be stacked directly on the insulator to avoid damaging the composite insulator umbrella cover, so the packaging box should be unboxed at the installation site. Be sure to be careful when unboxing and do not let the sharp tools cut the umbrella skirt. At the installation site, for longer composite insulators, do not drag the composite insulators to the ground and walk. For products with 330 kV and above, care should be taken not to excessively bend the composite insulator to avoid excessive bending stress on the mandrel. When manually transporting a very long composite insulator, it should be carried by two or more to avoid sagging in the middle and causing the surface of the umbrella skirt to be scratched, affecting the electrical performance and service life of the composite insulator. When hoisting composite insulators, it is not allowed to hang the rope directly on the umbrella sleeve, but should be hung on the end attachment, that is, the ball socket. When installing the pressure equalization ring, be sure to pay attention: face the ring-shaped smooth surface of the pressure equalization ring towards the composite insulator umbrella skirt. Do not trample or climb composite insulators. Do not step on the installed equalizing ring or hanging rope and heavy objects on the equalizing ring to avoid loosening or damage to the surface. During the installation process, try to avoid excessive bending or torsional stress on the mandrel. At the same time, do not rotate the fixed or loaded composite insulator when hanging the wire. Install the pressure equalization device correctly, be careful to install it in place, and do not install it inverted. And carefully adjust the annular surface to be perpendicular to the composite insulator axis. For the opening-type pressure equalization device, please note that the opening directions of both ends are consistent.
