Core rod is a material used for composite insulators, mainly composed of glass fiber body and resin, which is solidified by mold extrusion and heating. The material of the core rod has a significant impact on the acid and corrosion resistance of the product, so it is necessary to make a reasonable selection based on the material characteristics of the core rod. In addition, the extrusion molding process of the core rod also needs to be optimized to improve the overall electromechanical performance of the core rod.
The core rod in household water dispensers also needs to be replaced regularly, usually 3-6 times a year. The cleaning method of the water dispenser includes unplugging the power plug, removing the water bucket, opening the drain pipe, draining the remaining water, turning on the hot and cold water switch to release water, removing the “smart seat”, scrubbing the inner and outer sides of the inner tank and lid with alcohol foam, and disinfecting with a decontamination effervescent tablet or specialized disinfectant.
Silicone rubber umbrella skirt is also a common core material, which has the characteristics of uniform material, tight and complete internal structure, no bubble gap, high internal insulation performance, etc., and can improve the safe operation of transmission lines. Umbrella skirts also have excellent resistance to electrical corrosion, leakage marks, oxygen, ozone, and aging.
