What material is the mandrel
2024/04/24
The core rod is a material used for composite insulators, which is mainly composed of a glass fiber body and a resin, and is formed by heating and curing through a mold. The material of the mandrel has a great influence on the acid corrosion resistance of the product, so it is necessary to make a reasonable choice according to the material characteristics of the mandrel. In addition, the pultrusion process of the mandrel also needs to be optimized to improve the overall electromechanical properties of the mandrel.
The mandrel in the household water dispenser also needs to be replaced regularly, generally 3-6 times a year. The cleaning method of the water dispenser includes unplugging the power plug, removing the bucket, opening the sewage pipe outlet, draining the residual water, turning on the hot and cold water switch to drain the water, removing the "smart seat", scrubbing the inner container and the inner and outer sides of the lid with alcohol cotton, and disinfecting with decontamination effervescent tablets or special disinfectants.
Silicone rubber skirt is also a common mandrel material, which has the characteristics of uniform material, compact and complete internal structure, no bubble gap, high internal insulation performance, etc., which can improve the safe operation of transmission lines. Umbrella skirt also has excellent electrical corrosion resistance, trace resistance, anti-oxygen, anti-ozone and anti-aging properties.
