Maintenance Method Of Integrated Sealed Pole

During the operation and maintenance period, Embedded Pole needs to be regularly inspected by infrared thermal imaging. When the abnormal temperature rise exceeds 10K, the poor contact should be checked immediately. Use anhydrous ethanol to clean the surface. It is strictly forbidden to use chlorinated solvents. The dielectric loss factor test is carried out every three years. If the tan8 value increases by more than 50% of the initial value, it needs to be replaced. When troubleshooting, a special disassembly tool is required to apply an axial tensile force of ≥5kN to avoid shear damage to the insulation layer. The storage environment should maintain a relative humidity of ≤60% to avoid contact with organic solvent vapor. The continuous optimization direction of this technology includes nanofiller modified insulation materials (such as adding 2% boron nitride to increase the thermal conductivity to 0.8W/m·K), 3D printing precision molding process (dimensional accuracy ±0.02mm), and intelligent monitoring module integration (built-in RFID temperature sensor). With the improvement of environmental protection requirements, the application proportion of bio-based epoxy resin (castor oil derivative content ≥40%) has increased year by year, while maintaining dielectric properties, reducing the carbon footprint by more than 35%.
