1. Dimension drawing dimension "B" must be immersed in oil without burning the damaged components. The heated oil shall be free from corrosion.
2. The working level of sry3 type must be under the fastener and above the dimension line "B".
3. When melting solid oil such as asphalt and paraffin, the voltage shall be reduced and then increased to rated voltage after melting. To prevent the concentration of electricity to reduce the service life of the components.
4. When carbon deposit is found on the surface of the pipe, it must be used after the end of the pipe, so as to avoid reducing efficiency and even burning the components.
5. The components shall be stored outside the drying. If the insulation resistance is lower than 1 megohm due to long-term placement, the insulation resistance can be dried in an oven at about 200 ℃ for several hours (or the low voltage of the element passes for several hours), i.e. the insulation resistance can be restored.
