Description

technical field [0001] The invention relates to an insulating impregnating potting wax, which is especially suitable for insulating impregnating potting of electronic transformers, high-frequency transformers, inductance coils and coils of other electronic components. Background technique [0002] In the production of transformers, it is necessary to use insulating impregnated potting wax to carry out insulating impregnated potting on transformers. Simply using commercial paraffin wax or microcrystalline wax, although the price is cheap, has defects such as poor high-temperature performance and toughness and plasticity, and it is easy to lose at working temperature and easy to break under the action of external force. The use of oil is prone to leakage. The use of resin materials has the advantage of good high-temperature performance, but has defects such as poor toughness and plasticity and high cost, which cannot meet the requirements of current production plants. The ex...
