High-voltage bushing vacuum oil filling and insulation oven

Detection standards:

GB/T 2900.10-2013, the national standard "Electrical Terminology - Cables" is by TC232 (National Electrical Terminology Standardization Technical Committee), and this standard is equivalent to the IEC international standard: IEC 60050-461:2008.

GB/T 7354-2018, the national standard "High Voltage Test Technology - Partial Discharge Measurement" is under the jurisdiction of TC163 (National High Voltage Test Technology and Insulation Coordination Standardization Technical Committee), with the competent department being the China Electrical Apparatus Industry Association. This standard is modified and adopted from the IEC international standard: IEC 60270:2000.

GB/T 13032-2008

IEEE 386-2014, this standard specifies the requirements in terms of electrical performance, mechanical performance, and environmental adaptability of high-voltage bushings (including oil-filled, gas-filled, oil-free, and gas-insulated bushings), and is one of the important standards for the performance evaluation of high-voltage bushings.

IEC 60050-363:2011, this standard stipulates the technical requirements, test methods, inspection rules, packaging, transportation, and storage requirements of high-voltage bushings, which is similar to the GB/T 2900.10-2001 standard.
