What is 300kV insulating Cylinder power frequency withstand voltage tester?

 

 The 300kV insulating Cylinder power frequency withstand voltage tester is a power frequency (50/60Hz) high-voltage testing device used for testing the insulation strength of high-voltage equipment. Its key feature is the use of an insulating barrel (insulating cylinder) structure to achieve both high voltage output and good insulation.

300KV01

1. 300kV (Voltage Level)
Indicates the equipment's maximum output voltage can reach 300 kV. Suitable for withstand voltage tests on ultra-high voltage equipment.

 

2. Insulating Cylinder (Structural Form)
Refers to high-voltage components encapsulated within an insulating cylinder/bucket.
Common materials: epoxy resin, composite insulating materials, etc.
Functions:
Improves overall insulation level
Moisture-proof and dust-proof
Compact structure, high safety.

 

3. Power Frequency Withstand Voltage Tester
Output frequency is power frequency (50Hz or 60Hz). Used for withstand voltage tests.
Verifies whether the test object breaks down or flashovers under a specified voltage.

 

II. Typical Applications
Power transformer withstand voltage test
High-voltage cable insulation test
Switchgear, bushing, and insulator testing
Power equipment factory testing and field acceptance testing

 

III. Core Advantages
High voltage level (300kV): Suitable for high-voltage/ultra-high voltage equipment
Compact insulating bucket structure: High safety, small footprint
Strong standardization of power frequency testing: Meets IEC/national standard requirements
Stable and reliable operation: Stable output waveform, reliable test results
