Stainless Steel Electrical Resistivity Test Equipment For Solid Insulation Materials

IEC60243 Electrical Strength Testing Equipment / Test Apparatus For Solid Insulation Materials

1. Description

The tester is suitable for testing breakdown strength and voltage withstanding time of solid insulating materials such as plastics, film, resin, mica, ceramics, glass and insulating paint under power frequency voltage.

2. Standards

GB1408.1, IEC60243-1, GB/T1695-2005, GB/T3333 GB12656 and ASTM D149

It conforms to GB1408.1, IEC60243-1 "Electrical Strength Test Method for Solid Insulating Material - Test at Power Frequency", GB/T1695-2005 "Measurement Method for Power Frequency Breakdown Voltage Strength and Voltage Resistance of Vulcanized Rubber" GB/T3333 GB12656 and ASTM D149 test standards.

3. Scope of Application

Suitable for continuous and uniform boosting or step-by-step boosting, apply alternating current voltage to the sample until breakdown, measure the breakdown voltage value and calculate the breakdown strength of the sample. Use the method of rapid boosting, raise the voltage to the specified value, keep the sample from breakdown for a certain period of time, and set the specified value as the voltage resistance value of the sample.

4. Terms and Definitions

(1) Voltage withstand value: quickly raise the voltage to the specified value, keep the sample not broken down for a certain time, call this voltage value of the sample withstand voltage value, expressed in KV.

(2) Breakdown voltage: The sample is broken down under a certain voltage. At this time, the value of the voltage is called breakdown voltage, which is expressed in terms of KV.

(3) Breakdown voltage strength: The ratio of the breakdown voltage of the sample to its thickness is called voltage strength, which is expressed in KV/mm.
