What is a wire withstand voltage testing machine?
In the power industry and electronic manufacturing fields, the wire withstand voltage testing machine is a vital testing equipment. It is mainly used to test the voltage resistance performance of wires, cables, electrical equipment and their insulation materials to ensure that they can operate safely in high voltage environments. This article will introduce in detail the definition, working principle, application scenarios and popular models of the wire withstand voltage testing machine, and provide you with a comprehensive analysis based on hot topics in the past 10 days.
1. Definition of wire withstand voltage testing machine

The wire withstand voltage testing machine is a special equipment used to test the insulation strength of wires, cables or other electrical equipment. It tests whether the insulating material can withstand high voltage without breakdown or leakage by applying a test voltage higher than the rated voltage. This kind of testing is an important part of ensuring the safety of electrical equipment.
2. Working principle
The working principle of the wire withstand voltage testing machine is to generate high voltage through a high-voltage generator, apply it to the wire or cable under test, and monitor the changes in current at the same time. If the insulation performance is good, the current will remain at a very low level; if there are defects in the insulating material, the current will increase significantly and even breakdown will occur.
| test items | Test voltage range | Test time |
|---|---|---|
| low voltage wire | 500V-3000V | 1-5 minutes |
| medium voltage cable | 3000V-10000V | 5-15 minutes |
| High voltage cable | 10000V or more | 15-30 minutes |
