This article presents a comprehensive verification test conducted to assess the insulation capabilities of PVC hoses used in power equipment manufacturing. The test aims to evaluate the suitability and reliability of PVC hoses for insulation purposes.

Test Setup and Procedure

The test was carried out in a controlled laboratory environment. Different samples of PVC hoses were selected from various manufacturers and subjected to rigorous testing methods. The test procedure involved the following steps:

1. Visual Inspection: The PVC hoses were visually inspected for any physical defects or irregularities.
2. High Voltage Test: The hoses were subjected to a high voltage test to determine their breakdown voltage and to ensure they can withstand the expected operating voltage.
3. Resistance Test: The electrical resistance of the hoses was measured to evaluate their insulation capabilities.
4. Environmental Testing: The hoses were exposed to various environmental conditions, including extreme temperatures and humidity, to assess their resistance to degradation.
5. Bend and Flexibility Test: The hoses were bent and flexed repeatedly to determine their durability and resistance to wear and tear.

Test Results and Analysis

The verification test yielded the following outcomes:

• Breakdown Voltage: The PVC hoses exhibited a consistently high breakdown voltage, indicating their ability to withstand electrical stress and prevent voltage leaks.
• Electrical Resistance: The tested hoses demonstrated excellent electrical insulation properties with minimal electrical leakage.
• Environmental Resistance: The hoses displayed remarkable resistance to environmental factors, such as temperature variations and humidity, ensuring prolonged insulation performance.
• Bend and Flexibility: The hoses showed exceptional flexibility and durability, with no signs of material degradation or deformation after repeated bending.

Overall, the test results suggest that the PVC hoses used in power equipment manufacturing met the required insulation standards and exhibited excellent insulation performance.

Conclusion
