The significance of measuring the insulation thickness of wires and cables from freeamfva's blog

1.Standard value: The insulation thickness specified in the wire and cable product standard is based on the applicable voltage level of the product, the size of the conductor cross-section, the size of the current carrying capacity, the environmental conditions used, the electrical properties of the insulation material, the physical and mechanical properties, and the long-term consideration Many factors of the service life are determined through scientific calculations and long-term practical experience.

The significance of the measurement: if the measured value is smaller than the specified value, the wire and cable product will lose electrical insulation until it is broken down, causing personal and property damage; if it is greater than the specified value to a certain extent (exceeding the maximum value of the wire) Path), which brings a lot of troubles to users, until they can not be used, and increases costs for production
