Urgent question: Is it necessary to conduct an insulation resistance test before laying power cables?
Thread Content
As the title says. Is it necessary to measure the insulation resistance of new power cables before laying them? If measurement is required, is there any regulatory basis to support it? Thank you, experts! !
Experts, come quickly! It’s urgent. Currently, no standard specifies that an insulation resistance test must be conducted before installation. But in practice, measurements are required in most cases! I just don’t get it.
Experts, come quickly! Urgently needed~
Generally, insulation testing is necessary; new cables often suffer from poor phase-to-phase connections due to issues that occur during production. It’s better to carry out this testing first, rather than having to make corrections after the installation is complete.
