Insulation oil plays a critical role in maintaining the safety and performance of electrical equipment by preventing electrical breakdown. Selecting oil that meets the appropriate withstand voltage standards helps ensure reliable insulation performance. Here’s an overview of the voltage withstand requirements for various levels of insulation oil.
Withstand voltage standards are benchmarks that indicate the voltage level an insulation oil can safely withstand without electrical breakdown. Meeting these standards helps prevent equipment failure, minimizes maintenance, and ensures stable operation.
The insulation oil withstand voltage standards vary by the operating voltage of the equipment:
For Equipment Below 15KV
For Equipment at 15KV - 35KV
For Equipment at 66KV - 220KV
For Equipment at 110KV - 220KV
For Equipment at 330KV
For Equipment at 500KV
When selecting insulation oil, use these voltage standards to match the oil’s withstand voltage capability with the equipment’s operational requirements:
By choosing insulation oil that meets these withstand voltage standards, technical and procurement teams can ensure that equipment runs reliably, reduces maintenance needs, and operates safely at various voltage levels.
