Multiple Names, Multiple Applications: The High Potential Voltage (Hipot) Test
Posted on 2/26/25 2:44 PM
Dielelectric Voltage-withstand or Dielectric-strength tests are often referred to as the High Potential Voltage “Hipot” test. It’s a common yet important safety and diagnostic tests used for electrical and electronic components and devices—it can be used in both design and production phases in the manufacturing of electrical products.

To “B” or not to “B” . . . Crimping Flexible Power Cords
Posted on 6/27/24 2:37 PM
By automation or manually by hand, Interpower® crimps bridges for country-specific plugs, and IEC 60320 connectors onto miles of flexible cable it manufactures each year. For cord sets, the optimal crimp is one that provides the most electrical contact between the conductors of stranded wire and its bridge or connector—the B crimp provides optimal electrical contact for flexible cable.

Using Strain Reliefs/Cable Glands to Prevent Acute Bend Radius in Power Cords
Posted on 1/23/24 11:49 AM
Cable is a sleek composite of resins and metals which are vital materials of making world-class power cords and cord sets. While dependable and durable, even essential to modern-day life, cable is also susceptible to acute bending, especially near the point where the cord exits the equipment. Underneath the smooth resinous skin of our example cord, lay three conductors of extruded copper wire. If those wires are extremely bent or otherwise damaged, the result could be loss of electrical continuity or shortened lifespan—protecting your cord’s bend radius helps maintain connectivity. And understanding your cord’s recommended minimum bend radius for cable is critical to the maintenance and longevity of the cable and the machines and equipment powering them.
