High Voltage Insulation Materials

High Voltage Insulation Materials for Power Generation and Electric Coil Manufacturers

We believe in building success from the inside out. Working with high voltage leaves little room for error.

Our partners trust us to provide high performance mica insulation tapes to optimize ground wall thickness and improve voltage endurance. Coupled with premium conductive and gradient tapes, Electrolock provides materials and engineering support from coil design, manufacturing and testing. Because what you can’t see on the outside makes all the difference to our customers.

Your custom solution is only a click away.
