Dielectric Insulator

Electrical & Electronic Dielectric Insulator Manufacturer

To meet many strict product requirements as well as government and industry regulations, manufacturing companies are required to test their products using the Insulation Resistance (IR) Test. Insulation resistance is a characteristic of an insulating material that, when exposed to voltage, the leaking current flowing through it stays within acceptable limits. This test is a simple and straightforward procedure; find two conductive points between which there is a dielectric insulator, connect the two points to an insulation tester and measure the resistance of the insulation between the two points.

For manufacturing company’s products to pass this simple, yet strict test regulation, manufacturers need a reliable dielectric insulator manufacturer to produce these product parts that can then be applied to their product.

Custom Dielectric Insulator Manufacturer

Aluma Graphics can manufacture a wide range of electrical and electronic dielectric insulators for industries of all kinds. As a custom manufacturer of electrical insulators, we can produce dielectric insulators that are customized for nearly any type of conducting material. Aluma Graphics offers the most common materials with specific options and print preferences.

Electrical & Electronic Dielectric Insulator Materials

  • Polyester is a strong, durable material that exhibits a high conductivity resistance
  • Fish Paper (Vulcanized Fibre) is a strong, flexible, fibrous dielectric paper that resists moderate heat and increases dielectric strength as an insulator while also having high mechanical strength
  • Nomex paper is an insulation paper that offers high inherent dielectric strength as an insulator as well as mechanical strength, flexibility and resilience
  • Any of the materials can be made with or without adhesive and can be printed or left blank
