UL Categories of Adhesive Tapes for the Energy Industry
Insulating TapeTeraoka has a large selection of electrical insulation tapes that have acquired the following UL certifications. Transformers with permitted
maximum temperature of 105˚C or higher are required to be certified by UL. Teraoka products are used in many insulation systems.
•UL1446: Electrical Insulation System (EIS)•UL746B: Long Term Property Tests for Plastic Materials [Temperature Rated]
Dielectric breakdown voltage, tensile strength, etc. are included in temperature evaluation items for checking if a product can hold an initial characteristic
within a certain range when exposed to a certain temperature for 100,000 hours.

•UL746A: Short Term Property Tests for Plastic Materials [Comparative Tracking Index (CTI)]

This is a phenomenon in which repeated small electric discharges on the surface of an insulator create carbonized conductive tracks on the surface of theinsulator, eventually reaching dielectric breakdown.
The higher the value, the better the resistance to tracking.

•UL510: Flame Retardant

Tests for Flame Retardancy of Insulating TapePlastics

Adhesive Tapes for
the Energy Industry•UL94: Tests for Flammability of Plastic Materials

This is the flame retardancy evaluation commonly conducted by UL. This certification is obtained for other than insulating tape applications.

UL Tests for Flame Retardancy
Flame retardant adhesive tape has a high degree of fire resistance due to its self-extinguishingbase support or adhesive, therefore, it does not catch fire easily even if it touches flame. Even
if it is touched by an intense fire and burns, the burning rate is significantly slower than for
normal adhesive tape and the spread of flames is minimal.

supports the energy industry with adhesive tapes.

In a variety of areas, Teraoka adhesive tape technology is indispensable in our lives.

High-voltage power transmission

Electric generator

Teraoka technology is used in high-voltage
power transmission, which efficiently transmits
the electricity generated at power plants.

Hydroelectric power generation captures the energy of water
as it flows from mountains back to the sea. Teraoka
technology is used in the turbine to supply electricity to homes.

Superconducting coil
Teraoka technology is used in superconducting
coils, which support the powerful magnetism formagnetically levitated (Maglev) linear motor cars.

Transformer
Wireless power supply

Teraoka technology can be used for wireless power
supplies. not only for mobile devices but also for futureapplications that require large amounts of electrical power.

Electrical transformers are indispensablefacility for voltage conversion. Teraoka
technology has been used for many years.

Smart Grid
Teraoka technology is used in electricautomobiles as well as easy-to-use, efficient
future smart electrical power grid systems.
