High-temperature Components

Introduction
Many types of electrical apparatus require functional components that demonstrate resistance to high temperatures (over 200 °C) for long periods of time. Certain non-cellulose materials provide this capability as well as other desired characteristics such as dimensional stability and dielectric strength. Appropriate use of these materials will ensure the mechanical and electrical integrity of the apparatus.
Nomex® is a synthetic aromatic polyamide polymer that provides high levels of electrical, chemical and mechanical integrity. Its longterm resistance to high temperatures extends the life of electrical equipment, reduces premature failures and acts as a safeguard in unforeseen electrical stress situations. Outstanding electrical and mechanical properties and the lack of degradation products like water or gas are some of the additional features of Nomex® fiber based products.
WEIDMANN is a contractual distributor for Nomex®, mainly for applications in fluid impregnated transformers. We glue, weld, slit, punch, cuff Nomex® paper in order to provide the products for direct use without further conversion processes at customers.

Field of Application
Nomex® components are used in hybrid power, traction, mobile, distribution and dry type transformers usually together with paper parts as complete high temperature hybrid insulation kits.
