More Information
Product family UWR
Main description Two-component PUR cast resin
Sub description low reactivity to water
Family description Cast resin UWR has been specially developed for filling the cable joints exposed to high levels of humidity. It is characterised by its resistance to water in the liquid and in the solid state and is suitable for the encapsulation which are exposed to high levels of humidity for the following cable types: low voltage polymericinsulated and mass-impregnated paper cables up to 1 kV.
Characteristics Favourable flow properties, High hydrolysis resistance, Halogen-free, Not harmful to the environment, No fracturing under mechanical tension, No fracturing under electrical stress, Excellent adhesion to all cable materials, No fracturing under electrical stress, Excellent adhesion to all cable materials
Family notes Other sizes available on request.
