Coated fiberglass sleeves with PVC, acrylic, PU and silicone

GSGFF Hochtemperatur Glasseidenschlauch


We offer a wide range of insulating glass fibre hoses, with a wide variety of materials and impregnations. The coating of the glass fibre hose with its defined surface, offers high dielectric strength (up to 20kV), and improved mechanical properties.
Various types cover every technical requirement. Applications in transformers, oil-cooled or air-cooled electric engines, or applications with aggressive environmental conditions. These insulation tubings provide effective and long-lasting cable protection.
Some types offer protection even in harsh environments, such as in a foundry or near to industrial welding machines. We offer protective hoses with a FeO and Silicone cover, which can even withstand drips of liquid metal.
The increasingly popular acrylic coating are available in several variants. Our standard with 3kV dielectric strength, or the UL-listed variant with 7kV.
We develop hoses with custom specific properties according to your needs, for the automotive industry, the e-mobility sector, engine construction, appliances
