Dry Transformer Glass Pultrusion Stays Bones

Dry Transformer Glass Pultrusion Stays Bones

Glass pultrusion stays, including dog bones, vertical bars, cylindrical batten, coattail batten, stay plate etc., are a type of profile produced by a pultrusion process using an alkali-free glass fiber-impregnated thermosetting resin. It has high mechanical strength, excellent electrical properties, and flame retardancy, orrosion resistance, arc resistance and other advantages. It is mainly used for the ventilation cooling between dry transformers and the use of reactors and wave traps.
