High Insulation Dogbone For Transformer
Insulation dog bone is formed by the pultrusion of a non-alkaline fiber glass yarn impregnated with unsaturated polyester resin in the traction of the force through a hot die. Mainly used for electrical equipment insulation structure. Shapes are rectangular, I-shaped, angular, T-shaped, groove-shaped, circular tube-shaped, cylindrical, and other shapes.
Dog Bone Pultruded Profiles are made from glass fiber as reinforcement ，synthetic resin as matrix by
pultrusion process. The resin matrix can be polyester，vinyl ester or epoxy resin.
Dog Bone Pultruded Profiles have very smooth surface， high mechanical strength ，excellent electrical
properties，superior flame resistance，high arc and carbon track resistance,and good thermal properties.
Thermal class is available for Class F and H.
Dog bone specification:
1).it is class F and H insulation material.
2).size: 8x10mm, 6x6mm, 4×8mm,18×20mm, 10×16mm, 16×16mm etc.
3).High mechanical strength
4).Excellent electrical isolation
3. Color: white
Insulation pultrusion profiles are widely used in railway ,subway ,tramway ,Power
electrical insulation ,cable tray channel,ladders,reinforce core for cable;rib
structure for green house,drain channel, water transporting system ,tooling
handles,sport apparatus, garden facilities ,structure for shelters,removable
housed and refrigerate vehicle shelf.
