Insulation Bar for Transformer
Pultrusion is a continuous process for the manufacture of products having a constant cross section, such as rods, beams, channels, pipe, tubing and structural shapes. Pultrusion produces profiles with extremely high fiber loading, thus pultruded products have high structural properties.
The basic components of the FRP profiles for resin and glass fiber (including cloth, carpet, etc.), which is based fibers (including glass fibers, carbon fibers, organic fibers and other metals, non-metallic fiber) as reinforcing material, resin (mainly epoxy polyester resins, phenolic resins) as crosslinking agent and other auxiliary materials supplemented (main materials: mold release agents, curing agents, catalysts, sealing mold agents, UV light stabilizers, mold clean water, gel coat and other ) composite made of.
It has a high temperature, corrosion resistance, high strength, low specific gravity, low moisture absorption, extending small and good insulation and a series of excellent properties. Widely used for mechanical structure, insulation, high-frequency mechanical parts and other functional structural components.
2.Features & Benefits:
2.1 High Strength
Stronger than structural steel on a pound-for-pound basis. Has been used to form the superstructures of multistory buildings, walkways, sub-floors and platforms.
Pultrusions are 20-25% the weight of steel and 70% the weight of aluminum. Pultruded products are easily transported, handled and lifted into place. Total structures can often be preassembled and shipped to the job site ready for installation.
2.3 Corrosion/Rot Resistant
Pultruded products will not rot and are impervious to a broad range of corrosive elements. This feature makes pultrusions a natural selection for indoor or outdoor structures in pulp and paper mills, chemical plants, water and sewage treatment plants, structures near salt water and other corrosive environments.
Glass reinforced pultrusions have low thermal conductivity and are electrically non-conductive.
2.5 Electro-magnetic Transparency
Pultruded products are transparent to radio waves, microwaves and other electromagnetic frequencies.
2.6 Dimensional Stability
The coefficient of thermal expansion of pultruded products is slightly less than steel and significantly less than aluminum.
2.7 Parts Consolidation
Custom designed pultrusions allow multiple discrete parts to be designed and fabricated into a single part thus reducing the number of fabricated parts and the need to join these parts together.
2.8 Low Temperature Capabilities
Glass fiber reinforced pultrusions exhibit excellent mechanical properties at very low temperatures, even -20ºC. Tensile strength and impact strength are greater at -20ºC than at +25ºC.
Pultruded profiles are pigmented throughout the thickness of the part and can be made to virtually any desired custom color. Special surfacing veils are also available to create special surface appearances such as wood grain, marble, granite, etc.
