Glass-Fiber Reinforced Plastic (GFRP) Bridge Trays Application
Glass fiber reinforced bridge beams are widely used in the power distribution and transmission equipment industry, offering excellent corrosion and permeation resistance, overall good performance, strong impact resistance, high hardness and smoothness on the inner surface, and the advantage of being non-prone to scale buildup.
The characteristics of glass fiber reinforced plastic bridge beams:
1. Anti-corrosion and impermeability
Choose high-quality, corrosion-resistant unsaturated polyester resin or vinyl resin for the inner surface layer, reinforced with high-strength surface mat or chopped strand mat, offering excellent sealing and no cracking.
2. Good overall quality
The glass fiber reinforced plastic bridge tray is made using a one-piece molding process, featuring no joints, offering high load-bearing capacity, good rigidity, strong impact resistance, and the electrolytic reaction tank will not develop cracks after long-term use.
3. Exceptional performance
The glass fiber bridge tray is made of excellent insulating material, does not conduct impure current, and is non-conductive with an insulation resistance of not less than 10 to the 12th power ohms both in normal conditions and after being submerged for 24 hours.
Relative dielectric constant not greater than 4.5, arc resistance greater than (s) 150
Leakage Tracking Index (v) Greater than 180
4. Service Life
Fiberglass reinforced plastic (FRP) electrolytic reaction tanks commonly used indoors typically have a lifespan of around 30 years, with low operational costs and minimal maintenance required.
5. Lightweight quality
Glass fiber reinforced plastic bridge supports have a density of 1.8-2.0 kg/cm³, roughly one-third that of carbon steel, with high mechanical strength. They combine the rigidity of metal bridges with the toughness of glass fiber bridges, exhibit excellent corrosion resistance, strong anti-aging properties, attractive appearance, easy installation, and long service life. Epoxy resin and epoxy resin composite cable bridge supports are suitable for use in highly corrosive environments, large spans, and heavy load conditions.
