The LED lighting renovation project of Zhongshan East Street lamps in the urban area can be said to be a representative project of Rugao's municipal green development. This road originally used sodium lamps for lighting. In order to promote economical lighting, 240W LED street lamps replaced 294 500W sodium lamps, and 120W LED street lamps replaced 154 250W sodium lamps. The average power saving rate is 65%, which saves 440,000 kWh per year. Save more than 390,000 yuan in electricity bills.
After street lamp LED transformation, the average illuminance of the road surface has reached 1.5 times that of the original sodium lamp. The lamp life of more than 50,000 hours is far beyond the 8,000 hours of sodium lamp life. The long warranty period of 5 to 6 years is realized, and the annual power saving is 2.685025 million kilowatt-hours. , Saving 2.368192 million yuan in electricity costs, reducing CO2 emissions by 1022.99 tons and saving 886.06 tons of standard coal.
Fiberglass woven roving is a versatile composite reinforcement material composed of continuous glass fiber filaments coated with a coupling agent or binder. The glass fibers are woven into a fabric with a plain or twill weave pattern, providing strength and stability.
With its high strength-to-weight ratio, fiberglass woven roving is an ideal reinforcement for plastic composites across many industries. It exhibits high tensile strength along with impact, chemical and heat resistance. The woven construction provides multi-directional reinforcement, dimensional stability, and ease of handling.
Fiberglass roving is compatible with polyester, vinyl ester and epoxy resins. It is widely used as a reinforcing material in boat hulls, auto bodies, bathtubs, roofing, piping, storage tanks and other composite components. It is also valued for electrical insulation applications.
When saturating the woven roving with resin, proper wet-out and cure is critical to achieve optimal mechanical properties in the finished composite. Fiberglass roving comes in various weights, widths and weave patterns to suit the reinforcement requirements of the application. With its combination of high strength, corrosion resistance, and cost-effectiveness, fiberglass woven roving continues to be a staple composite material across many industries.
