SMC insulating boards offer high mechanical strength, flame retardancy, and excellent electrical insulation properties, surpassing UPM203. They also boast high arc resistance, dielectric strength, and voltage resistance. They have low water absorption, stable dimensions, and minimal warping. These boards are primarily used in various insulating panels for high, medium, and low-voltage switchgear. The unique properties of SMC composites address the drawbacks of wooden, steel, and plastic meter boxes, such as aging, corrosion, poor insulation, poor cold resistance, low flame retardancy, and short lifespan. Glass-reinforced plastic meter boxes provide excellent performance, including sealing and waterproofing, corrosion resistance, anti-theft electricity, and no need for grounding wires. They are aesthetically pleasing, with locks and lead seals for protection, offering a long service life. SMC distribution boxes, SMC meter boxes, SMC glass-reinforced plastic meter boxes, and SMC meter cabinets are widely used in rural and urban network transformation projects.
