SMC Insulating Sheets are made ofUnsaturated PolyesterGlass fiber reinforcedSheet molding compoundPlease provide the Chinese content to be translated.Molded shapingA variety of colored sheet products. Abbreviation for Sheet Molding Compound, which is a type of sheet molding compound. The main raw materials include GF (specialty yarn) and UP ( ).Unsaturated resin）、Low-shrinkage additiveComposed of MD (filler) and various additives. It first appeared in Europe in the early 1960s, and around 1965, the United States and Japan developed this process. China introduced the SMC production line and technology in the late 1980s.

Highly mechanical strength, flame retardancy, and excellent electrical insulation properties, second only to UPM203; excellent arc resistance, dielectric strength, and high voltage endurance; low water absorption rate, stable dimensions, and minimal warping. SMC insulating boards are primarily used in high, medium, andLow-voltage switchgearA variety of insulating spacers.SMC Composite MaterialsUnique performance that addresses the shortcomings of wooden, steel, and plastic electric meter boxes, which are prone to aging, corrosion, poor insulation, low cold resistance, poor flame retardancy, and short lifespan. Glass fiber reinforced plastic electric meter boxes offer excellent properties, including absolute sealing and waterproofing, corrosion resistance, anti-theft electricity performance, and do not require grounding wires. They have an aesthetically pleasing appearance, equipped with locks and seals for safety protection.Long-lasting, SMC distribution boxes/SMC meter boxes/SMC fiberglass meter boxes/SMC meter cabinets are widely used in rural and urban network renovation.
