What are ASTM D178 Switchboard Mats?
Made of high-quality elastomer and compounds, the AmeriVolt ASTM D178 switchboard mats are dielectric and shockproof. They come in five classes, Class 0 to Class 4, with the working voltage ranges of 1 kV to 36 kV and a thickness range of 3.2 mm to 12.7 mm. The standard color of this matting range is black, but customized dimensions and colors are available.
Workers often have medical emergencies due to electrical accidents such as short circuits, arc flashes, current leakage, and others. Besides, physical accidents such as slipping and falling are also common in workplaces. A reliable insulating mat like the AmeriVolt protects and uplifts performance.
