Product Details
In electrical safety, barrier board sheets (often referred to as "Red Barrier Boards" or GPO-3 sheets) are rigid insulating materials used to prevent electrical flashovers and protect personnel from accidental contact with live components. They are critical in switchgear, control panels, and high-voltage transformers. Key Material Types GPO-3 (Red Barrier Board): The industry standard for high-voltage insulation. It is a glass-reinforced thermoset polyester sheet known for its arc resistance (≥180s) and high Comparative Tracking Index (CTI ≥600V), which prevents carbon paths from forming on the surface. Epoxy Glass Laminates (FR-4/G-10): Common in lower-voltage applications or where superior mechanical strength and moisture resistance are needed. Intumescent Composite Sheets: Specialized barriers (like those from 3M) that provide up to 4 hours of fire protection by expanding when exposed to heat, sealing penetrations against flames and toxic gase. Safety Features & Benefits Arc & Track Resistance: Prevents surface flashovers caused by contaminants, moisture, or animals in switchgear cabinets. Flame Retardancy: Most high-quality barrier boards meet UL 94 V-0 standards, meaning they are self-extinguishing and do not emit toxic halogens. Mechanical Integrity: Provides structural support for busbars and can withstand significant impact and vibration without cracking. Visibility: The distinct red color (common for GPO-3) serves as a visual warning to identify high-voltage hazard areas.
