Barrel Insulation Frame

The steel structure material is hot-plated, the surface of the insulator is polished and white glaze is applied.

The insulating body of the barrel insulator frame is a high-alumina porcelain with a content of 95% alumina, which has excellent pressure resistance, good compactness, excellent insulation performance and excellent thermal shock resistance; the surface of the steel structure is treated with hot plating. The method of zinc improves the corrosion resistance of metal materials and is suitable for all kinds of weather. For specific installation dimensions or special requirements, please consult the corresponding salesperson.
