What is the PVC trunking<\/h2>\t\t\t\t
\n\t\t\t\t\t

Cable trunking, also known as wiring ducts, distribution ducts, and row cable ducts, are used to organize power cables, data cables, and other wires in a standardized manner and are used to secure electrical equipment to walls or ceilings. Cable trunking is classified into various types based on their material, with commonly used types including environmentally friendly PVC cable trunking, PPO cable trunking, PC\/ABS cable trunking, and metal cable trunking such as steel and aluminum. PVC cable trunking are an electrical wiring material made of polyvinyl chloride (PVC) and have insulating, self-extinguishing, flame-retardant, and arc-proof properties. They come in a variety of sizes, including 20mm\u00d712mm and 40mm\u00d720mm. After installation, wiring is neatly arranged and maintenance is facilitated. Common models of PVC trunking<\/strong><\/a> include the PVC-20 series and the PVC-25 series, which are widely used for internal wiring in electrical equipment to protect circuits and mechanical equipment. According to different usage types, common wiring trunking include insulated wiring trunking, split wiring trunking, mini wiring trunking, partitioned wiring trunking, interior decoration wiring trunking, integrated insulated wiring trunking, telephone wiring trunking, Japanese telephone wiring trunking, open wire wiring trunking, round wiring trunking, exhibition partition wiring trunking, round floor wiring trunking, soft round floor wiring trunking, and covered wiring trunking.<\/p>\n\t\t\t\t<\/div>\n\t\t\t<\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t
