Pvc cable trunking is a rigid pipe containing polyvinyl chloride resin. The small-diameter trunking can be bent which makes it widely used in many complex wiring requirements, and is convenient for outdoor and family use.
Generally, the specifications include 20x12mm, 25×12.5mm, 25x25mm, 30x15mm and so on. According to the outer diameter of trunking profile, PVC wire duct can be divided into D16, D20, D25, D32, D50, D110 and other specifications.
PVC trunking can be divided into pull out trunking, mini trunking, integrated insulated trunking, telephone trunking, open trunking, circular wiring pipe, circular floor trunking, cover trunking, etc,
