Steel pipe we all know what it is, and powerful PVC casing electrician is a joined with PVC flame retardant materials made of opaque white threading pipe, applicable to within the walls of threading, such as wires, audio cable, video cable, telephone lines and other. So compared with the steel pipe, what are the characteristics of it?
1, anti pressure is strong: PVC electrical casing can withstand strong pressure, can be bright or dark deposited in the concrete, do not worry about compression.
2, corrosion resistance, pest control: PVC bushing has corrosion resistance, while the tube does not contain plasticizers, therefore no pests.
3, flame retardant is good: PVC electrical casing on the flame burning away, can quickly self interest, can avoid the fire spread.
4, insulation performance is strong: PVC electrical casing can withstand high power and not be breakdown, can effectively avoid leakage, electric shock accident.
5, the construction is convenient: the quality of the PVC electric bushing is light, only the 1/5 of the steel tube; and easy to bend, insert a section of bending spring in the tube, can be bent at room temperature.
6, saving investment: compared with the steel tube, the cost of materials and construction and installation costs can be greatly reduced.
