1. Introduction to the Process JDG pipe (screw-fixed galvanized steel conduit for electrical installation) is a new type of protective conduit for electrical lines. The connection sleeves and their metal accessories are composed of a screw-fixed connection technology, eliminating the need for grounding, welding, and threading. It is the best choice for dedicated protective conduits for insulated wires in both exposed and concealed installations. 2. Advantages and Disadvantages Analysis JDG pipe is a replacement product for various traditional wire conduits such as PVC pipes and SC pipes, representing a breakthrough innovation in the field of building electrical systems using new materials and technologies. JDG pipes use galvanized steel pipes and thin-walled steel pipes with grounding wires, overcoming the complexities of construction and high losses associated with ordinary metal conduits, while also addressing issues such as poor fire resistance and grounding difficulties with PVC pipes. Due to the higher cost of JDG materials compared to ordinary conduits, they are often used in specific areas during construction, such as integrated wiring and fire protection wiring. 3. Technical Standards The JDG pipe series products are designed and produced in accordance with national standards "Special Requirements for Conduits Used in Electrical Installations", fully complying with GB/T14823.1-93 and GB/T13381.1-92 standards. 4. Project Acceptance Project acceptance shall be conducted according to the "CECS 120:2007 Construction and Acceptance Procedures for Screw-Fixed Steel Conduit Wiring" established by the China Engineering Construction Standardization Association.
