What knowledge should be essential for circuit construction cables?

Circuit construction is not to be ignored in the process of decoration and construction of a, if not careful sloppy, the consequences can be very troublesome. I would like to introduce you to some of the basic issues of circuit construction. Circuit construction process: according to the design requirements of the line → circuit budget → cut dark grooves and holes through the wall → water pipe measurement under the material → pipe support bracket installation → water pipe pre-installation → formal installation of fixed → water test, pressure.

Circuit construction precautions: 1, circuit construction of the expected circuit transformation line for flick line confirmation. 2, flick line confirmation after signing the plumbing and electrical confirmation, budget circuit (strong and weak power) transformation costs, the customer signed to confirm. 3, the circuit transformation program is confirmed with the masonry machine along the line of the groove. 4, circuit construction is completed after the insulation resistance value shaking records. 5, the circuit pipeline fixed every 40cm plus a card. 6, electrical line head connection uniform use of terminal connection. 7, lighting in the ceiling light head line must use flame retardant hose. 8, lighting in the ceiling light head line must use fire retardant hose. A card, elbow on both sides of the 100mm to 150mm fixed a card. 6, electric line header connection using a unified terminal connection. 7, ceiling lighting header line must use flame retardant hose. 8, all exposed wire header uniform use wire protection cap to protect against electric shock. Circuit construction process is introduced: 1, 4F explanation (4 effective prevention): (1), trenching shallow, effective prevention of cutting off the rebar home improvement project circuit construction is a secondary transformation project, circuit construction should minimize the damage to the main structure of the building, Coda's proprietary single-pipe single-wire system piping construction process, due to the small diameter of a single pipe, the lines laying side by side, the wall trenching shallow, effective prevention of cutting off the wall! The risk of the main structural reinforcement, to solve the industry's largest problem in the transformation of home furnishing circuit, but also to solve the sheath line buried, it is difficult to draw a line, change the line of the problem. (2), single-pipe, single-line construction process, each tube only wear a wire, effectively preventing short circuits between the wires in the tube, and effectively avoid the occurrence of kinks, twists, or dead ends in the pipeline wire. (3), the same color identification of the pipeline, to prevent the phase line connection error; Coda developed a proprietary PVC flame retardant line pipe, the line pipe red for the phase line, blue for the zero line, yellow for the ground line, white for the switch circuit branch line. The same color identification effectively prevents connection errors. Red for the phase line: 2, innovative construction technology: home improvement circuit construction and remodeling 4F level of single-pipe, single-wire laying process, home improvement circuit remodeling in the advanced construction technology and the latest construction methods.

3、Saving construction technology: Due to the single-pipe single-line system laying process whether it is PVC flame retardant pipe or galvanized line pipe, its caliber is small, pipe diameter is fine, can save raw materials, low cost, the price is more reasonable. 4、Good intuition: It is conducive to direct consumer inspection, because the 4F single-pipe single-line system laying process of the line pipe itself has a 顔 color identification function, which makes it easy for consumers to directly check, blue PVC flame retardant wire box, the branch line outlets of the sub box are equipped with various line sealing marking, respectively, with "+", "-" "=" "G". Blue PVC flame-retardant wire box, the outlet of each branch line of the distribution box are equipped with each line sealing marking, respectively, with "+", "-" "=" "G The "+", "-", "=", "G" marking indicates the phase line, zero line, ground line, switching circuit branch line, which is helpful for the future overhaul and maintenance of the wires and lines.
