How to prolong the service life of long-span cable tray the "dry goods" of aluminum alloy cable tray is a cable laying device that makes the laying of wires, cables and pipes standardized, serialized and universal. Lifting section: indicate the elevation change, and it can also be implied by some sample drawings or section drawings. Cables can be stacked at places where cables are inserted. Auxiliary data used in electrical shaft: drill bit, welding electrode, oxygen, acetylene gas, mixed paint, solder, flux, rubber insulating tape, plastic insulating tape, black tape, etc.

Aluminum alloy bridge is a cable laying device that makes the laying of wires, cables and pipes and cables standardized, serialized and universal. Lifting section: indicate the elevation change, and it can also be implied by some sample drawings or section drawings. Cables can be stacked at places where cables are inserted. Auxiliary data used in electrical shaft: drill bit, welding electrode, oxygen, acetylene gas, mixed paint, solder, flux, rubber insulating tape, plastic insulating tape, black tape, etc. I-beam column suspension device the I-beam column with base shall use embedded parts when suspending the device on the cast-in-situ floor or beam, and each column shall use two embedded parts. Cable type the distance from the fixed point is 100 all plastic power cable 150 except all plastic control cable 1000. If no other pipe support is borrowed, it is necessary to establish (support) columns by itself. 3. The cheap processing scale of embedded iron shall not be less than 10 × sixty × 6mm, embedded during civil structure construction, the embedded iron plane shall be close to the formwork and shall be fixed stably.

Together, we have to correct a common mistake: the aluminum alloy bridge factory is mixed with the trunking, thinking that the function is the same, but it is not. Metal trunking is one kind, which is generally made of hot-rolled steel plate. Strong current, defect, control cable. According to the plan, the site investigation records shall be recorded, and the cable application plan shall be prepared, including various standards and types of power cables, control cables, etc. 5-3m. When laying straight, the distance between fixed points shall not be greater than m. The distance between the end holes of two adjacent groups shall be ±. Manual name or schematic diagram of non-standard parts with special requirements. The metal expansion bolt device a is used on concrete components above C15 and solid brick walls, not light walls such as hollow brick walls or ceramsite concrete blocks.

Attention shall be paid to the selection of aluminum alloy bridge to avoid wrong selection without reaching their expected intention. However, it is laid inside and outside the special electrical room (such as power distribution room, electric steam shaft and manual floor). Safety helmet shall be worn when entering the site. The straightening device of cable wiring in the electrical shaft is shown in Figure 5-30. The distribution box device shall be stable and flat, and its straightness is 3mm. The planning must be harmonious with all disciplines to avoid confrontation with process and other equipment pipelines. B tray type frame: slot type, with cracks at the bottom and cover plate. E indoor cable trays and ladders shall not use cables with jute or other flammable data outer protective layer, otherwise the hemp protective layer shall be stripped off for cables with hemp protective layer indoors and inside cable trenches, tunnels and shafts, and the armor shall be treated with anti-corrosion treatment. Movable distribution box, mobile cable reel, theodolite, level gauge, insulation meter, multimeter, high stool, ladder, electric welding machine, etc.
