Specification for installation of aluminum cable trunking

The wiring ducts are divided into: insulated wiring ducts, mini wiring ducts, open wiring ducts, separate wiring ducts, interior decoration wiring ducts, exhibition partition wiring ducts, integrated insulated wiring ducts , Telephone wiring trough, circular floor wiring trough, open wiring trough, circular wiring duct, cover wiring trough, soft circular floor wiring trough, Japanese telephone wiring trough, etc. There are many types of wire ducts depending on the material. Commonly used are environmentally friendly PVC trunking, halogen-free PPO trunking, halogen-free PC/ABS trunking, steel and aluminum trunking, etc.

Ground metal trunking installation:

1. Materials and equipment

Ground troughs are generally divided into three-trough, double-trough and single-trough, and the specifications are 50*50, 70*50, 100*50, etc. The ground trough is made of stainless steel, hot-dip galvanized, aluminum alloy and other materials, and the surface is not easy to rust. The wireway adopts a threadless interface, and the plastic bridge avoids damage caused by screw damage during transportation or construction. The standard length of the wire groove is 3M, which can be specially processed according to user needs. Wire slot opening size: φ42mm, φ62mm, φ88mm. Slot spacing (mm) is divided into 3000, 2400, 1200, 600 and so on.

Installation tools: screwdrivers, files, hacksaws, thread machines, saws, wrenches, electric hand drills, measuring instruments need glass tube liquid level, liquid level.

Second, the installation process

Positioning according to the picture——Installing the wire groove bracket——Wire groove connection——Installing wire groove powder box——Adjust the level of wire groove and accessories——Check the reliability of connecting parts——Install the protective cover and waterproof sealing treatment before pouring—— Cleaning of protective cover after removal of pouring - installation and wiring of devices such as threading, grounding sockets, etc.

3. Quality standard

Standards and specifications adopted for construction methods:

"Code for acceptance of construction quality of building electrical engineering" GB 50303-2002;

"Code for Installation and Construction Technology of Construction Engineering" (dbj14-032-2004).

Quality Control Measures:

1. Set up a set of plywood brackets every 1.5 meters.

2. The joint must be coated with sealant to prevent concrete from infiltrating into the groove.

3. The junction box and the outlet box must be level.

4. The total cross section of the conductor in the slot shall not exceed 30% of the cross section in the slot.

5. Strictly control the quality of materials, and material acceptance is the responsibility of the purchasers.
