What is the national standard thickness of pallet steel bridge?

The type of cable tray depends mainly on the composition of the cable to be laid and the environment in which it is used. Here are some commonly used types of cable trays in the market for reference:

Trough cable tray: A trough cable tray is a completely sealed cable tray that is shaped like a box and is used to lay cables.

Ladder cable tray: the whole is stepped shaped, the center is welded with crossbar steel support, light weight, low cost, strong bearing capacity and good air permeability.

Tray cable tray: A tray tray is a semi-sealed cable tray that is very similar to a trough cable tray. There are heat dissipation holes at the bottom.

Based on the steel cable tray engineering design code CECS31 91, it was revised by the Electrical Engineering Committee of China Engineering Construction Standardization Association.

National standard thickness of cable tray.

The width of the cable tray <100 and the standard thickness needs to be up to 1mm

100 "Cable Tray Width< 150 The standard thickness needs to be reached.

150 "Cable tray width< 400 standard thickness needs to be reached.

400 >> Cable Tray Width<800 Standard thickness needs to be up to 2mm

800 "Cable Tray Width< 1200 Standard thickness is required.

Pallet steel bridge is commonly used (national standard) thickness is: national standard), national standard), national standard).

The pallet steel tray is to use electrolysis equipment to remove oil, pickle, and then put the cable tray into a solution composed of zinc salts, and connect the negative electrode of the electrolysis equipment.

Place the zinc plate on the opposite side of the pallet steel bridge, connect the positive electrode of the electrolysis equipment to turn on the power supply, and use the current from the positive electrode to the negative electrode to move directionally on the pallet steel bridge will deposit a layer of zinc, the pallet steel bridge is first processed and then galvanized, which is its anti-corrosion effect.

The national standard thickness standard table of the bridge generally refers to the standard of the minimum plate thickness of the bridge, in terms of the 2013 national standard for the bridge, the 2013 national standard for the bridge refers to the "JB T 10216-2013 Cable Tray for Electronically Controlled Power Distribution", record number: 44087-2014, which is used to replace the "JB T 10216-2000 Cable Tray for Electronically Controlled Power Distribution" standard, issued on December 31, 2013 and implemented on July 1, 2014. Issued by the Ministry of Industry and Information Technology of the People's Republic of China. The standard thickness of the bridge refers to the thickness of the bridge plate, and the specific standard is shown in Table 9 of the "JB T 10216-2013 Cable Tray for Electronic Control and Power Distribution".

Stainless steel trough cable tray function.

Introduction: Stainless steel trough cable tray is made of 304 stainless steel.

The model material is manufactured, the surface generally does not need to be treated, its performance and value are higher than other material trays, and the sealing of the trough cable tray itself can better escort power transmission. The presence of Ni element in the composition of 304 stainless steel is extremely important, which directly determines the corrosion resistance and value of 304 stainless steel.
