The thickness of the national standard of the bridge, the new standard of the thickness of the natio

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.

The thickness standards of stainless steel bridge are as follows:

The width of the bridge W 150 mm is required as standard.

150 "Bridge width w 300 The standard thickness should be up to mm.

300 "Bridge width w 500 The standard thickness should be up to mm.

500 "Bridge width w 800 The standard thickness should be up to mm.

The width of the bridge W 800 is required with a standard thickness of up to millimeters.

The thickness of the stainless steel tray width W is less than or equal to 150mm.

The width of the stainless steel bridge is 150mm, less than the width of the bridge, W is less than or equal to 300mm, and the standard thickness needs to be reached.

The width of the stainless steel tray is 300mm, less than the width of the bridge, W is less than or equal to 500mm, and the standard thickness needs to be reached.

The width of the stainless steel bridge is 500mm, less than the width of the bridge, W is less than or equal to 800mm, and the standard thickness needs to be reached.

The width of the bridge w is greater than 800mm, and the standard thickness needs to be reached.

Stainless steel jujube trough cable tray function:

Stainless steel trough cable tray is made of 304 stainless steel model material, the surface of Xiangqin Cave generally does not need to be treated, its performance and value are higher than other material trays, plus the trough cable tray itself can be better escorted for 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. <>

The latest national standard thickness specification for cable tray for electronically controlled power distribution.

The latest thickness specification of the national standard for the use of bridge in electric control rooms, power distribution rooms and other similar places is the bridge standard of "JB T10216-2013 cable tray for electronic control and distribution".

The latest national standard thickness specification for steel denier cable tray.

For example, the latest national standard thickness specification used in steel electric cable trays, such as galvanized sheet cable trays, is "T CECS31-2017 Steel Cable Tray Engineering Technical Specification Engineering Construction Standard".

Hello yo dear, I will help you solve this problem The specific solution is as follows: the national standard thickness of the bridge is: 1. The width is less than 100, and the standard thickness needs to reach 1mm; 2. The width is greater than 100 and less than 150, and the standard thickness needs to be reached; 3. The width is greater than 150 and less than 400, and the standard thickness needs to be reached; 4. The width is greater than 400 and less than 800, and the standard thickness must reach 2mm; 5. The width is greater than 800 and less than 1200, and the standard thickness needs to be reached.

Expansion: The bridge is divided into trough cable tray, tray cable tray and cascade cable tray, grid tray and other structures, which are composed of brackets, brackets and installation accessories, etc., which can be erected independently or laid on various buildings (structures) and pipe gallery supports, reflecting the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance.

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".
