Cable bridge is a kind of product that we often see in our life. It is the standardized production specification of cable bridge formulated by China's Electrical Engineering Committee, which clearly stipulates the small width of bridge frame and the allowable large error range in production. Next, Jinan cable bridge manufacturer will talk about the specific contents of the national standard of cable bridge.
1： The classification of cable tray is based on the material of the tray;
2： The requirements of cable tray, i.e. the service conditions of the product;
3： Test method of cable tray, that is, the method used for various tests of cable tray;
4： The inspection rules of cable tray, that is, the rules to be followed for the quality inspection of products before delivery;
5： The packaging and transportation of cable tray are the standard specifications for how to package and transport the cable tray after production.
In addition, the transportation of cable bridge should be particularly careful. The outer packaging is an effective method to protect the cable bridge from damage. Generally, the outer packaging is required to have certain compressive strength and puncture resistance, which can protect the cable bridge from damage during normal transportation and storage.
At present, there is no uniform and rigid standard for the transportation of cable bridge in China, and the cable bridge should be packaged according to the principle of ensuring the safety of goods transportation. During the transportation, the cable bridge should not be mixed with the materials that are afraid of moisture and heat, as well as flammable, easy to absorb and easy to pollute; When loading the cable bridge, handle it with care. Pay attention to the sign. It is forbidden to roll over and press heavily. Try to drive at a constant speed. Emergency braking is not allowed to avoid severe vibration of the cable bridge.
The above is an introduction to the specific contents of the national standard of cable tray. The specific standard content of each item will be introduced slowly in the future. Today, we will only introduce the contents of the quality standard of bridge production in the national standard.
