Construction steel cable tray supply

construction steel cable tray supply qhcmliwu3 Installation of supports and hangers: the quality of supports and hangers of cable tray should meet the current relevant technical standards. When the cable tray is laid horizontally, the support span is generally 1.5~3, which affects the market share. When the vertical laying is tried, the fixed spacing should not be greater than 2m, the horizontal height difference between two adjacent cable tray arms should not be greater than 10mm, and the vertical deviation of the vertical center line of two adjacent cable tray arms should not be greater than 20mm. Advantages of galvanized cable tray: it has very good corrosion resistance, long durability, much longer service life than ordinary cable tray, high degree of industrialization and stable quality. Therefore, it is widely used in outdoor environments that are seriously corroded by the atmosphere and difficult to maintain. (1) With a thick and dense pure zinc layer covering the steel surface, it can avoid the contact between the steel substrate and any corrosive solution and protect the steel substrate from corrosion. In general atmosphere, a thin and dense zinc oxide layer is formed on the surface of the zinc layer, which is difficult to dissolve in water, so it plays a certain protective role on the steel matrix

FRP hull and shore have our technical department strictly control the damage such as scratches caused by the friction and collision of stones, concrete structures and metal components, and protective measures should be taken. 11. If damage is found, repair it in time. If resin peeling, deep scratches and exposed fibers are found, they must be repaired in time, otherwise the damage will be accelerated due to the infiltration of water. 12. When not in use, especially in cold winter, it should be placed ashore. Due to the certain water absorption of FRP, water can gradually penetrate into the interior along the micro channel of the interface between glass fiber and resin, and the strength of FRP gradually decreases. Especially in winter, the infiltrated water freezes when it is cold, which expands the seepage channel and causes greater harm. Although the FRP cable tray is very corrosion-resistant and durable, it still needs maintenance after exposure to the wind and sun. Specializing in the production of cable tray factory analysis FRP pultrusion profile application fields pultrusion profile application fields: sewage treatment, water supply and drainage engineering, petrochemical engineering, power engineering, papermaking engineering, building decoration engineering, textile and printing and dyeing projects, shipbuilding projects, etc

the cable tray produced by the manufacturer of fire-proof cable tray shall include its own weight, as well as the mechanical load of wires and cables of Ningbo Institute of materials technology and engineering, Chinese Academy of Sciences (nimte), and the working uniform load shall not be greater than the selected load rated uniform load. When the cable tray bears the rated uniform load, the relative deflection of epoxy resin and epoxy resin composite should not be greater than 1/200. Most modern power transmission systems rely on high-voltage cables for power transmission, so the standardization and standardization of cable trays are also very important. In many transmission scenarios. High voltage environment is inevitable, and it is difficult to manage and control transmission cables up to 10kV. At this time, cable trays are needed. The cable tray can be generalized and standardized, which is conducive to the transportation and management of transmission cables. The cable tray is laid in the transmission system, indoor distribution system and outdoor transmission system to just ensure the safety of the circuit

the allowable deviation of straightness and verticality of the horizontal or vertical laying part of the bridge shall not exceed 5mm. In order to prevent mortar from entering, the periphery of each connection is smeared with special glue, the covers of each junction box and outlet box are tightened, bound with iron wire, and the end is blocked with plastic. When pouring concrete, special personnel shall be assigned to take care of it, and problems found shall be handled in time. 3) Welding of jumper wire: determine the specification of jumper wire according to the construction specification. The welding surface at both ends of the ground wire shall not be less than 6 times the cross-section of the jumper wire, and the weld shall be uniform and firm. 4) Wiring in the groove: first clean the bridge, insert the belt line to the outlet, then tie the cloth strip to one end of the belt line, pull out the cloth strip from the middle end, and repeatedly clean up the sundries and ponding in the bridge, or blow out the sundries and ponding in the bridge with an air compressor. Before setting out, check whether the day protection at the connection of pipe and bridge is complete. 5) For line inspection and telemetry, refer to the relevant parts of the installation project of threading wires in the pipe

nowadays, there are not a few cable tray factories nationwide in China. It is not very difficult for consumers to purchase really suitable products. As long as they purchase according to the correct problems, they can obtain high-quality and low-cost products. It should be noted that nowadays, many cable trays have professional stations, and it is a very good way to purchase through these stations, because the prices of products purchased through Internet channels are low! During the period of high-speed industrial development, cable tray manufacturers have more and more extensive uses. From determining the material of cable tray, designing cable tray, and then determining the model and size of cable tray, these Wanbo cable tray manufacturers are strictly controlled, strictly adhere to the purpose of good quality and low price of cable tray, and strictly follow the national standards of cable tray, Produce cable tray models and specifications that satisfy customers

(3) choose the right manufacturer. The specifications and pictures of galvanized cable tray given by many manufacturers may look similar, but in fact, their product quality is still very different. Therefore, we must choose to cooperate with regular manufacturers, who can provide us with various types of products with guaranteed quality and after-sales service. We can rest assured when cooperating. The above is the introduction of the method of selecting the specifications and pictures of galvanized cable tray. I believe that through the above introduction, you can have a new understanding of galvanized cable tray. The company's products and services have been highly praised by the majority of customers. Here we solemnly remind the majority of customers who buy cable tray to identify the manufacturer and buy carefully! Aluminum alloy bridge has the characteristics of beautiful appearance, simple structure, unique style, large load capacity, light weight and so on. After the surface of aluminum alloy cable tray is oxidized, it is not only resistant to corrosion, but also to electromagnetic interference, especially shielding interference, which is irreplaceable for steel cable tray
