Where can I make a cable tray The quality of the cable tray is better?

Hello Cable tray is divided into trough type, tray type and ladder frame type, grid type and other structures, which are composed of brackets, brackets and installation accessories. The full name of the rigid structural system with closely connected support cables composed of straight sections, bending, tee, and crosses components, supporting arms (arm brackets), hangers, etc., which are composed of trough, tray or cascade straight sections, bends, tees, and crosses, as well as brackets (arm brackets), hangers, etc. The products that have received wide attention are made of high-quality cold-rolled steel plates, and the surface processes include cold galvanizing, hot-dip galvanizing, electrostatic spraying, fireproof coatings, baking paints, etc.

Selection of cable tray type and variety:

1. When the cable network that needs to be shielded from electrical interference or has the requirement of protecting the external (such as corrosive liquid, combustible dust and other environments), the (FB) trough composite anti-corrosion shielded cable tray (with cover) should be selected

2.In highly corrosive environments, (F) composite epoxy resin anti-corrosion and flame-retardant cable trays should be used. The same material should be used for the bracket and bracket to improve the service life of the tray and accessories, and the cable tray.

In the easy to accumulate dust and other places that need to be covered, it is advisable to add a cover plate.

3. In addition to the above conditions, tray type, trough type, stepped type, glass anti-corrosion flame retardant cable tray or steel ordinary cable tray can be selected according to the environmental and technical requirements of the site. In the environment or outdoor places that are prone to dust accumulation and other needs to be covered, it is advisable to add a cover.

4. In the public passage or outdoor crossing road section, the bottom of the bottom step should be added with a backing plate or a tray should be used in the section. When the large span crosses the public passage, the load capacity of the bridge can be increased according to the user's requirements, or the row frame can be selected.

5. Composite bridge (FB) should be selected for large span (>3m).

6. Composite epoxy resin bridge (F) should be used outdoors.

The cable tray model should include the following:

1. Name: It can be represented by the first Bixiao orange letter in the uppercase Chinese hand group pinyin;

2. Structural form; Non-perforated tray (PL), perforated bridge search tray (P2), ladder frame (T);

3. Specifications: The straight section and bend of the pallet and ladder frame are marked with width and height in turn; Attachments and supports and hangers indicate the dimensions of one or several of the main technical characteristics;

4. Category of anti-corrosion layer: color steel composite coating (CQ), corrosion-resistant VCI bimetallic composite coating (VS), hot-dip galvanizing (R), electro-galvanizing (D), powder coating (P), others (T), if the same anti-corrosion layer category needs to be subdivided according to different environmental conditions, the subdivision code should be indicated;

5. Material: stainless steel (S).

Cable trays are classified as: tray cable trays, staged cable trays, trough cable trays, combined cable trays, long-span cable trays and mesh cable trays. Recommend Shanghai Changpeng metal products, you can ask to see.

Chang Peng electric pants Qi cable bridge Hu Liang mausoleum specification selection:

1. In order to prevent the size of the cable tray from being too large or too tight, the Code for Electrical Design of Civil Buildings (JGJ16-2008) stipulates: "The ratio of the total cross-sectional area of the cable to the cross-sectional area in the tray shall not be greater than 40% of the power cable; The control cable should not be larger than 50%. ”

2. All kinds of bends and accessories should meet the engineering layout conditions and match the bridge.

3. The selection of support and hanger specifications should be configured according to the specifications of the bridge, the number of layers, the span and other conditions. and should meet the requirements of the load.

4. The section that requires the bridge to be fireproof must be made of steel or non-combustible and flame-retardant materials.

Steps to select a tray:

1. Determine the width of the tray, the number of layers, the type and spacing of the support points, and the distribution of cables on each layer of tray.

2. Calculate the uniform load (kn m2) of each layer of cable key, and preliminarily determine the model and specification of the bridge.

3. Check the strength of the bridge according to the maximum total average distribution load value of the cable.

This mainly depends on the fact that you live in **. Now the market of cable tray is developing rapidly, there are many cable tray manufacturers in China, and the brand of cable tray has increased a lot, but the quality difference is very large, so it is recommended to screen carefully.

In fact, there are not many brand electric bridge factories, but the quality index must be passed, and there may be a good brand with a supervision certificate.

First understand whether the cable tray manufacturer has the production capacity, whether it can provide samples, product inspection reports, product certificates, and so on.

We will need to count the quantity, width, height and material of the purchased cable tray and other parameters, so that the cable tray manufacturers can provide accurate **. Because these parameters are not counted, cable tray manufacturers are unable to give, raw materials fluctuate greatly, specifications are many, and different materials will affect the cable tray.

It is necessary to carefully build the process of the material tray, and there should be no distortion, black spots, rust, paint loss and other phenomena on the surface. If conditions permit, you can go to the site to inspect the scale and supply capacity of the partner's factory.

Is there a good cable tray nearby? Where is the manufacturer? You can go to that building materials city and you'll have it.

There are still some good electrical boxes nearby, and there are still some bridges, but you still need to look for this carefully, because sometimes you can't see it from the appearance, the key depends on his technical level?

Where are you near me to know what are the cable tray manufacturers near you?

There are a lot of good cable tray manufacturers nearby, and I will help you take a look at your location.

Hengshui City, Hebei Province, Zaoqiang County, Gangqi Company.

Before you choose a galvanized tray manufacturer, you need to pay attention to the following points:

1.Be sure to indicate the actual thickness of the plate to avoid problems during the supervision and acceptance. At present, the industry is highly competitive, in the case of low profits.

In this case, in order to avoid not stressing the credibility of manufacturers to provide substandard products to make good and earn profits, we must pay attention to the thickness of the plate. By country.

The actual thickness of the standard iron plate is allowed in the country between .

2.Supply cycle, in order to receive orders, in general, the supply cycle promised by the manufacturer is shorter, in order to catch up with the construction period, it is necessary to spray the production of fireproof paint.

products, sent to the construction site without completely drying, coupled with the human factor at the time of delivery, will cause a large area of paint to fall off, in your application.

The bridge has not been completely completed, so the construction period must be guaranteed on the premise of ensuring quality.

Attachments, which are the most easily overlooked, are also a large proportion of the entire contract, but these additional materials are average.

None of them are produced by manufacturers, they are sent to manufacturers by professional manufacturers, and some manufacturers are sold to customers with high profits, so the best accessories must also be compared.

The above list of some of the problems that are easy to occur in the sales process, I hope to help your procurement, in the era of almost meager profits, manufacturers should rely on open source and reduce expenditure, integrate resources and rational use of talents to reduce production costs, rather than carefully designing traps to earn benefits.

The era of profiteering of cable trays is over, and whoever does not understand this will be eliminated first in the new round of competition.

Usually large cable tray manufacturers will produce galvanized trunking.

The cable tray is the surface treatment is electroplating color zinc, and the chassis is flushed with heat holes.

However, when you buy cable tray manufacturers, you need to pay attention to whether the cable tray manufacturer has a manufacturing license, and does not need a 3C certification certificate, and the cable tray is a special equipment, and the license needs to be issued by the State Quality Supervision Bureau.

At present, under the influence of fierce market competition, the brand has become an extremely valuable thing at this stage, and the cable tray manufacturer with the legal trademark of the brand is selected. Because cable tray manufacturers with legal trademark brands can not only maintain market competitiveness and recognition, but also strictly control product quality.

Usually the models of cable tray are divided into: trough type, tray type, ladder type.

The different materials of the cable tray are divided into: galvanized tray, stainless steel 304 tray, aluminum alloy 1060 tray.

The surface treatment process is divided into: fireproof baking paint, electrostatic spraying, hot-dip galvanizing (hot-dip galvanizing) Common specifications are: (width * height * thickness is: national standard thickness).

300mm*100mm*

400mm*100mm*

500mm*100mm*

600mm*200mm*
