How to choose the quality of the bridge?

The first thing to understand is that the raw materials for the consumption of the bridge are mainly insulation materials, electrolytic copper, and sheath materials. The quality of the bridge is largely determined by the raw materials. When choosing the quality of the bridge, pay attention to the following points:

1.The color of the bridge

People in the industry have introduced that the reddishness of the common copper core yellow indicates that the raw material copper used is of excellent quality, and the copper core is purple black, indicating that there are more impurities and it is easy to break. If you buy an aluminum core wire, you don't need to buy the dull and dull, the good quality aluminum core is bright snow white.

2, the appearance of the bridge

Whether the appearance can have a quality system certification, whether there is a certificate of conformity, and the certificate can be forged. When you check it, you must take it seriously and check whether it is standard. Whether the basic information such as trademarks, specifications, and voltages are complete, and those with incomplete basic information must not be purchased. For the sake of insurance, unpack the outer layer and see if the bridge maintenance insulation layer can be lubricated and damaged.

3.The price of the bridge

The price is ridiculously low. At this time, you must be careful. As people are getting smarter today, many unscrupulous wrists can hardly imagine it, so many unscrupulous merchants sell cheap wires and cables under the guise of good quality and low price.

4, bridge feel

Glide quietly on the bridge with your hands, with or without scratching, how to feel soft and flexible, which demonstrates that the quality of the bridge is excellent and can be purchased.

How should the bridge be accepted?

1. Is the type, standard and quantity of the bridge common with the order form, and whether the fastening accessories are accurate?

It will be more useful to perform inspections based on these constructs, but, together, we need to pay attention to these inspection details:

2. It is necessary for the type, standard and quantity of the bridge to be common with the purchase order. The raw materials and thickness should meet the request. Usually, when the bridge width is more than 300mm, the thickness of the steel plate is 1.5mm, and when the bridge width is 300mm or more, the thickness of the steel plate is greater than or equal to 2mm. The thickness of the connecting plate is the same as that of the bridge.

3. Assemble the on-site assembly of linear grooves, components, etc. to check whether the joints are uniform and not greater than 1mm.

4. Is the type, standard, and quantity of the bridge parts common with the order form, including the direction of the zigzag part and the orientation of the bridge cover, etc.?

5. The fire receipt of the fire protection request should be within the useful period to ensure that the quality of the fire protection product is qualified and reliable.

6. Is there any mechanical damage to all linear grooves, components, and hanging brackets? Is the anticorrosion of the metal raw materials uniform, intact, not flowing, and bottomless?

7. Is the bridge connecting plate and fastening accessories accurate?

How to select the quality of the bridge and how to accept it have been introduced in detail above. If you want to know more, please pay attention to the news on our official website mytckj.com.
