Calcium-aluminum alloy cable tray is made of glass fiber reinforced plastic, flame retardants, and other materials, which is pressed through composite molding compound with stainless steel shielding mesh. The selected materials have low thermal conductivity and the addition of flame retardants makes the product not only have fire resistance, thermal insulation, and self-extinguishing properties, but also high corrosion resistance. At the same time, it also has advantages such as light structure, not easy to age, safe and reliable, and can be conveniently used in conjunction with metal cable trays.
The installation of calcium-aluminum alloy cable trays can be adapted to local conditions. It can be laid overhead along with the process pipelines of aluminum alloy cable trays; suspended from floors and beams; installed on indoor and outdoor walls, and also can be installed on outdoor columns or piers. When large multi-layer cable trays are hoisted, it should be laid symmetrically on both sides of the I-beam column as much as possible. Calcium-aluminum alloy cable trays can be laid horizontally and vertically, can have corner turns, cross-shaped branches; can be adjusted in width, height, and diameter. Cable trays are widely used in our lives. There are also many types of cable trays we commonly see, and the properties and quality of each cable tray are different. So how should we distinguish the quality of cable trays?
1. Appearance of calcium-aluminum alloy wire and cable
Whether there is a quality system certification certificate, whether there is a qualification certificate, certificates can also be forged. When checking, be sure to look carefully to see if it is very standardized.
2. Hand feel of calcium-aluminum alloy wire and cable
Gently slide your hand over the wire and cable to see if there is a scratching feeling. If the hand feel is soft and the elasticity is relatively large, it indicates that the quality of the wire and cable is very good, and you can buy it with confidence.
3. Color of calcium-aluminum alloy wire and cable
Cable tray manufacturer introduces that generally, if the copper core is yellow with a slight red tint, it indicates that the raw copper material used is of good quality. If the copper core appears purple-black, it indicates that there are many impurities and it is easy to break. If you are buying aluminum core wires, as long as you don't buy those that are dull and lack luster, the good quality aluminum core is bright silver-white.
4. Price of calcium-aluminum alloy wire and cable
If the above 3 points are all fine, but the price is ridiculously low, you must be careful at this time, because people are getting smarter now, and many illegal means are unimaginable. Therefore, many unscrupulous merchants sell inferior wires and cables under the guise of good quality and low price.
The above is the relevant knowledge about calcium-aluminum alloy cable trays brought to you today. Through the above introduction, I believe everyone has some understanding of how to identify the quality of wires and cables. As long as you purchase according to the above, don't be greedy for small advantages, and buy from regular manufacturers, you will definitely be able to purchase wires and cables with guaranteed quality and suitable prices.
