A cable can burn at a high temperature of 950℃ and keep it for 3 hours without electricity;
The latest mineral cable released by GDMX Cable Technology Group, a Chinese special cable technology company, breaks through the current level of the industry, extending from one hundred meters to one kilometer… Hay Think learned the above information at a product launch held by GDMX recently.
"Deeply plowing the special cable industry for 32 years, GDMX has been technology-driven and has obtained 98 patents. It is estimated that the revenue of Minxing Cable in 2020 will increase by 20% over last year.
Over 100 million R&D investment per year
The safe use of electricity concerns thousands of households. As people's pursuit of quality of life is getting higher and higher, building construction fire protection and safety levels are getting more and more attention, and safer and environmentally friendly wire and cable products are favored by the market.
Mineral insulated cables are indispensable fire-proof cables for the backbone of modern construction projects to ensure power transmission. They can be used on power supply lines such as fire-fighting power supplies, uninterrupted power supplies, and emergency lighting power supplies.
A few days ago, as one of the earliest companies in China to develop mineral fire-resistant cables, GDMX released the company's new third-generation mineral cables.
"This product can meet the requirement of continuous combustion at 950℃ for 3 hours without electricity. Compared with the first and second generation products, magnesium oxide insulation is denser and more stable." said Hu Runyi, technical director of GDMX.
Mineral cables, because the cables are all made of inorganic materials (metallic copper and magnesium oxide powder), it will not cause fire, burn or support combustion, because the melting point of copper is 1083°C, and the mineral insulation layer is also above 1000°C. Therefore, this kind of cable can continue to maintain power supply in the event of a fire with a high temperature of 950 ℃, and has a strong fire protection function.
"Before, due to technical and stability reasons, the length of the mineral cable was basically about 100 meters. The third generation of GDMX mineral cable uses the'magnesium oxide automatic filling and continuous roll type' technology, and has the industry's leading'double welding gun 'And'double tapping' technology can achieve a cable length of up to one thousand meters, breaking the industry's original level. Moreover, the yield rate is higher and the construction and installation are easier." Hu Runyi said.
Behind the breakthrough of cable industry restrictions is the company's increased investment in technology research and development. "After years of development, we already have complete engineering and technical comprehensive supporting test conditions, and a R&D team of more than 60 people with rich experience in research and development and engineering design. Each year we invest more than 100 million yuan in research and development funds to improve product quality. Increase technological innovation.” Yang Yan said that currently, several invention patents for this mineral cable product are under application.
With the launch of the third-generation mineral insulated fireproof cable this time, GDMX’s mineral cable products have covered rigid mineral cables, flexible mineral cables, and ultra-flexible mineral cables. It has become one of the few companies in China that has the core technology of all types of mineral cables.
As early as 2016, GDMX established a national "Special Inorganic Mineral Cable Engineering Technology Center". In the past 32 years in the industry, GDMX has 98 national patents. Among them, radiation cross-linked high-end home improvement wires, mineral insulated fireproof cables and other products with core patents are at the leading level in China; it has a national CNAS certification laboratory and its testing capabilities have been authoritative Institutional and industry recognition.
