Guda Cable Group
Recently, after the examination and approval of the State Intellectual Property Office, Guda Cable Group has won three utility model patents. They are "a 1.8/3kV anti-rat power cable for wind energy, a low-voltage power cable with anti-interference, and a flexible control cable". The acquisition of this patent is another innovation on the basis of obtaining more than 40 new utility patents. It is the latest certification of Guda Cable Group's independent research and development capabilities, scientific research results and product conversion capabilities.
With the rapid development of the national economy, the application range of control cable is more and more extensive. As a cable suitable for industrial and mining enterprises, energy and transportation departments, for control of AC rated voltage below 450/750 volts, protection lines and other occasions, its performance requirements are high and the structure is complex; among them, the cable for wind turbines is mainly used in high altitude, Plague and insect pests, low temperature and other harsh environment areas. In order to overcome the existing copper strip winding process, if there are burrs on the edge of the copper strip, it is easy to pierce through the insulation and cause breakdown. Due to the air gap between the insulation and the shield, the cable may be broken down during use due to moisture and moisture. And mice and termites bite the cable to cause short circuit or open circuit, affecting the safe operation of the whole system and other problems. The "1.8/3kV anti-rat power cable for wind energy" developed and produced by Guda Cable Group not only reduces the weight of the small cable, but also improves the bending degree of the cable and greatly increases the flexibility of the cable. The armored protective layer made of non-magnetic aluminum tape effectively protects the cable from being eaten by mice and termites, and enhances the overall tensile strength and flame retardant fire resistance rating of the cable. Superior comprehensive performance, simple structure, safe and reliable, stable performance, strong practicability, suitable for popularization and application.
With the rapid development of society, people's awareness of safety and environmental protection is also increasing, and the requirements for the safety and reliability of electrical equipment and equipment are getting higher and higher. The three-phase four-wire system used for low-voltage power distribution lines has become a three-phase five-wire system. On the basis of the original system, protective grounding wires are added to the grounding of equipment to ensure that electrical equipment is less harmful to people and equipment when leakage occurs. At the same time, as the main line of the power system for the transmission and distribution of high-power power cable products, the existing power cable anti-interference effect is poor, in the signal transmission process is vulnerable to external magnetic field interference, easy to make the signal receiving end of the signal reception error, resulting in information transmission can not run normally. In response to this reality, Guda Cable Group has developed and produced "an anti-interference low-voltage power cable" through technical tackling. By setting up a multi-layer shielding layer and an armored protective layer, the anti-interference ability and tensile strength of the cable are enhanced. Secondly, the addition of filling layer, fire protection layer and sheath layer ensures that the cable has excellent flame retardant and fire resistance, greatly improves its flame retardant and fire resistance rating, and has stronger safety performance.
In view of the existing optical cable, there are processes such as cable formation, braiding and sheathing, the optical fiber attenuation is unqualified or even broken due to bending, squeezing and stretching force, thus affecting the product performance. When connecting radar equipment, it is necessary to lay and install corresponding control cables and optical cable connection ports respectively, and the engineering quantity is large. Guda Cable Group has developed and produced a kind of photoelectric composite control cable-"a kind of flexible control cable" which is suitable for radar use and can be used for multiple purposes with one cable, avoiding the problems of numerous cables in equipment, repeated installation and wiring, messy wires and difficult maintenance ". The conductor is made of several fifth tinned copper conductors specified in GB/T3956-2008, which has good stability, conductivity, wear resistance, corrosion resistance and electromagnetic shielding. The insulation layer is made of fluorine plastic, which has good dielectric strength and insulation resistance. Compared with polyethylene and polyvinyl chloride cables, which are only suitable for working environments of 70~90 degrees, fluorine plastic cables can adapt to high temperature environments of 150~200 degrees and are more resistant to high temperatures. Braiding with tin-plated conductor with aramid fiber weaving, to achieve anti-electromagnetic interference shielding, eliminate cable surface electricity, binding power lines and eliminate induced electricity; aramid wire also effectively improve the tensile strength of the cable, to prevent the cable due to bending radius is too small caused by mechanical damage.
As a national "specialized and new 'little giant'" key cultivation enterprise, Guda Cable Group has always adhered to the concept of innovation-driven development, focused on technological innovation, and continuously enhanced its independent research and development capabilities, scientific research results and product conversion capabilities to enhance the core of the enterprise Competitiveness. In the next step, Guda Cable Group will further focus on the development strategic goal of "high-end, intelligent, and green", gather high-end talents, and increase the research and development of cable products used in high-tech fields such as charging pile cables. Fully promote the enterprise to move steadily and fast on the road of high-quality development.
