What is NYY Cable? Where is it used? What does it stands for? The wire that is designed and used in order to transmit the electric current in the most efficient way and covered with an insulating material is called a cable. There are many different types of cables on the market, depending on their intended use and area. It is aimed to have minimum power loss during the transmission of electrical energy from one point to another. For this, it is possible to define single or multi-core conductors produced in various types and properties as insulated or bare electrical connection elements. Cables are produced by considering environmental factors such as underground, liquid contact, variable air temperature, mobile or fixed use. To be used for power, communication and control, there are protective layers and cables surrounding the conductors so that environmental and electrical effects do not adversely affect the electrical transmission.
What is NYY Cable? Where is it used? What What does it stands for? Cables can be classified as copper conductor cables and aluminum conductor cables according to the type of materials used in their production. Copper and aluminum are mostly used as conductors to make power cables more cost-effective. Although cables can be classified as weak current cables and high current cables according to their purpose of use, NYY cables, which are one of the most frequently used cable types recently, can also be defined as PVC insulated low voltage power cables.
As a result of the rapid developments in the field of technology in recent years, the cables and selection criteria of all electronic devices we use are of great importance in terms of ensuring perfect transmission in terms of human health. The selection of weak current cables is also one of the issues that should be given extreme care. Weak current cables are generally used in indoor applications, and they are generally preferred to be used in indoor applications, sound, telephone, video, alarm, data, CCTV, security systems for use below 1kV. Low voltage cables are included in weak current cables in general cable groupings.
NYY Cables Have a Wide Area of Use
NYY cables are expected to have certain characteristics, depending on their usage area and purpose. Especially in semi-intelligent and smart buildings, cinemas, schools, airports, hospitals, theaters, shopping malls, factories, tunnels and similar places where people are densely located or where valuables are located, such as not transmitting flame, low smoke density, not containing corrosive and harmful gas. Due to its characteristics, the use of NYY cables is often preferred. In addition to these, if there are risks such as impact, strain, rodent presence in the environment, it is very important for the performance of the cable to decide whether to choose the right sheath or whether there is a need for armoring. Cables may need to have various protective properties against elements such as oil, moisture and chemicals in the environment. If there is another signal in the environment that may affect the signal to be transmitted, the need for shielding may occur. Shielding types should also be determined by people who have the necessary experience and competence, depending on the environment and the characteristics of the signal. In order for the shielding to be of the desired quality, it is extremely important to pay attention to the mesh closure rates.
There are different types of NYY cables, which is a low voltage cable. NYY cables, which can be produced as single-core cables up to 1.5 – 10 square millimeters and as multi-strands up to 10 – 300 square millimeters in single core types, are insulated with an insulating sheath and then an outer sheath is placed on them. It is known that NYY cables are single-wire up to 10 square millimeters in 2-4 core types, and multi-wire in cross-sections larger than 10 square millimeters. There is a common sheath on the twisted cores of NYY cables and a black outer sheath on it.
The permissible operating temperature for NYY cables is 70 degrees, while the short-device temperature is 160 degrees. In NYY cable types with a test voltage of 2 kV and a minimum laying temperature of -5 degrees, the highest conductor temperature is 700 C and the rated voltage is 0.6 / 1kV.
Although NYY cables are similar to NYM cables in some respects, NYM cables can only be used in surface-mounted installations. It is also possible to lay NYY cables under the ground. It should not be forgotten that NYY single core cables should not be passed through the steel pipe in cases where there is more than one. Otherwise, it is possible to melt the insulation by making a capacitor effect in a very short time.
Single core NYY cables are actually cables with an insulating sheath outside. NYY cables can be used easily in areas where there is not much mechanical stress. Since they have a temperature resistant structure, they can be used very easily in application areas where there is no mechanical stress, in energy stations, network lighting, building interior installations, indoor facilities as public construction cables, cable ducts, industrial facilities, pipes and pipes.
NYY cables can be used as energy cables underground, outdoors and indoors, in fresh water, cable channels, underground, power plants, switchgear facilities, power plants and salt water if they are specially manufactured. However, it should not be overlooked that the appropriate variety should be preferred according to the usage area and purpose.
