Product Definition and Characteristics
Definition: WDZA - BYJR (F) is a high-performance wire product. "WDZA" reflects its key properties, namely low smoke (Low - Smoke), halogen-free (Halogen - Free), flame-retardant (Flame - Retardant) with a flame-retardant grade of A. "BYJR (F)" illustrates the structure and material composition of the wire, including building wire (B), polyethylene (Y) insulation, cross-linked (J), flexible wire (R), and possible special functions (F).
Environmental Protection Characteristics:
1.Halogen-Free Advantage: The halogen-free feature is an important environmental protection symbol of this product. Traditional wires will release harmful gases containing halogens (such as chlorine, bromine, etc.) when burning. These gases not only cause serious irritation and harm to the human respiratory system and eyes but also corrode surrounding equipment and building structures. However, WDZA - BYJR (F) wires are halogen-free and can greatly reduce the generation of toxic and harmful gases in the event of a fire, providing a relatively healthy environment for personnel escape and fire rescue.
2.Low Smoke Performance: The low smoke performance is also one of its outstanding features. Under burning conditions, it generates very little smoke, and the smoke concentration can be significantly reduced compared with ordinary wires. This is because the product has been optimized in terms of material formulation and manufacturing process, so that smoke generation is effectively controlled. In a fire scene, clear visibility is crucial for the safe evacuation of personnel. The low smoke characteristic can ensure that people have more time to escape from the dangerous area before it is filled with smoke, and it is also beneficial for firefighters to find the fire source and carry out fire extinguishing work more quickly.
II. Structural Features
Conductor Part: As the core of the wire, the quality of the conductor directly affects the conductive performance of the wire. WDZA - BYJR (F) wires usually adopt high-quality metal materials, such as high-purity copper or copper alloys. Such materials have good electrical conductivity and can effectively reduce power loss during power transmission. For example, during power transmission, compared with some materials with poor electrical conductivity, it can make the current pass more smoothly and improve energy utilization efficiency.
Its flexible characteristic (indicated by "R" for flexible wire) makes it easy to bend and install, enabling it to adapt to various complex wiring environments. Whether in a narrow space or in a wiring layout scenario that requires frequent bending, such as the connection of electrical equipment inside buildings and the internal wiring of electrical appliances, it can play its advantages.
Insulation Layer: The insulation layer is mainly made of polyethylene (Y) material and has undergone cross-linking (J) treatment. Cross-linked polyethylene has excellent insulation performance and can effectively isolate the conductor from the external environment, preventing current leakage and electric shock accidents. For example, in a humid environment, this insulation layer can prevent moisture from contacting the conductor and ensure the safe operation of the electrical system.
This insulation layer also has good heat resistance. This is because the cross-linked structure enables the material to maintain stable performance in a high-temperature environment. During normal use, even if the temperature around the wire rises, such as when it is close to heating equipment, it will not be easily deformed or damaged, thus ensuring the long-term reliability of the wire.
III. Performance Advantages
Flame Retardant Performance: The characteristic of a flame-retardant grade of A enables WDZA - BYJR (F) wires to effectively prevent the spread of flames in the event of a fire. Through special material formulations and manufacturing processes, when encountering a fire source, it can form a charred layer. This charred layer can play a role in isolating flames and heat, slowing down the speed at which the fire spreads along the wire. For example, in a building electrical system, if a wire catches fire, using this flame-retardant wire can prevent the fire from spreading rapidly to other areas, buying precious time for firefighters' fire extinguishing work and personnel evacuation.
Electrical Performance: Due to the adoption of high-quality conductors and good insulation materials, this wire has excellent electrical performance. It can stably transmit current and maintain a good working state under different voltages and frequencies. In the connection of various electrical equipment, it can ensure the efficient transmission of electrical energy and reduce voltage drop and power loss caused by wire quality problems. For example, in an industrial automation control system, this wire can provide a stable power supply for precise instruments and equipment and ensure the normal operation of the system.
Durability: From a long-term use perspective, WDZA - BYJR (F) wires have good durability. The stability of its structure and materials enables it to resist the erosion of environmental factors, such as humidity, chemicals, and temperature changes. In an outdoor environment, it can withstand the test of sun and rain, and in an indoor environment, it can also cope with various possible pollution and temperature fluctuations. This durability can not only extend the service life of the wire but also reduce the costs and inconveniences caused by frequent wire replacement.
IV. Application Fields
Construction Industry: It is widely used in the electrical systems of various buildings, such as residential buildings, commercial buildings, and public buildings. For lighting circuits, socket circuits, and power supply circuits of various electrical appliances, its low smoke, halogen-free, and flame-retardant characteristics can provide reliable safety guarantees for the personnel and property in the buildings. In densely populated places, such as shopping malls, hotels, and hospitals, using this kind of wire can reduce the harm of smoke and toxic gases in the event of a fire and improve the efficiency of personnel evacuation.
Rail Transit Field: Stations, carriages, and other places in rail transit have extremely high requirements for wire safety. The low smoke, halogen-free, and flame-retardant performance of WDZA - BYJR (F) wires complies with the safety standards of rail transit. When used in the wiring of electrical equipment in carriages, the lighting and signal systems of stations, etc., it can ensure that in emergency situations, such as fires or electrical failures, a large amount of smoke and toxic gases will not be generated, ensuring the life safety of passengers and the normal operation of rail transit.
Electronic Equipment and Electrical Appliance Manufacturing: In the internal wiring of electronic equipment and electrical appliances, the flexibility and good electrical performance of this wire play an important role. It can provide high-quality internal connections for computers, televisions, refrigerators, and other electrical appliances. Meanwhile, its environmental protection characteristics also meet the requirements of modern electronic products for materials, reducing the potential environmental hazards of electronic products during use and disposal.
