Wire and cable designations primarily consist of model number, specification, and standard number. Because of this, there are numerous abbreviations for different cable types, and even professionals may not recognize them all. Furthermore, the designation of cable and wire models can sometimes be inconsistent. Today, we'll discuss the correct model number for flame-retardant wire, its characteristics, and its intended use.
The correct model number for flame-retardant wire is ZR - Flame Retardant.
For details, refer to the model number printed on the cable or wire sheath. Generally speaking, those with a "z" are flame-retardant, while those with an "n" are flame-retardant. Irradiated flame-retardant wire appears denser and feels different than ordinary wire. Irradiated flame-retardant wire has a smooth, fine feel and appears stronger. It also has a higher current-carrying capacity than ordinary wire. It is environmentally friendly, safe, and has a long lifespan.
About Flame-Retardant Wire
Suitable for plastic-insulated power cables with AC rated voltages up to 110 kV, plastic-insulated control cables up to 450/750 V, electrical equipment up to 450/750 V, and wires used in any application, particularly high-temperature, flammable, and existing fire-resistant types, as well as power transmission and distribution, control, alarm, and fire protection system production lines.
Features
1. Products with different rated voltages are available in: A. 06/1 kV, B. 8.7/10 kV, C. 450/750 V, and D. 300/500 V.
2. Depending on the product type, the conductor operating temperature is 70°C, 90°C, and 105°C, respectively.
3. For a short period (5 seconds), the allowable bearing temperature of the sliding contact line must not exceed 160°C and 250°C.
The above is the basic information about flame-retardant wire. It can be seen that its excellent performance brings great practicality. Therefore, it is very important to use different wires and cables in different places according to their different performance. For example, it is best to use this type of wire in some residential areas. In this way, if the wires burn, the harm can be reduced.
