The low-smoke halogen-free flame retardant power lines commonly used in our daily life are WDZ-BYJ, WDZ-BYJR, WDZ-RYJ, WDZ-RYJS, WDZ-RYY, WDZ-RYYP, etc. Different types of wires are used in different environmental occasions. Today, Tianxing cable will give you a popularization of the application of WDZ-BYJ wire.


BYJ wire is divided into: flame retardant type, fire resistant type, low smoke halogen-free type.

ZR-BYJ flame retardant wire

NH-BYJ refractory wire

WDZ-BYJ low smoke halogen-free flame retardant wire

The full name of WDZ-BYJ wire is copper core crosslinked polyethylene insulated low smoke halogen-free flame retardant cloth wire.

WDZ-BYJ low smoke halogen-free flame retardant wire characteristics

Suitable for conventional household voltages of 450/750V. However, the long-term allowable working temperature of the wire conductor is generally not more than 90 ° C, and the working temperature of the wire conductor does not exceed 250 ° C when the short circuit occurs, and the duration does not exceed 5 seconds.

The working temperature of the ordinary wire conductor does not exceed 70 degrees Celsius, so this kind of wire has good heat resistance, and also has the characteristics of pressure resistance, chemical resistance, radiation resistance, resistance to resistance, long life and so on.


WDZ-BYJ low smoke halogen-free flame retardant wire use

The WDZ-BYJ wire is suitable for the transmission of electrical energy in power lines with AC of 50 Hz. For example, subways, high-rise buildings, shopping malls, schools, residential buildings, etc., have high requirements for the flame retardant characteristics of wires and the environmental protection of the surrounding environment.

In addition to good safety and environmental protection characteristics, this wire also has excellent mechanical and physical properties, good environmental stress cracking resistance and wear resistance, and can withstand concentrated mechanical stress better than PVC and PE.

WDZ-BYJ is an environmentally friendly wire, which is supported and favored by the majority of users
