Description

Features

1) Fire resistance: NH-YJV cables have excellent fire resistance and can withstand high-temperature combustion environments for up to 90 minutes. This characteristic enables NH-YJV cables to maintain power transmission during fires, ensuring the stable operation of critical systems.

2) Electrical and Mechanical Properties: NH-YJV cables use XLPE insulation and PVC sheath, which not only have good electrical properties such as high insulation resistance and low dielectric loss, but also excellent mechanical strength and heat resistance. The long-term allowable operating temperature of the cable conductor varies depending on the model, usually 70°C, 90°C, or 105°C.
