Widely Use:

Industrial production: YJQ cables are favored for their good electrical properties and corrosion resistance in production lines and equipment in industries such as electricity, metallurgy, and chemical industry.

Construction field: YJQ cables also play an important role in power transmission and signal transmission systems in high-rise buildings, bridges, tunnels, and other buildings.

Transportation: YJQ cables are also commonly used in power transmission and signal transmission systems in transportation fields such as subways, light rails, and railways.

Petrochemical: Due to its excellent corrosion resistance and flame retardant properties, YJQ cables are also suitable for power transmission and signal transmission in fields such as petroleum and chemical industries.

Advantage:

Copper core conductor: High-purity oxygen-free copper is used, which has excellent conductivity, low resistance and durability, minimizing energy consumption.

Cross-linked polyethylene (XLPE) insulation: Through advanced cross-linking technology, the XLPE insulation layer has higher resistance to electric field strength, thermal aging and high temperature.

Longitudinal water-blocking design: For humid environments, special water-blocking materials and processes are used to effectively prevent moisture from diffusing along the longitudinal direction of the cable, ensuring the long-term operation stability of the cable.

Lead sheath shielding layer: The lead sheath design has excellent mechanical protection and corrosion resistance, provides good electromagnetic shielding effect, and adapts to complex industrial environments and high safety requirements.

Polyethylene outer sheath: wear-resistant, UV-resistant, and resistant to environmental stress cracking, providing additional physical protection for the cable and extending its service life.
