Direct Burial and Multi-Purpose Use

Jiangsu Jingwei has 39 years of experience in cable manufacturing. This outdoor underground wire is a versatile product. It can be directly buried in soil, used outdoors, or installed in conduits. It covers a full range of models, including YJV, YJLV, YJV22, and YJLV22. It is available in 4-core and 5-core types, with sizes ranging from 1.5 sq mm to 400 sq mm. It is suitable for underground burial, outdoor trenches, and municipal projects.

Armoured and Unarmoured Options

The conductor is made of copper or aluminium. The XLPE insulation provides excellent resistance to heat and high voltage. Armoured types use steel tape or steel wire, allowing them to withstand soil pressure, resist rodent damage, and prevent mechanical impact. These can be directly buried without additional protection. Unarmoured types are lighter and more flexible, making them suitable for use in conduits and indoor environments. All specifications comply with IEC 60502, meeting long-term outdoor and underground application requirements.

The multi-core design helps keep wiring organized and reduces installation time. It is flame-retardant and explosion-resistant. It is suitable for use in municipal pipeline networks, residential area burial, factory power systems, street lighting, and landscaping projects. The service life can reach up to 30 years with minimal maintenance.
