High Voltage YJV Cable – 8.7/15kV Copper Core Cross-Linked Polyethylene Insulated Power Cable

Product Overview:
High-voltage YJV cable is a high-quality power cable with a rated voltage of 8.7/15kV, which is made of high-quality oxygen-free copper conductor and cross-linked polyethylene (XLPE) insulation with excellent electrical properties, heat resistance and mechanical strength. It is suitable for medium and high voltage power transmission and distribution systems, widely used in urban power grids, industrial parks, substations and other occasions.
Product Features:
High electrical conductivity: adopting oxygen-free copper conductor, excellent electrical conductivity, low resistance, low power loss.
Excellent insulation performance: cross-linked polyethylene (XLPE) insulation layer, high voltage strength, stable insulation performance, low partial discharge.
High temperature resistance: long-term working temperature up to 90°C, maximum temperature up to 250°C in short circuit.
High mechanical strength: optional steel belt or steel wire armouring layer, enhancing the cable’s tensile strength and pressure resistance, suitable for complex laying environment.
Corrosion and ageing resistance: polyvinyl chloride (PVC) or polyethylene (PE) outer sheath, with good corrosion resistance and anti-aging properties, to extend the service life of the cable.
Environmental protection and safety: in line with RoHS environmental standards, non-toxic and harmless, safe and reliable to use.
Application areas:
Urban power grid: suitable for urban underground cable laying, transmission line reconstruction and so on.
Industrial field: widely used in large factories, mines, oil fields and other medium and high voltage power transmission.
Substation: applicable to substation, distribution room and other medium and high voltage power distribution system.
New energy field: it can be used for power transmission of new energy power generation projects such as wind farms and photovoltaic power stations.
Other fields: it is applicable to medium and high voltage power supply of large infrastructure such as tunnels, bridges, airports and so on.
