4. Application area
I: Power transmission and distribution system: The series of high voltage cables are widely used in power transmission and distribution systems of 35KV and below, and are used for the construction of power transmission in urban and rural power grids, distribution lines, substates and other facilities. Its good insulation performance and mechanical strength can ensure the stable and reliable operation of the power system.
II: Power supply in industrial and mining enterprises: In factories, mines and other industrial occasions,ZR-YJV cables are widely used in high voltage power supply lines to provide safe and stable power for all kinds of production equipment and power systems. Its flame retardant property can effectively prevent the spread of fire and improve safety in case of fire.
III: Offshore engineering: The cable is suitable for the construction of power lines for offshore wind farms, submarine pipelines and other offshore engineering projects. Its resistance to seawater corrosion and moisture ensures long-term reliable operation of the cable in harsh marine environment.
5. Feature
I: Flame retardant performance: This series of cable adopts flame retardant sheath, which can effectively prevent the cable from spreading rapidly in case of fire. Even in high temperature environment, the cable will not burn easily, thus ensuring the safety of use.
II: Mechanical strength: The cable adopts steel belt or metal sheath as mechanical sheath, which has high tensile strength, extrusion resistance and impact resistance. These features greatly improve the resistance to damage during installation and operation of the cable.
III: Waterproof: THE sheath layer of this series of cables is made of high-density polyethylene material, which has excellent waterproof and moisture-proof performance. Even in humid environment, it can effectively block moisture from entering the cable and ensure the stability of electrical performance.
IV: Corrosion resistance: The metal layer and sheath material of the cable can effectively resist the corrosion of soil and chemical substances, ensuring that the cable can be used in harsh environments such as underground and ocean for a long time.
