ZC-YJY23-26/35kV-3 * 185 high-voltage cable, national standard cable quantity of 162 meters, shipped every other day

It is a high-performance power cable suitable for power transmission and distribution systems. The following is a detailed introduction about ZC-YJY23-26/35kV high-voltage cable:

1、 Basic characteristics

• Model meaning：

• ZC: Indicates flame-retardant cable, Class C flame-retardant rating.

• YJY: Represents copper conductor, cross-linked polyethylene insulation, and polyethylene sheath.

• 23: Refers to steel belt armor (may not be directly reflected in the model, but understood according to conventional naming conventions).

• 26/35kV: Indicates the rated voltage level of the cable, where 26kV is the conductor to ground voltage and 35kV is the conductor to phase voltage.

• Core materialCopper wire.

• insulating materialCross linked polyethylene (XLPE) has excellent electrical and heat resistance properties.

• Sheath materialPolyethylene (PE) has good corrosion resistance and mechanical strength.

2、 Structural characteristics

• conductorMade by twisting high conductivity copper wire to ensure the current carrying capacity of the cable.

• insulating layerUsing cross-linked polyethylene material, it is cross-linked through chemical or physical methods to improve insulation performance.

• Inner protective layerPolyethylene inner protective layer plays a role in protecting the insulation layer.

• Armor layerSteel belt armor enhances the mechanical strength and resistance to external damage of the cable.

• outer sheathPolyethylene outer sheath provides additional protection and corrosion resistance.

3、 Performance advantages

• flame retardant performanceThe cable has a Class C flame retardant rating, which can effectively prevent the spread of fire in case of a fire.

• Electrical performanceExcellent insulation resistance and voltage resistance ensure the safe operation of cables under high voltage.

• mechanical propertiesSteel tape armor endows cables with excellent compressive, tensile, and impact resistance.

• Resistant to environmental stressThe cross-linked polyethylene insulation layer has good resistance to environmental stress cracking.

• Long service lifeDue to the use of high-quality materials and advanced manufacturing processes, the service life of cables is relatively long.

4、 Application scenarios

• Power transmission and distribution systemSuitable for fixed installation on AC 50Hz, rated voltage 35kV and below power transmission and distribution lines, used for transmitting electrical energy.

• industrial sectorCan be used for power supply systems in industrial and mining enterprises.

• infrastructureSuitable for power transmission in places such as tunnels, cable trenches, and pipelines.

5、 Precautions

• Installation and laying：

• The minimum bending radius of the cable should comply with relevant standards to avoid damaging the cable.

• During the laying process, mechanical damage and chemical corrosion should be avoided.

• The terminal treatment of cables should comply with relevant standards to ensure reliable electrical connections.

• Operation and Maintenance：

• Regularly check the operating status of cables, including insulation resistance, leakage current, and other parameters.

• Timely detect and handle cable faults to avoid accidents.

• Keep the cable laying environment dry and ventilated to avoid moisture and overheating.
