Product Description

Product Description

1. Product Definition: ZR-YJV22 8.7/15KV 3*50 is a flame-retardant power cable with cross-linked polyethylene insulation, steel tape armoring, and polyvinyl chloride sheath. It is suitable for power transmission and distribution systems with an alternating current rated voltage of 8.7/15KV and below.

1. Structure Description

• • Conductor: Made of high-purity copper conductors, with 3 cores and a nominal cross-sectional area of 50 square millimeters per core. It has excellent electrical conductivity, which can effectively reduce line losses and ensure the high efficiency of power transmission.

• • Insulation: Cross-linked polyethylene insulation material has a high insulation resistance and electric strength, can withstand high operating voltages, and also has good thermal stability and mechanical properties to ensure the reliability of the cable during long-term operation.

• • Inner Sheath: The polyvinyl chloride inner sheath protects the insulated wire cores, preventing the insulation layer from being damaged by external mechanical forces and chemical erosion.

• • Armoring Layer: Double-layer steel tape armoring enhances the mechanical strength of the cable, enabling it to withstand large pulling forces and pressures. It is suitable for various laying methods such as direct burial and pipe threading.

• • Outer Sheath: The polyvinyl chloride outer sheath has good weather resistance, corrosion resistance, and waterproof performance, and can adapt to various harsh environmental conditions.

1. Performance Characteristics

• • Flame-retardant Performance: It has good flame-retardant properties. In case of a fire, it can effectively prevent the spread of flames, reduce the harm of fire accidents, and protect the safety of people and property.

• • Electrical Performance: With excellent insulation performance and low dielectric loss, it ensures stable power transmission, reduces power losses, and improves power supply quality.

• • Mechanical Performance: The steel tape armoring endows the cable with good mechanical properties, enabling it to resist external damage and extend the service life of the cable.

• • Environmental Adaptability: The weather resistance and corrosion resistance of the outer sheath enable the cable to work normally under different environmental temperatures, humidities, and chemical corrosion conditions.

1. Application Scenarios

• • Urban Power Grid Construction: Suitable for overhead, underground, and cable trench laying in urban medium-voltage distribution networks, providing a reliable guarantee for urban power supply.

• • Industrial Plants: It can be used for power transmission within factories, meeting the power needs of various industrial equipment and adapting to the complex working conditions of industrial environments.

• • Commercial Buildings: As the medium-voltage power inlet cable for commercial buildings, it ensures the stable power supply of shopping malls, office buildings, and other places.

Product Parameters

1. Electrical Parameters

• • Rated Voltage: 8.7/15KV, which indicates the designed voltage level for the cable to operate stably. It can withstand the normal working voltage within this range and has a certain voltage - withstanding margin for possible voltage fluctuations in the power grid.

• • Conductor DC Resistance: At 20°C, the maximum DC resistance of each 50 - square - millimeter copper core is no more than 0.387Ω/km. This low resistance value ensures that the power loss during the transmission process is minimized, improving the efficiency of power transmission.

• • Insulation Resistance: The insulation resistance of the cable is not less than 5000MΩ·km at 20°C. High insulation resistance effectively prevents leakage current, ensuring the safety and reliability of power transmission.

• • Dielectric Loss Tangent: The dielectric loss tangent (tanδ) of the cross - linked polyethylene insulation at 20°C and 1kHz is not more than 0.004. A low dielectric loss tangent means that the cable has low energy consumption during operation, reducing unnecessary power losses.

1. Mechanical Parameters

• • Tensile Strength: The cable can withstand a certain tensile force during installation and operation. The minimum tensile strength that the 3 - core cable can endure is designed to meet the requirements of practical engineering, generally not less than [X] N. This ensures that the cable will not be damaged due to pulling forces during installation or under the influence of external mechanical forces during operation.

• • Bending Radius: The minimum bending radius of the cable during installation is 12 times the outer diameter of the cable. This parameter is crucial for installation, as improper bending can damage the internal structure of the cable, affecting its electrical and mechanical properties.

1. Physical Parameters

• • Outer Diameter: The outer diameter of the ZR - YJV22 8.7/15KV 3*50 cable is approximately [Y] mm, which is determined by the size of the conductor, insulation layer, inner sheath, armoring layer, and outer sheath. This size parameter is important for cable routing and selection of installation accessories.

• • Weight: The approximate weight of the cable per unit length is [Z] kg/km. This parameter is relevant for transportation, storage, and installation cost calculations.

1. Environmental Parameters

• • Operating Temperature Range: The cable can operate normally in the temperature range from - 20°C to + 90°C. The insulation material and outer sheath are designed to maintain their performance within this temperature range, ensuring the stable operation of the cable in different climates.

• • Flame - retardant Grade: It meets the relevant flame - retardant standards, such as [specific flame - retardant standard name]. This ensures that in case of a fire, the cable can effectively prevent the spread of flames and reduce the risk of fire - related disasters.

Our Advantages

 

 

 

Before making cables, the selection of copper materials is of utmost importance. The copper materials we choose are all 99.99% oxygen-free copper rods.

Before production, conduct a circular inspection of the equipment to ensure that the probability of problems occurring at the production end is 0%.

Professional production equipment and strict requirements for product quality are our lifelines.

Conduct self-inspection during production, spot check by batch, and conduct ex-factory inspection after leaving the factory. Conduct product production supervision in strict accordance with steps that far exceed the ISO 9001 quality control standard.

Ultra-large-scale inventory is also one of our advantages

Not only do we have cables and wires. We are a group company. Under the company, there is a power design institute, a power installation company, a production plant for power distribution boxes and cabinets, a production plant for cable trays and cable accessories, and a production plant for cable conduits. We can provide integrated services from design and research to products and then to construction. If you have any power-related issues, we welcome you to discuss with us. We will do our best to provide a solution. And these services are permanently free of charge!!!
