Product Description

 

Product Description

I. Voltage Rating

 

• Meaning of Rated Voltage: The rated voltage of this cable is marked as 8.7/15KV. The "8.7" in the numerator represents the effective value of the phase voltage of the cable as 8.7 kilovolts, and the "15" in the denominator indicates that the effective value of the line voltage is 15 kilovolts. In a three-phase power system, the line voltage is usually about √3 times the phase voltage. The rated voltage setting of 8.7/15KV conforms to this voltage relationship and is applicable to specific medium-voltage power transmission scenarios, capable of meeting the power transmission requirements for a certain distance and power scale.
• Scope of Application: The voltage rating of 8.7/15KV places it in the medium-voltage category and can be widely used in various fields such as industries, commercial establishments, and infrastructure that require medium-voltage power supply. For example, in factories, it can provide stable power transmission for large production equipment, power workshops, etc.; in commercial complexes, it can meet the power demand of power equipment such as air-conditioning systems, elevators, and fire-fighting equipment; in urban infrastructure construction, it can be used for power distribution between substations and distribution boxes.

II. Conductor

 

• Characteristics of Aluminum Conductor: Aluminum is used as the conductor material, and aluminum has many advantages. Firstly, the density of aluminum is relatively small, approximately one-third that of copper. This makes the weight of an aluminum conductor cable significantly lighter than that of a copper conductor cable under the same length and conductivity requirements, which is extremely advantageous for easier handling and installation during the laying process, especially for some occasions where long-distance laying or weight requirements are involved (such as less load pressure on towers during overhead laying). Secondly, the raw material cost of aluminum is much lower than that of copper, which can effectively reduce the overall procurement cost of cables in large-scale power projects.
• Conductor Structure: The aluminum conductor is usually formed by twisting multiple strands of aluminum wires together. This multi-strand twisted structure endows the conductor with good flexibility, enabling it to easily bypass various obstacles such as pipe corners and tower supports during the laying process without being easily broken or damaged. Meanwhile, the multi-strand twisting also increases the conductive cross-sectional area of the conductor, improving the overall conductivity, and the mutual support between the multiple strands enhances the mechanical strength of the conductor, enabling it to better withstand mechanical forces such as tension and pressure that may be encountered during the operation process.

III. Insulation Layer

 

• Advantages of XLPE Insulation: Cross-linked polyethylene (XLPE) as an insulating material has excellent properties. In terms of insulation performance, XLPE has an extremely high resistivity, which can effectively prevent the leakage of current from the conductor to the surrounding environment, ensuring the safety and efficiency of power transmission and minimizing power loss. Its dielectric constant is relatively stable and can maintain a good insulation effect under different electric field intensities and frequency conditions.
• Temperature Resistance Performance: The XLPE insulation layer has outstanding temperature resistance characteristics and can work within a wide temperature range. Generally, the temperature range it can withstand ranges from minus tens of degrees Celsius in low temperature to over ninety degrees Celsius in high temperature or even higher (depending on the product quality standard). In a high-temperature environment, it will not experience softening, deformation and other situations that lead to a decline in insulation performance like some ordinary insulating materials, thus ensuring the reliable operation of the cable in hot summer or high-temperature industrial environments; in a low-temperature environment, it will not become brittle and fragile either, and can still maintain good insulation and mechanical protection performance, which is suitable for power transmission applications in cold regions.
• Mechanical Properties: Besides insulation and temperature resistance performance, XLPE also has good mechanical properties. It has a certain tensile strength and compressive strength, which enables it to withstand external mechanical forces such as squeezing and stretching. When the cable is subjected to such forces, the XLPE insulation can act as a buffer, protecting the internal conductor from damage while maintaining its own integrity without cracking or experiencing insulation layer degradation, thereby ensuring the overall stability and service life of the cable.

IV. Inner Sheath

 

• Function of PVC Inner Sheath: The inner sheath is made of polyvinyl chloride (PVC) material, and PVC plays an important protective role here. From the perspective of insulation, it provides additional insulation protection for the XLPE insulation layer, forming a double-layer insulation guarantee, further reducing the risk of current leakage and enhancing the overall insulation performance of the cable.
• Corrosion Resistance Performance: PVC has good corrosion resistance and can resist the erosion of various chemical substances from the external environment, such as acid-base gases and chemical solutions that may exist in some industrial sites. When the cable is laid through these areas where corrosion sources may exist, the PVC inner sheath can effectively isolate these corrosive substances, preventing them from directly contacting the XLPE insulation layer, thus protecting the integrity of the insulation layer and avoiding power transmission failures caused by a decline in insulation performance due to corrosion.
• Mechanical Protection: Meanwhile, the PVC inner sheath also provides a certain mechanical protection for the insulation layer. It can prevent the insulation layer from being slightly mechanically damaged during the cable laying process, such as scratches and bumps, as well as potential mechanical hazards caused by environmental factors during the operation process (such as friction of soil particles, accidental collisions with other objects, etc.), maintaining the good state of the insulation layer and ensuring the normal operation of the cable.

V. Armouring Layer

 

• Principle of Steel Tape Armouring: The armouring layer adopts the method of steel tape armouring. The steel tapes are usually made of high-strength steel and are wound around the outer layer of the cable through specific processing techniques. This armouring structure can provide powerful mechanical protection for the cable. When the cable is subjected to external mechanical forces such as squeezing and collision, the steel tapes can bear and disperse these forces, preventing them from directly acting on the key components such as the insulation layer and conductor inside the cable, thus avoiding damage to the internal structure of the cable.
• Tensile Resistance Performance: The steel tape armouring also significantly enhances the tensile strength of the cable. In some application scenarios where the cable needs to bear a certain tensile force, such as when the cable is laid overhead and needs to bear its own weight and the tensile force that may be generated by wind load, or when the cable is laid underground and needs to be pulled through some pipes, tunnels, etc., the steel tape armouring can ensure that the cable will not break or have its internal structure deformed due to excessive tensile force, ensuring the normal laying and operation of the cable.
• Protection Effect: In addition, the steel tape armouring also improves the anti-puncture ability of the cable to a certain extent. In some complex environments, such as underground where there may be sharp stones, metal foreign objects, etc., the steel tapes can prevent these sharp objects from piercing the cable, protecting each component inside the cable and maintaining the integrity and functionality of the cable.

VI. Outer Sheath

 

• Function of PVC Outer Sheath: The outer sheath is also made of polyvinyl chloride (PVC) material, which provides comprehensive external protection for the cable. From the perspective of resisting environmental factors, the PVC outer sheath can effectively prevent the intrusion of moisture. If moisture enters the cable interior, it may cause the insulation layer to get wet, which will then seriously affect the insulation performance and trigger power transmission failures. The PVC outer sheath can form a barrier to block the moisture outside the cable, ensuring the normal operation of the cable in humid environments such as underground laying and outdoor humid climates.
• UV Resistance Performance: It also has a certain UV resistance ability. For cables laid outdoors, long-term exposure to sunlight will cause certain damages to the outer sheath and internal components of the cable, such as causing the outer sheath to age, change color, become brittle, etc., which will then affect the overall performance of the cable. The PVC outer sheath can absorb and reflect a part of the UV rays, slowing down the erosion speed of the UV rays on the cable and prolonging the service life of the cable.
• Flame Retardant Performance: In addition, the PVC outer sheath usually has a certain flame retardant performance. In some places where fires may occur, such as industrial plants, commercial buildings, etc., once a fire breaks out, if the cable does not have flame retardant performance, it may become a medium for the spread of the fire, exacerbating the danger degree  of the fire. When encountering a fire source, the PVC outer sheath can to a certain extent prevent the spread of the fire, reducing the harm of the fire to the cable itself, as well as the surrounding equipment and personnel, and improving the safety performance of the cable.

VII. Application Scenarios

 

• Industrial Field: In the industrial environment, this cable is widely used. For example, in various factories, it can be used for power transmission between transformers and distribution cabinets, ensuring that large production equipment (such as machine tools, punching machines, injection molding machines, etc.) can stably obtain medium-voltage power supply. In special industrial sites such as steel mills and chemical plants, due to the complex environment with multiple adverse factors such as high temperature, corrosion, and mechanical impact, the cable with the structure of 8.7/15KV aluminum conductor XLPE insulation can well adapt to and ensure the reliability of power transmission.
• Commercial Field: In commercial complexes, shopping centers, and office buildings, this cable can be used to provide power for power equipment such as air-conditioning systems, elevators, and fire-fighting equipment. These equipment have high requirements for the stability and safety of power supply, and the cable's properties, such as its reliable insulation and mechanical protection, meet these requirements, ensuring the normal operation of commercial establishments.
• Mining Field: In the mining process, the mining environment is harsh, with problems such as rock squeezing, groundwater erosion, and dust pollution. The 8.7/15KV aluminum conductor XLPE insulation steel tape armoured cable can be used to provide power for underground ventilation equipment, drainage equipment, and mining equipment. Its armouring structure can resist the squeezing of rocks and the piercing of sharp objects, and the insulation layer and sheath can prevent the erosion of groundwater and the dust of pollution, ensuring the stable and reliable power supply of underground equipment.
• Tunnel Field: In tunnel engineering, whether it is a highway tunnel, a railway tunnel, or an urban underground tunnel, this cable can be used to provide power for lighting equipment, ventilation equipment, and monitoring equipment. The tunnel environment is relatively closed, with high requirements for fire prevention, moisture prevention, and mechanical protection of cables. The cable's PVC outer sheath with flame retardant performance, waterproof performance, and the steel tape armouring with mechanical protection performance can meet these requirements, ensuring the normal power supply and operation of the equipment in the tunnel.
