Detailed Introduction to Vav Armored Cable and Steel Tap Armored Cable

In numerous fields such as power transmission, construction engineering, and industrial manufacturing, cables, as key carriers of energy and signal transmission, their performance and quality are directly related to the stable operation of the entire system. Vav Armored Cable and Steel Tap Armored Cable, as two types of high-performance armored cables, occupy an important position in the market with their respective unique advantages. The following will provide a detailed introduction to these two cables from two dimensions: the product itself and the general information of the product.

From the Perspective of the Product Itself

Specifications and Parameters

Specifications and parameters are the basis for cables to adapt to different scenarios. Both Vav Armored Cable and Steel Tap Armored Cable have a wide range of options in this regard, which can meet diversified needs.

The cross-sectional area of Vav Armored Cable covers 0.5-240mm², which almost covers various needs from small equipment connection to medium-sized power transmission. For example, in the Internal Wiring of some precision instruments, a cross-section of 0.5mm² can meet the requirements of small current transmission; while in the connection of some power equipment in industrial workshops, a cross-section of 240mm² can handle the power transmission of larger power. Its rated voltage range is 0.6/1kV to 10kV. 0.6/1kV is suitable for low-voltage distribution systems, such as the distribution lines of residential quarters and the internal power supply of small factories; 10kV can be used for medium-voltage power transmission, such as the branch transmission of urban power grids and the internal power distribution of industrial parks.

The cross-sectional area of Steel Tap Armored Cable is between 1.5-400mm². Compared with Vav Armored Cable, it has more advantages in large cross-section cables. The 400mm² cross-section enables it to carry larger currents, which is suitable for the power supply of large industrial equipment and the main distribution lines of large buildings. Its rated voltage is 0.6/1kV to 35kV. The rated voltage of 35kV allows it to be applied to higher voltage level transmission scenarios, such as power interconnection lines between cities and power output lines of large Power Stations, which can meet the diversified needs from low-voltage distribution to medium-voltage transmission.

Characteristic Applications

Different structures and performance characteristics make Vav Armored Cable and Steel Tap Armored Cable have different emphases in their characteristic applications.

Vav Armored Cable, with both Flexibility and protection, performs well in places with high requirements for cable flexibility and protection performance. In the connection of equipment in industrial workshops, since the equipment needs to be moved or adjusted frequently, the cable needs to have a certain degree of flexibility to facilitate wiring and installation. At the same time, there are many mechanical collisions and vibrations in the workshop. Vav Armored Cable can resist these mechanical damages and ensure the stable transmission of electricity. In the vertical wiring of high-rise buildings, the cable needs to extend from the bottom to the top. During the wiring process, it needs to be bent and turned. Its flexibility enables it to complete the wiring smoothly. Moreover, there are many people and equipment in high-rise buildings, and the requirements for cable protection are high. It can effectively resist the erosion of humid environments, avoid affecting the insulation performance due to moisture, and ensure the safety of power supply.

Steel Tap Armored Cable, with its strong armored structure, plays an important role in some scenarios that need to withstand large external pressures. When laid directly underground, the cable needs to bear the pressure of the soil and the rolling of ground vehicles. The strong armor of Steel Tap Armored Cable can effectively resist these external pressures and prevent the cable from being damaged. In tunnel projects, due to the limited space, the cable may be squeezed by other pipelines or collided during construction, and its armored structure can provide good protection for the cable. When erected outdoors, it can resist wind, rain, sun exposure and the impact of external objects, ensuring normal operation in harsh environments.

Material Styles

The material of the cable directly affects its performance. Both Vav Armored Cable and Steel Tap Armored Cable have been carefully considered in material selection to ensure high-quality products.

The conductors of both cables are mostly made of 99.9% high-purity electrolytic copper or high-conductivity aluminum. High-purity electrolytic copper has extremely low resistance, which can reduce energy loss during current transmission and ensure the efficiency of power transmission. At the same time, its good ductility makes the conductor not easy to break during processing, improving the reliability of the cable. Although high-conductivity aluminum has slightly lower conductivity than copper, it is lighter in weight and relatively lower in cost. It is a good choice in some scenarios where weight and cost are required, such as Overhead Lines, which can not only meet the conductivity requirements but also reduce the overall cost and installation difficulty.

The insulation layer is made of cross-linked polyethylene (XLPE) or polyvinyl chloride (PVC) with a temperature resistance of -40℃ to 105℃. Cross-linked polyethylene (XLPE) has excellent aging resistance and insulation reliability. It can maintain stable insulation performance in both high and low temperature environments. Moreover, it has good chemical stability and is not easy to be eroded by external chemicals, so it is suitable for various harsh environments. Polyvinyl chloride (PVC) has good flame retardancy and mechanical strength, and its price is relatively low. It is widely used in some scenarios with high flame retardancy requirements and relatively mild environmental conditions, such as wiring inside buildings.

The armor layer is made of hot-dip galvanized steel strip or steel wire. After special processing, the impact resistance, corrosion resistance and mechanical strength of the cable are significantly improved. Hot-dip galvanizing forms a uniform zinc layer on the surface of the steel strip or wire, which can effectively prevent the steel from being corroded and prolong the service life of the cable. Steel strip armor has good flexibility and lateral pressure resistance, and is suitable for some scenarios that need to be bent; steel wire armor has higher mechanical strength and tensile performance, and is suitable for occasions with large tensile force, such as vertical laying and underwater laying.

Production Process

Exquisite production process is the key to ensuring cable quality. Both Vav Armored Cable and Steel Tap Armored Cable strictly control every process during production.

In the conductor drawing link, precision drawing equipment is used to draw copper rods or aluminum rods. By precisely controlling the size of the drawing die and the drawing speed, the cross-sectional size of the conductor is ensured to meet the design requirements, and the surface is smooth and burr-free. This not only ensures the uniform and stable conductivity of the conductor but also reduces damage to the insulation layer in subsequent processing.

In the insulation layer extrusion process, advanced extruders are used to uniformly coat the molten cross-linked polyethylene (XLPE) or polyvinyl chloride (PVC) on the surface of the conductor. During the extrusion process, the extrusion temperature, speed and pressure are strictly controlled to ensure that the thickness of the insulation layer is uniform, without bubbles, impurities and other defects. The uniformity of the insulation layer is crucial to ensure the insulation performance of the cable, which can effectively prevent insulation breakdown caused by excessive local electric field strength.

The tight winding of the armor layer is a key step to improve the protection performance of the cable. For steel strip armor, special winding equipment is used to tightly wind the steel strip around the insulation layer at a certain angle and tension to ensure that there are no gaps between the steel strips, forming a solid protective layer. For steel wire armor, it is also necessary to precisely control the winding tension and spacing of the steel wires to make the steel wires evenly distributed and jointly bear external pressure and tension.

After each process is completed, the cable must undergo strict testing. Withstand voltage test is an important one. By applying a certain voltage and maintaining it for a period of time, check whether the insulation performance of the cable meets the standard to ensure that there will be no breakdown phenomenon under the rated voltage. Insulation resistance test measures the resistance value of the cable insulation layer to judge the quality of its insulation performance. In addition, there are many tests such as appearance inspection and size measurement. Only cables that pass all test items can leave the factory to ensure stable and reliable product quality.

From the Perspective of General Product Information

Packaging

In order to ensure that the cable is not damaged during storage and transportation, Vav Armored Cable and Steel Tap Armored Cable adopt a scientific and reasonable packaging method.

The packaging materials are a combination of moisture-proof kraft paper and galvanized iron plates, with a wrapping film covering the outer layer. Moisture-proof kraft paper has good moisture-proof performance, which can effectively block moisture in the air from entering the cable, preventing the cable from getting damp and affecting the insulation performance. The galvanized iron plate provides a solid support for the cable, which can prevent the cable from being deformed due to extrusion during transportation and storage. The outer wrapping film has good sealing and tensile properties, which can tightly combine the kraft paper and the iron plate, further enhancing the moisture-proof and pressure-proof performance of the packaging, and at the same time preventing the cable from falling off the iron plate during transportation.

For cables of different lengths and cross-sections, different specifications of galvanized iron plates are used. Cables with small cross-sections and short lengths usually use smaller iron plates, which are convenient for handling and storage; cables with large cross-sections and long lengths use larger iron plates to ensure that the cables can be neatly wound on them, avoiding distortion and knotting.

Transportation

In order to meet the needs of different customers and ensure that the cables can be delivered to the destination in a timely and safe manner, Vav Armored Cable and Steel Tap Armored Cable provide flexible and diverse transportation methods.

Whole-vehicle land transportation is supported, which is suitable for the transportation of large-volume orders. Whole-vehicle transportation can ensure that the cables are not mixed with other goods during transportation, reducing the risk of collision and extrusion, and the transportation efficiency is high, which can quickly deliver the goods. For long-distance and large-volume orders, container sea transportation is an economical choice. Containers have good sealing and protection properties, which can effectively resist wind, rain, salt spray and other erosion at sea, ensuring the quality of the cables. At the same time, the transportation cost of sea transportation is relatively low, which is suitable for long-distance transportation.

For small-volume orders, less-than-truckload distribution is a more appropriate way. Less-than-truckload distribution can concentrate small-volume goods from multiple customers for transportation, reducing transportation costs and ensuring timely delivery of goods. During transportation, the transportation plan will be optimized according to the order quantity and the specific situation of the destination, and the fastest, most economical and safest transportation route and method will be selected to ensure that the cables are delivered to customers on time and in good condition.
