What are the models of aluminum core cables?

The models of aluminum core cables are: BLV, YJLV, YJLV22, VLV, VLV22.

Introduction to copper-clad aluminum:

Copper-clad aluminum cable refers to the wire and cable with aluminum core instead of copper as the main body of the cable, and a certain proportion of copper layer is covered outside.

Classification: Copper-clad aluminum cables can be basically divided into two categories according to their uses: one is copper-clad aluminum cables for signal or communication purposes, and the other is copper-clad aluminum cables for power supply.

Advantages: The use of copper-clad aluminum conductors will play a role in reducing the AC impedance (resistance) generated by higher harmonics. In other use occasions, by taking measures to increase the volume of copper in copper-clad aluminum-clad monofilament and the corresponding technological measures, the copper-clad aluminum-copper composite conductor meets the requirements of conductor DC resistance within the upper limit of the outer diameter size of the existing conductor of the same specification.

The use of copper-clad aluminum conductor can meet the habits of wire and cable in product selection, design, use, installation and other aspects for many years, and it is also beneficial to the terminal pressing and tin welding of the cable.

Reduced AC resistance.

It has good corrosion resistance: aluminum is more corrosive than copper, but because the copper-clad aluminum material has been completely metallurgized, aluminum is completely covered by copper and will not be contacted by water and air, and completely achieves the same performance as copper.

Low cost and light weight: Compared with copper-core cables with the same technical indicators, copper-clad aluminum conductor cables can save more than 40% of costs, and copper-clad aluminum-copper composite conductor cables can save more than 20% of costs.

Good weldability: Copper-clad aluminum wire has the same solderability as pure copper wire due to its concentric surface coated with a layer of pure copper, which is convenient for production.

Aluminum core cables are basically used in power cables (not control cables), low-voltage cables (380V) basic common models are 3*6+1*4 is PVC insulated PVC sheathed aluminum core, four-core cable, main core 3 cores, each core 6 square millimeters cross-section, coring (used as a neutral wire) 1 core, 4 square millimeters cross-section.

List of aluminum cable specifications and models: BLV, YJLV, YJLV22, VLV, VLV22.

YJV-3*185+2*95, model + several times several This format indicates the number of cable cores in the first few fingers, and the second refers to the cross-sectional area of a single core; It represents a YJV cable consisting of 3 cores with a cross-section of 185 square meters and a 2-core cross-section of 95 square millimeters.

The aluminum core is denoted by the letter L. For example, single-core wire: the model of copper core is BV, the model of aluminum core is BLV, the model of copper core of multi-core wire is BVV, and the model of aluminum core is BLVV.

Copper core power cable models have VV, YJV, aluminum core power cable models have VLV, YJLV, etc.

Aluminum alloy power cable

It is a new material power cable with AA8030 series aluminum alloy material as the conductor and advanced technology such as special roll-forming profile stranding production process and annealing treatment.

Alloy power cable makes up for the lack of pure aluminum cable in the past, although the conductivity of the cable has not been improved, but the bending performance, creep resistance and corrosion resistance have been greatly improved, which can ensure that the cable maintains continuous performance stability when overloaded and overheated for a long time, and the AA-8030 series aluminum alloy conductor can greatly improve the conductivity and high temperature resistance of the aluminum alloy cable, and at the same time solve the problems of pure aluminum conductor and creep.

<>< how many models of aluminum core cables are 240.

240 aluminum core cable models are VLV-3*10+1*6, VLV-3*25+1+16, VLV-3*35+1*16, VLV-3*70+1*35, VLV-3*95+1*50, VLV-3*120+1*70, VLV3*150+1*70, VLV3*185+1*95, VLV3*240+1*120, VLV3*300+ 1*150, VLV3*400+1* 150, etc.

What do you need to consider when purchasing 240 aluminum core cables?

1. Due to the quality of wires and cables on the market, consumers should try to buy in large shopping malls and supermarkets. When choosing products, try to choose a well-known manufacturer, whose technical strength and manufacturing level are high, good reputation, and quality assurance.

2. Consumers should buy "CCC" products. Because of the certified products, the materials have been inspected, and the quality is relatively high. If you have any questions, you can also check the China Quality Certification Center or the CNCA**.

3. When purchasing cables, you should check the information of the outer packaging certificate, especially the manufacturer's address, model, voltage, etc. In addition, it is necessary to see whether the marks on the cable and wire body carry the manufacturer's name, model and voltage level, and you can also request the relevant inspection report and certificate from the dealer.

4. The appearance of the cable should be smooth and flat, and the edge layer and the cladding layer should have no obvious defects, no pinholes, no roughness, no clear identification and printing, and no greasy feeling when touching the cable by hand. If possible, check that the cross-section of the cable, the insulation and the sheath should be of the specified thickness and that there is no major eccentricity. The surface of the copper conductor shall not be oxidized to black, and the surface of the aluminum conductor shall not be oxidized to white.

Tear the insulation or sheath by hand, it must have a certain toughness and flexibility, and it is not easy to break. Sentenced to be bored.

Copper-clad aluminum-clad cables can be basically divided into two categories according to their uses: one is copper-clad aluminum-clad cables for signals or communications, and the other is copper-clad aluminum-clad cables for power supply.

Extend your data. Aluminum core cable is basically used for power cable (non-control cable), low-voltage cable (380V) basic common model is, PVC insulated PVC sheathed aluminum core, four-core cable, three main cores, each core cross-section is 6mm2, one core (used as neutral) cross-section of 4mm2.

There are five types of aluminum core cables, and now there are more cable brands, and the quality and price comparison of cables are still more optimistic about Dianli cables.

There are five types of aluminum core cables: YJLV22, VLV, VLV22, BLV, and BAYJLV.

Aluminum core cable models include BLV, YJLV, YJLV22, VLV, VLV22, etc.

The specifications and models of aluminum core cables are BLV, YJLV, YJLV22, VLV, and VLV22. Aluminum core cable generally refers to copper-clad aluminum cable, which refers to the wire and cable with aluminum core instead of copper as the main body of the cable, and a certain proportion of copper layer is wrapped outside. Copper-clad aluminum cables can be basically divided into two categories according to their uses:

One is copper-clad aluminum-clad cables for signal or communication purposes, and the other is copper-clad aluminum-clad cables for power supply.

The resistivity of copper-clad aluminum wire is larger than that of pure copper wire, about times that of pure copper wire, and when the negative value is the same, the weight of copper-clad aluminum wire is about 1 2 of pure copper wire. According to the calculation of the skin effect, the resistivity of the high frequency above 5MHz is equal compared with that of copper conductors of the same cross-section.

The use of copper-clad aluminum conductors will play a role in reducing the AC impedance (resistance) generated by higher harmonics. In other use occasions, by taking the technological measures of increasing the volume of copper in copper-clad aluminum-clad monofilament and corresponding rolling, the copper-clad aluminum-copper composite conductor meets the requirements of conductor DC resistance within the upper limit of the outer diameter size of the existing conductor of the same specification.

Although copper-clad aluminum-clad cable has been born and is gradually being applied, there is still a lot of resistance, mainly because it is difficult to find the application basis of copper-clad aluminum-clad cable in the country and industry, and it is difficult to be recognized by the design unit.
