Product Description:

Conductivity

    T
he conductivity of the aluminum alloy is 61.5% of the most commonly used reference materials copper, IACS current carrying capacity is 79% of the copper, is better than pure aluminum standard. However, in the same volume, the actual weight of the aluminum alloy is about one-third of the copper. According to this calculation, the premise meet the same conductive properties, for the same weight, aluminum cable length is twice that of the copper cable. Therefore, for the same current carrying capacity,its weight of aluminum cable is about half of the copper. Aluminum cable instead of copper can reduce the weight of the cable, and reduce installation costs, reduce the wear and tear of equipment and make installation easier.

Creep Resistance

    
The alloy material and the annealing process, for the aluminum alloy conductor, reduces the tendency to creep of the conductor under the heat and pressure, compared to pure aluminum,the creep resistance is increased by 300%.

Tensile Strength and Elongation

    For a
luminum alloy conductor,compared to pure aluminum conductor, using a special process, and added a special ingredient, greatly improves the tensile strength and elongation increased to 30%, the use of more secure and reliable.

Coefficient of Thermal Expansion

    
The thermal expansion coefficient is used to calculate the size of the material changes when the temperature changes. To a thermal expansion coefficient of aluminum alloy and copper, aluminum connector have been reliably used for copper and aluminum conductors over the years, and the majority of electrical connector in use today are made of aluminum,which is particularly suitable for aluminum alloy. Therefore, the expansion and contraction of the aluminum alloy conductor,is completely consistent with the connector.

Connectivity

    
Electrical connection, for use aluminum alloy or copper,they both are security and stability. Aluminum alloy composition has been greatly improved for connection performance, even in overload and overheating for a long time,and it is able to ensure a stable connection, when the conductor annealing, creep resistance, high strength iron added.

Weight Bearing Capacity

    
Aluminum alloy has greatly improve the tensile strength compared to pure aluminum, aluminum alloy cable can support the dead weight of a length of 4000 m, copper cable can only support 2750 m. The advantages in the construction of large span (such as sports stadiums) and wiring are reflected particularly prominent.

Corrosion Protection

    
Aluminum inherent corrosion protection performance is produced from when the aluminum surface in contact with air to form a thin solid oxide layer, the oxide layer, especially to withstand various forms of corrosion.Because of rare earth elements added to the alloy ,and it can further improve the corrosion resistance of an aluminum alloy, especially electrochemical corrosion. The aluminum can withstand the harsh environment and it is widely used in the tray inner conductors of the cable, as well as many industrial components and containers. Generation of corrosion is usually associated with the connection of different metals in a humid environment,if it can be used the corresponding protective measures to prevent the occurrence of corrosion, such as the use of lubricants, anti-oxidants and the protective coating. Alkaline soil, and some types of acidic soil environment is more corrosive to aluminum, aluminum conductors for direct burial, insulation layer or molded sheath  should be used to prevent corrosion. Aluminum alloy, anti-corrosive sulfur in the environment, such as railway tunnels and other similar places, much better than copper.

Flexibility

    
Aluminum alloy with good bending performance, it has unique alloy formulation, processing technology, the flexibility to be substantially increased. Aluminum alloy is 30% higher than the copper flexibility, rebound 40% lower than copper. Usually copper bending radius of an outer diameter of 10 to 20 times, and the bending radius of the aluminum alloy cable is only 7 times the outer diameter,it is much easier for the terminal connections.

Pressed Characteristics

    
Considering single volume conductivity less than copper,for aluminium alloy conductor, we have developed not only from the material properties to have made improvements, but also to achieve a major breaking through in the technological aspects, we adopt unconventional pressed tightly technology, so pressed coefficient reached 0.93,but the profiled aliuminium alloy conductor wire pressed coefficient can reach 0.95, leading process technology in China. Maximum limit of pressed, can make up for the lack of aluminum alloy in the bulk conductivity, stranded conductor wire core similiar to solid conductor in general, significantly reducing the outer diameter of the wire core, improve conductivity,outside diameter for equivalent ampacity conductors is only 10% larger than copper.

Armored Characteristics

    
Most of the commonly steel tape armored cable,its security level is lower, its resilience by external destructive easily lead to the breakdown, and heavier, very high installation costs, poor corrosion resistance, life is shorter. Based on US standard,Mingda developed aluminium alloy interlock armored cable, the use of aluminum alloy with interlock armored  between its layers and layers of interlock structure, to ensure that the cable can withstand powerful destructive force from outside, even if the cable is subjected to greater pressure and impact, the cable is not ocurred breakdown, to improve the safety performance. Structure of interlock armored cable is isolated,if fire happened, armor layer is abble to  improve the  cable refractory level,to reduce the fire risk coefficient. Aluminum alloy with a sheathed structure compared to the steel tape armored, it is lighter in weight and convenient laying for free tray installation, and also installation costs can be reduced by 20% to 40%. Customer can choose the use of different outer sheath based on different places , to make more extensive use of armored cable.

Flame-retardant Performance

    
Excellent conductor performance is just one of its cable insulation with flame retardant silane crosslinked polyethylene, to achieve different levels of flame-retardant depending on the requirements , flame retardant  FT4 level, along burning fuel not dripping, burning LSZH, greatly improve the use of security level. Cable with aluminum alloy  armored interlock structure and LSZH polyolefin sheath can withstand 750℃ to 800 ℃, 40min of flame,it does not occur along the burning and dripping phenomenon, and can continue to supply power, its flame-retardant performance has reach retardant IA-class standards.

Q:when you hook up a resistor to a power capacitor should it be at the end of the power cable?
call radio shack
Q:acer aspire 5520g flashing lights, goes to battery power when power cable is plugged in?
How old is the laptop? Send it back now!!! Get yer money back! I've had an Acer laptop and my mate has two! All of them very, very problematic! Acers look not bad on paper (specs etc) but they are nothing but garbage! I HATE ACER!!!!! They shouldn't be allowed to sell the crap that they do!!!!
Q:How do power-station-cable thieves manage to get away without being electrocuted?
Police are hunting for a badly scorched would-be copper thief after finding a hacksaw embedded in an 11,000 volt power cable. The thief also left a lit blow torch at the scene. He is presumed to be badly charred, and not the brightest bulb in the socket. .
Q:power supply cable question?
A computer power supply is really several supplies in the same box. The specs will tell you if those 4-pin connectors all go to the same place. The outputs for the graphics card come from a different source than those 4-pin Molex connectors so those aren't going to affect performance. You would have to add up the current draw for all of the fans and the drives to know if the power supply is being overloaded. The fans have the current draw printed on them so write them down and add them up. But if you are paranoid, open the case and disconnect the case fans. Also disconnect the drives you aren't using. SSD's don't draw nearly as much power as a HDD so try to disconnect the hard drive if you can. Then run the test again and it should be exactly the same.
Q:What does the cable ZR-YJV22-4 * 16 mean?
Copper core flame retardant XLPE insulated PVC sheathed power cable, three core, 6 square
Q:what are the types of cables used in computer power supply, communication between system and its peripherals?
For communication between devices in the computer, such as the hard drive and the motherboard, either IDE or SATA cables are used. For power, Its either a 3 or 4-pin power connector, though some things have two pins (like fan connections to the mother board). Also, the SATA devices use SATA power cables.
Q:Yjv22 cable laying pipe when the casing with plastic or steel pipe
First, this should be based on specific circumstances, single-core and multi-core is the main difference between the different softness of the wire. In fact the two do not exist which good question, but the use of the environment is not the same. Second, the family decoration: . the lighting line, can be used 1.5 single strand copper wire. More than . 2P (including) more than air conditioning, that is, hot water heater, Yuba must use 4 square double strand copper wire; . the wall buried the best choice for single wire copper wire, according to the need to choose 4 square Mm, 2.5 square millimeters, 1.5 square millimeters and other specifications.
Q:what are the 2 cables for on a sata drive?
One cable is the power cable and one is the data cable, just like IDE drives have two cables for the same purpose. You will need to have a 4-pin molex to SATA power cable connector and also a hard drive controller card with a SATA port on it for you to be able to connect the drive. If you don't have both of these, you won'e be able to hook up the drive at all.
Q:Laptop Power cables Dell M1730?
i okorder.com... so best you call up dell service / support and ask them use your xps premium services to full effect
Q:xbox 1 red light on my xbox not when power cable is in the light comes on when i add the av cable to the 360 ?
My friend,Dats a damn Problem Which Makes the xbox suck... that is the most frequent problem on the x box 360.. do all the lights go Red... If all The lights Go red...It means That there is a problem with the av cable..()1st light. ( ) 2nd light... 3rd light ( ) 4th light... if the 4th light is red..it means that there is an hardware problem if the 1st and the third light are Red...it means that its overheating... if the 1st 3rd and 4th light are on...it means that there is a general hardware failure... if all the lights are on it means there is an av cable problem In ur case i think there is an problem with the av cable..
