Detailed Product Description

1.VDE,UL,CCC,ROHS,CE ,IEC certificate &standard
2. PVC/XLPE sheathed Cable.
3.China top ten cable
                               

                                                                1.Applications of this power cable conductor.
Conductor (AAC and ACSR) have been widely used in power transmission lines with various voltage levels, because they have such good characteristics as simple structure, convenient installation and maintenance, low cost large transmission capacity. And they are also suitable for laying across rivers valleys and the places where special geographical features exist.
2.Service Performance
(1).The permissible long-time operating temperature for aerial conductor is 70oC.
(2).Under the circumstance that rare climate is occurring and ice coverage rate low in heavy ice area,the biggest stress of cable at the lowest point of the sag should not exceed 60% of the short-time destructive power.
(3).When connecting conductors,the conductor beside the connecting tube cant be prominent.Otherwise,the force on the operating conductors will be unbalanced.After connectors are install,the connecting tube should be painted by moisture-proof varnish in order to protect it from corrosion.
(4).Under installaion,the arc downing stress of all the conductors should be the same.With in the permissible distance of crossing buildings or dropping to the ground,the stress can be 10-15% higher than regular stress.3.Product Performance
(1).The electrical performance of AAC and ACSR is indicated in DCΩ/km(20oC).The resistivity of the hard aluminum wire for stranded wires is not greater than 28.264 nΩ. m of international standard value.
(2).The rated tensile strength of AAC is denoted with the result of total cross-section of all aluminum conductors multiplied by min.tensile of corresponding size specified in the standard for aluminum wire.
(3).The rated tensile strengh of ACSR is denoted with sum of all aluminum conductorstensile strength and steels tensile strength.
a.The tensile strength of all aluminum conductors is denoted with the result of all cross-sections of aluminum conductors multiplied by min.tensile strength of corresponding size specified in the standard for aluminum wire.
b.The tensile strength of all steel wire is denoted with the result of all cross-sections of steel wires multiplied by the stress at 1% elongation of corresponding size specified in the standard for steel wire.
4.Material Standard
(1).The hard aluminum conductor used for AAC and ACSR conforms to the standard GB/T 17048-1997(equivalent to IEC 60889:1987).(2).The zinc coated steel wire used for ACSR conforms to IEC 60888:1987.
(3).Production can be arranged according to customers requirements for material standard,etc.

Q:What is the role of patch panels generally, why should the switch connected?
The middle do not have to deal with, but also buried directly, deep 70cm, sand cover brick. It is difficult to repair, but economical and economical land.
Q:Yjv22 cable laying pipe when the casing with plastic or steel pipe
(4 × 185 + 1 × 95) is the cable specifications, indicating that the cable has 5 cores, of which 4 cores are 185 Square millimeters, one core is 95 square millimeters. General 185 line is the main core, power with, 95 for the ground core, ground use.
Q:Engineering materials inspection, all types of cable wires should be issued a test report?
Buy a distributor on the line, the computer city generally have
Q:What is the meaning of "cable tray: 200 * 100 middle strip" in electrical engineering
Two should be phase line, generally in the three-phase loop corresponding to the color: A phase is yellow, B phase green, C phase red, neutral (that is, zero line) for the blue. If only in the single-phase loop only red and green when the default is red for the phase line, green for the zero line. But not necessarily, some electricians do not follow the requirements, the specific you have to use the pen to know what the
Q:Calculate the control cable under what circumstances the cable terminal needs to be calculated
You say is the power supply power? Is not the power supply voltage! Power supply is W, that is, tile. Power power is insufficient, it is said that the components will accelerate the aging, aging components are easy to burn, components on the motherboard, of course, is burning the motherboard Oh, and power supply is also easy to cause computer instability. Crash, restart .... and so on. If your power is not enough power, it should be for a larger power and is guaranteed quality power such as Hunt, the Great Wall and so on. General 250-300W power supply on it.
Q:Fourth, what causes the power cable fire accident
After the cable is burned out, the repair time is long and the loss is serious
Q:A sub-eight splitter, behind the link ONU equipment, which also need to add fiber patch panels, or can be directly connected?
Cabinets Half Week + Line (Horizontal + Vertical) + End Range Cabinets Half Week Long or Longer to Equipment Reserve + Quota Total Length * 2.5%
Q:How to convert the computer's audio and video to cable TV signals. Through the cable television transmission to the 40 TV (hurry)
The first is to buy a computer connected to the TV dedicated audio and video lines, length specifications are: 1.8 meters, 5 meters, 10 meters, 15 meters and 20 meters, etc., everywhere sold here do not do a detailed introduction to the first step: , S-terminal video cable connection S plug the end of the line into the video on the S terminal port, while the other end of the S-terminal line into the TV behind the S terminal port, the connection is completed (Figure 1); if you You can use the "S-AV adapter" supplied by OUR to connect the S-terminal connector to the S-terminal cable, and then insert the AV head of the other head into the AV video input after the TV Mouth, the connection is completed (Figure 2). . the audio cable connection will be the audio line of the two Lotus head were inserted into the TV after the left and right channel audio input port, while the audio cable 3.5mm audio head into the audio card audio output port, the connection is completed. If you need to use the "one sub-two audio frequency line", then its 3.5mm audio head into the audio card audio output port, speakers (headphones) and audio lines were inserted into the "one two audio frequency line" 3.5 Encyclopedia of Germany, Germany and Germany Bao Bao mother on the mouth, the connection is completed
Q:The living room to the bedroom cable does not work
It is the audio cable connection is not good, you check the line and the machine at both ends of the socket is rusty, for the new line can be. In addition, the TV volume will be reduced, the set-top box volume can be filled!
Q:How to connect the power cable pre-branch connector
Pre-branch cable should be fully cooled before the plate can be installed, otherwise it will cause the connection flat, affecting the appearance of packaging should pay attention to branch and trunk The end of the seal, to prevent the core of the water
