0.6/1kv, XLPE Insulated PVC/PE sheathed Power cable

 

For XLPE insulated power cable ,either chemical method or physical method is employer to transform the molecular structure of PE form chain into three-dimensional network, i.e. thermoplastic PE is transformer into thermosetting XLPE. After cross-linking, the thermal and mechanical properties of PE have been greatly improved while its excellent property are still retained.

The maximum permissible operating temperature of the conductor of a XLPE insulated power cable is 90 which is higher than that of paper, PVC or PE insulated power cable. The cable has the advantage of simplicity in construction, lightness in weight, convenience in application  besides its excellent electrical, thermal ,mechanical and antichemical corrosion properties. It can also be laid with  no limitation of level difference along the route.

 

Standard

The product is manufactured according to the standard of GB12706 or IEC,BS,DIN and ICEA upon request.

 

Applications

The product  is suitable for use in power distribution lines or fixed installations  with rated power frequency voltage up to and including  0.6/1kV

 

Operating characteristics

1, Rated power-frequency voltage Uo/U : 0.6/1kV

2,Max.permissible continuous operating temperature of conductor: 90

3,Max.short-circuit temperature of the conductor shall not exceed 250.(5s maximum duration ).

4,The ambient temperature under installation should not below 0

5, The bending radius of a cable should not less than 15 times of the cable diameter.

 

Voltage designation

The rated voltage of the cable for a given application shall be suitable for the operating conditions in the system in which the cable is used , and is expressed in the form of Uo/U (Um)KV .Where :

UoThe rated powerfrequency voltage between conductor and earth or metallic scieen ,for which the cable designed;

U-The rated power-frequency voltage between conductors, for which the cable designed;

Um-The maximum value of the highest system voltagefor which the equipment may be used

Due to the circumstances of the question .. at any time questioned us
Q:Will the two 16 square copper wire with what specifications of the trunking
How to say that interference is certainly some, if you line less words on one or two in the bridge next to do a tube it! The pipe will be a little better. Upstairs that I do not think that although in practice the construction of this practice a lot, because you do not feel the interference, but the reality does interfere with, or science should not be strong and weak must be separated.
Q:Why does the AC welding machine burn out the equipment?
Cable bridge spray to improve the corrosion resistance and anti-aging. Spraying the cable tray is the electrostatic powder coating equipment to spray the powder coating to the surface of the bridge, under static electricity, the powder coating will be evenly adsorbed on the surface of the cable bridge to form a powder coating, powder coating layer through the high temperature baking flow Flat and cured, into the effect of different (different types of powder coating effect) the final coating. Spraying effect in mechanical strength, adhesion, corrosion resistance, aging resistance and other aspects are better than the painting process, the bridge body metal can play a good protective effect, the cost is also under the same effect of paint. The basic principle of electrostatic spray technology is the static generator to produce negative high pressure (10KV or so), the use of corona discharge phenomenon powder coating (a variety of colors) adsorption on the metal parts, powder coating by the supply system by compressed air Nozzle, the front end of the nozzle with a high voltage generated by the high voltage static generator, due to corona discharge, in the vicinity of the dense charge generated by the powder from the nozzle when the formation of charged paint particles, it is the role of electrostatic force , Is adsorbed to the metal parts up, after heating the powder melting, and natural cooling curing, in the workpiece surface to form a hard coating. This kind of spray cable tray is made of this.

Inverter special cable General power cable difference shielding requirements higher, the number of cores is generally 3 +. three lines of the ground line of three symmetrical and phase line intersection. Variable-frequency (VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. The inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on. The inverter will adjust the voltage and frequency of the output power by the breaking of the internal IGBT, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition, the inverter has a lot of protection , Such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, the inverter has also been a very wide range of applications.
Q:What kind of material should be selected for the fixing bracket of the cable trunking
General 2.5 square wire load is 2 kilowatts, and rubber sheathed cable, full load can reach 3 kilowatts are no problem (estimated again, it is not safe). The load level of the wire is mainly dependent on the current, but also on the voltage level. Under normal circumstances 50A below 1 square millimeter safe carrying capacity is 6A, 50 ~ 100A current 1 square millimeter of the safe carrying capacity is 5A, 100A current above the general take 1 square millimeter of the safe current is 2.5A; so many large square copper cable You can calculate the current. According to the three-phase alternating current formula: P = 1.732 * U * I * cosφ, cosφ is the power factor, select 0.8; this is the three-phase power calculation formula. Single phase: P = U * I * cosφ, cosφ is the power factor The power factor is 1 for the resistive load and 0.8 for the inductive load.
Q:What is the role of patch panels generally, why should the switch connected?
Customers want what you should have, others do not you should have. Shop to people-oriented.
Q:Wire inside the two lines, red and black, black line is the line of fire or zero line ah?
According to the size of the product to open a good plastic mold and then purchase the plastic raw materials to be injected (raw materials depending on your product requirements, advanced point will use To the engineering plastics PE, PS, etc, and even to join the flame retardant, fiber material), the difference is like now with the charger on the use of only PVC3 Called the wire manufacturers according to your request to do a good line Of course, you have the conditions you can pull the wire of their own beer process: mold on the machine (ingredients test mode) --- welding wire and hardware (pin) --- then put the welding hardware on the mold (according to the mold Put five to ten range) - boot molding - detection of another: If you want to have all the country's certification, it is estimated that you no technology is not too, you can not buy that hundreds of thousands of equipment to detect The power line in the material composition and a variety of techniques to wear flattened Fenbao match platinum standard, because the formal power It is too much to be recognized, but you want to do ordinary DC line, such as mobile phone charger or no problem, but the regular factory what automation machine to do, then I do not know, but it is automated machine estimates But also the cost of scary Anyway, ordinary manufacturers do have any questions can EMAIL: qingxinghe@21cncom Do not call me in Google, I rarely said so much, add points to me, huh, huh
