2,the implementation of standards
GB / T12706.1 ~ 12706.3-2008ratedvoltage1KV (UM = 1.2KV)to35KV (UM = 40.5KV)extruded insulation powercables and accessories.


3, uses
This product is suitablefor fixed installationinAC 50HZ,ratedvoltageelectricitytransmission and distributionwireson the road0.6 / 1kv-26 / 35KVfordeliveryofelectric energyuse.


4, using the properties
1) The maximumrated temperatureofPVCinsulatedcable conductor70 ℃, XLPEorEPR, HEPRinsulation90 ℃.

2)short (the longestsustained5S)conductor temperatureofPVCinsulation does not exceed160 ℃, XLPE, EPR, HEPRinsulation does not exceed250 ℃.

3)whenthe ambient temperatureof cable layingshouldnot be less than0 ℃,such aslayingbelow 0 ℃,the cable shouldpreheat,cable bendradius:

Cables should notbe less than20times the cable diameter,multi-core cableis not less than15times the cable diameter.

4)greater thanthe ratedvoltage6KVcable connectorsshould bepeeled offthe external screenabout100MM,andcleanto prevent thesemi-conductive shieldinglayeralongthe surface ofthe conductive coredischargecaused bythe breakdown, causingdelayburninginsulation, causingunnecessary accidents.

5)In thelayingprocess, shouldprevent waterandmoisture from enteringthe cable core,in order todischargewaterrust, affectingcablelife.

Q:Ipad charge does not enter the charge does not support this accessory charge
Friends, my task, hope to adopt! Answer: sorghum (Liang) explained: the poles are relatively high, beautiful riding on the poles is in the height of their own beautiful, so according to the meaning of harmony, the answer is sorghum.
Q:Wire yellow and green, respectively, that line of fire or zero line
Suggestions or online shopping it Feeling very difficult to match the silicone sleeve, the Internet is very easy to buy, about 10 yuan or so, C430. I just bought a Taipower c430 last month, did not buy silicone sets, bought a Moog MP4 package, that with a silicone sleeve machine becomes ugly. Hope to help the landlord.
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:Power cable ZRYJV-4x70 + 1x35 What does it mean?
51 laying of cables 511 cable laying should meet the following requirements: 1 cable type, specifications should be consistent with the design requirements
Q:How long is the service life of the cable?
cable bridge and other pipes and other facilities shall not share a column (bracket)
Q:30 on the large number of cable how to fight on the 110 patch panel, how to order, please inform, thank you, which
Is the size of the power cord size, that is, the thickness of the power line diameter, 4 square power cord diameter is 2.2 mm thick, the safety current between about 25-32A, that is, can withstand electrical power at 5500 watts or .000 watts Depends on the laying of the power cord, that is, the laying of dark lines or laying the line, the size of the safe current is not the same. Generally more than 2 air-conditioning use 2.5 square copper wire, 2 or more air conditioning should use 4 square copper wire.
Q:What is the fire wire pipe laying? What is the galvanized steel pipe?
Another example is the flashlight and electric shaver although the voltage is very low, power and current is very small, is still strong
Q:What are the lines that need to be set up for notebooks?
YJV cable is cross-linked polyethylene insulation, VV cable is PVC insulation, the former temperature level higher than the latter, such as the former conductor temperature can be 90 degrees, while the latter can only to 70 degrees!
Q:Paint trunking, galvanized trunking: that good? expensive? Their advantages and disadvantages?
Because the AC operation will produce eddy current, will make the steel pipe and cable heat burned. Single core refers to only one conductor in an insulating layer. When the voltage exceeds 35kV, most of the single-core cable, its core and metal shield layer relationship can be seen as a transformer primary winding coil and the relationship between the core. When the single-core cable core through the current when there will be magnetic lines linked to aluminum or metal shielding layer, so that both ends of the induced voltage. Power safety regulations: 35kV and below the voltage level of the cable are used at both ends of the grounding method, which is because most of these cables are three-core cable, in normal operation, the current flow through the three core sum of zero, in the aluminum There is no flux chain outside the package or metal shield, so that there is essentially no induced voltage at both ends of the aluminum or metal shield, so there is no induced current flowing through the aluminum or metal shield after grounding at both ends. But when the voltage exceeds 35kV, most of the single-core cable, its core and metal shield layer relationship can be seen as a transformer primary winding coil and the relationship between the core. When the single-core cable core through the current when there will be magnetic lines linked to aluminum or metal shielding layer, so that both ends of the induced voltage.
Q:What is the warranty period for wire and cable?
General cable maintenance period is about 15 years, but to ensure that the normal use of the environment, such as the amount of temperature is below 70 degrees, but you are more than 70 working environment to use, of course, may not be used for a year. Therefore, the most important thing is to follow the instructions to use. Wire and cable recommended Ogilvy's.
