Why medium voltage power cable sometimes write 8.7 / 10kv sometimes written in 8.7 / 15kv where the difference

Answer:

1 audio and video line of the problem (red and white) to connect the TV box set-top box that line to the cable or radio equipment store to buy a definite muscle wings can be Jiu sad snow on the line 2 TV bad to find TV manufacturers
. 1.8.7 / 10kV U value of 10KV, which can withstand the maximum voltage of 12KV8.7 / 15kV U value of 15KV, which can withstand the maximum voltage of 17.5KV2.8.7 / 10kV is 10KV system in the first Class II cable (fault time can be greater than 1 minute) 8.7 / 15kV is the first type of cable in the 15KV system (failure time is not more than 1 minute) 3.U0 / UU0 - conductor and insulation shield between the voltage U - the The voltage between the conductors is two, the cable is usually a few or several groups of wires [at least two] stranded from the rope similar to the cable, each group of wires insulated from each other, and often around a central twist The entire outer package has a highly insulated cover. Multiple in the air or in the ground, underwater, for telecommunications or power transmission.
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: Do not call me in Google, I rarely said so much, add points to me, huh, huh
If you buried the VGA line core has more than 7 (set the exclusion of the moxibustion smoked smoked ship to remove the shield), you can. VGA head is 5 to 10 feet welded together to do the public, red, green, blue shielded wire twisted together to receive the public ground: ..3 feet connected red, green, blue core; ; 14 white lines; outer shield pressure to the shell. (At least two) at both ends to pick out the audio line (left and right channels), shield to do the public, to access the audio 3.5 straight plug. If only one rich, on the channel to listen to listen to mona channel it
