Question:

Paint trunking, galvanized trunking: that good? expensive? Their advantages and disadvantages?

NH-YJV-4 * 4 in NH-YJV-4 * 4 in power cable tube

Answer:

6 points 1 inch equals 10 points 1 inch equals 3.3 cm 1 minute equals 0.33 mm
There are four kinds of lines are then connected to the S terminal line terminal line D AV Cable There wherein component color line terminal S and AV Cable used on PSP2000 machine models the XMB output only able to listen to music and video player can not play Delays Shanghai Gan high wet die for splashing simulation games and armpit homebrew terminal D line in the high definition television generally have much use is the most common color components of the line connector 2 are 5 audio support three video lines by able to run all games and homebrew on line scan TV (provided that set - external display settings - select progressive scan mode) If the TV does not support progressive scan, and it can only S-Video and AV terminals as well, so before use Please determine whether the TV supports progressive scan PSP3000 host no more than the above restrictions can use all the features now on the market to sell the line is generally divided into original and assembled, the effect is similar in use, in addition to the D terminal, because it is high-end line, so few assembled, prices are more expensive, probably about more than 500 pieces, AVS component cable original price of the basic recommendations are between 240-360 basic components are assembled in line to buy 30 Around a lot to find on Taobao reputable sellers use effect is good to see you choose which of
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.
