Q:Maintenance-free battery also need maintenance, how to maintain?

Do not need maintenance, up to the loss of electricity when the charge on the line

Q:Can the black and white sandwich be made of oil? Can the granules be made?

Not necessarily, usually in a cabinet inside, in order to manage the convenience is usually separate.

Q:Is there a replacement for high-voltage cable clamps for aluminum alloy cable clamps?

No relationship, generally in the wall of the wire is to light or switch, the power is not very small heat, only pay attention to the future wall nail.

Q:& Gt; how should the electronic truck scale sensor change?

In accordance with the general principles of calculation, 1.5mm ?? multi-strand soft copper wire can be safely through the 10A current, if the line is very long, it would be discounted ~ on the wattage, this should be based on the use of voltage level, that is 220V , About 2.5KW, 380V, then, can carry about 5KW ~

Q:What are the advantages of the ABB216RU6316RU6416RU6 connector? Ask the great god to help

There is a row of flat cable from the machine room along the hoistway wall connected to the bottom of the elevator car, which includes the elevator floor selection, car circuit within the signal line, car, car top power and walkie-talkie signal line. Generally, as long as the transparent sightseeing elevator can see the flat cable

Q:How does the generator outlet bus connection? Is it hard to connect with copper, or soft connection?

A total of six pcb are more than six layers of accessories are better than non-public version of the super better

Q:20 tons of double beam traffic acceptance standards and content which

Its advantages are: good conductivity after welding, resistance coefficient is very low or near zero; welding time is short, without any flux, gas, solder

Q:The battery of the liberation truck is poorly connected. Burned out (change very fine very fine. Battery column card is not prison) can repair it? More

Note: . control cables, variable frequency cables and other communication cable to pay attention to signal interference, to take the necessary classification or shielding measures; . the cable shall not be laid in the ditch or easy to water within the trench; . cable laying should pay attention to hidden engineering interference, such as buried water pipes or trachea. . cable laying should pay attention to beauty, try not to bend, the minimum bending radius of less than 30 to 40 times the cable diameter. . in addition to high temperature cable cable laying, do not close to high temperature objects, to keep the ambient temperature at 45 degrees Celsius for the best;

Q:Insulation puncture clip in the trunk cable puncture, the need for cable production cable head and puncture clip more

The use of shielded single-line effect than the two-line better, but the price is too expensive, the project is generally not the choice of instrumentation cable, mainly anti-electromagnetic interference and line resistance signal (line resistance too large will have a great impact on instrument accuracy, because 2-wire instrument signal and power supply is the same line) 24VDC within 1000 meters, the instrument cable with 0.75 can, of course, the greater the effect theoretically the better, but too much price too outrageous, construction is not good to do so 1000 meters is 0. more than 1 to 1.5

Q:Fast? The The The The The The The The The The The The The The The The The The The The The The The The The The The The More

You can look at their South Bridge and North Bridge. The number of capacitors and his thickness. And chipsets and more.
