Q:Do not have a very professional, can mark the specific layout, specifications can be

Transfer test Note: in the high-pressure test equipment and high voltage around the lead, should be installed to block and hang warning signs When conducting a high voltage test, the operator and the high voltage circuit should have sufficient safety distance after the end of the high-pressure test, the DC test equipment and large capacitance of the equipment to be tested multiple discharge, discharge time of at least 1min or more Where the absorption ratio of less than 12 of the motor, should first dry and then exchange pressure test circuit breaker AC voltage test should be in the sub-closing state were carried out separately In addition to the complete installation of the factory, the insulation equipment should be separated from each other to do DC voltage, the test voltage 05 times the rated voltage per stage increased in stages, each phase to stay 1min, and record the leakage current

Q:Due to the environment is not good, the original buried cable damage many times, want to use the bridge, but the overhead conditions are not allowed, the picture below is the hot water pipe, the above is the hot oil pipeline, but also over three doors more

See what you take, if it is mobile hard disk, the general mobile hard disk above have a separate power supply interface, buy a power on the line. And your USB extension cable is the kind of Y-type, two USB jacks should be inserted into the computer's USB interface above. Other U disk class power consumption is very small, there are printers or something, these devices must have a separate power supply. do not worry.

Q:How the bridge slot is connected to the ladder

Changhong TV picture-in-picture function in the remote control has a picture-in-picture dedicated button area, this area a total of eight buttons, picture in the picture to cancel the key in the CH- on the right, in the picture in the state and then click the button Is to cancel the picture in the picture.

Q:Single-core cable on the bridge why the buzzing

When the current is too large will have a magnetic field, when placed near the metal body, it may produce 50HZ AC sound.

Q:Steel cable bridge installation, how far a boom

Cable bridge standard JB-T-2000 only said that the support hanger selected materials should be consistent with their own relevant provisions; various types of hanger should be able to withstand the appropriate specifications (layers) tray, ladder rated uniform Load, meet the strength, stiffness and stability requirements. The ratio of the maximum deflection value of the cross brackets or side brackets of the steel hanger to the rated load shall not exceed 1/100 of the length of the hanger itself. Arm for the aluminum, it should not be greater than 1/150. Normal 2 meters, but also design 1.5 meters, or 1 meter.

Q:There is no fireproof bridge in the cable tray

The trough cable tray is a fully enclosed cable tray that is best suited for laying computer cables, communication cables, thermocouple cables and other high-sensitivity control cables, etc. It controls cable interference and heavy corridor Protection is better

Q:Electrical engineering bridge; two sets of cable bridge in the same height parallel laying, during which the net distance should be at least the number of centimeters. Thank you hurry

A large number of removal sets to repair the quota, a small amount of sets of installation quotas, artificial and mechanical costs multiplied by 0.. auxiliary materials, in the fixed machine tool to delete.

Q:What is the minimum distance between the lighting cable bridge and the weak bridge construction?

5 interface (headphone jack size Ji muscle irrigation can kill Jiu ghost snow Handan grinding) turn 3 lotus interface

Q:Hello to ask a question, high pressure (10KV) bridge and weak bridge can be installed with a horizontal horizontal installation

Charging with a charger is full of dissatisfaction, your battery has a monitor, then the display becomes green on it.

Q:Bridge of the jumper no less than the number of square meters, and repeat the ground not less than the number of points

Electric lighting works like this, the power into the line to the main switch (which includes the meter). This section of the line requires a separate trunking, and then by the total switch branch several switch circuit, which several inside the loop; lighting circuit room 1 loop is a trunking. The room 2 loop is a trunking, the room 3 loop is a trunking, etc., the socket circuit . . they can share the same trunking wiring. for reference only.
