Q:The wall was sideways opened a trough how to do ah?
PVC pipe. Iron pipe, trunking, bridge, hose, and so on. The The PVC pipe, trunking generally the most common, used in the kind of request is not very strict, not much bit line. Capital is not high, low cost, iron pipe bridge is mainly used in fire strict buildings, shopping malls, high cost, security, line points and more use of bridge hose used in the line out of the floor to the desktop section. Nice point of the ceiling. Overhead floor, are suitable for placement is not comprehensive, personal experience
Q:What is the difference between VV22 and VV62?
Cross-linked power cable heating the main reason there are . the choice of continuous allowable current is less than the load of the maximum continuous current power cable; . the power cable in the implementation of the cable for cold contact, the use of crimping pliers die too large, leading to copper . the air switch input and output and cable copper nose connection, the choice of non-standard flat gasket or no spring gasket; . the air switch input and output side of the cable and cable core crimp is not solid and reliable; When the cable is connected to a strand, the air switch bolts are not tightened. . high-power UPS running, the filter cabinet is not put, n harmonic effects of cable overload, neutral overload, serious lead to cable breakdown, and a fire hazard. . the power cable along the building facade iron cabinet box laying, the surrounding environment is not ventilated, poor heat dissipation. Select the power cable should consider the following factors: . the rated voltage of the cable is greater than or equal to the rated power supply system power supply system; . the cable can continue to allow the current to be equal to or greater than the maximum load current load; . Power supply system short-circuit stability requirements; . according to the length of the cable to determine whether the voltage drop to meet the requirements; . the end of the line minimum short-circuit current should be able to protect the device reliable action. . a high degree of breakdown strength; . low dielectric loss; . a very high insulation resistance; . excellent resistance to discharge performance; . with a certain degree of flexibility and mechanical strength; . long-term stability of insulation.
Q:Whether high voltage cables can be built in belt corridors
When the short circuit occurs when the wire through a large current, more than the rated current of the wire, so the wire will heat
Q:What is the use of wire and cable per square meter of residential building?
You can use sc. if too long, or bend the best use of the bridge
Q:Will the computer master, external DVD burner how external power supply, please click details. Thank you!
You can shop on the ground floor of a layer of waterproof carpet (that is, the rural common 'kang seats'), the wire shop in the following, at the desk to stay a outlet hole, and the jack or electrical connection. Carpet can be bought in the hardware building materials store, as the traces of tape, you can go to the big supermarket to buy a special scrub, ask the salesman on the line. Wish you the best at work
Q:1.2 meters below the road can use pvc tube wear armor cable?
Have to fight trumpet, mainly to protect the cable jacket is not scratched
Q:What is the wiring principle in the home improvement circuit?
Section 4 "Downhole Cable" Article 466 No cable should be laid in the total return airway and the dedicated return airway
Q:TV tiger when the set-top box when tv / ay look for a look on the platform
. the first two said two cables, KW is KVV that PVC insulated jacket control cable. . the control cable for industrial and mining enterprises, energy and transportation sector, for the exchange rated voltage 450/750 volts below the control, protection lines and other occasions, the use of PVC insulated, PVC sheathed control cable. . the performance difference: the power cable in the main line of power systems used to transmit and distribute high-power power, control cable from the power system distribution point of electricity directly to a variety of electrical equipment, power equipment, power lines. The rated voltage of the power cable is generally 0.6 / 1kV and above, the control cable is mainly 450 / 750V. The same specifications of the power cable and control cable in the production, the power cable insulation and sheath thickness than the control cable thick.
Q:The difference between the instrument cable and the low voltage power cable
Silicone rubber insulated power cable blistering, stomata is caused by the process problems, silicone rubber insulated cable in the injection should be used when the vacuum casting, raw materials to fully degassed, otherwise there will be blistering and stomata, some small factories because there is no vacuum Injection equipment, coupled with poor degassing process will produce this poor product, to solve this problem is the first workshop to maintain constant temperature and humidity, the purchase of excellent performance of the vacuum injection equipment and vacuum mixing equipment, strict control of process parameters. Silicone rubber power cable for AC rated voltage 0.6 / 1KV and below fixed power transmission line or mobile electrical connection cable, the product has heat radiation, cold, acid and corrosive gases, waterproof and other characteristics, the cable structure is soft, Radiation, high temperature (alpine) environment, electrical performance and stability, anti-aging performance, long life, widely used in metallurgy, power, petrochemical, electronics, automobile manufacturing and other industries
Q:What is the length of the wire that affects voltage and electricity
When the cable is laid on the multi-layer bracket, the cables are arranged from top to bottom, the first layer is the high voltage cable, followed by the low voltage power cable. The control cable is placed on the lower part of the power cable. At the bottom of the instrument cable, when the low voltage power cable With the instrument cable in the same layer of laying, should be added partition isolation. Computer communication coaxial cable, full length are required to shield the use of closed trunking.
