Q:Yjv22 cable laying pipe when the casing with plastic or steel pipe
In the air defense regulations, the pipelines of the air defense zone need to be treated with the protective wing ring. The bridge frame is designed according to the cable laid in the bridge. The cable size and quantity determine the size and quantity of the casing. Increase the standby, air defense requirements casing with hot galvanized treatment, both sides of the exposed wall shall not be less than 100 mm, wing ring production can refer to rigid waterproof casing or flexible waterproof casing (explosion-proof). The general construction plans will have a clear sign, or should be presented to the Design Institute in the trial.
Q:How to identify the quality of the lock of the hotel lock?
PE cable that waterproof cable can be a short time to soak the water PE water pipe is used to transmit water to the water pipe than the requirements of the drainage pipe than the cable all PE high hardness
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:110 voice patch panel directly to the telephone line can be connected to it
sure. Take the ground pipe is to be from the floor under the brick. But the late completion of the drawing to be accurate, so that the next time to repair the line can not find the location. Want to answer to help you.
Q:Apple mobile phone does not support this charge when charging this thing how to charge
Can not! "Power Cable Design Code" Article 5.1.3 provides that the number of stents by the channel space constraints, 35kV and about the adjacent voltage level of power cables, can be arranged in the same layer of stent. 10kV power cable (actually 8.7 / 10kV) and 380V power cable (actually 0.6 / 1kV) in the interval between the 6kV and 3KV two voltage levels, not the adjacent voltage level, can not!
Q:Fourth, what causes the power cable fire accident
Once the cable in the event of fire, the fire ferocious, rapid spread, in the burning will occur when a large number of harmful gases, resulting in fighting difficulties
Q:TV tiger when the set-top box when tv / ay look for a look on the platform
Do not have to be so troublesome, such a phenomenon even encountered, is the basement of the air defense, similar to the landlord said the phenomenon can be taken as follows: . first with linen live wire and casing blank. . filled with asbestos cement and compaction, the surface concave sleeve 3-4 cm. . with plugging the king (5 yuan / bag) add water and mix well, smear the surface to smooth. . the work is completed, do not hurt the core and the practice proved no leakage within two years.
Q:Power cable yjv22-10kv-3 * 50 what it means
Yj is cross-linked polyethylene insulation, v PVC sheathed 22 is double steel tape armored, voltage 10KV, 50 square three-core copper cable
Q:How to find the phone number on the 110 patch panel
Cable ends should be marked with cable head symbols, the middle line should also be different from the ordinary wiring. Bv at the beginning of the general wire, with YJV or vv is generally a cable, but not limited to these
Q:How to determine whether the square of the cable is standard
Depends on your number is not arranged in order, the general building room when the patch panel and the user board number is one to one correspondence
