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
Power cable accessories are divided into several types, commonly used is heat shrink cable accessories, cold shrink cable accessories. (1KV, 10KV, 20KV, 35KV), several models (indoor, outdoor, intermediate connection), each containing the components are not the same, but there are all kinds of cold Heat shrinkable sleeve, heat shrinkable sleeve, heat shrinkable sleeve, heat shrinkable sleeve, heat shrinkable sleeve, heat shrinkable tube, sealant and other operating accessories.
Q:Copper core power cable models which several kinds
First, the total number of wire and cable products are thousands, applied in all walks of life
Q:Apple mobile phone does not support this charge when charging this thing how to charge
So, from the degree of hearing up, it is not suitable for the family pet
Q:What are the requirements for the spacing between the strong and weak wires?
DIY notebook, I recommend you look at the Jingdong Mall, where there are genuine hardware and equipment, that is just the same as the same to buy back, you have to go home to assemble it! Such as CPU, graphics cards, hard drives, processors, heat sinks, monitors and the like can be bought
Q:20 tons of double beam traffic acceptance standards and content which
This phenomenon is generally the audio input has an AC signal amplified by the amplifier after the results, supplies a little short and good quality of the input of the smooth exchange of spring spring to help Tong burst Kun line test, if not improved that is the receiver problem.
Q:Power cable casing buried what are the requirements
2 direct laying cable way, should meet the following requirements: 1 cable should be laid in the trenches, and should be along the length of the cable on the next, next to the side of the shop with a thickness of not less than 100mm soft soil or sand 2 along the length of the cable should cover the width of not less than 50mm on both sides of the cable protection board, protective board should adopt concrete 3 urban cable buried in the laying, it is appropriate in the protection board laying eye-catching signs 4 in the suburbs or open areas, along the cable path of the line spacing of 100m, corner or joint parts, should be erected obvious signs or signs 5 when the use of cable through the corrugated pipe laying in the trenches, should be along the full length of the bellows casting thickness of not less than 100mm of concrete, the width should not be less than 50mm outside the tube, the cable can not armor 3 buried in the non-frozen soil area, the cable embedding depth should meet the following requirements: 1 cable to the basement of the basement structure, not less than 03m 2 cable skin to the ground depth, not less than 07m; when located in the carriageway or farmland, should be properly deepened, and should not be less than 10m 4 buried in the permafrost area, should be buried below the permafrost layer, when not buried can be buried in the soil drainage of dry frozen soil or backfill, but also take other measures to prevent damage to the cable The 5 Directly laying the cable, is strictly prohibited in the underground pipe is just above or below The minimum distance between cable and cable, pipe, road, structure, etc shall be in accordance with Table 535 Table 535 Permissible minimum distance between cable and cable, pipe, road, structure, etc (m)
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.
