Q:What is the heat of the cross-linked cable?
General model: SYV75-X (X on behalf of its insulation diameter 3mm / 5mm, the greater the larger the diameter of the larger) SYV S --- coaxial RF cable, Y --- polyethylene, V --- poly Ethylene
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:Which has, know the power of the electrical, choose the cable formulas. And explain it
Is the interference signal line can not go with the wire,
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:Ipad charge does not enter the charge does not support this accessory charge
Friends, my task, hope to adopt! Answer: sorghum (Liang) explained: the poles are relatively high, beautiful riding on the poles is in the height of their own beautiful, so according to the meaning of harmony, the answer is sorghum.
Q:Power cable inspection, how many meters should be sampled?
installation quota: cable ZR-YJV-4 * 70 + 1 * 35 is a five-core cable, you can refer to sets of "copper power cable laying cable (section mm2 below) 120? Cable "quota, and the fixed sub-sub-multiplied by the coefficient 1
Q:Power Cable Check Well b-type covers show what?
A grade steel fiber concrete inspection covers are used for airports or special roads and venues for expressways that can take off and land for helicopters
Q:20 tons of double beam traffic acceptance standards and content which
Change the data line ah, often with non-original battery will be filled with bad
Q:Wire and cable manufacturing process (to be detailed)?
Tell you an electrician commonly used "empirical formula": as long as the copper wire, cross-sectional area per square millimeter can be safely through the 4 - 5A rated current; in 220V single-phase circuit, the power per 1KW, the current For the 4.5A or so, in the 380V three-phase balanced circuit, the power per 1KW, the current is about 2A, the above values can be calculated using the physical formula is very close to the results, so the electrician at work, in order to Do not remember those "cumbersome" formula, remember that these can. Then according to this algorithm to know: every 1 mm square cross-sectional area of the copper wire, if used in 220V single-phase circuit, you can safely carry 1KW load through the current, if used in three-phase balanced load (such as motor) Circuit, you can safely carry 2.5KW load through the current
Q:Can 110kv and 10kv cables co-share with trenches? What is the relevant specification?
With a straight pipe with a matching pipe (commonly known as the hoop), in order to prevent the joints at the slippery, PVC glue can be used after the smear. If the trouble, then use the electrical cloth cloth to the two tube package can also be strict.
