Q:Galvanized wire tube buried to do anti - corrosion do

The former core is a single strand of hard copper wire, which is a multi-strand copper wire.

Q:Is high pressure cable head stress tube important?

In the event of heavy rain, we often encounter power outages, in many cities are common. In fact, this is mainly rain into the cable tube, soak for a long time, the cable will be aging and then caused by power failure. This problem can be avoided, but for a long time the relevant departments do not attach importance to the construction of the city to consider incomplete, there is no plugging the cable pipeline. At present, the solution is to solve the program is the application of WQBZ inflatable cable pipe sealing system, not only waterproof rodent control, but also easy to repair, safe and reliable, domestic this is a complete science and technology done well.

Q:I know that kind of concrete row pipe, glass steel pipe. I would like to know when the cable buried, crossing the SC pipe laying, such as wearing 2x2SC100 steel pipe laying, this section of the pipe is not considered row of pipe? Is there any pipe made of steel pipe? More

Left and right in the fire in the ground, the socket L for the fire N is zero for the last one, but you'd better use the pen to test which is the line of fire

Q:2 [YJV22-4 * 185] -SC150-FC is the representative of the two YJV22-4 * 185 cable at the same time wear SC150 mean? Or are they wearing two tubes? why? More

Electrical discharge pipe in the installation of steel pipe wiring, should be noted that can not be used in places with severe corrosion

Q:Cable protection tube where the need to play a trumpet what role

Is not a zero line is not a ah. Three zero lines.

Q:Cable YJV-3 * 70 + 2 * 35 general wear large SC tube? Ask you.

Into the end ,,, is to use a core and pigtail welding. The The This is the end ah. The The Into the end of the cable in the end? The This is not so understanding, has been completed by the cable, need to connect a fiber optic cable, and then into the end? So that is ,,, has been in the end of the cable there, with the network from the switch to the optical transceiver ,,, and then from the optical transceiver and a fiber optic cable fusion pigtail. The The

Q:Cable bridge out of the box to do the casing, how to do

RVV is a copper core PVC insulated PVC sheathed flexible cable, feeling that should belong to the power cable (line) of a

Q:Why does the wire tube make the jumper

Move, transport than metal pipe and cement pipe easy and convenient Construction and installation is simple, both easy and effort Corrosion resistance, insulation, non-magnetic, acid, alkali, flame retardant, anti-static Bending elastic modulus is good, completely solve the metal pipe perishable, no distortion of the characteristics of elasticity, but also to overcome the easy aging of the plastic tube, poor impact resistance Water resistance is good, can be used in wet or long-term use of water is not bad Due to the specific properties of glass fiber reinforced plastic, the life of the glass pipe over 50 years NCBB said glass fiber reinforced plastic cable protection tube, is also a kind of glass fiber reinforced casing, 100 × 5 that diameter 100mm, 5 side by side

Q:The laying distance of the cable laying cable

The wire is plastic, is a polymer material, do not dissolve in water, will not affect, but there is no connector, will make the joints rust, causing poor contact because the water will cause the circuit will lead to short circuit, burn other thing.

Q:Outdoor buried cable is not buried directly buried, what is the requirement

According to the wiring position, 1KV has a middle connector and terminal head; 10 and 35KV, divided into intermediate connector, indoor terminal and outdoor terminal According to the number of cable core, 1KV has a single core, two core, three core, four core, five core, 10kV above a single core and three core accessories According to the cable characteristics, with armored, without armored PVC, XLPE cable, and oil-immersed cable Communication cable Heat shrink tubing for intermediate and end plugging of communication cables According to the use of the cable, there are: overhead (RSB / RSY), Buried (RSBJ) and air pressure maintenance (RSBA series) According to the joint features, there are: longitudinal package (zipper) and round tube communication cable connector According to the characteristics of the cable, there are ordinary HYA city cable, with oil-immersed cable (RSBJT series) The above hope to help you, are dry goods, fifteen years of industry experience
