Product Description:

Product properties:  

1. The long-term working temperature allowed by overhead conducting wires is 70°C;  

2. When there are large-span rare weather conditions and there is less ice coating occurring in heavy ice areas, maximum stress the lowest point of the conductor sag should not be more than 60% of instantaneous destructive power;

3. When the wires are connected, strands around the connecting pipe should not bulge, otherwise the strands of wires in operation will be unevenly stressed, after the joints are pressed, outlets of connecting pipe should be covered with moisture-proof paint to prevent corrosion; 

4. When the wires are installed, sag stress of all the wires at the same gear should be the same, and within the range permitted by the limited distances to the ground and exceeding the distance for protection of building, the conducting wire stress can be higher by 10-15% than normal tension.  Scope of application:  This product is applied to overhead power transmission and distribution lines.


Scope of application:

This product is applied to overhead power transmission and distribution lines.

Q:"Cable laying" cable cross-sectional area refers to the cable cross-sectional area, or refers to the copper core cross-sectional area
Low-voltage power cable, also known as: low-voltage power cable. The voltage rating is 0.6 / 1KV. National Standard No .: GB / T-2008. The voltage rating of the control cable is 450 / 750V. National Standard No .: GB / T9330-2008. The voltage rating of these two cables, the country has a clear standard. Can not be changed.
Q:1.2 meters below the road can use pvc tube wear armor cable?
The former bv4 square copper wire is a single strand of hard copper wire, the latter BV4 square copper wire is multi-strand soft copper wire. Core (coredwire), with steel sheath for the outer tube filled with iron alloy powder to do core material, cross-section for the circular or rectangular line body. Also known as cored wire. It is used as a steel-making furnace outside the refining of the feed method to add refining agent and alloying agent. Can be directly added to the deep steel, the molten steel for deoxidation, desulfurization, degassing and non-metallic inclusions denatured treatment, to eliminate the aluminum deoxidized steel in the continuous casting steel | iron when the nozzle plugging the problem. As the deep addition of alloying elements in the molten steel, so the alloying element recovery rate is high and stable, the steel components can be fine-tuned to the best range. The reproducibility of the results is good.
Q:The telephone line, TV line, cable, power lines are worn to a wire tube, what will happen?
This is the wiring of the cable wiring formulas: the next five is 10 square below the current per square 5A current wiring, one hundred and twenty is more than 100 square per square 2A, 25335 three circles, meaning 10 (Excluding) or more, 25 square feet per square 3A wiring, 35 square (inclusive) or more, 100 square (excluding) the following per square 4A line, that is, 25 square feet, 35 square feet per square by 3A or 4A wiring line.
Q:Hello, ask about how to charge the electric car at home, use a few square millimeters of wire? How high is the demand for family lines, thank you!
PLC and computer communication cable, different manufacturers of PLC connection is not the same
Q:The TV shows no signal. The What is the reason for this?
The domestic general by the following parts in order, some parts can be omitted: 1: category, use the first letter with the Chinese alphabet, such as K on behalf of the control cable, C on behalf of the marine cable Q car ignition line D power cable Y Mobile rubber sheathed cable H welding machine cable 2: conductor with the first letter of the Chinese alphabet said: such as T for the copper, L for the aluminum LG for the ACSR 3: Insulation material with the letter code, such as V for the PVCY Polyethylene 4: Sheath with the letter of the letter code with 35: feature code used in the first letter of Chinese spells, such as the circle with R, soft R, flat B, flat with B6: outer sheath with the number that: 22 the first representative of the steel armor, the second representative of the PVC jacket 7: derived code with a number or symbol, such as BV-withered Sichuan Fen boil let go wind sand dust 90 said temperature 90 degrees BV line can be omitted Generally have: D power cable T copper R round like VV. you control the order of the above carefully understand, which omitted the 1.2.5 three, you should see clearly.
Q:Choose the configuration of good or bad computer graphics card memory processor, etc., how to choose a different manufacturers
Is not the power cord is loose, or is the motherboard battery power
Q:TV tiger when the set-top box when tv / ay look for a look on the platform
Cable 2 * NH-KW2 * 1.. the first two said two cables, KW is KVV said PVC insulated jacket control cable,
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.
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
Q:What is the power cable accessories used to do?
Do not know what you want to ask? What about your situation? Normal or pregnant? Normal this radiation does not affect what, if it is pregnant, this is far away from the best. Pregnancy is most needed to stay away from the microwave!
