Product Description:


BV wire or plastic wire, name, general purpose single core hard conductor sheathed power cable.



B is represented categories, wire cloth, T on behalf of the conductor is: the copper conductor, V represents the insulation is: PVC.



1. Plastic wire type



BV is divided into: ZR - BV and NH - BV.



ZR - BV: copper core PVC insulated flame-retardant wire: insulation material with flame retardant, leaving no spontaneous combustion flame.



ZR - BV: flame retardant BV line is divided into A, B, C, D four grades, including class A is best, and so on, the most commonly used for ZB - BV.



NH - BV: copper core PVC insulated refractory wire: fire normally can be normal use.



2. The scientific name



Copper core PVC insulated wire



3. BV line USES



General purpose single core hard without sheathed cable conductor, is fit for ac voltage up to and including 450/750 power equipment, electrical appliances, instruments and equipment with cable wires.



4. BV line features



With acid and alkali resistance, oil resistance, moistureproof, mouldproof.



5. The wire type and name



1. The classification and USES is used for distribution of current use, as part of the wiring, expressed in the letter "B";



2. The conductor material is copper, with the letter "T", said the wiring of the copper conductor omitted;



3. The insulation material for PVC, with the letter "V";



4. Wiring structure is simple, in addition to the above three points, some still sheathed, sheath material is polyvinyl chloride (PVC) is also expressed in the letter "V"; Sheath materials for rubber is represented by the letter "X". No behind the sheath, and you don't have to say.



Such as the BVV said copper core PVC insulated PVC sheathed round wire.



6. Commonly used BV line model



BV line usually use insulation center metal conductor cross-sectional area to differentiate between the specifications. (such as the four square copper BV line cross section is 2.24 mm in diameter, according to the circular area calculation formula S = PI * r * r = 3.939 mm2)



Commonly used bv line type: 0.75 square, 1 square, 1.5 square, 2.5 square, four square, square, 10 square, square, 25 square, 35 square, 50 square, 70 square meters, 95 square meters, 120 square meters, 150 square meters, 185 square meters, 150 square etc. [1]


7. Other related content



BV cord with BVR said that BV rubber and copper wire with BX, said BV rubber aluminum expressed with BLX, BV plastic aluminum expressed in BLV, refractory BV line in NH - BV, flame retardant BV line with ZR - BV said



Purpose: ordinary insulated wire, household electrical wiring, it is the most commonly used type of wire.



With 100 square meters of new homes for the class, four square copper BV wires 200 meters, 2.5 400 m, 1.5 300 meters, 100 meters 1.5 square copper core of BV double color wire. The above said is not decorate condole top, if want to condole top 1.5 line even more



BV wire diameter side there are also several 0.2 0.3 0.4 0.5 number 300 400



8. Commonly used BV line color



Commonly used BV line colors: red, yellow, blue, green, black, white, double color (yellow, green, brown.



9. Bv plastic wire product standards



GB/T5023-2008 is equivalent to this standard IEC 60227-1997, JB/T 8734-2012 is equivalent to this standard IEC 227-1979

Q:Driving control cable hr What does it mean?
the working temperature +70 ℃; the middle of the cable or jacket can be used to strengthen the wire to avoid the use of the process of off Core of the phenomenon; the rated voltage of 500V; can be made into cold, weather resistance, oil and other characteristics of the cable Product Name: Rubber insulated rubber sheathed multi - core flexible cable
Q:What are the requirements for the construction of electrical wiring
Office with galvanized pipe, is the kind of iron, tooling should galvanized pipe, fire! Home can have, but galvanized are more expensive, so home improvement is less use!
Q:What is the meaning of the CPU in the computer configuration?
YJV: (copper) XLPE insulated PVC sheathed power cable, it is the power cable for transmission and distribution system; rated voltage from 0.6 / 1KV ~ 220KV or even higher; KVV: (copper) PVC Insulated PVC sheathed control cable, it is the control cable for control, monitoring, protection and other occasions, suitable for AC rated voltage 450 / 750V; two different uses of the cable, different insulation materials; YJV cable there are other related Model YJV22 / 32; ZR, NH, etc .; KVV cable nominal cross-section from 2.5 ~ 6mm2; core number 2 ~ 61 core range;
Q:Home improvement in the wire, there are 6 level, 4 level, 2.5, 1.5 of the. How many meters are each? The The The Where is the specific use? The The The
Into the household wire is outside the poles into the user's home, need to wear a single tube, but not for the sake of trouble, but also with the user's shunt wire with a thread. The scene of the light line, air conditioning lines, socket lines are part of the shunt wire, of course, can share a threading tube into the household.
Q:Motherboard CPU 8-pin, power is also 8-pin, only inserted 4-pin enough
Paint features: cheap easy to drop paint galvanized Features: slightly expensive glossy good, beautiful! I have installed these. Thought it was clean room recommended selection of galvanized, the price you can match online! Please adopt it ~!
Q:What is the closure of the pipe in the construction of hydropower?
BVV line refers to the copper core plastic sheath line; BV wire refers to the copper core PVC insulated wire. BV - bare copper wire, often wear pipe, bridge laying. BVV - jacket line, often apply. BV line referred to as plastic copper wire, name, general purpose single core hard conductor without sheath power cable. B represents the category, cloth wire, T represents the conductor: copper conductor, V represents the insulation is: polyvinyl chloride. Applicable to AC voltage 450 / 750V and below power plants, household appliances, instrumentation and telecommunications equipment with the cable wire.
Q:Is the bridge mounted above or below the water pipe? Is the top of the heating tube below?
According to Need for Speed recommended configuration, the host can be achieved
Q:What is the difference between HD and DVI lines?
RVS is copper core PVC insulated twisted pair RYS is insulated twisted phone line
Q:What is the difference between cable piping and wire piping?
KVVP shield is copper wire braid shielding ... KVVP2 shield is copper tape wrapped around the shield ... This is a detailed description of the GB / T9330-2008
Q:[Help] brake wire can be changed to half line alignment
10 floor things are positive solution, I was using, X treasure to find a local seller, like a 4 yuan a. If the line before and after the line across the board feel will be worse, with this change will be improved.
