1.  Products applications:

 

PVC insulated Power cables are fit for A.C rated voltages 600/1000V power transmission and distribution system.

 

2. Products standard:IEC 60502

 

3. Products characteristics:

 

--Long-term maximum working temperature of conductor should not be higher than 70°C, laying temperature should not be lower than 0 °C.

--Once short-circuit (the Max. duration 5s), the maximum conductor temperature does not be over 160 °C.

--Laying bending radius: Single-core and armored cables laying bending radius should not be less than 20 times of cable’s outer diameter value, however, multi-cores unarmored/armored cables laying bending radius should not be less than 15 times of cable’s outer diameter value.

5. Cable properties and use instructions:

 

--For unarmored cable, is suitable for laying in indoors, cable channel and conduit etc., such cables can’t bear strong mechanical force.

--For STA armored cable, is suitable for underground installation , which can withstand certain mechanical pressure,but can’t withstand mechanical tension,on the contrary, for SWA armored cable, is suitable for vertical installation, which can withstand certain mechanical tension, but can’t withstand mechanical pressure.

--For PVC sheath not only has excellent chemical corrosion resistance, but also has the properties of flame retardant and non water-absorption.

-- For single-core armored cables, non-magnetic material or Aluminum tape is main armored material, which only applies to D.C system.

Q:What does the cable (YJV-5 * 6) mean?
Full name: cable ZR-YJV22-4 * 16MM2ZR: flame retardant ----- YJV22: copper conductor cross-linked polyethylene insulated PVC sheathed double steel belt wrapped armored power cable --- 4 * 16MM2: 4 core, each core 16 square millimeters.
Q:What is the use of wire and cable per square meter of residential building?
You can use sc. if too long, or bend the best use of the bridge
Q:What is the difference between a pre-branch cable and a punched clip?
. soil buried pipe, including weak and fire, should be thick-walled galvanized steel pipe, that is, SC series of steel pipe, the best size is not less than SC. weak professional, decorative professional now basically use thin-walled galvanized steel pipe, that is JDG series steel pipe
Q:"Cable laying" cable cross-sectional area refers to the cable cross-sectional area, or refers to the copper core cross-sectional area
YJV22 indicates "copper core XLPE insulated, steel tape armored PVC sheathed power cable" 0.6 / 1KV indicates its pressure rating, 5 * 10 represents the cross-sectional area of each wire diameter Is square mm, referred to as the square, the diameter of the conversion is 4.05
Q:How long is the service life of the cable?
cable bridge and other pipes and other facilities shall not share a column (bracket)
Q:The difference between power cable and overhead cable
Insulation structure is not the same, the number of core is not the same. Power cable generally 3-4 phase, overhead cable general core. Power lines can be divided into overhead lines and cable lines. Overhead lines with less investment, easy construction and maintenance, easy maintenance and repair advantages, the disadvantage is the natural conditions (wind, snow, ice, lightning, etc.) have a greater threat to operational safety. In order to save the country's construction funds, the general use of overhead lines is appropriate. However, when the conditions are subject to restrictions (such as overhead lines laid in difficult or special requirements), the use of cable lines. Cable and overhead lines compared to poor heat dissipation, it should be considered in the short-circuit conditions of thermal stability. Therefore, in addition to high-voltage cable cross-section in accordance with the economic current density, allowing voltage loss, long-term allowable current selection, but also according to short-circuit thermal stability conditions for verification.
Q:Can cable TV signal lines and network cables be placed in the same line when upgrading? What happens if you are in the same line? Thank you.
Wired do not need to set what ah, directly to the network cable can be inserted into the network port
Q:Calculation method of wire and cable outer diameter
Usually check the table, in the cable samples or manual check.
Q:What is the difference between public relations firms and media companies?
The width of the cable bridge international standard: cable bridge width ≤ 150 ~ 1.0150 800 ~ 2.2
Q:Emergency power off after the computer can not open the machine, an open is a lot of words appear seconds limit, you can
There is a collection of. There is a direct connection, there are T then. Electric well trunking without cover, how can be connected
