Voltages up to 35kv PVC/XLPE Power Cable

 

Brief Introduction

PVC/XLPE power cable is used to transmit and distribute power in power transmission and distribution system of 35kV or lower. It is generally applied to the fields including power, construction, mines, metallurgy, petrochemical industry and communication in complete replace of oil immersed paper insulated power cable and in partial replace of PVC insulated power cable.

 

Standard

The products can be produced according to our factory specification which is equivalent to the standard IEC60502.The factory can also design and manufacture special power cable according to the other standards required by the customers.

 

Properties of  PVC Power Cable

 

1.The long-time permissible working temperature of cable conductive core is not more than 70 degrees.

 

2.During short circuit (max permanent time is not more than 5 seconds), the max temperature of cable conductor is not more than 165°C.
3.The difference level of laying cable is not restricted.When laying the cable,ambient temperature is not lower than 0°C.
4.They have good chemical stability,and properties of acid resistance,alkali resistance,salt resistance,oil resistance,solvent resistance and flame resistance.

 

Properties of XLPE Power Cable

1.The highest allowed operating temperature of conductor for long-term working is 90 degrees.

2.In short circuit (Max long term is no more than 5 seconds). The highest temperature for conductor is no more than 250 degrees.

3.The cable is laid without horizontal drop limit. The environment temperature should be no lower than 0 when lay. Otherwise it should be preheated.

4.Excellent electrical performance, resistance to chemical corrosion.

5.Can stand advisable traction when laid.Can stand traction from Outside.Left low smoke halogen-free after burned.Retard the burning of the cable.

Q:The living room to the bedroom cable does not work
Submarine cables and ordinary power cables are used for power transmission, the general power cable in general steel armored after squeezing the outer jacket can be, the submarine cable in the outer jacket outside the cover and mixed with asphalt Steel armor layer to increase the mechanical strength and corrosion resistance when laying. Electrical technical parameters and the same as the ordinary power cable, the main consideration to provide cable laying when the submarine channel conditions and the sea environment. Another large length of the submarine power cable also consider the cable intermediate connector technology is reliable (in case of accidental damage or body failure). The difference between the submarine cable and the cable are said, if the need for submarine cable, in addition to the basic provision of electrical performance and other parameters need to provide laying environmental factors such as buried depth, sea water temperature, sea soil thermal resistance coefficient The
Q:What is the difference between VV22 and VV62?
Cross-linked power cable heating the main reason there are . the choice of continuous allowable current is less than the load of the maximum continuous current power cable; . the power cable in the implementation of the cable for cold contact, the use of crimping pliers die too large, leading to copper . the air switch input and output and cable copper nose connection, the choice of non-standard flat gasket or no spring gasket; . the air switch input and output side of the cable and cable core crimp is not solid and reliable; When the cable is connected to a strand, the air switch bolts are not tightened. . high-power UPS running, the filter cabinet is not put, n harmonic effects of cable overload, neutral overload, serious lead to cable breakdown, and a fire hazard. . the power cable along the building facade iron cabinet box laying, the surrounding environment is not ventilated, poor heat dissipation. Select the power cable should consider the following factors: . the rated voltage of the cable is greater than or equal to the rated power supply system power supply system; . the cable can continue to allow the current to be equal to or greater than the maximum load current load; . Power supply system short-circuit stability requirements; . according to the length of the cable to determine whether the voltage drop to meet the requirements; . the end of the line minimum short-circuit current should be able to protect the device reliable action. . a high degree of breakdown strength; . low dielectric loss; . a very high insulation resistance; . excellent resistance to discharge performance; . with a certain degree of flexibility and mechanical strength; . long-term stability of insulation.
Q:Power Cable Check Well b-type covers show what?
B-grade steel fiber concrete check covers are used for motor vehicle driving, parked urban roads, highways and parking lots C-grade steel fiber concrete check covers for slow lanes, residential quarters and sidewalks D-grade steel fiber concrete inspection covers for green belts and motor vehicles can not travel, parked lanes and venues
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:What is the interface between the power interface and the hard disk?
How can you pick up the computer, Internet cafes router connected to the tap, each tap has a lot of jacks, so you can pick up so many computers, you can carefully observe the Internet cafes, some iron box there are a lot of green In the flash is the tap
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:Paint trunking, galvanized trunking: that good? expensive? Their advantages and disadvantages?
Because the AC operation will produce eddy current, will make the steel pipe and cable heat burned. Single core refers to only one conductor in an insulating layer. When the voltage exceeds 35kV, most of the single-core cable, its core and metal shield layer relationship can be seen as a transformer primary winding coil and the relationship between the core. When the single-core cable core through the current when there will be magnetic lines linked to aluminum or metal shielding layer, so that both ends of the induced voltage. Power safety regulations: 35kV and below the voltage level of the cable are used at both ends of the grounding method, which is because most of these cables are three-core cable, in normal operation, the current flow through the three core sum of zero, in the aluminum There is no flux chain outside the package or metal shield, so that there is essentially no induced voltage at both ends of the aluminum or metal shield, so there is no induced current flowing through the aluminum or metal shield after grounding at both ends. But when the voltage exceeds 35kV, most of the single-core cable, its core and metal shield layer relationship can be seen as a transformer primary winding coil and the relationship between the core. When the single-core cable core through the current when there will be magnetic lines linked to aluminum or metal shielding layer, so that both ends of the induced voltage.
Q:What is the warranty period for wire and cable?
General cable shelf life is 10 years, look at the jacket and the insulation with or without cracks, shake the insulation resistance of the general do not breakdown can be used, but the best people to do some pressure test. The withstand voltage test must have been used.
Q:Water and electricity installation drawings in the kz on behalf of what material of the threading tube
No, without this provision, the purpose of blocking the cable piercing is to prevent the outside world on the adverse gas and other reasons of the invasion, in fact, as long as the purpose is achieved, the material selected or look at the situation, such as coal mine perforation must be sealed , The reason is to prevent the wind and air leakage, as well as when the outside world when the explosion of the substation damage, as well as their own substation has a fire source to prevent the development of fire to the outside world
Q:Dell laptop plug in the power supply usb can not be used, how is it?
It is generally not required to do so because the battery on the computer side of the charge side of the use of all right
