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:Yjv22 cable laying pipe when the casing with plastic or steel pipe
Second, the laying of the bracket, the power cable should be placed in the upper control cable, but 1000 volts below the power cable and control cable can be laid side by side
Q:Is the power cable considered a fixed asset?
Belong to the fixed assets of an integral part, because for self-use so the input tax is not deducted, the input tax can be transferred out of the entry
Q:Copper core power cable models which several kinds
They have two kinds of total use, one is the transmission current, one is the transmission signal
Q:What is the radiation of the laser scanning scanner?
The shield has two types of semi-conductive shield and metal shield
Q:A sub-eight splitter, behind the link ONU equipment, which also need to add fiber patch panels, or can be directly connected?
How do you not say that the three-phase system or two-phase system, if the two systems is the power in addition to the voltage is equal to the current, three-phase power per kilowatt multiplied by 2 equal to the current, such as 220V, 3000W / 220V = 13.6A, 380V, 3KW * 2 = 6A. Wire 10 square below, each square can be with 5A, which is the calculation of aluminum core line, copper wire line operator count, 220V aluminum core must be greater than 2.5 square, copper core must be greater than 1.5 square, 380V with aluminum core The line must be greater than 1.5 square and the copper wire must be greater than 1 square. At this time should also consider the equipment to start the current and increase the appropriate diameter.
Q:Ask you a question: how the computer CD-ROM power supply 5V and 12V two lines? Another audio and video cable which group?
Cable bridge at both ends to be installed across the ground wire, ground wire diameter can not be less than 16mm2. Wire ends and wire ends of the middle box to be installed at both ends of the ground wire, grounding wire diameter can not be less than 6mm2. Full length bridge with the grounding system connected to not less than 2. Cable bridge is divided into trough, tray and ladder-type, mesh and other structures, by the bracket, arm and installation accessories and other components. Can be set up independently, can also be attached to a variety of structures (structures) and corridor stent, reflecting the structure is simple, handsome in appearance, flexible configuration and easy maintenance features, all parts are required galvanized, installed in the building Outside the bridge, if it is in the vicinity of the sea or belong to the corrosion area, the material must have anti-corrosion, moisture resistance, good adhesion, high impact resistance of the physical characteristics. According to the relevant provisions of the specification, galvanized cable bridge for a good grounding. galvanized cable tray direct board each fixed bolt contact resistance should be less than 0.005Ω, then the cable bridge can be used as a ground trunk (dusting cable tray should not be used as a grounding line), the resistance of each cable bridge can be the following formula Calculate: r = ρ · L / S where: ρ = 15 × 10Ω-6 / cm (20 ℃); L = length calculated by 100mm; S = cross-sectional area of ​​cm2. The unit resistance value of the ladder on the pallet is shown in Table 2. The unit resistance value of the cable duct is shown in Table 3 The resistance of each ladder (or each cable slot) after the installation of the cable tray is the total: R = R (r + 1 / 3r ') where: R - ladder, that is, (cable trough) total length of the total resistance (mΩ); r - ladder unit length resistance (mΩ / m)
Q:PVC pipe on the GV.215-16 (C) What does it mean
TC line laying is the use of wire steel pipe laying. Wire steel pipe is a thin-walled tube, the nominal diameter is the outer diameter of the pipe. SC line laying is the use of ordinary welded steel pipe laying. Ordinary welded steel pipe is thick-walled tube, nominal diameter is tube diameter.
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:What is the wiring principle in the home improvement circuit?
Section 4 "Downhole Cable" Article 466 No cable should be laid in the total return airway and the dedicated return airway
Q:What kind of material should be selected for the fixing bracket of the cable trunking
Should be caused by power line interference. You can buy a shield with the copper wrapped in audio cable and then placed next to the power cord can be, electronic city should have to sell.
