Parallel Cluster Overhead Insulated Cable


Product Introduction

Parallel cluster overhead insulated cable (hereinafter referred to as: parallel bundle conductor) is the national electric power company of rural power grid construction in the "tenth five-year plan of science and technology popularization and application of products.Our company draw lessons from foreign science and technology personnel application of wire beam, through the design and improvement of process and structure, research and development success, to fill the gaps in the product.
Low voltage power supply circuit reactance of the impedance, capacitive reactance and impedance.Parallel bundle conductor adopts three-phase four-wire power supply, make the match degree of three-phase unbalanced load fell to minimum, decrease the neutral line current, thereby reducing the resistance loss.Due to the use of close symmetrical division structure, lower the inductance of the wire, increase the line between the dielectric constant, electric capacity increased, make the circuit reactance slash, eventually achieve the goal of capacity loss.
Because the wires into cluster shape combination, and political force a single multiply, reduce single-phase break accident.In the wind, frost, etc when the tension between parallel insulation is not pressure, improve safety coefficient, the lightning protection, preventing electricity-stolen, prevent leakage effect obviously improved significantly.Due to its combination can be disruptive branch jumper easy, convenient varactor combination.According to the zero line identification, the phase sequence identification is clear, to prevent the fault phase sequence.Parallel bundle conductor line, reduce the tower, the cross arm and porcelain, save a lot of metal.Due to the insulation can decrease the height of tower, from trees, buildings, the influence of such a complex environment can be equipped completely save pole along the wall, low engineering cost.Also compared with the single line, the construction is simple, save work time, reduce the construction cost.Compared with the conventional pattern of overhead bare wires parallel bundle conductor has a low operating cost, long-term benefit is obvious advantage

Product Main Properties and Features:
Line loss is low, line loss.suggestions between 5-10%.
Saving time and labor for construction is convenient, and reduce the cost of installation.
Composite tensile force strong resistance, high safety, preventing electricity-stolen, prevent leakage.
Low engineering cost, reduce the pole, cross arm and porcelain, to reduce the pole height.

Products Adopt Standard:
Mixer GB12527-90 rated voltage up to and including 1 kv overhead insulated cable.
Mixer state power company acquired work "parallel cluster overhead insulated cable choose technical conditions"

Product Categories
According to the conductor material points: parallel cluster overhead insulated cable has two kinds of copper, aluminum core.
According to the insulation points: parallel cluster overhead insulated cable with weather resistance of polyvinyl chloride (PVC), polyethylene (PE) and crosslinking polyethylene of three kinds of insulation.
According to the structural type points: parallel cluster overhead insulated cable type well (BS1), star (BS2) type (BS3) three kinds of peace.

Products to pay:
My company according to customer requirements, to ensure timely delivery, and provide customer satisfaction of products and services.Parallel bundle conductor delivery length according to the agreement, both sides according to the customer request provide special hardware is complete.
Note: (1) the conductor: copper or aluminum (2) the connection bar: PVC or PE or (3) insulation: PVC or PE or

Q:Home improvement, the wire specifications generally how to choose? Lighting, sockets, air conditioning with a few square lines? Ground specifications can be lighter than the line of fire, zero line?
Sailing cold drill. The The Cool cold supreme. The The Pioneer (burner). The The
Q:With the patch panel how to deal with the line corresponding to the crystal line of the line order is what
The size of the jumper varies with the specifications of the bridge, which is uncertain; the so-called repetitive ground is at least two that is the beginning and end of the end, if the length is enough, the need for intermediate isolation to do the appropriate length of the ground. Stressed that a certain attention to the ground is connected to the power grid on the ground, not directly into the ground.
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 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:Why does the AC welding machine burn out the equipment?
The main role is to protect, the secondary role is insulation, there is a role is to decorate.
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:What are the varieties of wire and cable (detailed point)
Chien fiber optic transceivers fiber optic cable flange fiber box fiber jumpers welding machine. Our company: Qin Sheng network
Q:What is the fire wire pipe laying? What is the galvanized steel pipe?
Look at the computer and television, respectively, what interface are generally computer and television are more VGA, followed by HDMI, the new out there will be DisplayPort connection at both ends of the wire type is also very rich, VGA-VGA, HDMI-HDMI, etc. also Adapter cable, such as DVI to VGA and one according to the computer and television interface to select the wire, hard link established, win7 will automatically identify, I use the flagship version, feel better than XP. You can choose to clone the screen or expand the desktop and other operations, computer monitors Internet TV while watching movies, like.
Q:Can 110kv and 10kv cables co-share with trenches? What is the relevant specification?
The same is 1080P resolution, the computer with the TV is not full screen, it is possible that the frequency of computer graphics output and TV default frequency is different (the national standard is PAL50 Hz), so as long as the graphics output frequency into 50 Hz will be full screen. Win7 mouse right click, select the resolution, the remaining steps see below:
