Before we understand overhead cable accessories, we have to understand what the overhead cable is and what it is for. Definition of the overhead cables Overhead cables , as the name suggests, are cables built in the high air. Generally used in remote areas, exposed to outdoor. Overhead cables are generally used in medium and high voltage circuits that can transmit high-power currents. And the transmission efficiency is high, the transmission stability is better. Its installation, and troubleshooting are also easier than other cables. Accessories for the overhead cables There are three types of overhead cable accessories, they are suspension clips, strain clips, and insulated puncture clips Suspension clamps The suspension clip is able to hang the wire high above Suspension clip is a safe way to connect The clamp of the suspension clip is controllable, which can prevent the vibration and shock caused by high winds. Strain clamp The strain clamp acts as fixing fixed overhead line at both...

Popular types of control cables First understand what the control cable is and look at its definition Control cable is a main control and protect the line of the cable. Generally used for 450 / 750V voltage, mostly for industrial and mining enterprises and energy transportation departments. Generally, control cables are cables with insulated sleeves, mainly PVC and XLPE. Control cables are probably divided into three types CY control cable, YY control cable and SY control cable CY control cable The CY control cables are actually shielded cables It can only be transported in interference-free environments It has the advantage of the control and protection of the lines Its disadvantage is the poor mechanical resistance stress Its role is for the control of the power system of the railway transport network YY control cable YY control cables are actually non-screened control cables It can be used both for dry indoor and wet indoor environments. Its advantage has a wide range of availabili...

Cable definition and introduction A submarine cable is a type of cable that lies at the bottom of the sea wrapped in insulation.  It is mainly divided into submarine power cable and submarine communication cable. Subsea cables first appeared and were used between Britain and France in 1850. With the rapid development of The Times, the material of the submarine cable is also being updated. The current submarine cable's material is optical fiber, used to transmit telephone and Internet information. Optical guide fiber is a kind of fiber made of glass or plastic, which is a new type of transmission medium. Composition of the submarine cables The submarine cable is a complex cable, fourteen components of which are 1Conductor 2. Conductor shield 3. Insulation layer 4. Insulation shield 5. Semi-conductive resistance water band 6. Metal shielding 7.Copper belt 8. Water resistance belt 9.PE sheath 10. OP light unit 11. PE fill strip 12. PP rope 13. Steel wire armor 14. PP rope ●  C...

XLPE is a new insulation material. He had PE got by crosslinking.  So theoretically, his performance is better than the PE.  XLPE has been used in the cable industry since it was invented in the 1960 s and 1970 s.  Until now, XLPE has become head insulation in the cable industry. Here about the advantages and uses of XLPE  Advantages of XLPE cable XLPE   The advantages are as follows:   😊 I t can work at 90℃ high temperature for a long time . A nd  it  has excellent heat resistance . It also means it can withstand higher current ratings . 😊 I nsulation enhancement  and t he effect of temperature on the material is reduced . 😊  A ll-round improvement of mechanical characteristics,   no longer easy to crack due to environmental factors .  I mprove heat aging performance.  😊 R educe the harm to the environment,   in line with modern environmental protection requirements .  Easy operation and maintenance 😊 L ow ...

First, the overhead wires and underground cables function differently.   Overhead wire is main used to transmit high voltage electrical engery.  It' s often used to  transmit electrical energy to the tram and train. And also it can be used to provide energy to the launch pad.  Overhead wire often appears in remote areas. Underground cables is main used to city.  Because, urban land is becoming more and more scarce, and high- rise buildings in the city are emerging one after another. Therefore, overhead lines can not be built in the cities.  Only underground cables can be used.  Secondly, the overhead wires and underground cables have its own advantages and disadvantages. Overhead wires   Advantages  ⭐Price cheap ⭐Easy to install ⭐Transfer more current ⭐Easy to troubleshoot ⭐Long transmission distance  D isadvantages ⭐High safety hazard ⭐Easy to bad Underground cables  Advantages ⭐Less space occupied ⭐High safety fa...

The electrical power cable ’ s  process flow is not simple. The technological process of wire and cable is as follows. Copper rod -   Tie rod - stranding - insulation - spark - cable - inner sheath  - metal armoring  - outer sheat h. I'   ll explain these processes one by one . The copper rod is the raw materials, s o, it doesn'   t have to be explained .     Tie rod   The first step of making e lectrical p ower c able  is drawing. The Tie rod  means is that draw the rods and make it become various specification s ’   thin wire .   Stranding   The second step of making electrical power cable  is stranding. Stranding means stranding thin conductor wires together after drawing them.     Insulation   The third step of making electrical power cable  is insulation. Insulation means wrapping the stranded wire with insulating material.  There are many kinds of insulating materials. The...
