Air Blown Cable VS Ordinary Optical Fiber Cable
The air blown cable greatly improves the utilization efficiency of the tube hole, so it has more market applications in the world. The micro-cable and micro-tube technology (JETnet) is the same as the traditional air-blown fiber optic cable technology in terms of laying principle, that is, "mothe...Read more -
How to improve the thermal stability of OPGW cable?
Today, GL talks about how to improve the common measures of OPGW cable thermal stability: 1. Shunt line method The price of OPGW cable is very high, and it is not economical to simply increase the cross-section to bear the short-circuit current. It is commonly used to set up a lightning protectio...Read more -
Analysis of the influence of poles and towers on the erection of ADSS optical cables
Adding ADSS cables to the 110kV line that has been in operation, the main problem is that in the original design of the tower, there is no consideration at all to allow the addition of any objects outside the design, and it will not leave enough space for the ADSS cable. The so-called space not o...Read more -
