Our family friends, Tiffany and Justin are expecting baby #2 in July. They already have a daughter, Bella but are expecting a baby boy, Ian, this time. This last weekend her sisters hosted a Dr. Seuss shower which was super cute! Thanks Freitas girls for inviting me! It was a lot of fun.

OPGW 144
ReplyDeleteIntroduction to OPGW Cable -OPGW-24B1-150 OPGWOPGW-48B1-150
Optical fiber makes use of the difference of refractive index between core and cladding materials to transmit light energy in optical fiber, which has become a significant revolution in the history of communication. Optical fiber cable light in quality, small in size, has been adopted by the power system, in the substation and the central dispatching station between the transmission of dispatching telephone, telecontrol signals, relay protection, television images and other information. In order to improve the stability and reliability of optical fiber and cable, a composite structure of optical fiber and phase conductor, overhead ground wire and power cable has been developed abroad. OPGW optical cable because of the metal wire wrapped, so that the cable is more reliable, stable, firm, because of the overhead ground and cable composite as a whole, compared with the use of other optical cable, both shorten the construction period and save construction costs. In addition, if the OPGW made of aluminum clad steel wire or aluminum alloy wire is twisted, it is equivalent to setting up a good conductor overhead ground wire, which can receive many benefits such as reducing the latent power supply flow of transmission line, reducing the power frequency overvoltage, improving the interference and dangerous influence of power line on communication line, etc. Because of the characteristics of anti-electromagnetic interference and light weight of optical fiber, it can be installed on the top of transmission line tower without considering the best rack position and electromagnetic corrosion. Therefore, OPGW has high reliability, superior mechanical properties and low cost. This technique is particularly suitable and economical for new laying or replacement of existing ground cables.
