DC Side Bridge
Changing the polarity of the power supply to DC motor is used to change the direction of rotation. Apart from changing the rotation direction, the H-bridge can provide additional operation modes, "brake" and "free run until frictional stop".OverviewAn H-bridge is an that switches the polarity of a voltage applied to a load. These circuits are often used in and other applications to allow DC motors to run forwards or backwards. The name is de. H-bridges are available as, or can be built from. The term H-bridge is derived from the typical graphical representation of such a circuit. An.

Cable blowing during optical cable construction in communication pipelines
Cable blowing is the process of installation of optical fiber cable into a pre-installed duct. In this article, we'll guide you through the entire fiber optic cable blowing procedure, highlighting the essential tools, the advantages over traditional methods, and the common challenges. Cable installation by using high speed air flow combined with additional mechanical pushing force is called as “blowing or jetting”. This method is particularly common in the deployment of Fiber-to-the-Home (FTTH) networks and last-mile access. Cable pay off the top of reel: This helps installer to have control and manage the pay-off, do not pay cable from the bottom of the reel which can cause loosening of the windings and loss of control.
