Splices are required in underground cable for a variety of reasons. They are required if digging equipment accidently hits a wire, or if the wire connection fails during the original installation. Regardless of why a splice is needed, the repair process is the same, and uses something called a...
While pulsed discharges are thought to be less damaging to cable than a steady dc voltage, utilities have concern that thumping can damage the unfailed sections of cable. When a thumper pulse breaks down the cable, the incoming surge shoots past the fault. When it reaches the open point, th...
once used to keep food cold, adapted to our modern era. In data centers, geothermal cooling uses a closed-loop pipe system with water or another coolant that runs through vertical wells underground, filled with a heat-transferring liquid. Iron Mountain...
signals have to travel vast distances through the atmosphere and space, resulting in higher latency compared to cable systems. In contrast,cable internettransmits data via underground or aerial cables directly connected to the user's modem,
to a hole that leads into the in-wall space to the master station. Since the cables from all the substations run to the master station, you need a larger entry hole through the floor space in the wall below the master station. Maneuver each cable up to the master station opening, and ...
Small two-pair cables run underground from the box to the houses. Sometimes the splices won't be quite this simple -- there will be a plastic or ceramic plate inside with a junction block instead of direct splices. So where does the 25-pair or 50-pair cable come from? If you hunt ...
Several different things can cause this to happen. The most familiar source is probably lightning, though it's actually one of the least common causes. When lightning strikes near a power line, whether it's underground, in a building or running along poles, the electrical energy can boost ...
Q: How do I know which plastic material to choose? A: This depends on application specifics. PVC is common for indoor use, while HDPE may be preferred for outdoor and underground applications due to its strength and flexibility. Q: What maintenance is required fo...
To understand what's happening, you have to go back 30 years, when the federal government was in the midst of building the internet. Miles of fiber optic cables were buried underground to connect households with cable broadband, extending networks run primarily by the military at the time. Tho...
This means, for instance, they’ll run a fibre optic cable through the existing underground duct if you have one for your copper phone line. Alternatively, they’ll connect you to the full fibre network with an overhead cable that follows the path of your existing phone line. A small ...
