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 ...
You will also find regulator banks located along the line, either underground or in the air. Above-ground regulator banks look like three garbage can-sized transformers held up by two utility poles. They regulate the voltage on the line to prevent undervoltage and overvoltage conditions. The reg...
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...
These elements all interact together, creating a fenced-in area that is invisible to the eye. When the dog approaches the underground wire, the collar will begin to beep. If the dog continues toward the wire, the collar will then deliver a mild electric shock (the correction), letting the...
