WebFeb 19, 2024 · Which is better underground transmission or overhead transmission? Cost of underground cables (e.g. HVDC) are three times higher compare to overhead lines (e.g. 400 KV). Moreover laying or burying cost of underground lines are greater compare to overhead lines. It is difficult to find and repair the wire breaks in case of failure of system. WebAug 23, 2015 · In the case of a lightning strike, an Ethernet cable can only transmit so much current, which the surge suppressors stand a chance of absorbing/diverting. If that happens and somehow destroys the cable and both surge arrestors, you just pull new cable and buy a couple of new surge arrestors.
WebIn all cases, the purpose of a high-quality lightning protection system is to: Secure critical infrastructure and assets.
